Safety Instructions Warnings and NotesEN 4 L032L AA2

2 Safety Instructions Warnings and Notes

Index of this chapter21 Safety Instructions22 Maintenance Instructions23 Warnings24 Notes

21 Safety Instructions

Safety regulations require that during a repairbull Connect the set to the Mains (AC Power) via an isolation

transformer (gt 800 VA)bull Replace safety components indicated by the symbol

only by components identical to the original ones Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard

bull Wear safety goggles when you replace the CRT Safety regulations require that after a repair the set must be returned in its original condition Pay in particular attention to the following points bull General repair instruction as a strict precaution we advise

you to re-solder the solder connections through which the horizontal deflection current is flowing In particular this is valid for the1 Pins of the line output transformer (LOT)2 Fly-back capacitor(s)3 S-correction capacitor(s)4 Line output transistor5 Pins of the connector with wires to the deflection coil6 Other components through which the deflection current

flows

Note This re-soldering is advised to prevent bad connections due to metal fatigue in solder connections and is therefore only necessary for television sets more than two years oldbull Route the wire trees and EHT cable correctly and secure

them with the mounted cable clampsbull Check the insulation of the Mains (AC Power) lead for

external damage bull Check the strain relief of the mains (AC Power) cord for

proper function to prevent the cord from touching the CRT hot components or heat sinks

bull Check the electrical DC resistance between the Mains (AC Power) plug and the secondary side (only for sets which have a Mains (AC Power) isolated power supply) 1 Unplug the Mains (AC Power) cord and connect a wire

between the two pins of the Mains (AC Power) plug 2 Set the Mains (AC Power) switch to the on position

(keep the Mains (AC Power) cord unplugged) 3 Measure the resistance value between the pins of the

Mains (AC Power) plug and the metal shielding of the tuner or the aerial connection on the set The reading should be between 45 Mohm and 12 Mohm

4 Switch off the set and remove the wire between the two pins of the Mains (AC Power) plug

bull Check the cabinet for defects to avoid touching of any inner parts by the customer

22 Maintenance Instructions

We recommend a maintenance inspection carried out by qualified service personnel The interval depends on the usage conditionsbull When a customer uses the set under normal

circumstances for example in a living room the recommended interval is three to five years

bull When a customer uses the set in an environment with higher dust grease or moisture levels for example in a kitchen the recommended interval is one year

bull The maintenance inspection includes the following actions

1 Perform the ldquogeneral repair instructionrdquo noted above2 Clean the power supply and deflection circuitry on the

chassis3 Clean the picture tube panel and the neck of the picture

tube

23 Warnings

bull In order to prevent damage to ICs and transistors avoid all high voltage flashovers In order to prevent damage to the picture tube use the method shown in figure ldquoDischarge picture tuberdquo to discharge the picture tube Use a high voltage probe and a multi-meter (position VDC) Discharge until the meter reading is 0 V (after approx 30 s)

Figure 2-1 Discharge picture tube

bull All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD ) Careless handling during repair can reduce life drastically Make sure that during repair you are connected with the same potential as the mass of the set by a wristband with resistance Keep components and tools also at this same potential Available ESD protection equipment ndash Complete kit ESD3 (small tablemat wristband

connection box extension cable and earth cable) 4822 310 10671

ndash Wristband tester 4822 344 13999 bull Be careful during measurements in the high voltage

section bull Never replace modules or other components while the unit

is switched on bull When you align the set use plastic rather than metal tools

This will prevent any short circuits and the danger of a circuit becoming unstable

24 Notes

241 General

bull Measure the voltages and waveforms with regard to the chassis (= tuner) ground () or hot ground () depending on the tested area of circuitry The voltages and waveforms shown in the diagrams are indicative Measure them in the Service Default Mode (see chapter 5) with a colour bar signal and stereo sound (L 3 kHz R 1 kHz unless stated otherwise) and picture carrier at 47525 MHz for PAL or 6125 MHz for NTSC (channel 3)

bull Where necessary measure the waveforms and voltages with () and without () aerial signal Measure the voltages in the power supply section both in normal operation () and in stand-by () These values are indicated by means of the appropriate symbols

bull The semiconductors indicated in the circuit diagram and in the parts lists are interchangeable per position with the

V

E_06532_007eps250304

Directions for Use EN 5L032L AA 3

semiconductors in the unit irrespective of the type indication on these semiconductors

242 Schematic Notes

bull All resistor values are in ohms and the value multiplier is often used to indicate the decimal point location (eg 2K2 indicates 22 kohm)

bull Resistor values with no multiplier may be indicated with either an E or an R (eg 220E or 220R indicates 220 ohm)

bull All capacitor values are given in micro-farads (micro= x10-6) nano-farads (n= x10-9) or pico-farads (p= x10-12)

bull Capacitor values may also use the value multiplier as the decimal point indication (eg 2p2 indicates 22 pF)

bull An asterisk () indicates component usage varies Refer to the diversity tables for the correct values

bull The correct component values are listed in the Spare Parts List Therefore always check this list when there is any doubt

243 Lead Free Solder

Philips CE is going to produce lead-free sets (PBF) from 112005 onwards

Figure 2-2 Lead-free logo

This sign normally has a diameter of 6 mm but if there is less space on a board also 3 mm is possible Regardless of this logo (is not always present) one must treat all sets from this date onwards according to the following rules

Due to lead-free technology some rules have to be respected by the workshop during a repairbull Use only lead-free soldering tin Philips SAC305 with order

code 0622 149 00106 If lead-free solder paste is required please contact the manufacturer of your soldering equipment In general use of solder paste within workshops should be avoided because paste is not easy to store and to handle

bull Use only adequate solder tools applicable for lead-free soldering tin The solder tool must be able

ndash To reach at least a solder-tip temperature of 400degCndash To stabilise the adjusted temperature at the solder-tipndash To exchange solder-tips for different applications

bull Adjust your solder tool so that a temperature around 360degC - 380degC is reached and stabilised at the solder joint Heating time of the solder-joint should not exceed ~ 4 sec Avoid temperatures above 400degC otherwise wear-out of tips will rise drastically and flux-fluid will be destroyed To avoid wear-out of tips switch ldquooffrdquo unused equipment or reduce heat

bull Mix of lead-free soldering tinparts with leaded soldering tinparts is possible but PHILIPS recommends strongly to avoid mixed regimes If not to avoid clean carefully the solder-joint from old tin and re-solder with new tin

bull Use only original spare-parts listed in the Service-Manuals Not listed standard material (commodities) has to be purchased at external companies

bull For sets produced before 112005 containing leaded soldering tin and components all needed spare parts will be available till the end of the service period For the repair of such sets nothing changes

In case of doubt whether the board is lead-free or not (or with mixed technologies) you can use the following methodbull Always use the highest temperature to solder when using

SAC305 (see also instructions below)bull De-solder thoroughly (clean solder joints to avoid mix of

two alloys)Caution For BGA-ICs you must use the correct temperature-profile which is coupled to the 12NC For an overview of these profiles visit the website wwwatyourservicecephilipscom (needs subscription but is not available for all regions)You will find this and more technical information within the Magazine chapter Workshop informationFor additional questions please contact your local repair help desk

244 Practical Service Precautions

bull It makes sense to avoid exposure to electrical shock While some sources are expected to have a possible dangerous impact others of quite high potential are of limited current and are sometimes held in less regard

bull Always respect voltages While some may not be dangerous in themselves they can cause unexpected reactions that are best avoided Before reaching into a powered TV set it is best to test the high voltage insulation It is easy to do and is a good service precaution

54 ComPair

541 Introduction

ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products ComPair is a further development on the European DST (service remote control) which allows faster and more accurate diagnostics ComPair has three big advantagesbull ComPair helps you to quickly get an understanding on how

to repair the chassis in a short time by guiding you systematically through the repair procedures

bull ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas You do not have to know anything about I2C commands yourself because ComPair takes care of this

bull ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available When ComPair is installed together with the SearchMan electronic manual of the defective chassis schematics and PWBs are only a mouse click away

542 Specifications

ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product The ComPair interface box is connected to the PC via a serial or RS232 cable In this chassis the ComPair interface box and the TV communicate via a bi-directional service cable via the service

Service Modes Error Codes and Fault Finding EN 9L032L AA 5

connector (located on the Main panel (see figure Top view Mono Carrier in chapter 8 Alignments) The ComPair faultfinding program is able to determine the problem of the defective television ComPair can gather diagnostic information in two waysbull Automatic (by communication with the television)

ComPair can automatically read out the contents of the entire error buffer Diagnosis is done on I2C level ComPair can access the I2C bus of the television ComPair can send and receive I2C commands to the micro controller of the television In this way it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set

bull Manually (by asking questions to you) Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extent When this is not the case ComPair will guide you through the faultfinding tree by asking you questions (eg Does the screen give a picture Click on the correct answer YES NO) and showing you examples (eg Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope) You can answer by clicking on a link (eg text or a waveform picture) that will bring you to the next step in the faultfinding process

By a combination of automatic diagnostics and an interactive question answer procedure ComPair will enable you to find most problems in a fast and effective way Besides fault finding ComPair provides some additional features likebull Up- or downloading of pre-setsbull Managing of pre-set listsbull Emulation of the Dealer Service Tool (DST)bull If both ComPair and SearchMan (Electronic Service

Manual) are installed all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink Example Measure the DC-voltage on capacitor C2568 (SchematicPanel) at the Mono-carrier ndash Click on the Panel hyperlink to automatically show the

PWB with a highlighted capacitor C2568 ndash Click on the Schematic hyperlink to automatically

show the position of the highlighted capacitor

543 How to Connect ComPair

1 First install the ComPair Browser software (see the Quick Reference Card for installation instructions)

2 Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ldquoPCrdquo) of the ComPair interface

3 Connect the AC power adapter to the supply connector (marked with ldquoPOWER 9V DCrdquo) on the ComPair interface

4 Switch the ComPair interface OFF5 Switch the television set OFF (remove the AC power)6 Connect the ComPair interface cable between the

connector on the rear side of the ComPair interface (marked with ldquoI2Crdquo) and the ComPair connector on the mono carrier (see figure Top view Mono Carrier in chapter 8 Alignments)

7 Plug the AC power adapter in the AC power outlet and switch on the interface The green and red LEDs light up together The red LED extinguishes after approx 1 second while the green LED remains lit

545 Error Buffer

The error code buffer contains all detected errors since the last time the buffer was erased The buffer is written from left to right When an error occurs that is not yet in the error code buffer it is written at the left side and all other errors shift one position to the right

546 How To Read the Error Buffer

You can read the error buffer in 3 waysbull On screen via the SDAM (only if you have a picture)

Examplesndash ERROR 0 0 0 0 0 No errors detectedndash ERROR 6 0 0 0 0 Error code 6 is the last and only

detected errorndash ERROR 9 6 0 0 0 Error code 6 was first detected and

error code 9 is the last detected (newest) errorbull Via the blinking LED procedure (when you have no

picture) See next paragraphbull Via ComPair

547 How to Clear the Error Buffer

The error code buffer is cleared in the following casesbull By activation of the CLEAR command in the SDAM menubull If the content of the error buffer has not changed for 50

hours it resets automatically

NoteWhen leaving SDAM by disconnecting the set from AC power the error buffer is not reset

55 Error Codes

In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)

Table 5-3 Error Code Table

56 The Blinking LED Procedure

Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence

finishes with a LED blink of 3 sbull The sequence starts again

Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again

57 Protections

If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of

the set in a predefined way and adjustment of the set via a menu and with the help of test patterns

58 Repair Tips

Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain

Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective

bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged

bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496

bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions

bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

83 Software Alignments and Settings

The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

831 OPTIONS

Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

button on the remote control transmitter or the local keyboard

ndash Disconnect the television set from AC power for at least ten seconds

How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

value (see first column value between brackets in table below) When an option bit is disabled its value is 0

3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

described in this chapter For the other circuit descriptions see the manual of the L012L AA

bull Figures can deviate slightly from the actual situation due to different set executions

bull For a good understanding of the following circuit descriptions please use the block diagram in chapter 6 andor the electrical diagrams in chapter 7 Where necessary you will find a separate drawing for clarification

91 Introduction

The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

92 Source Selection

The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

done entirely by the UOC and will only be able to select one external audio source

bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

921 Switching Function for Stereo IO

Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

922 Switching Function for Mono IO

For the Mono configuration only one input pin is available for the UOC

Video Source SelectionThe video switching is similar to the section above

Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

93 Audio

This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

931 Processing

This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

932 Amplifier

The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9

The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

933 AVL (Automatic Volume Limiting)

The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

Figure 9-1 AVL timing diagram

934 Mute

The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV

AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed

bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all

initialization processes are finishedbull When the set is going to STANDBY MUTE must be

activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier

mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC

For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder

95 Synchronization

Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized

with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information

971 Introduction

The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

972 Derived Voltages

The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

98 Control

The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

981 I2C-Bus

The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

982 User Interface

The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

983 IO Selection

For the control of the input and output selections there are three lines

STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

984 Power Supply Control

The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

Figure 9-2 Block diagram of power supply interface with UOC

PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

985 Protection Events

Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

    2 Safety Instructions Warnings and Notes

    Index of this chapter21 Safety Instructions22 Maintenance Instructions23 Warnings24 Notes

    21 Safety Instructions

    Safety regulations require that during a repairbull Connect the set to the Mains (AC Power) via an isolation

    transformer (gt 800 VA)bull Replace safety components indicated by the symbol

    only by components identical to the original ones Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard

    bull Wear safety goggles when you replace the CRT Safety regulations require that after a repair the set must be returned in its original condition Pay in particular attention to the following points bull General repair instruction as a strict precaution we advise

    you to re-solder the solder connections through which the horizontal deflection current is flowing In particular this is valid for the1 Pins of the line output transformer (LOT)2 Fly-back capacitor(s)3 S-correction capacitor(s)4 Line output transistor5 Pins of the connector with wires to the deflection coil6 Other components through which the deflection current

    flows

    Note This re-soldering is advised to prevent bad connections due to metal fatigue in solder connections and is therefore only necessary for television sets more than two years oldbull Route the wire trees and EHT cable correctly and secure

    them with the mounted cable clampsbull Check the insulation of the Mains (AC Power) lead for

    external damage bull Check the strain relief of the mains (AC Power) cord for

    proper function to prevent the cord from touching the CRT hot components or heat sinks

    bull Check the electrical DC resistance between the Mains (AC Power) plug and the secondary side (only for sets which have a Mains (AC Power) isolated power supply) 1 Unplug the Mains (AC Power) cord and connect a wire

    between the two pins of the Mains (AC Power) plug 2 Set the Mains (AC Power) switch to the on position

    (keep the Mains (AC Power) cord unplugged) 3 Measure the resistance value between the pins of the

    Mains (AC Power) plug and the metal shielding of the tuner or the aerial connection on the set The reading should be between 45 Mohm and 12 Mohm

    4 Switch off the set and remove the wire between the two pins of the Mains (AC Power) plug

    bull Check the cabinet for defects to avoid touching of any inner parts by the customer

    22 Maintenance Instructions

    We recommend a maintenance inspection carried out by qualified service personnel The interval depends on the usage conditionsbull When a customer uses the set under normal

    circumstances for example in a living room the recommended interval is three to five years

    bull When a customer uses the set in an environment with higher dust grease or moisture levels for example in a kitchen the recommended interval is one year

    bull The maintenance inspection includes the following actions

    1 Perform the ldquogeneral repair instructionrdquo noted above2 Clean the power supply and deflection circuitry on the

    chassis3 Clean the picture tube panel and the neck of the picture

    tube

    23 Warnings

    bull In order to prevent damage to ICs and transistors avoid all high voltage flashovers In order to prevent damage to the picture tube use the method shown in figure ldquoDischarge picture tuberdquo to discharge the picture tube Use a high voltage probe and a multi-meter (position VDC) Discharge until the meter reading is 0 V (after approx 30 s)

    Figure 2-1 Discharge picture tube

    bull All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD ) Careless handling during repair can reduce life drastically Make sure that during repair you are connected with the same potential as the mass of the set by a wristband with resistance Keep components and tools also at this same potential Available ESD protection equipment ndash Complete kit ESD3 (small tablemat wristband

    connection box extension cable and earth cable) 4822 310 10671

    ndash Wristband tester 4822 344 13999 bull Be careful during measurements in the high voltage

    section bull Never replace modules or other components while the unit

    is switched on bull When you align the set use plastic rather than metal tools

    This will prevent any short circuits and the danger of a circuit becoming unstable

    24 Notes

    241 General

    bull Measure the voltages and waveforms with regard to the chassis (= tuner) ground () or hot ground () depending on the tested area of circuitry The voltages and waveforms shown in the diagrams are indicative Measure them in the Service Default Mode (see chapter 5) with a colour bar signal and stereo sound (L 3 kHz R 1 kHz unless stated otherwise) and picture carrier at 47525 MHz for PAL or 6125 MHz for NTSC (channel 3)

    bull Where necessary measure the waveforms and voltages with () and without () aerial signal Measure the voltages in the power supply section both in normal operation () and in stand-by () These values are indicated by means of the appropriate symbols

    bull The semiconductors indicated in the circuit diagram and in the parts lists are interchangeable per position with the

    V

    E_06532_007eps250304

    Directions for Use EN 5L032L AA 3

    semiconductors in the unit irrespective of the type indication on these semiconductors

    242 Schematic Notes

    bull All resistor values are in ohms and the value multiplier is often used to indicate the decimal point location (eg 2K2 indicates 22 kohm)

    bull Resistor values with no multiplier may be indicated with either an E or an R (eg 220E or 220R indicates 220 ohm)

    bull All capacitor values are given in micro-farads (micro= x10-6) nano-farads (n= x10-9) or pico-farads (p= x10-12)

    bull Capacitor values may also use the value multiplier as the decimal point indication (eg 2p2 indicates 22 pF)

    bull An asterisk () indicates component usage varies Refer to the diversity tables for the correct values

    bull The correct component values are listed in the Spare Parts List Therefore always check this list when there is any doubt

    243 Lead Free Solder

    Philips CE is going to produce lead-free sets (PBF) from 112005 onwards

    Figure 2-2 Lead-free logo

    This sign normally has a diameter of 6 mm but if there is less space on a board also 3 mm is possible Regardless of this logo (is not always present) one must treat all sets from this date onwards according to the following rules

    Due to lead-free technology some rules have to be respected by the workshop during a repairbull Use only lead-free soldering tin Philips SAC305 with order

    code 0622 149 00106 If lead-free solder paste is required please contact the manufacturer of your soldering equipment In general use of solder paste within workshops should be avoided because paste is not easy to store and to handle

    bull Use only adequate solder tools applicable for lead-free soldering tin The solder tool must be able

    ndash To reach at least a solder-tip temperature of 400degCndash To stabilise the adjusted temperature at the solder-tipndash To exchange solder-tips for different applications

    bull Adjust your solder tool so that a temperature around 360degC - 380degC is reached and stabilised at the solder joint Heating time of the solder-joint should not exceed ~ 4 sec Avoid temperatures above 400degC otherwise wear-out of tips will rise drastically and flux-fluid will be destroyed To avoid wear-out of tips switch ldquooffrdquo unused equipment or reduce heat

    bull Mix of lead-free soldering tinparts with leaded soldering tinparts is possible but PHILIPS recommends strongly to avoid mixed regimes If not to avoid clean carefully the solder-joint from old tin and re-solder with new tin

    bull Use only original spare-parts listed in the Service-Manuals Not listed standard material (commodities) has to be purchased at external companies

    bull For sets produced before 112005 containing leaded soldering tin and components all needed spare parts will be available till the end of the service period For the repair of such sets nothing changes

    In case of doubt whether the board is lead-free or not (or with mixed technologies) you can use the following methodbull Always use the highest temperature to solder when using

    SAC305 (see also instructions below)bull De-solder thoroughly (clean solder joints to avoid mix of

    two alloys)Caution For BGA-ICs you must use the correct temperature-profile which is coupled to the 12NC For an overview of these profiles visit the website wwwatyourservicecephilipscom (needs subscription but is not available for all regions)You will find this and more technical information within the Magazine chapter Workshop informationFor additional questions please contact your local repair help desk

    244 Practical Service Precautions

    bull It makes sense to avoid exposure to electrical shock While some sources are expected to have a possible dangerous impact others of quite high potential are of limited current and are sometimes held in less regard

    bull Always respect voltages While some may not be dangerous in themselves they can cause unexpected reactions that are best avoided Before reaching into a powered TV set it is best to test the high voltage insulation It is easy to do and is a good service precaution

    54 ComPair

    541 Introduction

    ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products ComPair is a further development on the European DST (service remote control) which allows faster and more accurate diagnostics ComPair has three big advantagesbull ComPair helps you to quickly get an understanding on how

    to repair the chassis in a short time by guiding you systematically through the repair procedures

    bull ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas You do not have to know anything about I2C commands yourself because ComPair takes care of this

    bull ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available When ComPair is installed together with the SearchMan electronic manual of the defective chassis schematics and PWBs are only a mouse click away

    542 Specifications

    ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product The ComPair interface box is connected to the PC via a serial or RS232 cable In this chassis the ComPair interface box and the TV communicate via a bi-directional service cable via the service

    Service Modes Error Codes and Fault Finding EN 9L032L AA 5

    connector (located on the Main panel (see figure Top view Mono Carrier in chapter 8 Alignments) The ComPair faultfinding program is able to determine the problem of the defective television ComPair can gather diagnostic information in two waysbull Automatic (by communication with the television)

    ComPair can automatically read out the contents of the entire error buffer Diagnosis is done on I2C level ComPair can access the I2C bus of the television ComPair can send and receive I2C commands to the micro controller of the television In this way it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set

    bull Manually (by asking questions to you) Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extent When this is not the case ComPair will guide you through the faultfinding tree by asking you questions (eg Does the screen give a picture Click on the correct answer YES NO) and showing you examples (eg Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope) You can answer by clicking on a link (eg text or a waveform picture) that will bring you to the next step in the faultfinding process

    By a combination of automatic diagnostics and an interactive question answer procedure ComPair will enable you to find most problems in a fast and effective way Besides fault finding ComPair provides some additional features likebull Up- or downloading of pre-setsbull Managing of pre-set listsbull Emulation of the Dealer Service Tool (DST)bull If both ComPair and SearchMan (Electronic Service

    Manual) are installed all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink Example Measure the DC-voltage on capacitor C2568 (SchematicPanel) at the Mono-carrier ndash Click on the Panel hyperlink to automatically show the

    PWB with a highlighted capacitor C2568 ndash Click on the Schematic hyperlink to automatically

    show the position of the highlighted capacitor

    543 How to Connect ComPair

    1 First install the ComPair Browser software (see the Quick Reference Card for installation instructions)

    2 Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ldquoPCrdquo) of the ComPair interface

    3 Connect the AC power adapter to the supply connector (marked with ldquoPOWER 9V DCrdquo) on the ComPair interface

    4 Switch the ComPair interface OFF5 Switch the television set OFF (remove the AC power)6 Connect the ComPair interface cable between the

    connector on the rear side of the ComPair interface (marked with ldquoI2Crdquo) and the ComPair connector on the mono carrier (see figure Top view Mono Carrier in chapter 8 Alignments)

    7 Plug the AC power adapter in the AC power outlet and switch on the interface The green and red LEDs light up together The red LED extinguishes after approx 1 second while the green LED remains lit

    545 Error Buffer

    The error code buffer contains all detected errors since the last time the buffer was erased The buffer is written from left to right When an error occurs that is not yet in the error code buffer it is written at the left side and all other errors shift one position to the right

    546 How To Read the Error Buffer

    You can read the error buffer in 3 waysbull On screen via the SDAM (only if you have a picture)

    Examplesndash ERROR 0 0 0 0 0 No errors detectedndash ERROR 6 0 0 0 0 Error code 6 is the last and only

    detected errorndash ERROR 9 6 0 0 0 Error code 6 was first detected and

    error code 9 is the last detected (newest) errorbull Via the blinking LED procedure (when you have no

    picture) See next paragraphbull Via ComPair

    547 How to Clear the Error Buffer

    The error code buffer is cleared in the following casesbull By activation of the CLEAR command in the SDAM menubull If the content of the error buffer has not changed for 50

    hours it resets automatically

    NoteWhen leaving SDAM by disconnecting the set from AC power the error buffer is not reset

    Service Modes Error Codes and Fault FindingEN 10 L032L AA5

    55 Error Codes

    In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)

    Table 5-3 Error Code Table

    56 The Blinking LED Procedure

    Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence

    finishes with a LED blink of 3 sbull The sequence starts again

    Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again

    57 Protections

    If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of

    the set in a predefined way and adjustment of the set via a menu and with the help of test patterns

    58 Repair Tips

    Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain

    Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective

    bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged

    bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496

    bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions

    bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

    81 General Alignment Conditions

    Perform all electrical adjustments under the following conditionsbull AC voltage and frequency according to countrys

    standardbull Connect the television set to the AC power via an isolation

    transformerbull Allow the television set to warm up for approximately 20

    minutesbull Measure the voltages and waveforms in relation to chassis

    ground (with the exception of the voltages on the primary side of the power supply) Never use heatsinks as ground

    bull Test probe Ri gt 10 M ohm Ci lt 25 pFbull Use an isolated trimmerscrewdriver to perform the

    1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

    2 Use the MENU UPDOWN keys to highlight the WHITE TONE sub menu

    3 Press the MENU LEFTRIGHT key to enter the WHITE TONE sub menu

    4 In the WHITE TONE sub menu press the MENU UPDOWN keys to select NORMAL RED NORMAL GREEN or NORMAL BLUE

    5 Use the MENU LEFTRIGHT keys to set the values of NORMAL RED NORMAL GREEN and NORMAL BLUE to 40

    6 Press the MENU button twice to enter the normal user menu

    7 In the normal user menu use the MENU UPDOWN keys to highlight the PICTURE sub menu (if necessary)

    8 Press the MENU LEFTRIGHT keys to enter the PICTURE sub menu

    9 Use the MENU UPDOWN keys to select CONTRAST Be sure to record the current value of CONTRAST

    10 Use the MENU LEFTRIGHT keys to set the value of CONTRAST to 0

    11 Use the MENU UPDOWN keys to select BRIGHTNESS Be sure to record the current value of BRIGHTNESS

    12 Use the MENU LEFTRIGHT keys to set the value of BRIGHTNESS to minimum (OSD just visible in a dark room)

    13 Press the MENU button twice to return to the top level SDAM menu

    14 Press the OSDSTATUS button to hide the SDAM onscreen display (S indication remains visible) This to avoid interferences during the waveform measurements

    15 Connect the RF output of a video pattern generator to the antenna input and input a black picture test pattern to the television set

    16 Set the oscilloscope to 50 Vdiv and the time base to 02 milliseconds (external triggering on the positive vertical pulse with a 101 probe)

    17 Ground the scope at the CRT panel and connect a 1001 probe to one of the cathodes of the picture tube socket (pin 7= Red pin 9= Green and pin 3= Blue see also schematic diagram B1) Measure the level of the black current measuring pulses These are the second line (Red) third line (Green) and fourth line (Blue) directly after the frame blanking (see figure Vcut-off) Remark This chassis is using a TDA93XX UOC series These use two different measuring pulses at each of the R G and B outputs The above-mentioned level applies to the pulse with the lowest level of each gun

    18 Select the cathode with the highest VDC value for the alignment Adjust the Vcut-off of this gun with the SCREEN potentiometer (see figure Top view family board) on the LOT to the correct value (see table Vg2 alignment values)

    19 Press the OSDSTATUS button to display the SDAM onscreen display

    20 Press the MENU button to enter the normal user menu21 In the normal user menu use the MENU UPDOWN keys

    83 Software Alignments and Settings

    The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

    831 OPTIONS

    Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

    How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

    1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

    2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

    3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

    4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

    5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

    6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

    press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

    8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

    button on the remote control transmitter or the local keyboard

    ndash Disconnect the television set from AC power for at least ten seconds

    ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

    button on the remote control transmitter or the local keyboard

    Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

    How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

    enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

    value (see first column value between brackets in table below) When an option bit is disabled its value is 0

    3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

    91 Introduction

    The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

    The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

    92 Source Selection

    The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

    done entirely by the UOC and will only be able to select one external audio source

    bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

    921 Switching Function for Stereo IO

    Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

    922 Switching Function for Mono IO

    For the Mono configuration only one input pin is available for the UOC

    Video Source SelectionThe video switching is similar to the section above

    Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

    93 Audio

    This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

    931 Processing

    This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

    932 Amplifier

    The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

    Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9

    The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

    933 AVL (Automatic Volume Limiting)

    The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

    Figure 9-1 AVL timing diagram

    934 Mute

    The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV

    AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed

    bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all

    initialization processes are finishedbull When the set is going to STANDBY MUTE must be

    activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier

    mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC

    TDA9853H3 Above conditions refers to both mono and stereo sets

    94 Video

    For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder

    95 Synchronization

    Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized

    with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information

    96 Deflection

    For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)

    97 Power Supply

    For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable

    971 Introduction

    The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

    972 Derived Voltages

    The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

    98 Control

    The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

    981 I2C-Bus

    The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

    982 User Interface

    The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

    983 IO Selection

    For the control of the input and output selections there are three lines

    STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

    STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

    SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

    984 Power Supply Control

    The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

    STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

    This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

    Figure 9-2 Block diagram of power supply interface with UOC

    PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

    985 Protection Events

    Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

    Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

      Index of this chapter21 Safety Instructions22 Maintenance Instructions23 Warnings24 Notes

      21 Safety Instructions

      Safety regulations require that during a repairbull Connect the set to the Mains (AC Power) via an isolation

      transformer (gt 800 VA)bull Replace safety components indicated by the symbol

      only by components identical to the original ones Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard

      bull Wear safety goggles when you replace the CRT Safety regulations require that after a repair the set must be returned in its original condition Pay in particular attention to the following points bull General repair instruction as a strict precaution we advise

      you to re-solder the solder connections through which the horizontal deflection current is flowing In particular this is valid for the1 Pins of the line output transformer (LOT)2 Fly-back capacitor(s)3 S-correction capacitor(s)4 Line output transistor5 Pins of the connector with wires to the deflection coil6 Other components through which the deflection current

      flows

      Note This re-soldering is advised to prevent bad connections due to metal fatigue in solder connections and is therefore only necessary for television sets more than two years oldbull Route the wire trees and EHT cable correctly and secure

      them with the mounted cable clampsbull Check the insulation of the Mains (AC Power) lead for

      external damage bull Check the strain relief of the mains (AC Power) cord for

      proper function to prevent the cord from touching the CRT hot components or heat sinks

      bull Check the electrical DC resistance between the Mains (AC Power) plug and the secondary side (only for sets which have a Mains (AC Power) isolated power supply) 1 Unplug the Mains (AC Power) cord and connect a wire

      between the two pins of the Mains (AC Power) plug 2 Set the Mains (AC Power) switch to the on position

      (keep the Mains (AC Power) cord unplugged) 3 Measure the resistance value between the pins of the

      Mains (AC Power) plug and the metal shielding of the tuner or the aerial connection on the set The reading should be between 45 Mohm and 12 Mohm

      4 Switch off the set and remove the wire between the two pins of the Mains (AC Power) plug

      bull Check the cabinet for defects to avoid touching of any inner parts by the customer

      22 Maintenance Instructions

      We recommend a maintenance inspection carried out by qualified service personnel The interval depends on the usage conditionsbull When a customer uses the set under normal

      circumstances for example in a living room the recommended interval is three to five years

      bull When a customer uses the set in an environment with higher dust grease or moisture levels for example in a kitchen the recommended interval is one year

      bull The maintenance inspection includes the following actions

      1 Perform the ldquogeneral repair instructionrdquo noted above2 Clean the power supply and deflection circuitry on the

      chassis3 Clean the picture tube panel and the neck of the picture

      tube

      23 Warnings

      bull In order to prevent damage to ICs and transistors avoid all high voltage flashovers In order to prevent damage to the picture tube use the method shown in figure ldquoDischarge picture tuberdquo to discharge the picture tube Use a high voltage probe and a multi-meter (position VDC) Discharge until the meter reading is 0 V (after approx 30 s)

      Figure 2-1 Discharge picture tube

      bull All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD ) Careless handling during repair can reduce life drastically Make sure that during repair you are connected with the same potential as the mass of the set by a wristband with resistance Keep components and tools also at this same potential Available ESD protection equipment ndash Complete kit ESD3 (small tablemat wristband

      connection box extension cable and earth cable) 4822 310 10671

      ndash Wristband tester 4822 344 13999 bull Be careful during measurements in the high voltage

      section bull Never replace modules or other components while the unit

      is switched on bull When you align the set use plastic rather than metal tools

      This will prevent any short circuits and the danger of a circuit becoming unstable

      24 Notes

      241 General

      bull Measure the voltages and waveforms with regard to the chassis (= tuner) ground () or hot ground () depending on the tested area of circuitry The voltages and waveforms shown in the diagrams are indicative Measure them in the Service Default Mode (see chapter 5) with a colour bar signal and stereo sound (L 3 kHz R 1 kHz unless stated otherwise) and picture carrier at 47525 MHz for PAL or 6125 MHz for NTSC (channel 3)

      bull Where necessary measure the waveforms and voltages with () and without () aerial signal Measure the voltages in the power supply section both in normal operation () and in stand-by () These values are indicated by means of the appropriate symbols

      bull The semiconductors indicated in the circuit diagram and in the parts lists are interchangeable per position with the

      V

      semiconductors in the unit irrespective of the type indication on these semiconductors

      242 Schematic Notes

      bull All resistor values are in ohms and the value multiplier is often used to indicate the decimal point location (eg 2K2 indicates 22 kohm)

      bull Resistor values with no multiplier may be indicated with either an E or an R (eg 220E or 220R indicates 220 ohm)

      bull All capacitor values are given in micro-farads (micro= x10-6) nano-farads (n= x10-9) or pico-farads (p= x10-12)

      bull Capacitor values may also use the value multiplier as the decimal point indication (eg 2p2 indicates 22 pF)

      243 Lead Free Solder

      Philips CE is going to produce lead-free sets (PBF) from 112005 onwards

      Figure 2-2 Lead-free logo

      This sign normally has a diameter of 6 mm but if there is less space on a board also 3 mm is possible Regardless of this logo (is not always present) one must treat all sets from this date onwards according to the following rules

      Due to lead-free technology some rules have to be respected by the workshop during a repairbull Use only lead-free soldering tin Philips SAC305 with order

      code 0622 149 00106 If lead-free solder paste is required please contact the manufacturer of your soldering equipment In general use of solder paste within workshops should be avoided because paste is not easy to store and to handle

      bull Use only adequate solder tools applicable for lead-free soldering tin The solder tool must be able

      ndash To reach at least a solder-tip temperature of 400degCndash To stabilise the adjusted temperature at the solder-tipndash To exchange solder-tips for different applications

      bull Adjust your solder tool so that a temperature around 360degC - 380degC is reached and stabilised at the solder joint Heating time of the solder-joint should not exceed ~ 4 sec Avoid temperatures above 400degC otherwise wear-out of tips will rise drastically and flux-fluid will be destroyed To avoid wear-out of tips switch ldquooffrdquo unused equipment or reduce heat

      bull Mix of lead-free soldering tinparts with leaded soldering tinparts is possible but PHILIPS recommends strongly to avoid mixed regimes If not to avoid clean carefully the solder-joint from old tin and re-solder with new tin

      bull Use only original spare-parts listed in the Service-Manuals Not listed standard material (commodities) has to be purchased at external companies

      bull For sets produced before 112005 containing leaded soldering tin and components all needed spare parts will be available till the end of the service period For the repair of such sets nothing changes

      In case of doubt whether the board is lead-free or not (or with mixed technologies) you can use the following methodbull Always use the highest temperature to solder when using

      SAC305 (see also instructions below)bull De-solder thoroughly (clean solder joints to avoid mix of

      two alloys)Caution For BGA-ICs you must use the correct temperature-profile which is coupled to the 12NC For an overview of these profiles visit the website wwwatyourservicecephilipscom (needs subscription but is not available for all regions)You will find this and more technical information within the Magazine chapter Workshop informationFor additional questions please contact your local repair help desk

      244 Practical Service Precautions

      bull It makes sense to avoid exposure to electrical shock While some sources are expected to have a possible dangerous impact others of quite high potential are of limited current and are sometimes held in less regard

      bull Always respect voltages While some may not be dangerous in themselves they can cause unexpected reactions that are best avoided Before reaching into a powered TV set it is best to test the high voltage insulation It is easy to do and is a good service precaution

      54 ComPair

      541 Introduction

      ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products ComPair is a further development on the European DST (service remote control) which allows faster and more accurate diagnostics ComPair has three big advantagesbull ComPair helps you to quickly get an understanding on how

      to repair the chassis in a short time by guiding you systematically through the repair procedures

      bull ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas You do not have to know anything about I2C commands yourself because ComPair takes care of this

      bull ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available When ComPair is installed together with the SearchMan electronic manual of the defective chassis schematics and PWBs are only a mouse click away

      542 Specifications

      ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product The ComPair interface box is connected to the PC via a serial or RS232 cable In this chassis the ComPair interface box and the TV communicate via a bi-directional service cable via the service

      Service Modes Error Codes and Fault Finding EN 9L032L AA 5

      connector (located on the Main panel (see figure Top view Mono Carrier in chapter 8 Alignments) The ComPair faultfinding program is able to determine the problem of the defective television ComPair can gather diagnostic information in two waysbull Automatic (by communication with the television)

      ComPair can automatically read out the contents of the entire error buffer Diagnosis is done on I2C level ComPair can access the I2C bus of the television ComPair can send and receive I2C commands to the micro controller of the television In this way it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set

      bull Manually (by asking questions to you) Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extent When this is not the case ComPair will guide you through the faultfinding tree by asking you questions (eg Does the screen give a picture Click on the correct answer YES NO) and showing you examples (eg Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope) You can answer by clicking on a link (eg text or a waveform picture) that will bring you to the next step in the faultfinding process

      By a combination of automatic diagnostics and an interactive question answer procedure ComPair will enable you to find most problems in a fast and effective way Besides fault finding ComPair provides some additional features likebull Up- or downloading of pre-setsbull Managing of pre-set listsbull Emulation of the Dealer Service Tool (DST)bull If both ComPair and SearchMan (Electronic Service

      Manual) are installed all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink Example Measure the DC-voltage on capacitor C2568 (SchematicPanel) at the Mono-carrier ndash Click on the Panel hyperlink to automatically show the

      PWB with a highlighted capacitor C2568 ndash Click on the Schematic hyperlink to automatically

      show the position of the highlighted capacitor

      543 How to Connect ComPair

      1 First install the ComPair Browser software (see the Quick Reference Card for installation instructions)

      2 Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ldquoPCrdquo) of the ComPair interface

      3 Connect the AC power adapter to the supply connector (marked with ldquoPOWER 9V DCrdquo) on the ComPair interface

      4 Switch the ComPair interface OFF5 Switch the television set OFF (remove the AC power)6 Connect the ComPair interface cable between the

      connector on the rear side of the ComPair interface (marked with ldquoI2Crdquo) and the ComPair connector on the mono carrier (see figure Top view Mono Carrier in chapter 8 Alignments)

      7 Plug the AC power adapter in the AC power outlet and switch on the interface The green and red LEDs light up together The red LED extinguishes after approx 1 second while the green LED remains lit

      545 Error Buffer

      The error code buffer contains all detected errors since the last time the buffer was erased The buffer is written from left to right When an error occurs that is not yet in the error code buffer it is written at the left side and all other errors shift one position to the right

      546 How To Read the Error Buffer

      You can read the error buffer in 3 waysbull On screen via the SDAM (only if you have a picture)

      Examplesndash ERROR 0 0 0 0 0 No errors detectedndash ERROR 6 0 0 0 0 Error code 6 is the last and only

      detected errorndash ERROR 9 6 0 0 0 Error code 6 was first detected and

      error code 9 is the last detected (newest) errorbull Via the blinking LED procedure (when you have no

      picture) See next paragraphbull Via ComPair

      547 How to Clear the Error Buffer

      The error code buffer is cleared in the following casesbull By activation of the CLEAR command in the SDAM menubull If the content of the error buffer has not changed for 50

      hours it resets automatically

      NoteWhen leaving SDAM by disconnecting the set from AC power the error buffer is not reset

      Service Modes Error Codes and Fault FindingEN 10 L032L AA5

      55 Error Codes

      In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)

      Table 5-3 Error Code Table

      56 The Blinking LED Procedure

      Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence

      finishes with a LED blink of 3 sbull The sequence starts again

      Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again

      57 Protections

      If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of

      the set in a predefined way and adjustment of the set via a menu and with the help of test patterns

      58 Repair Tips

      Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain

      Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective

      bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged

      bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496

      bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions

      bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

      83 Software Alignments and Settings

      The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

      831 OPTIONS

      Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

      How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

      1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

      2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

      3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

      4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

      5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

      6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

      press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

      8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

      button on the remote control transmitter or the local keyboard

      ndash Disconnect the television set from AC power for at least ten seconds

      ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

      button on the remote control transmitter or the local keyboard

      Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

      How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

      91 Introduction

      The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

      The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

      92 Source Selection

      The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

      done entirely by the UOC and will only be able to select one external audio source

      bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

      921 Switching Function for Stereo IO

      Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

      922 Switching Function for Mono IO

      For the Mono configuration only one input pin is available for the UOC

      Video Source SelectionThe video switching is similar to the section above

      Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

      93 Audio

      This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

      931 Processing

      This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

      932 Amplifier

      The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

      Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9

      The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

      933 AVL (Automatic Volume Limiting)

      The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

      Figure 9-1 AVL timing diagram

      934 Mute

      The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV

      AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed

      bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all

      initialization processes are finishedbull When the set is going to STANDBY MUTE must be

      activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier

      mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC

      TDA9853H3 Above conditions refers to both mono and stereo sets

      94 Video

      For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder

      95 Synchronization

      Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized

      with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information

      96 Deflection

      For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)

      97 Power Supply

      For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable

      971 Introduction

      The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

      972 Derived Voltages

      The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

      98 Control

      The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

      981 I2C-Bus

      The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

      982 User Interface

      The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

      983 IO Selection

      For the control of the input and output selections there are three lines

      STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

      STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

      SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

      984 Power Supply Control

      The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

      STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

      This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

      Figure 9-2 Block diagram of power supply interface with UOC

      PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

      985 Protection Events

      Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

      Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

        2 Safety Instructions Warnings and Notes

        Index of this chapter21 Safety Instructions22 Maintenance Instructions23 Warnings24 Notes

        21 Safety Instructions

        Safety regulations require that during a repairbull Connect the set to the Mains (AC Power) via an isolation

        transformer (gt 800 VA)bull Replace safety components indicated by the symbol

        only by components identical to the original ones Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard

        bull Wear safety goggles when you replace the CRT Safety regulations require that after a repair the set must be returned in its original condition Pay in particular attention to the following points bull General repair instruction as a strict precaution we advise

        you to re-solder the solder connections through which the horizontal deflection current is flowing In particular this is valid for the1 Pins of the line output transformer (LOT)2 Fly-back capacitor(s)3 S-correction capacitor(s)4 Line output transistor5 Pins of the connector with wires to the deflection coil6 Other components through which the deflection current

        flows

        Note This re-soldering is advised to prevent bad connections due to metal fatigue in solder connections and is therefore only necessary for television sets more than two years oldbull Route the wire trees and EHT cable correctly and secure

        them with the mounted cable clampsbull Check the insulation of the Mains (AC Power) lead for

        external damage bull Check the strain relief of the mains (AC Power) cord for

        proper function to prevent the cord from touching the CRT hot components or heat sinks

        bull Check the electrical DC resistance between the Mains (AC Power) plug and the secondary side (only for sets which have a Mains (AC Power) isolated power supply) 1 Unplug the Mains (AC Power) cord and connect a wire

        between the two pins of the Mains (AC Power) plug 2 Set the Mains (AC Power) switch to the on position

        (keep the Mains (AC Power) cord unplugged) 3 Measure the resistance value between the pins of the

        Mains (AC Power) plug and the metal shielding of the tuner or the aerial connection on the set The reading should be between 45 Mohm and 12 Mohm

        4 Switch off the set and remove the wire between the two pins of the Mains (AC Power) plug

        bull Check the cabinet for defects to avoid touching of any inner parts by the customer

        22 Maintenance Instructions

        We recommend a maintenance inspection carried out by qualified service personnel The interval depends on the usage conditionsbull When a customer uses the set under normal

        circumstances for example in a living room the recommended interval is three to five years

        bull When a customer uses the set in an environment with higher dust grease or moisture levels for example in a kitchen the recommended interval is one year

        bull The maintenance inspection includes the following actions

        1 Perform the ldquogeneral repair instructionrdquo noted above2 Clean the power supply and deflection circuitry on the

        chassis3 Clean the picture tube panel and the neck of the picture

        tube

        23 Warnings

        bull In order to prevent damage to ICs and transistors avoid all high voltage flashovers In order to prevent damage to the picture tube use the method shown in figure ldquoDischarge picture tuberdquo to discharge the picture tube Use a high voltage probe and a multi-meter (position VDC) Discharge until the meter reading is 0 V (after approx 30 s)

        Figure 2-1 Discharge picture tube

        bull All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD ) Careless handling during repair can reduce life drastically Make sure that during repair you are connected with the same potential as the mass of the set by a wristband with resistance Keep components and tools also at this same potential Available ESD protection equipment ndash Complete kit ESD3 (small tablemat wristband

        connection box extension cable and earth cable) 4822 310 10671

        ndash Wristband tester 4822 344 13999 bull Be careful during measurements in the high voltage

        section bull Never replace modules or other components while the unit

        is switched on bull When you align the set use plastic rather than metal tools

        This will prevent any short circuits and the danger of a circuit becoming unstable

        24 Notes

        241 General

        bull Measure the voltages and waveforms with regard to the chassis (= tuner) ground () or hot ground () depending on the tested area of circuitry The voltages and waveforms shown in the diagrams are indicative Measure them in the Service Default Mode (see chapter 5) with a colour bar signal and stereo sound (L 3 kHz R 1 kHz unless stated otherwise) and picture carrier at 47525 MHz for PAL or 6125 MHz for NTSC (channel 3)

        bull Where necessary measure the waveforms and voltages with () and without () aerial signal Measure the voltages in the power supply section both in normal operation () and in stand-by () These values are indicated by means of the appropriate symbols

        bull The semiconductors indicated in the circuit diagram and in the parts lists are interchangeable per position with the

        V

        E_06532_007eps250304

        Directions for Use EN 5L032L AA 3

        semiconductors in the unit irrespective of the type indication on these semiconductors

        242 Schematic Notes

        bull All resistor values are in ohms and the value multiplier is often used to indicate the decimal point location (eg 2K2 indicates 22 kohm)

        bull Resistor values with no multiplier may be indicated with either an E or an R (eg 220E or 220R indicates 220 ohm)

        bull All capacitor values are given in micro-farads (micro= x10-6) nano-farads (n= x10-9) or pico-farads (p= x10-12)

        bull Capacitor values may also use the value multiplier as the decimal point indication (eg 2p2 indicates 22 pF)

        bull An asterisk () indicates component usage varies Refer to the diversity tables for the correct values

        bull The correct component values are listed in the Spare Parts List Therefore always check this list when there is any doubt

        243 Lead Free Solder

        Philips CE is going to produce lead-free sets (PBF) from 112005 onwards

        Figure 2-2 Lead-free logo

        This sign normally has a diameter of 6 mm but if there is less space on a board also 3 mm is possible Regardless of this logo (is not always present) one must treat all sets from this date onwards according to the following rules

        Due to lead-free technology some rules have to be respected by the workshop during a repairbull Use only lead-free soldering tin Philips SAC305 with order

        code 0622 149 00106 If lead-free solder paste is required please contact the manufacturer of your soldering equipment In general use of solder paste within workshops should be avoided because paste is not easy to store and to handle

        bull Use only adequate solder tools applicable for lead-free soldering tin The solder tool must be able

        ndash To reach at least a solder-tip temperature of 400degCndash To stabilise the adjusted temperature at the solder-tipndash To exchange solder-tips for different applications

        bull Adjust your solder tool so that a temperature around 360degC - 380degC is reached and stabilised at the solder joint Heating time of the solder-joint should not exceed ~ 4 sec Avoid temperatures above 400degC otherwise wear-out of tips will rise drastically and flux-fluid will be destroyed To avoid wear-out of tips switch ldquooffrdquo unused equipment or reduce heat

        bull Mix of lead-free soldering tinparts with leaded soldering tinparts is possible but PHILIPS recommends strongly to avoid mixed regimes If not to avoid clean carefully the solder-joint from old tin and re-solder with new tin

        bull Use only original spare-parts listed in the Service-Manuals Not listed standard material (commodities) has to be purchased at external companies

        bull For sets produced before 112005 containing leaded soldering tin and components all needed spare parts will be available till the end of the service period For the repair of such sets nothing changes

        In case of doubt whether the board is lead-free or not (or with mixed technologies) you can use the following methodbull Always use the highest temperature to solder when using

        SAC305 (see also instructions below)bull De-solder thoroughly (clean solder joints to avoid mix of

        two alloys)Caution For BGA-ICs you must use the correct temperature-profile which is coupled to the 12NC For an overview of these profiles visit the website wwwatyourservicecephilipscom (needs subscription but is not available for all regions)You will find this and more technical information within the Magazine chapter Workshop informationFor additional questions please contact your local repair help desk

        244 Practical Service Precautions

        bull It makes sense to avoid exposure to electrical shock While some sources are expected to have a possible dangerous impact others of quite high potential are of limited current and are sometimes held in less regard

        bull Always respect voltages While some may not be dangerous in themselves they can cause unexpected reactions that are best avoided Before reaching into a powered TV set it is best to test the high voltage insulation It is easy to do and is a good service precaution

        54 ComPair

        541 Introduction

        ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products ComPair is a further development on the European DST (service remote control) which allows faster and more accurate diagnostics ComPair has three big advantagesbull ComPair helps you to quickly get an understanding on how

        to repair the chassis in a short time by guiding you systematically through the repair procedures

        bull ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas You do not have to know anything about I2C commands yourself because ComPair takes care of this

        bull ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available When ComPair is installed together with the SearchMan electronic manual of the defective chassis schematics and PWBs are only a mouse click away

        542 Specifications

        ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product The ComPair interface box is connected to the PC via a serial or RS232 cable In this chassis the ComPair interface box and the TV communicate via a bi-directional service cable via the service

        Service Modes Error Codes and Fault Finding EN 9L032L AA 5

        connector (located on the Main panel (see figure Top view Mono Carrier in chapter 8 Alignments) The ComPair faultfinding program is able to determine the problem of the defective television ComPair can gather diagnostic information in two waysbull Automatic (by communication with the television)

        ComPair can automatically read out the contents of the entire error buffer Diagnosis is done on I2C level ComPair can access the I2C bus of the television ComPair can send and receive I2C commands to the micro controller of the television In this way it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set

        bull Manually (by asking questions to you) Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extent When this is not the case ComPair will guide you through the faultfinding tree by asking you questions (eg Does the screen give a picture Click on the correct answer YES NO) and showing you examples (eg Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope) You can answer by clicking on a link (eg text or a waveform picture) that will bring you to the next step in the faultfinding process

        By a combination of automatic diagnostics and an interactive question answer procedure ComPair will enable you to find most problems in a fast and effective way Besides fault finding ComPair provides some additional features likebull Up- or downloading of pre-setsbull Managing of pre-set listsbull Emulation of the Dealer Service Tool (DST)bull If both ComPair and SearchMan (Electronic Service

        Manual) are installed all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink Example Measure the DC-voltage on capacitor C2568 (SchematicPanel) at the Mono-carrier ndash Click on the Panel hyperlink to automatically show the

        PWB with a highlighted capacitor C2568 ndash Click on the Schematic hyperlink to automatically

        show the position of the highlighted capacitor

        543 How to Connect ComPair

        1 First install the ComPair Browser software (see the Quick Reference Card for installation instructions)

        2 Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ldquoPCrdquo) of the ComPair interface

        3 Connect the AC power adapter to the supply connector (marked with ldquoPOWER 9V DCrdquo) on the ComPair interface

        4 Switch the ComPair interface OFF5 Switch the television set OFF (remove the AC power)6 Connect the ComPair interface cable between the

        connector on the rear side of the ComPair interface (marked with ldquoI2Crdquo) and the ComPair connector on the mono carrier (see figure Top view Mono Carrier in chapter 8 Alignments)

        7 Plug the AC power adapter in the AC power outlet and switch on the interface The green and red LEDs light up together The red LED extinguishes after approx 1 second while the green LED remains lit

        8 Start the ComPair program and read the ldquointroductionrdquo chapter

        545 Error Buffer

        The error code buffer contains all detected errors since the last time the buffer was erased The buffer is written from left to right When an error occurs that is not yet in the error code buffer it is written at the left side and all other errors shift one position to the right

        546 How To Read the Error Buffer

        You can read the error buffer in 3 waysbull On screen via the SDAM (only if you have a picture)

        Examplesndash ERROR 0 0 0 0 0 No errors detectedndash ERROR 6 0 0 0 0 Error code 6 is the last and only

        detected errorndash ERROR 9 6 0 0 0 Error code 6 was first detected and

        error code 9 is the last detected (newest) errorbull Via the blinking LED procedure (when you have no

        picture) See next paragraphbull Via ComPair

        547 How to Clear the Error Buffer

        The error code buffer is cleared in the following casesbull By activation of the CLEAR command in the SDAM menubull If the content of the error buffer has not changed for 50

        hours it resets automatically

        NoteWhen leaving SDAM by disconnecting the set from AC power the error buffer is not reset

        Service Modes Error Codes and Fault FindingEN 10 L032L AA5

        55 Error Codes

        In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)

        Table 5-3 Error Code Table

        56 The Blinking LED Procedure

        Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence

        finishes with a LED blink of 3 sbull The sequence starts again

        Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again

        57 Protections

        If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of

        the set in a predefined way and adjustment of the set via a menu and with the help of test patterns

        58 Repair Tips

        Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain

        Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective

        bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged

        bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496

        bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions

        bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

        83 Software Alignments and Settings

        The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

        831 OPTIONS

        Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

        How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

        1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

        2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

        3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

        4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

        5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

        6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

        press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

        8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

        button on the remote control transmitter or the local keyboard

        ndash Disconnect the television set from AC power for at least ten seconds

        ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

        button on the remote control transmitter or the local keyboard

        Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

        How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

        enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

        value (see first column value between brackets in table below) When an option bit is disabled its value is 0

        3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

        Figure 8-3 Option Byte calculation

        bull For a good understanding of the following circuit descriptions please use the block diagram in chapter 6 andor the electrical diagrams in chapter 7 Where necessary you will find a separate drawing for clarification

        91 Introduction

        The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

        The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

        92 Source Selection

        The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

        done entirely by the UOC and will only be able to select one external audio source

        bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

        921 Switching Function for Stereo IO

        Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

        922 Switching Function for Mono IO

        For the Mono configuration only one input pin is available for the UOC

        Video Source SelectionThe video switching is similar to the section above

        Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

        93 Audio

        This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

        931 Processing

        This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

        932 Amplifier

        The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

        Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9

        The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

        933 AVL (Automatic Volume Limiting)

        The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

        971 Introduction

        The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

        972 Derived Voltages

        The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

        98 Control

        The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

        981 I2C-Bus

        The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

        982 User Interface

        The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

        983 IO Selection

        For the control of the input and output selections there are three lines

        STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

        STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

        SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

        984 Power Supply Control

        The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

        STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

        This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

        Figure 9-2 Block diagram of power supply interface with UOC

        PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

        985 Protection Events

        Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

        Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

        I2C protectionTo check whether all I2C ICs are functioning

          242 Schematic Notes

          bull All resistor values are in ohms and the value multiplier is often used to indicate the decimal point location (eg 2K2 indicates 22 kohm)

          bull Resistor values with no multiplier may be indicated with either an E or an R (eg 220E or 220R indicates 220 ohm)

          bull All capacitor values are given in micro-farads (micro= x10-6) nano-farads (n= x10-9) or pico-farads (p= x10-12)

          bull Capacitor values may also use the value multiplier as the decimal point indication (eg 2p2 indicates 22 pF)

          bull An asterisk () indicates component usage varies Refer to the diversity tables for the correct values

          bull The correct component values are listed in the Spare Parts List Therefore always check this list when there is any doubt

          243 Lead Free Solder

          Philips CE is going to produce lead-free sets (PBF) from 112005 onwards

          Figure 2-2 Lead-free logo

          This sign normally has a diameter of 6 mm but if there is less space on a board also 3 mm is possible Regardless of this logo (is not always present) one must treat all sets from this date onwards according to the following rules

          Due to lead-free technology some rules have to be respected by the workshop during a repairbull Use only lead-free soldering tin Philips SAC305 with order

          code 0622 149 00106 If lead-free solder paste is required please contact the manufacturer of your soldering equipment In general use of solder paste within workshops should be avoided because paste is not easy to store and to handle

          bull Use only adequate solder tools applicable for lead-free soldering tin The solder tool must be able

          ndash To reach at least a solder-tip temperature of 400degCndash To stabilise the adjusted temperature at the solder-tipndash To exchange solder-tips for different applications

          bull Adjust your solder tool so that a temperature around 360degC - 380degC is reached and stabilised at the solder joint Heating time of the solder-joint should not exceed ~ 4 sec Avoid temperatures above 400degC otherwise wear-out of tips will rise drastically and flux-fluid will be destroyed To avoid wear-out of tips switch ldquooffrdquo unused equipment or reduce heat

          bull Mix of lead-free soldering tinparts with leaded soldering tinparts is possible but PHILIPS recommends strongly to avoid mixed regimes If not to avoid clean carefully the solder-joint from old tin and re-solder with new tin

          bull Use only original spare-parts listed in the Service-Manuals Not listed standard material (commodities) has to be purchased at external companies

          bull For sets produced before 112005 containing leaded soldering tin and components all needed spare parts will be available till the end of the service period For the repair of such sets nothing changes

          In case of doubt whether the board is lead-free or not (or with mixed technologies) you can use the following methodbull Always use the highest temperature to solder when using

          SAC305 (see also instructions below)bull De-solder thoroughly (clean solder joints to avoid mix of

          two alloys)Caution For BGA-ICs you must use the correct temperature-profile which is coupled to the 12NC For an overview of these profiles visit the website wwwatyourservicecephilipscom (needs subscription but is not available for all regions)You will find this and more technical information within the Magazine chapter Workshop informationFor additional questions please contact your local repair help desk

          244 Practical Service Precautions

          bull It makes sense to avoid exposure to electrical shock While some sources are expected to have a possible dangerous impact others of quite high potential are of limited current and are sometimes held in less regard

          bull Always respect voltages While some may not be dangerous in themselves they can cause unexpected reactions that are best avoided Before reaching into a powered TV set it is best to test the high voltage insulation It is easy to do and is a good service precaution

          54 ComPair

          541 Introduction

          ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products ComPair is a further development on the European DST (service remote control) which allows faster and more accurate diagnostics ComPair has three big advantagesbull ComPair helps you to quickly get an understanding on how

          to repair the chassis in a short time by guiding you systematically through the repair procedures

          bull ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas You do not have to know anything about I2C commands yourself because ComPair takes care of this

          bull ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available When ComPair is installed together with the SearchMan electronic manual of the defective chassis schematics and PWBs are only a mouse click away

          542 Specifications

          ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product The ComPair interface box is connected to the PC via a serial or RS232 cable In this chassis the ComPair interface box and the TV communicate via a bi-directional service cable via the service

          Service Modes Error Codes and Fault Finding EN 9L032L AA 5

          connector (located on the Main panel (see figure Top view Mono Carrier in chapter 8 Alignments) The ComPair faultfinding program is able to determine the problem of the defective television ComPair can gather diagnostic information in two waysbull Automatic (by communication with the television)

          ComPair can automatically read out the contents of the entire error buffer Diagnosis is done on I2C level ComPair can access the I2C bus of the television ComPair can send and receive I2C commands to the micro controller of the television In this way it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set

          bull Manually (by asking questions to you) Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extent When this is not the case ComPair will guide you through the faultfinding tree by asking you questions (eg Does the screen give a picture Click on the correct answer YES NO) and showing you examples (eg Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope) You can answer by clicking on a link (eg text or a waveform picture) that will bring you to the next step in the faultfinding process

          By a combination of automatic diagnostics and an interactive question answer procedure ComPair will enable you to find most problems in a fast and effective way Besides fault finding ComPair provides some additional features likebull Up- or downloading of pre-setsbull Managing of pre-set listsbull Emulation of the Dealer Service Tool (DST)bull If both ComPair and SearchMan (Electronic Service

          Manual) are installed all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink Example Measure the DC-voltage on capacitor C2568 (SchematicPanel) at the Mono-carrier ndash Click on the Panel hyperlink to automatically show the

          PWB with a highlighted capacitor C2568 ndash Click on the Schematic hyperlink to automatically

          show the position of the highlighted capacitor

          543 How to Connect ComPair

          1 First install the ComPair Browser software (see the Quick Reference Card for installation instructions)

          2 Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ldquoPCrdquo) of the ComPair interface

          3 Connect the AC power adapter to the supply connector (marked with ldquoPOWER 9V DCrdquo) on the ComPair interface

          4 Switch the ComPair interface OFF5 Switch the television set OFF (remove the AC power)6 Connect the ComPair interface cable between the

          connector on the rear side of the ComPair interface (marked with ldquoI2Crdquo) and the ComPair connector on the mono carrier (see figure Top view Mono Carrier in chapter 8 Alignments)

          7 Plug the AC power adapter in the AC power outlet and switch on the interface The green and red LEDs light up together The red LED extinguishes after approx 1 second while the green LED remains lit

          545 Error Buffer

          The error code buffer contains all detected errors since the last time the buffer was erased The buffer is written from left to right When an error occurs that is not yet in the error code buffer it is written at the left side and all other errors shift one position to the right

          546 How To Read the Error Buffer

          You can read the error buffer in 3 waysbull On screen via the SDAM (only if you have a picture)

          Examplesndash ERROR 0 0 0 0 0 No errors detectedndash ERROR 6 0 0 0 0 Error code 6 is the last and only

          detected errorndash ERROR 9 6 0 0 0 Error code 6 was first detected and

          error code 9 is the last detected (newest) errorbull Via the blinking LED procedure (when you have no

          picture) See next paragraphbull Via ComPair

          547 How to Clear the Error Buffer

          The error code buffer is cleared in the following casesbull By activation of the CLEAR command in the SDAM menubull If the content of the error buffer has not changed for 50

          hours it resets automatically

          NoteWhen leaving SDAM by disconnecting the set from AC power the error buffer is not reset

          Service Modes Error Codes and Fault FindingEN 10 L032L AA5

          55 Error Codes

          In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)

          Table 5-3 Error Code Table

          56 The Blinking LED Procedure

          Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence

          finishes with a LED blink of 3 sbull The sequence starts again

          Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again

          57 Protections

          If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of

          the set in a predefined way and adjustment of the set via a menu and with the help of test patterns

          58 Repair Tips

          Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain

          Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective

          bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged

          bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496

          bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions

          bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

          83 Software Alignments and Settings

          The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

          831 OPTIONS

          Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

          How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

          1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

          2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

          3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

          4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

          5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

          6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

          press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

          8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

          button on the remote control transmitter or the local keyboard

          ndash Disconnect the television set from AC power for at least ten seconds

          ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

          button on the remote control transmitter or the local keyboard

          Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

          How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

          enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

          value (see first column value between brackets in table below) When an option bit is disabled its value is 0

          3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

          bull For a good understanding of the following circuit descriptions please use the block diagram in chapter 6 andor the electrical diagrams in chapter 7 Where necessary you will find a separate drawing for clarification

          91 Introduction

          The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

          The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

          92 Source Selection

          The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

          done entirely by the UOC and will only be able to select one external audio source

          bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

          921 Switching Function for Stereo IO

          Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

          922 Switching Function for Mono IO

          For the Mono configuration only one input pin is available for the UOC

          Video Source SelectionThe video switching is similar to the section above

          Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

          93 Audio

          This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

          931 Processing

          This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

          932 Amplifier

          The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

          Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9

          The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

          933 AVL (Automatic Volume Limiting)

          The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

          Figure 9-1 AVL timing diagram

          934 Mute

          The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV

          AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed

          bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all

          initialization processes are finishedbull When the set is going to STANDBY MUTE must be

          activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier

          mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC

          TDA9853H3 Above conditions refers to both mono and stereo sets

          94 Video

          For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder

          95 Synchronization

          Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized

          with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information

          96 Deflection

          For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)

          97 Power Supply

          For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable

          971 Introduction

          The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

          98 Control

          The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

          981 I2C-Bus

          The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

          982 User Interface

          The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

          983 IO Selection

          For the control of the input and output selections there are three lines

          STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

          STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

          SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

          984 Power Supply Control

          The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

          STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

          This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

          Figure 9-2 Block diagram of power supply interface with UOC

          PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

          985 Protection Events

          Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

          Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

            54 ComPair

            541 Introduction

            ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products ComPair is a further development on the European DST (service remote control) which allows faster and more accurate diagnostics ComPair has three big advantagesbull ComPair helps you to quickly get an understanding on how

            to repair the chassis in a short time by guiding you systematically through the repair procedures

            bull ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas You do not have to know anything about I2C commands yourself because ComPair takes care of this

            bull ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available When ComPair is installed together with the SearchMan electronic manual of the defective chassis schematics and PWBs are only a mouse click away

            542 Specifications

            ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product The ComPair interface box is connected to the PC via a serial or RS232 cable In this chassis the ComPair interface box and the TV communicate via a bi-directional service cable via the service

            Service Modes Error Codes and Fault Finding EN 9L032L AA 5

            connector (located on the Main panel (see figure Top view Mono Carrier in chapter 8 Alignments) The ComPair faultfinding program is able to determine the problem of the defective television ComPair can gather diagnostic information in two waysbull Automatic (by communication with the television)

            ComPair can automatically read out the contents of the entire error buffer Diagnosis is done on I2C level ComPair can access the I2C bus of the television ComPair can send and receive I2C commands to the micro controller of the television In this way it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set

            bull Manually (by asking questions to you) Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extent When this is not the case ComPair will guide you through the faultfinding tree by asking you questions (eg Does the screen give a picture Click on the correct answer YES NO) and showing you examples (eg Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope) You can answer by clicking on a link (eg text or a waveform picture) that will bring you to the next step in the faultfinding process

            By a combination of automatic diagnostics and an interactive question answer procedure ComPair will enable you to find most problems in a fast and effective way Besides fault finding ComPair provides some additional features likebull Up- or downloading of pre-setsbull Managing of pre-set listsbull Emulation of the Dealer Service Tool (DST)bull If both ComPair and SearchMan (Electronic Service

            Manual) are installed all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink Example Measure the DC-voltage on capacitor C2568 (SchematicPanel) at the Mono-carrier ndash Click on the Panel hyperlink to automatically show the

            PWB with a highlighted capacitor C2568 ndash Click on the Schematic hyperlink to automatically

            show the position of the highlighted capacitor

            543 How to Connect ComPair

            1 First install the ComPair Browser software (see the Quick Reference Card for installation instructions)

            2 Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ldquoPCrdquo) of the ComPair interface

            3 Connect the AC power adapter to the supply connector (marked with ldquoPOWER 9V DCrdquo) on the ComPair interface

            4 Switch the ComPair interface OFF5 Switch the television set OFF (remove the AC power)6 Connect the ComPair interface cable between the

            connector on the rear side of the ComPair interface (marked with ldquoI2Crdquo) and the ComPair connector on the mono carrier (see figure Top view Mono Carrier in chapter 8 Alignments)

            7 Plug the AC power adapter in the AC power outlet and switch on the interface The green and red LEDs light up together The red LED extinguishes after approx 1 second while the green LED remains lit

            545 Error Buffer

            The error code buffer contains all detected errors since the last time the buffer was erased The buffer is written from left to right When an error occurs that is not yet in the error code buffer it is written at the left side and all other errors shift one position to the right

            546 How To Read the Error Buffer

            You can read the error buffer in 3 waysbull On screen via the SDAM (only if you have a picture)

            Examplesndash ERROR 0 0 0 0 0 No errors detectedndash ERROR 6 0 0 0 0 Error code 6 is the last and only

            detected errorndash ERROR 9 6 0 0 0 Error code 6 was first detected and

            error code 9 is the last detected (newest) errorbull Via the blinking LED procedure (when you have no

            picture) See next paragraphbull Via ComPair

            547 How to Clear the Error Buffer

            The error code buffer is cleared in the following casesbull By activation of the CLEAR command in the SDAM menubull If the content of the error buffer has not changed for 50

            hours it resets automatically

            NoteWhen leaving SDAM by disconnecting the set from AC power the error buffer is not reset

            55 Error Codes

            In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)

            Table 5-3 Error Code Table

            56 The Blinking LED Procedure

            Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence

            finishes with a LED blink of 3 sbull The sequence starts again

            Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again

            57 Protections

            If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of

            the set in a predefined way and adjustment of the set via a menu and with the help of test patterns

            58 Repair Tips

            Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain

            Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective

            bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged

            bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496

            bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions

            bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

            83 Software Alignments and Settings

            The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

            831 OPTIONS

            Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

            How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

            1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

            2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

            3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

            4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

            5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

            6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

            press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

            8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

            button on the remote control transmitter or the local keyboard

            ndash Disconnect the television set from AC power for at least ten seconds

            ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

            button on the remote control transmitter or the local keyboard

            Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

            How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

            enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

            value (see first column value between brackets in table below) When an option bit is disabled its value is 0

            3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

            bull For a good understanding of the following circuit descriptions please use the block diagram in chapter 6 andor the electrical diagrams in chapter 7 Where necessary you will find a separate drawing for clarification

            91 Introduction

            The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

            The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

            92 Source Selection

            The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

            done entirely by the UOC and will only be able to select one external audio source

            bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

            921 Switching Function for Stereo IO

            Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

            922 Switching Function for Mono IO

            For the Mono configuration only one input pin is available for the UOC

            Video Source SelectionThe video switching is similar to the section above

            Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

            93 Audio

            This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

            931 Processing

            This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

            932 Amplifier

            The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

            Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9

            The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

            933 AVL (Automatic Volume Limiting)

            The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

            Figure 9-1 AVL timing diagram

            934 Mute

            The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV

            AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed

            bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all

            initialization processes are finishedbull When the set is going to STANDBY MUTE must be

            activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier

            971 Introduction

            The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

            972 Derived Voltages

            The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

            98 Control

            The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

            981 I2C-Bus

            The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

            982 User Interface

            The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

            983 IO Selection

            For the control of the input and output selections there are three lines

            STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

            STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

            SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

            984 Power Supply Control

            The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

            STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

            This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

            Figure 9-2 Block diagram of power supply interface with UOC

            PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

            985 Protection Events

            Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

            Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

              54 ComPair

              541 Introduction

              ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products ComPair is a further development on the European DST (service remote control) which allows faster and more accurate diagnostics ComPair has three big advantagesbull ComPair helps you to quickly get an understanding on how

              to repair the chassis in a short time by guiding you systematically through the repair procedures

              bull ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas You do not have to know anything about I2C commands yourself because ComPair takes care of this

              bull ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available When ComPair is installed together with the SearchMan electronic manual of the defective chassis schematics and PWBs are only a mouse click away

              542 Specifications

              ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product The ComPair interface box is connected to the PC via a serial or RS232 cable In this chassis the ComPair interface box and the TV communicate via a bi-directional service cable via the service

              Service Modes Error Codes and Fault Finding EN 9L032L AA 5

              connector (located on the Main panel (see figure Top view Mono Carrier in chapter 8 Alignments) The ComPair faultfinding program is able to determine the problem of the defective television ComPair can gather diagnostic information in two waysbull Automatic (by communication with the television)

              ComPair can automatically read out the contents of the entire error buffer Diagnosis is done on I2C level ComPair can access the I2C bus of the television ComPair can send and receive I2C commands to the micro controller of the television In this way it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set

              bull Manually (by asking questions to you) Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extent When this is not the case ComPair will guide you through the faultfinding tree by asking you questions (eg Does the screen give a picture Click on the correct answer YES NO) and showing you examples (eg Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope) You can answer by clicking on a link (eg text or a waveform picture) that will bring you to the next step in the faultfinding process

              By a combination of automatic diagnostics and an interactive question answer procedure ComPair will enable you to find most problems in a fast and effective way Besides fault finding ComPair provides some additional features likebull Up- or downloading of pre-setsbull Managing of pre-set listsbull Emulation of the Dealer Service Tool (DST)bull If both ComPair and SearchMan (Electronic Service

              Manual) are installed all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink Example Measure the DC-voltage on capacitor C2568 (SchematicPanel) at the Mono-carrier ndash Click on the Panel hyperlink to automatically show the

              PWB with a highlighted capacitor C2568 ndash Click on the Schematic hyperlink to automatically

              show the position of the highlighted capacitor

              543 How to Connect ComPair

              1 First install the ComPair Browser software (see the Quick Reference Card for installation instructions)

              2 Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ldquoPCrdquo) of the ComPair interface

              3 Connect the AC power adapter to the supply connector (marked with ldquoPOWER 9V DCrdquo) on the ComPair interface

              4 Switch the ComPair interface OFF5 Switch the television set OFF (remove the AC power)6 Connect the ComPair interface cable between the

              connector on the rear side of the ComPair interface (marked with ldquoI2Crdquo) and the ComPair connector on the mono carrier (see figure Top view Mono Carrier in chapter 8 Alignments)

              7 Plug the AC power adapter in the AC power outlet and switch on the interface The green and red LEDs light up together The red LED extinguishes after approx 1 second while the green LED remains lit

              545 Error Buffer

              The error code buffer contains all detected errors since the last time the buffer was erased The buffer is written from left to right When an error occurs that is not yet in the error code buffer it is written at the left side and all other errors shift one position to the right

              546 How To Read the Error Buffer

              You can read the error buffer in 3 waysbull On screen via the SDAM (only if you have a picture)

              Examplesndash ERROR 0 0 0 0 0 No errors detectedndash ERROR 6 0 0 0 0 Error code 6 is the last and only

              detected errorndash ERROR 9 6 0 0 0 Error code 6 was first detected and

              error code 9 is the last detected (newest) errorbull Via the blinking LED procedure (when you have no

              picture) See next paragraphbull Via ComPair

              547 How to Clear the Error Buffer

              The error code buffer is cleared in the following casesbull By activation of the CLEAR command in the SDAM menubull If the content of the error buffer has not changed for 50

              hours it resets automatically

              NoteWhen leaving SDAM by disconnecting the set from AC power the error buffer is not reset

              55 Error Codes

              In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)

              Table 5-3 Error Code Table

              56 The Blinking LED Procedure

              Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence

              finishes with a LED blink of 3 sbull The sequence starts again

              Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again

              57 Protections

              If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of

              the set in a predefined way and adjustment of the set via a menu and with the help of test patterns

              58 Repair Tips

              Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain

              Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective

              bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged

              bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496

              bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions

              bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

              83 Software Alignments and Settings

              The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

              831 OPTIONS

              Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

              How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

              1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

              2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

              3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

              4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

              5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

              6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

              press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

              8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

              button on the remote control transmitter or the local keyboard

              ndash Disconnect the television set from AC power for at least ten seconds

              ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

              button on the remote control transmitter or the local keyboard

              Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

              How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

              enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

              value (see first column value between brackets in table below) When an option bit is disabled its value is 0

              3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

              91 Introduction

              The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

              The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

              92 Source Selection

              The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

              done entirely by the UOC and will only be able to select one external audio source

              bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

              921 Switching Function for Stereo IO

              Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

              922 Switching Function for Mono IO

              For the Mono configuration only one input pin is available for the UOC

              Video Source SelectionThe video switching is similar to the section above

              Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

              93 Audio

              This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

              931 Processing

              This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

              932 Amplifier

              The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

              Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9

              The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

              933 AVL (Automatic Volume Limiting)

              The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

              Figure 9-1 AVL timing diagram

              934 Mute

              The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV

              AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed

              bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all

              initialization processes are finishedbull When the set is going to STANDBY MUTE must be

              activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier

              mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC

              TDA9853H3 Above conditions refers to both mono and stereo sets

              For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder

              95 Synchronization

              Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized

              with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information

              96 Deflection

              For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)

              The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

              972 Derived Voltages

              98 Control

              The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

              981 I2C-Bus

              The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

              982 User Interface

              The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

              983 IO Selection

              For the control of the input and output selections there are three lines

              STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

              STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

              SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

              984 Power Supply Control

              The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

              STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

              This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

              Figure 9-2 Block diagram of power supply interface with UOC

              PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

              985 Protection Events

              Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

              Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

              I2C protectionTo check whether all I2C ICs are functioning

                541 Introduction

                ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products ComPair is a further development on the European DST (service remote control) which allows faster and more accurate diagnostics ComPair has three big advantagesbull ComPair helps you to quickly get an understanding on how

                to repair the chassis in a short time by guiding you systematically through the repair procedures

                bull ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas You do not have to know anything about I2C commands yourself because ComPair takes care of this

                bull ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available When ComPair is installed together with the SearchMan electronic manual of the defective chassis schematics and PWBs are only a mouse click away

                542 Specifications

                ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product The ComPair interface box is connected to the PC via a serial or RS232 cable In this chassis the ComPair interface box and the TV communicate via a bi-directional service cable via the service

                Service Modes Error Codes and Fault Finding EN 9L032L AA 5

                connector (located on the Main panel (see figure Top view Mono Carrier in chapter 8 Alignments) The ComPair faultfinding program is able to determine the problem of the defective television ComPair can gather diagnostic information in two waysbull Automatic (by communication with the television)

                ComPair can automatically read out the contents of the entire error buffer Diagnosis is done on I2C level ComPair can access the I2C bus of the television ComPair can send and receive I2C commands to the micro controller of the television In this way it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set

                bull Manually (by asking questions to you) Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extent When this is not the case ComPair will guide you through the faultfinding tree by asking you questions (eg Does the screen give a picture Click on the correct answer YES NO) and showing you examples (eg Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope) You can answer by clicking on a link (eg text or a waveform picture) that will bring you to the next step in the faultfinding process

                By a combination of automatic diagnostics and an interactive question answer procedure ComPair will enable you to find most problems in a fast and effective way Besides fault finding ComPair provides some additional features likebull Up- or downloading of pre-setsbull Managing of pre-set listsbull Emulation of the Dealer Service Tool (DST)bull If both ComPair and SearchMan (Electronic Service

                Manual) are installed all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink Example Measure the DC-voltage on capacitor C2568 (SchematicPanel) at the Mono-carrier ndash Click on the Panel hyperlink to automatically show the

                PWB with a highlighted capacitor C2568 ndash Click on the Schematic hyperlink to automatically

                show the position of the highlighted capacitor

                543 How to Connect ComPair

                1 First install the ComPair Browser software (see the Quick Reference Card for installation instructions)

                2 Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ldquoPCrdquo) of the ComPair interface

                3 Connect the AC power adapter to the supply connector (marked with ldquoPOWER 9V DCrdquo) on the ComPair interface

                4 Switch the ComPair interface OFF5 Switch the television set OFF (remove the AC power)6 Connect the ComPair interface cable between the

                connector on the rear side of the ComPair interface (marked with ldquoI2Crdquo) and the ComPair connector on the mono carrier (see figure Top view Mono Carrier in chapter 8 Alignments)

                7 Plug the AC power adapter in the AC power outlet and switch on the interface The green and red LEDs light up together The red LED extinguishes after approx 1 second while the green LED remains lit

                8 Start the ComPair program and read the ldquointroductionrdquo chapter

                545 Error Buffer

                The error code buffer contains all detected errors since the last time the buffer was erased The buffer is written from left to right When an error occurs that is not yet in the error code buffer it is written at the left side and all other errors shift one position to the right

                546 How To Read the Error Buffer

                You can read the error buffer in 3 waysbull On screen via the SDAM (only if you have a picture)

                Examplesndash ERROR 0 0 0 0 0 No errors detectedndash ERROR 6 0 0 0 0 Error code 6 is the last and only

                detected errorndash ERROR 9 6 0 0 0 Error code 6 was first detected and

                error code 9 is the last detected (newest) errorbull Via the blinking LED procedure (when you have no

                picture) See next paragraphbull Via ComPair

                547 How to Clear the Error Buffer

                The error code buffer is cleared in the following casesbull By activation of the CLEAR command in the SDAM menubull If the content of the error buffer has not changed for 50

                hours it resets automatically

                NoteWhen leaving SDAM by disconnecting the set from AC power the error buffer is not reset

                55 Error Codes

                In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)

                Table 5-3 Error Code Table

                56 The Blinking LED Procedure

                Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence

                finishes with a LED blink of 3 sbull The sequence starts again

                Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again

                57 Protections

                If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of

                the set in a predefined way and adjustment of the set via a menu and with the help of test patterns

                58 Repair Tips

                Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain

                Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective

                bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged

                bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496

                bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions

                bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

                The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

                831 OPTIONS

                Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

                3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

                4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

                5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

                6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

                press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

                8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

                button on the remote control transmitter or the local keyboard

                ndash Disconnect the television set from AC power for at least ten seconds

                ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

                button on the remote control transmitter or the local keyboard

                Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                Figure 8-3 Option Byte calculation

                91 Introduction

                The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                92 Source Selection

                The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                done entirely by the UOC and will only be able to select one external audio source

                bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                921 Switching Function for Stereo IO

                Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                922 Switching Function for Mono IO

                For the Mono configuration only one input pin is available for the UOC

                Video Source SelectionThe video switching is similar to the section above

                Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                93 Audio

                This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                931 Processing

                This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                932 Amplifier

                The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9

                The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                933 AVL (Automatic Volume Limiting)

                The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                Figure 9-1 AVL timing diagram

                934 Mute

                The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV

                AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed

                bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all

                initialization processes are finishedbull When the set is going to STANDBY MUTE must be

                activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier

                mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC

                TDA9853H3 Above conditions refers to both mono and stereo sets

                94 Video

                For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder

                95 Synchronization

                Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized

                with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information

                96 Deflection

                For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)

                97 Power Supply

                For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable

                971 Introduction

                The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                98 Control

                The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                981 I2C-Bus

                The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                982 User Interface

                The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                983 IO Selection

                For the control of the input and output selections there are three lines

                STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                984 Power Supply Control

                The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                Figure 9-2 Block diagram of power supply interface with UOC

                PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                985 Protection Events

                Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                  connector (located on the Main panel (see figure Top view Mono Carrier in chapter 8 Alignments) The ComPair faultfinding program is able to determine the problem of the defective television ComPair can gather diagnostic information in two waysbull Automatic (by communication with the television)

                  ComPair can automatically read out the contents of the entire error buffer Diagnosis is done on I2C level ComPair can access the I2C bus of the television ComPair can send and receive I2C commands to the micro controller of the television In this way it is possible for ComPair to communicate (read and write) to devices on the I2C busses of the TV-set

                  bull Manually (by asking questions to you) Automatic diagnosis is only possible if the micro controller of the television is working correctly and only to a certain extent When this is not the case ComPair will guide you through the faultfinding tree by asking you questions (eg Does the screen give a picture Click on the correct answer YES NO) and showing you examples (eg Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope) You can answer by clicking on a link (eg text or a waveform picture) that will bring you to the next step in the faultfinding process

                  By a combination of automatic diagnostics and an interactive question answer procedure ComPair will enable you to find most problems in a fast and effective way Besides fault finding ComPair provides some additional features likebull Up- or downloading of pre-setsbull Managing of pre-set listsbull Emulation of the Dealer Service Tool (DST)bull If both ComPair and SearchMan (Electronic Service

                  Manual) are installed all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink Example Measure the DC-voltage on capacitor C2568 (SchematicPanel) at the Mono-carrier ndash Click on the Panel hyperlink to automatically show the

                  PWB with a highlighted capacitor C2568 ndash Click on the Schematic hyperlink to automatically

                  show the position of the highlighted capacitor

                  543 How to Connect ComPair

                  1 First install the ComPair Browser software (see the Quick Reference Card for installation instructions)

                  2 Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with ldquoPCrdquo) of the ComPair interface

                  3 Connect the AC power adapter to the supply connector (marked with ldquoPOWER 9V DCrdquo) on the ComPair interface

                  4 Switch the ComPair interface OFF5 Switch the television set OFF (remove the AC power)6 Connect the ComPair interface cable between the

                  connector on the rear side of the ComPair interface (marked with ldquoI2Crdquo) and the ComPair connector on the mono carrier (see figure Top view Mono Carrier in chapter 8 Alignments)

                  7 Plug the AC power adapter in the AC power outlet and switch on the interface The green and red LEDs light up together The red LED extinguishes after approx 1 second while the green LED remains lit

                  545 Error Buffer

                  The error code buffer contains all detected errors since the last time the buffer was erased The buffer is written from left to right When an error occurs that is not yet in the error code buffer it is written at the left side and all other errors shift one position to the right

                  546 How To Read the Error Buffer

                  You can read the error buffer in 3 waysbull On screen via the SDAM (only if you have a picture)

                  Examplesndash ERROR 0 0 0 0 0 No errors detectedndash ERROR 6 0 0 0 0 Error code 6 is the last and only

                  detected errorndash ERROR 9 6 0 0 0 Error code 6 was first detected and

                  error code 9 is the last detected (newest) errorbull Via the blinking LED procedure (when you have no

                  picture) See next paragraphbull Via ComPair

                  547 How to Clear the Error Buffer

                  The error code buffer is cleared in the following casesbull By activation of the CLEAR command in the SDAM menubull If the content of the error buffer has not changed for 50

                  hours it resets automatically

                  NoteWhen leaving SDAM by disconnecting the set from AC power the error buffer is not reset

                  55 Error Codes

                  In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)

                  Table 5-3 Error Code Table

                  56 The Blinking LED Procedure

                  Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence

                  finishes with a LED blink of 3 sbull The sequence starts again

                  Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again

                  57 Protections

                  If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of

                  the set in a predefined way and adjustment of the set via a menu and with the help of test patterns

                  58 Repair Tips

                  Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain

                  Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective

                  bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged

                  bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496

                  bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions

                  bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

                  83 Software Alignments and Settings

                  The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

                  831 OPTIONS

                  Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                  How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                  1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                  2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

                  3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

                  4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

                  5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

                  6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

                  press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

                  8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

                  button on the remote control transmitter or the local keyboard

                  ndash Disconnect the television set from AC power for at least ten seconds

                  ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

                  button on the remote control transmitter or the local keyboard

                  Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                  How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                  enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                  value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                  3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                  91 Introduction

                  The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                  The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                  92 Source Selection

                  The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                  done entirely by the UOC and will only be able to select one external audio source

                  bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                  921 Switching Function for Stereo IO

                  Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                  922 Switching Function for Mono IO

                  For the Mono configuration only one input pin is available for the UOC

                  Video Source SelectionThe video switching is similar to the section above

                  Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                  93 Audio

                  This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                  931 Processing

                  This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                  932 Amplifier

                  The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                  Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9

                  The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                  933 AVL (Automatic Volume Limiting)

                  The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                  Figure 9-1 AVL timing diagram

                  934 Mute

                  The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV

                  AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed

                  bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all

                  initialization processes are finishedbull When the set is going to STANDBY MUTE must be

                  activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier

                  mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC

                  95 Synchronization

                  Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized

                  with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information

                  96 Deflection

                  For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)

                  97 Power Supply

                  For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable

                  971 Introduction

                  The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                  972 Derived Voltages

                  The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

                  98 Control

                  The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                  981 I2C-Bus

                  The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                  982 User Interface

                  The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                  983 IO Selection

                  For the control of the input and output selections there are three lines

                  STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                  STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                  SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                  984 Power Supply Control

                  The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                  STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                  This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                  Figure 9-2 Block diagram of power supply interface with UOC

                  PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                  985 Protection Events

                  Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                  Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                    Service Modes Error Codes and Fault FindingEN 10 L032L AA5

                    55 Error Codes

                    In case of non-intermittent faults clear the error buffer before you begin the repair These to ensure that old error codes are no longer present If possible check the entire contents of the error buffer In some situations an error code is only the result of another error code and not the actual cause (eg a fault in the protection detection circuitry can also lead to a protection)

                    Table 5-3 Error Code Table

                    56 The Blinking LED Procedure

                    Via this procedure you can make the contents of the error buffer visible via the front LED This is especially useful when there is no picture When the SDAM is entered the LED will blink the contents of the error-buffer bull n short blinks (n = 1 - 14)bull When all the error-codes are displayed the sequence

                    finishes with a LED blink of 3 sbull The sequence starts again

                    Example of error buffer 12 9 6 0 0 After entering SDAM bull 12 short blinks followed by a pause of 3 sbull 9 short blinks followed by a pause of 3 sbull 6 short blinks followed by a pause of 3 sbull 1 long blink of 3 s to finish the sequencebull the sequence starts again

                    57 Protections

                    If a fault situation is detected an error code will be generated and if necessary the set will be put in the protection mode Blinking of the red LED at a frequency of 3 Hz indicates the protection mode In some error cases the microprocessor does not put the set in the protection mode The error codes of the error buffer can be read via the service menu (SDAM) the blinking LED procedure or via ComPair To get a quick diagnosis the chassis has one service modes implementedbull The Service Default Alignment Mode (SDAM) Start-up of

                    the set in a predefined way and adjustment of the set via a menu and with the help of test patterns

                    58 Repair Tips

                    Below some failure symptoms are given followed by a repair tipbull Set is dead and makes hiccupping sound ldquoMain

                    Supplyrdquo is available Hiccupping stops when de-soldering L5563 meaning that problem is in the ldquoMain Supplyrdquo line No output voltages at LOT no horizontal deflection Reason line transistor 7421 is defective

                    bull Set is dead and makes no sound Check power supply IC 7520 Result voltage at pins 2 6 7 9 and 11 are about 180 V and pin 14 is 0 V The reason why the voltage on these pins is so high is because the output driver (pin 11) has an open load That is why MOSFET 7521 is not able to switch Reason feedback resistor 3523 is defective Caution be careful measuring on the gate of 7521 circuitry is very high ohmic and can easily be damaged

                    bull Set is in hiccup mode and shuts down after 8 s Blinking LED (set in SDM mode) indicates error 5 As it is unlikely that the ldquoPORrdquo and ldquo+8V protectionrdquo happen at the same time measure the ldquo+8Vrdquo If this voltage is missing check transistor 7491 and 7496

                    bull Set is non-stop in hiccup mode Set is in over current mode check the secondary sensing (opto coupler 7515) and the ldquoMain Supplyrdquo voltage Signal ldquoStdby_conrdquo must be logic low under normal operation conditions and goes to high (33 V) under standby and fault conditions

                    bull Set turns on but without picture and sound The screen shows snow but OSD and other menus are okay Blinking LED procedure indicates error 11 so problem is expected in the tuner (pos 1000) Check presence of supply voltages As ldquoVlotaux+5Vrdquo at pin 5 and 7 are okay ldquoVT_supplyrdquo at pin 9 is missing Conclusion resistor 3449 and 3450 are defective

                    83 Software Alignments and Settings

                    The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

                    831 OPTIONS

                    Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                    How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                    1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                    2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

                    3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

                    4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

                    5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

                    6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

                    press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

                    8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

                    button on the remote control transmitter or the local keyboard

                    ndash Disconnect the television set from AC power for at least ten seconds

                    ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

                    button on the remote control transmitter or the local keyboard

                    Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                    How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                    enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                    value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                    3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                    The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                    The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                    92 Source Selection

                    The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                    done entirely by the UOC and will only be able to select one external audio source

                    bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                    921 Switching Function for Stereo IO

                    Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                    922 Switching Function for Mono IO

                    For the Mono configuration only one input pin is available for the UOC

                    Video Source SelectionThe video switching is similar to the section above

                    Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                    93 Audio

                    This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                    931 Processing

                    This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                    932 Amplifier

                    The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                    The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                    933 AVL (Automatic Volume Limiting)

                    The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                    934 Mute

                    The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV

                    AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed

                    bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all

                    initialization processes are finishedbull When the set is going to STANDBY MUTE must be

                    activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier

                    mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC

                    TDA9853H3 Above conditions refers to both mono and stereo sets

                    For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder

                    95 Synchronization

                    Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized

                    with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information

                    96 Deflection

                    For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable The L03 range consists of TV sets spanning from 14 to 21 inch using the same chassis architecture For the chassis architecture the CRTs used do not need EastWest Correction Therefore the geometry correction needed is horizontal shift vertical slope vertical amplitude vertical S-correction vertical shift and vertical zoom for geometry corrections (with the appropriate offsets required for NTSC channels on PAL sets)

                    97 Power Supply

                    For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable

                    971 Introduction

                    The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                    972 Derived Voltages

                    The voltages supplied by the secondary windings of T5520 arebull MainSupply for the horizontal outputbull VauxVaudio for the audio circuitbull An optional DVDSupply for future extensions Other voltages are provided by the LOT It supplies -12 V the tuner voltage the filament voltage and the +160 V source for the video drive These secondary voltages of the LOT are monitored by the EHT lines

                    98 Control

                    The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                    981 I2C-Bus

                    The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                    982 User Interface

                    The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                    983 IO Selection

                    For the control of the input and output selections there are three lines

                    STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                    STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                    SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                    984 Power Supply Control

                    The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                    STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                    This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                    Figure 9-2 Block diagram of power supply interface with UOC

                    PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                    985 Protection Events

                    Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                    Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                      Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                      How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                      1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                      2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

                      3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

                      4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

                      5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

                      6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

                      press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

                      8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

                      button on the remote control transmitter or the local keyboard

                      ndash Disconnect the television set from AC power for at least ten seconds

                      ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

                      button on the remote control transmitter or the local keyboard

                      Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                      How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                      enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                      value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                      3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                      Figure 8-3 Option Byte calculation

                      91 Introduction

                      The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                      The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                      92 Source Selection

                      The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                      done entirely by the UOC and will only be able to select one external audio source

                      bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                      921 Switching Function for Stereo IO

                      Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                      922 Switching Function for Mono IO

                      For the Mono configuration only one input pin is available for the UOC

                      Video Source SelectionThe video switching is similar to the section above

                      Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                      93 Audio

                      This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                      931 Processing

                      This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                      932 Amplifier

                      The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                      Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9

                      The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                      933 AVL (Automatic Volume Limiting)

                      The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                      934 Mute

                      The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV

                      AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed

                      bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all

                      initialization processes are finishedbull When the set is going to STANDBY MUTE must be

                      activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier

                      mute (= PWM volume control mute)2 The first condition does not apply for the UOC IC

                      TDA9853H3 Above conditions refers to both mono and stereo sets

                      For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder

                      95 Synchronization

                      Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized

                      971 Introduction

                      The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                      98 Control

                      The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                      981 I2C-Bus

                      The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                      982 User Interface

                      The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                      983 IO Selection

                      For the control of the input and output selections there are three lines

                      STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                      STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                      SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                      984 Power Supply Control

                      The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                      STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                      This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                      Figure 9-2 Block diagram of power supply interface with UOC

                      PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                      985 Protection Events

                      Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                      Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                        The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

                        831 OPTIONS

                        Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                        How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                        1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                        2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

                        3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

                        4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

                        5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

                        6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

                        press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

                        8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

                        button on the remote control transmitter or the local keyboard

                        ndash Disconnect the television set from AC power for at least ten seconds

                        ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

                        button on the remote control transmitter or the local keyboard

                        Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                        How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                        enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                        value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                        3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                        91 Introduction

                        The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                        The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                        done entirely by the UOC and will only be able to select one external audio source

                        bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                        921 Switching Function for Stereo IO

                        Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                        922 Switching Function for Mono IO

                        For the Mono configuration only one input pin is available for the UOC

                        Video Source SelectionThe video switching is similar to the section above

                        Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                        93 Audio

                        This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                        931 Processing

                        This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                        932 Amplifier

                        The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                        The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                        933 AVL (Automatic Volume Limiting)

                        The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                        971 Introduction

                        The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                        98 Control

                        The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                        981 I2C-Bus

                        The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                        982 User Interface

                        The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                        983 IO Selection

                        For the control of the input and output selections there are three lines

                        STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                        STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                        SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                        984 Power Supply Control

                        The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                        STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                        This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                        Figure 9-2 Block diagram of power supply interface with UOC

                        PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                        985 Protection Events

                        Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                        Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                          The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

                          831 OPTIONS

                          Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                          How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                          1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                          2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

                          3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

                          4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

                          5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

                          6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

                          press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

                          8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

                          button on the remote control transmitter or the local keyboard

                          ndash Disconnect the television set from AC power for at least ten seconds

                          ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

                          button on the remote control transmitter or the local keyboard

                          How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                          enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                          value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                          3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                          91 Introduction

                          The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                          The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                          92 Source Selection

                          The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                          done entirely by the UOC and will only be able to select one external audio source

                          bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                          921 Switching Function for Stereo IO

                          Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                          922 Switching Function for Mono IO

                          For the Mono configuration only one input pin is available for the UOC

                          Video Source SelectionThe video switching is similar to the section above

                          Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                          93 Audio

                          This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                          931 Processing

                          This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                          932 Amplifier

                          The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                          Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9

                          The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                          933 AVL (Automatic Volume Limiting)

                          The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                          971 Introduction

                          The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                          98 Control

                          The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                          981 I2C-Bus

                          The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                          982 User Interface

                          The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                          983 IO Selection

                          For the control of the input and output selections there are three lines

                          STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                          STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                          SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                          984 Power Supply Control

                          The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                          STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                          This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                          Figure 9-2 Block diagram of power supply interface with UOC

                          PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                          985 Protection Events

                          Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                          Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                            Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                            How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                            1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                            2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

                            3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

                            4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

                            5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

                            6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

                            press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

                            8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

                            button on the remote control transmitter or the local keyboard

                            ndash Disconnect the television set from AC power for at least ten seconds

                            ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

                            button on the remote control transmitter or the local keyboard

                            Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                            How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                            enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                            value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                            3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                            Figure 8-3 Option Byte calculation

                            The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                            The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                            The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                            done entirely by the UOC and will only be able to select one external audio source

                            bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                            921 Switching Function for Stereo IO

                            Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                            922 Switching Function for Mono IO

                            For the Mono configuration only one input pin is available for the UOC

                            Video Source SelectionThe video switching is similar to the section above

                            Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                            93 Audio

                            This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                            931 Processing

                            This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                            932 Amplifier

                            The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                            The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                            933 AVL (Automatic Volume Limiting)

                            The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                            initialization processes are finishedbull When the set is going to STANDBY MUTE must be

                            activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier

                            971 Introduction

                            The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                            98 Control

                            The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                            981 I2C-Bus

                            The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                            982 User Interface

                            The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                            983 IO Selection

                            For the control of the input and output selections there are three lines

                            STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                            STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                            SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                            984 Power Supply Control

                            The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                            STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                            This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                            Figure 9-2 Block diagram of power supply interface with UOC

                            PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                            985 Protection Events

                            Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                            Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                              The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

                              831 OPTIONS

                              Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                              How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                              1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                              2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

                              3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

                              4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

                              5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

                              6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

                              press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

                              8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

                              button on the remote control transmitter or the local keyboard

                              ndash Disconnect the television set from AC power for at least ten seconds

                              ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

                              button on the remote control transmitter or the local keyboard

                              Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                              How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                              enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                              91 Introduction

                              The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                              The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                              92 Source Selection

                              The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                              done entirely by the UOC and will only be able to select one external audio source

                              bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                              921 Switching Function for Stereo IO

                              Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                              922 Switching Function for Mono IO

                              For the Mono configuration only one input pin is available for the UOC

                              Video Source SelectionThe video switching is similar to the section above

                              Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                              93 Audio

                              This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                              931 Processing

                              This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                              932 Amplifier

                              The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                              The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                              933 AVL (Automatic Volume Limiting)

                              The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                              971 Introduction

                              The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                              98 Control

                              The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                              981 I2C-Bus

                              The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                              982 User Interface

                              The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                              983 IO Selection

                              For the control of the input and output selections there are three lines

                              STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                              STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                              SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                              984 Power Supply Control

                              The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                              STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                              This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                              Figure 9-2 Block diagram of power supply interface with UOC

                              PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                              985 Protection Events

                              Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                              Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                                The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

                                831 OPTIONS

                                Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                                How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                                1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                                2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

                                3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

                                4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

                                5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

                                6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

                                press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

                                8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

                                button on the remote control transmitter or the local keyboard

                                ndash Disconnect the television set from AC power for at least ten seconds

                                ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

                                button on the remote control transmitter or the local keyboard

                                Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                                How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                                enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                                value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                                3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                                91 Introduction

                                The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                92 Source Selection

                                The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                                done entirely by the UOC and will only be able to select one external audio source

                                bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                                921 Switching Function for Stereo IO

                                Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                                922 Switching Function for Mono IO

                                For the Mono configuration only one input pin is available for the UOC

                                Video Source SelectionThe video switching is similar to the section above

                                Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                                93 Audio

                                This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                                931 Processing

                                This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                                932 Amplifier

                                The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                                Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9

                                The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                                933 AVL (Automatic Volume Limiting)

                                The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                                934 Mute

                                The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV

                                AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed

                                bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all

                                initialization processes are finishedbull When the set is going to STANDBY MUTE must be

                                activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier

                                95 Synchronization

                                Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized

                                with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information

                                The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                                98 Control

                                The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                                981 I2C-Bus

                                The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                                982 User Interface

                                The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                                983 IO Selection

                                For the control of the input and output selections there are three lines

                                STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                                STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                                SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                                984 Power Supply Control

                                The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                                STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                Figure 9-2 Block diagram of power supply interface with UOC

                                PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                                985 Protection Events

                                Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                                Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                                  The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

                                  831 OPTIONS

                                  Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                                  How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                                  1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                                  2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

                                  3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

                                  4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

                                  5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

                                  6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

                                  press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

                                  8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

                                  button on the remote control transmitter or the local keyboard

                                  ndash Disconnect the television set from AC power for at least ten seconds

                                  ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

                                  button on the remote control transmitter or the local keyboard

                                  Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                                  How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                                  enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                                  value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                                  3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                                  The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                  The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                  92 Source Selection

                                  The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                                  done entirely by the UOC and will only be able to select one external audio source

                                  bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                                  921 Switching Function for Stereo IO

                                  Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                                  922 Switching Function for Mono IO

                                  For the Mono configuration only one input pin is available for the UOC

                                  Video Source SelectionThe video switching is similar to the section above

                                  Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                                  93 Audio

                                  This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                                  931 Processing

                                  This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                                  932 Amplifier

                                  The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                                  971 Introduction

                                  The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                                  98 Control

                                  The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                                  981 I2C-Bus

                                  The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                                  982 User Interface

                                  The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                                  983 IO Selection

                                  For the control of the input and output selections there are three lines

                                  STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                                  STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                                  SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                                  984 Power Supply Control

                                  The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                                  STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                  This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                  Figure 9-2 Block diagram of power supply interface with UOC

                                  PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                                  985 Protection Events

                                  Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                                  Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                                    The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

                                    831 OPTIONS

                                    Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                                    How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                                    1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                                    2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

                                    3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

                                    4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

                                    5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

                                    6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

                                    press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

                                    8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

                                    button on the remote control transmitter or the local keyboard

                                    ndash Disconnect the television set from AC power for at least ten seconds

                                    ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

                                    button on the remote control transmitter or the local keyboard

                                    Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                                    How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                                    enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                                    value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                                    3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                                    The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                    The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                    92 Source Selection

                                    The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                                    done entirely by the UOC and will only be able to select one external audio source

                                    bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                                    921 Switching Function for Stereo IO

                                    Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                                    922 Switching Function for Mono IO

                                    For the Mono configuration only one input pin is available for the UOC

                                    Video Source SelectionThe video switching is similar to the section above

                                    Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                                    93 Audio

                                    This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                                    931 Processing

                                    This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                                    932 Amplifier

                                    The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                                    The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                                    933 AVL (Automatic Volume Limiting)

                                    The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                                    The TV set must mutebull Whenever a User Mute is activatedbull Whenever there is a channel change RF to RF RF to AV

                                    AV to RF and AV to AV (if any) In channel change MUTE must be activated first before any other activity and un-MUTE must be done after every other activity has been completed

                                    bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all

                                    initialization processes are finishedbull When the set is going to STANDBY MUTE must be

                                    activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier

                                    971 Introduction

                                    The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                                    98 Control

                                    The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                                    981 I2C-Bus

                                    The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                                    982 User Interface

                                    The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                                    983 IO Selection

                                    For the control of the input and output selections there are three lines

                                    STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                                    STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                                    SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                                    984 Power Supply Control

                                    The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                                    STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                    This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                    Figure 9-2 Block diagram of power supply interface with UOC

                                    PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                                    985 Protection Events

                                    Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                                    Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                                      The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

                                      831 OPTIONS

                                      Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                                      How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                                      1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                                      2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

                                      3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

                                      4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

                                      5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

                                      6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

                                      press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

                                      8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

                                      button on the remote control transmitter or the local keyboard

                                      ndash Disconnect the television set from AC power for at least ten seconds

                                      ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

                                      button on the remote control transmitter or the local keyboard

                                      Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                                      How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                                      enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                                      value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                                      3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                                      91 Introduction

                                      The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                      The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                      92 Source Selection

                                      The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                                      done entirely by the UOC and will only be able to select one external audio source

                                      bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                                      921 Switching Function for Stereo IO

                                      Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                                      922 Switching Function for Mono IO

                                      For the Mono configuration only one input pin is available for the UOC

                                      Video Source SelectionThe video switching is similar to the section above

                                      Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                                      93 Audio

                                      This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                                      This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                                      932 Amplifier

                                      The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                                      The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                                      933 AVL (Automatic Volume Limiting)

                                      The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                                      971 Introduction

                                      The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                                      98 Control

                                      The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                                      981 I2C-Bus

                                      The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                                      982 User Interface

                                      The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                                      983 IO Selection

                                      For the control of the input and output selections there are three lines

                                      STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                                      STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                                      SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                                      984 Power Supply Control

                                      The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                                      STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                      This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                      Figure 9-2 Block diagram of power supply interface with UOC

                                      PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                                      985 Protection Events

                                      Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                                      Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                                        The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

                                        831 OPTIONS

                                        Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                                        How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                                        1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                                        2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

                                        3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

                                        4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

                                        5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

                                        6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

                                        press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

                                        8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

                                        button on the remote control transmitter or the local keyboard

                                        ndash Disconnect the television set from AC power for at least ten seconds

                                        ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

                                        button on the remote control transmitter or the local keyboard

                                        Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                                        How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                                        enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                                        value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                                        3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                                        91 Introduction

                                        The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                        The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                        92 Source Selection

                                        The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                                        done entirely by the UOC and will only be able to select one external audio source

                                        bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                                        921 Switching Function for Stereo IO

                                        Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                                        922 Switching Function for Mono IO

                                        For the Mono configuration only one input pin is available for the UOC

                                        Video Source SelectionThe video switching is similar to the section above

                                        Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                                        93 Audio

                                        This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                                        931 Processing

                                        This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                                        932 Amplifier

                                        The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                                        The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                                        933 AVL (Automatic Volume Limiting)

                                        The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                                        971 Introduction

                                        The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                                        98 Control

                                        The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                                        981 I2C-Bus

                                        The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                                        982 User Interface

                                        The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                                        983 IO Selection

                                        For the control of the input and output selections there are three lines

                                        STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                                        STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                                        SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                                        984 Power Supply Control

                                        The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                                        STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                        This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                        Figure 9-2 Block diagram of power supply interface with UOC

                                        PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                                        985 Protection Events

                                        Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                                        Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                                          The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

                                          831 OPTIONS

                                          Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                                          How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                                          1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                                          2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

                                          3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

                                          4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

                                          5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

                                          6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

                                          press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

                                          8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

                                          button on the remote control transmitter or the local keyboard

                                          ndash Disconnect the television set from AC power for at least ten seconds

                                          ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

                                          button on the remote control transmitter or the local keyboard

                                          Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                                          How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                                          enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                                          value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                                          3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                                          91 Introduction

                                          The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                          The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                          92 Source Selection

                                          The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                                          done entirely by the UOC and will only be able to select one external audio source

                                          bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                                          921 Switching Function for Stereo IO

                                          Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                                          922 Switching Function for Mono IO

                                          For the Mono configuration only one input pin is available for the UOC

                                          Video Source SelectionThe video switching is similar to the section above

                                          Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                                          93 Audio

                                          This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                                          931 Processing

                                          This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                                          932 Amplifier

                                          The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                                          Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9

                                          The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                                          933 AVL (Automatic Volume Limiting)

                                          The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                                          Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized

                                          with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information

                                          971 Introduction

                                          The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                                          98 Control

                                          The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                                          981 I2C-Bus

                                          The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                                          982 User Interface

                                          The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                                          983 IO Selection

                                          For the control of the input and output selections there are three lines

                                          STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                                          STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                                          SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                                          984 Power Supply Control

                                          The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                                          STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                          This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                          Figure 9-2 Block diagram of power supply interface with UOC

                                          PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                                          985 Protection Events

                                          Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                                          Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                                            The following options are performed in the Service Default Alignment Mode (SDAM) SDAM is described in the Service Modes Error Codes and Fault Finding sectionThe following alignments are explained1 OPTIONS2 TUNER3 WHITE TONE4 GEOMETRY5 AUDIO

                                            831 OPTIONS

                                            Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                                            How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                                            1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                                            2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

                                            3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

                                            4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

                                            5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

                                            6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

                                            press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

                                            8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

                                            button on the remote control transmitter or the local keyboard

                                            ndash Disconnect the television set from AC power for at least ten seconds

                                            ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

                                            button on the remote control transmitter or the local keyboard

                                            Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                                            How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                                            enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                                            value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                                            3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                                            91 Introduction

                                            The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                            The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                            92 Source Selection

                                            The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                                            done entirely by the UOC and will only be able to select one external audio source

                                            bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                                            921 Switching Function for Stereo IO

                                            Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                                            922 Switching Function for Mono IO

                                            For the Mono configuration only one input pin is available for the UOC

                                            Video Source SelectionThe video switching is similar to the section above

                                            Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                                            93 Audio

                                            This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                                            931 Processing

                                            This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                                            932 Amplifier

                                            The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                                            The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                                            933 AVL (Automatic Volume Limiting)

                                            The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                                            Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized

                                            with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information

                                            971 Introduction

                                            The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                                            98 Control

                                            The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                                            981 I2C-Bus

                                            The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                                            982 User Interface

                                            The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                                            983 IO Selection

                                            For the control of the input and output selections there are three lines

                                            STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                                            STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                                            SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                                            984 Power Supply Control

                                            The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                                            STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                            This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                            Figure 9-2 Block diagram of power supply interface with UOC

                                            PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                                            985 Protection Events

                                            Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                                            Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                                              Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                                              How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                                              1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                                              2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

                                              3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

                                              4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

                                              5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

                                              6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

                                              press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

                                              8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

                                              button on the remote control transmitter or the local keyboard

                                              ndash Disconnect the television set from AC power for at least ten seconds

                                              ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

                                              button on the remote control transmitter or the local keyboard

                                              Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                                              How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                                              enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                                              value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                                              3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                                              91 Introduction

                                              The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                              The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                              92 Source Selection

                                              The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                                              done entirely by the UOC and will only be able to select one external audio source

                                              bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                                              921 Switching Function for Stereo IO

                                              Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                                              922 Switching Function for Mono IO

                                              For the Mono configuration only one input pin is available for the UOC

                                              Video Source SelectionThe video switching is similar to the section above

                                              Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                                              93 Audio

                                              This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                                              931 Processing

                                              This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                                              932 Amplifier

                                              The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                                              Circuit Descriptions List of Abbreviations and IC Data Sheets EN 35L032L AA 9

                                              The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                                              933 AVL (Automatic Volume Limiting)

                                              The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                                              95 Synchronization

                                              Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized

                                              with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information

                                              971 Introduction

                                              The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                                              98 Control

                                              The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                                              981 I2C-Bus

                                              The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                                              982 User Interface

                                              The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                                              983 IO Selection

                                              For the control of the input and output selections there are three lines

                                              STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                                              STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                                              SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                                              984 Power Supply Control

                                              The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                                              STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                              This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                              PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                                              985 Protection Events

                                              Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                                              Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                                                Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                                                How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                                                1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                                                Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                                                How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                                                enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                                                value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                                                3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                                                91 Introduction

                                                The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                                The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                                92 Source Selection

                                                The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                                                done entirely by the UOC and will only be able to select one external audio source

                                                bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                                                921 Switching Function for Stereo IO

                                                Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                                                922 Switching Function for Mono IO

                                                For the Mono configuration only one input pin is available for the UOC

                                                Video Source SelectionThe video switching is similar to the section above

                                                Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                                                93 Audio

                                                This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                                                931 Processing

                                                This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                                                932 Amplifier

                                                The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                                                The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                                                933 AVL (Automatic Volume Limiting)

                                                The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                                                95 Synchronization

                                                Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized

                                                with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information

                                                971 Introduction

                                                The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                                                The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                                                981 I2C-Bus

                                                The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                                                982 User Interface

                                                The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                                                983 IO Selection

                                                For the control of the input and output selections there are three lines

                                                STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                                                STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                                                SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                                                984 Power Supply Control

                                                The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                                                STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                                This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                                PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                                                985 Protection Events

                                                Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                                                Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                                                  Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                                                  How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                                                  1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                                                  4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

                                                  5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

                                                  6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

                                                  press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

                                                  8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

                                                  Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                                                  How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                                                  enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                                                  value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                                                  3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                                                  91 Introduction

                                                  The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                                  The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                                  92 Source Selection

                                                  The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                                                  done entirely by the UOC and will only be able to select one external audio source

                                                  bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                                                  921 Switching Function for Stereo IO

                                                  Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                                                  922 Switching Function for Mono IO

                                                  For the Mono configuration only one input pin is available for the UOC

                                                  Video Source SelectionThe video switching is similar to the section above

                                                  Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                                                  93 Audio

                                                  This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                                                  931 Processing

                                                  This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                                                  932 Amplifier

                                                  The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                                                  The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                                                  933 AVL (Automatic Volume Limiting)

                                                  The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                                                  The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                                                  98 Control

                                                  The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                                                  981 I2C-Bus

                                                  The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                                                  982 User Interface

                                                  The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                                                  983 IO Selection

                                                  For the control of the input and output selections there are three lines

                                                  STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                                                  STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                                                  SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                                                  984 Power Supply Control

                                                  The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                                                  STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                                  This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                                  Figure 9-2 Block diagram of power supply interface with UOC

                                                  PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                                                  985 Protection Events

                                                  Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                                                  Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                                                    Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                                                    How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                                                    enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                                                    value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                                                    3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                                                    91 Introduction

                                                    The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                                    The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                                    92 Source Selection

                                                    The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                                                    done entirely by the UOC and will only be able to select one external audio source

                                                    bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                                                    921 Switching Function for Stereo IO

                                                    Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                                                    922 Switching Function for Mono IO

                                                    For the Mono configuration only one input pin is available for the UOC

                                                    Video Source SelectionThe video switching is similar to the section above

                                                    Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                                                    93 Audio

                                                    This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                                                    931 Processing

                                                    This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                                                    932 Amplifier

                                                    The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                                                    The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                                                    933 AVL (Automatic Volume Limiting)

                                                    The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                                                    bull Whenever there is a loss in the signalbull During cold or warm start MUTE must be activated until all

                                                    initialization processes are finishedbull When the set is going to STANDBY MUTE must be

                                                    activated first before any other activities Note 1 MUTE mentioned above applies to the audio amplifier

                                                    For a detailed circuit description of this part we refer to the L012L AA manual (see the beginning of this chapter for the ordering codes) Please note that there can be minor differences in the text (eg other item numbers) but the described circuit principle is comparable This chassis uses the TDA937x family Ultimate One Chip TV processor (UOC) which is mounted in an SDIP 64 envelope The various versions of the UOC series combine the function of a video processor together with a microcontroller and US Closed CaptionTXT decoder

                                                    95 Synchronization

                                                    Inside IC7200 (part D) the vertical and horizontal sync pulses are separated These H and V signals are synchronized

                                                    with the incoming CVBS signal They are then fed to the H- and V-drive circuits and to the OSDTXT circuit for synchronization of the On Screen Display and Teletext (CC) information

                                                    96 Deflection

                                                    971 Introduction

                                                    The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                                                    98 Control

                                                    The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                                                    981 I2C-Bus

                                                    The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                                                    982 User Interface

                                                    The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                                                    983 IO Selection

                                                    For the control of the input and output selections there are three lines

                                                    STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                                                    STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                                                    SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                                                    984 Power Supply Control

                                                    The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                                                    STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                                    This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                                    Figure 9-2 Block diagram of power supply interface with UOC

                                                    PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                                                    985 Protection Events

                                                    Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                                                    Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                                                      How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                                                      enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                                                      value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                                                      3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                                                      The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                                      The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                                      92 Source Selection

                                                      The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                                                      done entirely by the UOC and will only be able to select one external audio source

                                                      bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                                                      921 Switching Function for Stereo IO

                                                      Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                                                      922 Switching Function for Mono IO

                                                      For the Mono configuration only one input pin is available for the UOC

                                                      Video Source SelectionThe video switching is similar to the section above

                                                      Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                                                      93 Audio

                                                      This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                                                      931 Processing

                                                      This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                                                      932 Amplifier

                                                      The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                                                      The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                                                      933 AVL (Automatic Volume Limiting)

                                                      The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                                                      971 Introduction

                                                      The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                                                      98 Control

                                                      The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                                                      981 I2C-Bus

                                                      The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                                                      982 User Interface

                                                      The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                                                      983 IO Selection

                                                      For the control of the input and output selections there are three lines

                                                      STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                                                      STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                                                      SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                                                      984 Power Supply Control

                                                      The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                                                      STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                                      This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                                      PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                                                      985 Protection Events

                                                      Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                                                      Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                                                        831 OPTIONS

                                                        Options are used to control the presence or absence of certain features and hardware Note Each option byte controls several features of the television set therefore before changing option byte information it is important to record the current option byte values This ensures that the television features can be restored to the original settings if necessary

                                                        How to Change an Option ByteAn Option Byte represents a number of different options Changing these bytes directly makes it possible to set all options very fast All options are controlled via seven option bytes Select the option byte (OP 1 OP 7) with the MENU UPDOWN keys and enter the new value

                                                        1 Activate SDAM by pressing the following key sequence on the remote control transmitter 0 6 2 5 9 6 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence)

                                                        2 Use the MENU UPDOWN keys to highlight the OPTIONS sub menu

                                                        3 Press the MENU LEFT or MENU RIGHT key to enter the OPTIONS sub menu

                                                        4 In the OPTIONS sub menu press the MENU UPDOWN keys to select OP 1 through OP 7

                                                        5 Use the number keys on the remote control transmitter to enter a new value for the selected option byte The value must be entered as a three-digit value (for example 4 would be entered as 0 0 4)

                                                        6 The selected value must be between 0 and 2557 When all desired changes to the option bytes are made

                                                        press the MENU button to return to the top level SDAM menu This will save changes to the option byte settings

                                                        8 To ensure the option byte changes take effectndash Turn the television set off by using the POWER

                                                        button on the remote control transmitter or the local keyboard

                                                        ndash Disconnect the television set from AC power for at least ten seconds

                                                        ndash Reconnect the television set to AC power ndash Turn the television set on by using the POWER

                                                        button on the remote control transmitter or the local keyboard

                                                        Leaving the OPTION submenu saves the changes in the Option Byte settings Some changes will only take effect after the set has been switched OFF and ON with the mains switch (cold start)

                                                        How to Calculate the Value of an Option ByteCalculate an Option Byte value (OP 1 OP 7) in the following way1 Check the status of the single option bits (OB) are they

                                                        enabled (1) or disabled (0)2 When an option bit is enabled (1) it represents a certain

                                                        value (see first column value between brackets in table below) When an option bit is disabled its value is 0

                                                        3 The total value of an Option Byte is formed by the sum of its eight option bits See second table below for the correct Option Bytes per type number

                                                        91 Introduction

                                                        The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                                        The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                                        92 Source Selection

                                                        The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                                                        done entirely by the UOC and will only be able to select one external audio source

                                                        bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                                                        921 Switching Function for Stereo IO

                                                        Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                                                        922 Switching Function for Mono IO

                                                        For the Mono configuration only one input pin is available for the UOC

                                                        Video Source SelectionThe video switching is similar to the section above

                                                        Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                                                        93 Audio

                                                        This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                                                        931 Processing

                                                        This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                                                        932 Amplifier

                                                        The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                                                        The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                                                        933 AVL (Automatic Volume Limiting)

                                                        The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                                                        971 Introduction

                                                        The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                                                        The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                                                        982 User Interface

                                                        The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                                                        983 IO Selection

                                                        For the control of the input and output selections there are three lines

                                                        STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                                                        STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                                                        SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                                                        984 Power Supply Control

                                                        The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                                                        STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                                        This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                                          91 Introduction

                                                          The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                                          The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                                          92 Source Selection

                                                          The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                                                          done entirely by the UOC and will only be able to select one external audio source

                                                          bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                                                          921 Switching Function for Stereo IO

                                                          Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                                                          922 Switching Function for Mono IO

                                                          For the Mono configuration only one input pin is available for the UOC

                                                          Video Source SelectionThe video switching is similar to the section above

                                                          Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                                                          93 Audio

                                                          This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                                                          931 Processing

                                                          This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                                                          The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                                                          971 Introduction

                                                          The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                                                          98 Control

                                                          The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                                                          981 I2C-Bus

                                                          The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                                                          982 User Interface

                                                          The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                                                          983 IO Selection

                                                          For the control of the input and output selections there are three lines

                                                          STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                                                          STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                                                          SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                                                          984 Power Supply Control

                                                          The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                                                          STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                                          This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                                          PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                                                          985 Protection Events

                                                          Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                                                          Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                                                            91 Introduction

                                                            The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                                            The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                                            92 Source Selection

                                                            The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                                                            done entirely by the UOC and will only be able to select one external audio source

                                                            bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                                                            921 Switching Function for Stereo IO

                                                            Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                                                            922 Switching Function for Mono IO

                                                            For the Mono configuration only one input pin is available for the UOC

                                                            Video Source SelectionThe video switching is similar to the section above

                                                            Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                                                            93 Audio

                                                            This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                                                            931 Processing

                                                            This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                                                            932 Amplifier

                                                            The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                                                            The volume level is controlled at this IC (pin 9) by the VOLUME control line coming from the microprocessor After amplification the audio signal is sent to the speaker headphone output connector

                                                            The Mono AVL function operates via the UOC During channel change and source selection the AVL bit is to be switched off and then can return to the previous state (onoff) as shown in the timing diagram below The Stereo AVL function operates via the AGC control of IC TDA9853H During channel change and source selection the AGC function is to be switched off and then can resume to the previous state (onoff) as shown in timing diagram below

                                                            The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                                                            98 Control

                                                            The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                                                            981 I2C-Bus

                                                            The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                                                            982 User Interface

                                                            The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                                                            983 IO Selection

                                                            For the control of the input and output selections there are three lines

                                                            STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                                                            STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                                                            SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                                                            984 Power Supply Control

                                                            The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                                                            STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                                            This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                                            PW_ADJ This signal is generated by the UOC through a PWM port This PWM port is configured in Push Pull mode to generate a square wave signal of 0 to 100 duty cycle with a default value of 50 duty cycle PW_ADJ will eliminate tolerance and can adjust the picture wide slightly

                                                            985 Protection Events

                                                            Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                                                            Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                                                              91 Introduction

                                                              The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                                              The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                                              92 Source Selection

                                                              The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                                                              done entirely by the UOC and will only be able to select one external audio source

                                                              bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                                                              921 Switching Function for Stereo IO

                                                              Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                                                              922 Switching Function for Mono IO

                                                              For the Mono configuration only one input pin is available for the UOC

                                                              Video Source SelectionThe video switching is similar to the section above

                                                              This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                                                              932 Amplifier

                                                              The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                                                              The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                                                              983 IO Selection

                                                              For the control of the input and output selections there are three lines

                                                              STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                                                              STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                                                              The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                                                              STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                                              This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                                                The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                                                The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                                                92 Source Selection

                                                                The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                                                                done entirely by the UOC and will only be able to select one external audio source

                                                                bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                                                                921 Switching Function for Stereo IO

                                                                Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                                                                922 Switching Function for Mono IO

                                                                For the Mono configuration only one input pin is available for the UOC

                                                                Video Source SelectionThe video switching is similar to the section above

                                                                Audio Source SelectionThe audio input (L1_IN) is connected to pin 35 of the UOC

                                                                93 Audio

                                                                This chassis is targeted for the NAFTA market with Mono Stereo or SAP sound system For the basic Mono and Stereo sets sound processing includes Volume control and AVL For stereo sets IC TDA9853H is the BTSC audio signal decoder and audio processing

                                                                931 Processing

                                                                This chassis uses the Intercarrier demodulation concept (one SAW filter for both video and audio) The base band (full bandwidth) BTSC audio signal from the UOC is fed to pin 14 of the stereo decoder The Pilot detection and SAP detection registers indicate the type of transmitted audio signal such as Mono Stereo andor SAP Based on this indication the software controls will help to output the appropriate audio signal at pins 21 and 22 The controls are done by the I2C bus connected to pins 18 and 19 Internal or External audio (pins 2 3 23 and 24) can also be selected by the source selection register For the selected audio source the AGC function can be applied The output is a fixed level output The volume control function is available via the power amplifier (AN752223)

                                                                932 Amplifier

                                                                The output is fed to the audio amplifier (IC7901 for stereo sets or IC7902 for mono sets) This is a BTL amplifier (Bridge Tied Load) which is actually a class AB amplifier with four transistors for each channel The advantage of BTL over the standard Class AB amplifier is that it requires a lower supply voltage to deliver a higher output

                                                                The supply is a Switching Mode Power Supply (SMPS) The frequency of operation varies with the circuit load This Quasi-Resonant Flyback behavior has some important benefits compared to a hard switching fixed frequency Flyback converter The efficiency can be improved up to 90 which results in lower power consumption Moreover the supply runs cooler and safety is enhancedThe control IC in this power supply is the TEA1506 (L01= TEA1507) Unlike the TEA1507 control IC the TEA1506 has no internal high voltage start-up source and therefore needs to be started by means of an external bleeder resistor (R3506 and R3507) The operating voltage for the driver circuit is also taken from the hot side of this transformer The switching regulator IC 7520 starts switching the FET on and off to control the current flow through the primary winding of transformer 5520 The energy stored in the primary winding during the on time is delivered to the secondary windings during the off time The MainSupply line is the reference voltage for the power supply It is sampled by resistors 3543 and 3544 and fed to the input of the regulator 7540 6540 This regulator drives the feedback optocoupler 7515 to set the feedback control voltage on pin 6 of 7520 The power supply in the set is on any time AC power is connected to the set

                                                                972 Derived Voltages

                                                                The microprocessor part of the UOC has the complete control and CCTeletext processing on board The User menus and Service Default Alignment Modes are generated by the uP Communication to other ICs is done via the I2C-bus

                                                                981 I2C-Bus

                                                                The main control system which consists of the microprocessor part of the UOC (7200) is linked to the external devices (Tuner NVM Audio ICs etc) by means of the I2C-bus An internal I2C-bus is used to control other signal processing functions like video processing sound IF vision IF synchronization etc

                                                                982 User Interface

                                                                The chassis uses a remote control with RC5 protocol The incoming signal is connected to pin 67 of the UOCThe keyboard connected to UOC pin 8 can also control the set Button recognition is done via a voltage dividerThe front LED (6691) is connected to an output control line of the microprocessor (pin 11) It is activated to provide the user information about whether or not the set is working correctly (eg responding to the remote control normal operation (USA only) or fault condition)

                                                                983 IO Selection

                                                                For the control of the input and output selections there are three lines

                                                                STATUS1This signal provides information to the microprocessor on whether a video signal is available on the SCART1 AV input and output port (only for Europe) This signal is not connected in LATAMNAFTA sets

                                                                STATUS2This signal provides information to the microprocessor on whether a video signal is available on the SCART2 AV input and output port (only for Europe) For sets with an SVHS input it provides the additional information if a YC or CVBS source is present The presence of an external YC source makes this line high while a CVBS source makes the line low

                                                                SEL_AV1_AV2This is the source select control signal from the microprocessor This control line is under user control or can be activated by the other two control lines

                                                                984 Power Supply Control

                                                                The Power Supply is interfaced with the microcontroller (UOC) to provide the power supply with the control signals required for burst mode operation in standby and to vary the picture width by adjusting V_BAT The microprocessor part is supplied with 33 V and 8 V The 33 V is derived from the VauxVaudio voltage via a 3V3 stabilizer (7493) The 8 V is derived from the 33 V tuner voltage via TS7491 and TS7496Two signals are used to control the power supply STD_CON and PW_ADJ

                                                                STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                                                This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                                                985 Protection Events

                                                                Several protection events are controlled by the UOC In case one of these protections is activated the set will go to Standby mode

                                                                Deflection protectionsThe main protections for deflection are X-ray protection frame amplifier failure detection black current loop stability protection and +8V auxiliary supply protection For X-ray protection the X-ray detection bit XDT must always be set to 1 (detection mode) High EHT protection must be triggered via software upon detection of the XPR bit switching to 1 A suitable number of checks are done before putting the set into protection mode in order to prevent false triggering For service requirements the Enable Vertical Guard (RGB blanking) EVG can be disabled (set to 0) although this is not necessary The following bits are monitoredbull SUP (Supply voltage indication)bull XPR (X-ray protection)bull EVG (Enable Vertical Guard)bull NDF (Output Vertical Guard)bull BCF (Black Current Failure)

                                                                  The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                                                  The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                                                  92 Source Selection

                                                                  The Source Select is divided mainly into two types the Mono Source Select and the Stereo Source Selectbull The Mono Source Select both audio and video will be

                                                                  done entirely by the UOC and will only be able to select one external audio source

                                                                    The L03 chassis is a global TV chassis and is used for TV sets with screen sizes from 14 inch to 21 inch in Super Flat and Real Flat executions In comparison to its predecessor (the L01) this chassis is further simplified it contains economized executions of the power supply the video processing (microprocessor) and the audio processingDue to a cost down action this chassis has some more simplified circuitry like the audio processing and some parts are fully omitted like top-control The standard architecture consists of a Main panel (called family board) and a Picture Tube panel The Main panel consists primarily of conventional components with some surface mounted devices in the audio and video processing part

                                                                    The functions for video processing microprocessor (microP) and CCTeletext (TXT) decoder are combined in one IC (TDA937x) the so-called Ultimate One Chip (UOC) This chip is mounted on the component side of the main panel The L03 can be divided into two basic systems ie mono and stereo sound While the audio processing for the mono sound is done in the audio block of the UOC external audio processing ICs are used for stereo sets The tuning system features 181 channels with on-screen display The main tuning system uses a tuner a microcomputer and a memory IC mounted on the main panel The microcomputer communicates with the memory IC the customer keyboard remote receiver tuner signal processor IC and the audio output IC via the I2C bus The memory IC retains the settings for favorite stations customer-preferred settings and service factory data The on-screen graphics and closed caption decoding are done within the microprocessor where they are added to the main signal The chassis uses a Switching Mode Power Supply (SMPS) for the main voltage source The chassis has a hot ground reference on the primary side and a cold ground reference on the secondary side of the power supply and the rest of the chassis

                                                                    92 Source Selection

                                                                    done entirely by the UOC and will only be able to select one external audio source

                                                                    bull As for the Stereo Source Select the Panasonic IC which is for BTSC decoding also has 2 audio source inputs used for source selection whereas the UOC will take care of the video selection

                                                                    921 Switching Function for Stereo IO

                                                                    Audio Video Source SelectionThe video source selection is done by the UOC The video setting for LATAM NAFTA is rather straightforward a so-called WYSIWYG (what you see on the screen is what you get from the video ouput) There is only a front input available therefore the source selection is basically limited to the UOC

                                                                    922 Switching Function for Mono IO

                                                                    931 Processing

                                                                    932 Amplifier

                                                                    STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                                                    This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                                                    Figure 9-2 Block diagram of power supply interface with UOC

                                                                      STD_CON This signal is generated by the microprocessor when over-current takes place at the Main line This is done to enable the power supply into standby burst mode and to enable this mode during a protection

                                                                      This is of logic high (33 V) under normal operation of the TV When the TV set is in Standby (or fault) condition this signal is a continuous pulse of 5 ms low (0 V) and 5 ms high Note In the L01 chassis this was inverted

                                                                      Figure 9-2 Block diagram of power supply interface with UOC

                                                                      985 Protection Events
