3. Precautions, Notes, and Abbreviation List
Index of this chapter:3.1 Safety Instructions3.2 Warnings3.3 Notes3.4 Abbreviation List
3.1 Safety Instructions
Safety regulations require the following during a repair:• Connect the set to the Mains/AC Power via an isolation
transformer (> 800 VA).• 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. Of de set ontploft!
Safety regulations require that after a repair, the set must be returned in its original condition. Pay in particular attention to the following points: • Route the wire trees correctly and fix them with the
mounted cable clamps.• Check the insulation of the Mains/AC Power lead for
external damage. • Check the strain relief of the Mains/AC Power cord for
proper function.• Check the electrical DC resistance between the Mains/AC
Power plug and the secondary side (only for sets that 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 4.5 MΩ and 12 MΩ.
4. Switch “off” the set, and remove the wire between the two pins of the Mains/AC Power plug.
• Check the cabinet for defects, to prevent touching of any inner parts by the customer.
3.2 Warnings
• 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.
• Be careful during measurements in the high voltage section.
• Never replace modules or other components while the unit is switched “on”.
• 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.
3.3 Notes
3.3.1 General
• 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 with a colour bar signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated otherwise) and
picture carrier at 475.25 MHz for PAL, or 61.25 MHz for NTSC (channel 3).
• 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.
3.3.2 Schematic Notes
• All resistor values are in ohms, and the value multiplier is often used to indicate the decimal point location (e.g. 2K2 indicates 2.2 kΩ).
• Resistor values with no multiplier may be indicated with either an “E” or an “R” (e.g. 220E or 220R indicates 220 Ω).
• All capacitor values are given in micro-farads (μ = × 10-6), nano-farads (n = × 10-9), or pico-farads (p = × 10-12).
• Capacitor values may also use the value multiplier as the decimal point indication (e.g. 2p2 indicates 2.2 pF).
• An “asterisk” (*) indicates component usage varies. Refer to the diversity tables for the correct values.
• The correct component values are listed on the Philips Spare Parts Web Portal.
3.3.3 Spare Parts
For the latest spare part overview, consult your Philips Spare Part web portal.
3.3.4 BGA (Ball Grid Array) ICs
IntroductionFor more information on how to handle BGA devices, visit this URL: http://www.atyourservice-magazine.com. Select “Magazine”, then go to “Repair downloads”. Here you will find Information on how to deal with BGA-ICs.
BGA Temperature ProfilesFor BGA-ICs, you must use the correct temperature-profile. Where applicable and available, this profile is added to the IC Data Sheet information section in this manual.
3.3.5 Lead-free Soldering
Due to lead-free technology some rules have to be respected by the workshop during a repair:• Use only lead-free soldering tin. 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.
• Use only adequate solder tools applicable for lead-free soldering tin. The solder tool must be able:– To reach a solder-tip temperature of at least 400°C.– To stabilize the adjusted temperature at the solder-tip.– To exchange solder-tips for different applications.
• Adjust your solder tool so that a temperature of around 360°C - 380°C is reached and stabilized at the solder joint. Heating time of the solder-joint should not exceed ~ 4 sec. Avoid temperatures above 400°C, otherwise wear-out of tips will increase drastically and flux-fluid will be destroyed. To avoid wear-out of tips, switch “off” unused equipment or reduce heat.
• Mix of lead-free soldering tin/parts with leaded soldering tin/parts is possible but PHILIPS recommends strongly to avoid mixed regimes. If this cannot be avoided, carefully clear the solder-joint from old tin and re-solder with new tin.

3.3.6 Alternative BOM identification
It should be noted that on the European Service website, “Alternative BOM” is referred to as “Design variant”.
The third digit in the serial number (example: AG2B0335000001) indicates the number of the alternative B.O.M. (Bill Of Materials) that has been used for producing the specific TV set. In general, it is possible that the same TV model on the market is produced with e.g. two different types of displays, coming from two different suppliers. This will then result in sets which have the same CTN (Commercial Type Number; e.g. 28PW9515/12) but which have a different B.O.M. number.By looking at the third digit of the serial number, one can identify which B.O.M. is used for the TV set he is working with.If the third digit of the serial number contains the number “1” (example: AG1B033500001), then the TV set has been manufactured according to B.O.M. number 1. If the third digit is a “2” (example: AG2B0335000001), then the set has been produced according to B.O.M. no. 2. This is important for ordering the correct spare parts!For the third digit, the numbers 1...9 and the characters A...Z can be used, so in total: 9 plus 26= 35 different B.O.M.s can be indicated by the third digit of the serial number.
Identification: The bottom line of a type plate gives a 14-digit serial number. Digits 1 and 2 refer to the production centre (e.g. AG is Bruges), digit 3 refers to the B.O.M. code, digit 4 refers to the Service version change code, digits 5 and 6 refer to the production year, and digits 7 and 8 refer to production week (in example below it is 2006 week 17). The 6 last digits contain the serial number.
Figure 3-1 Serial number (example)
3.3.7 Board Level Repair (BLR) or Component Level Repair (CLR)
If a board is defective, consult your repair procedure to decide if the board has to be exchanged or if it should be repaired on component level.If your repair procedure says the board should be exchanged completely, do not solder on the defective board. Otherwise, it cannot be returned to the O.E.M. supplier for back charging!
3.3.8 Practical Service Precautions
• 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.
• 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.

4.2 Service Positions
For easy servicing of a TV set, the set should be put face down on a soft flat surface, foam buffers or other specific workshop tools. Ensure that a stable situation is created to perform measurements and alignments. When using foam bars take care that these always support the cabinet and never only the display. Caution: Failure to follow these guidelines can seriously damage the display! Ensure that ESD safe measures are taken.

In the chassis schematics and layout overviews, the test points are mentioned. In the schematics, test points are indicated with “Fxxx” or “Ixxx”, in the layout overviews with a “half-moon” sign.As most signals are digital, it will be difficult to measure waveforms with a standard oscilloscope. Several key ICs are capable of generating test patterns, which can be controlled via ComPair. In this way it is possible to determine which part is defective. Perform measurements under the following conditions:• Service Default Mode.• Video: Color bar signal.• Audio: 3 kHz left, 1 kHz right.
5.2 Service Modes
The Service Mode feature is split into four parts: • Service Default Mode (SDM).• Service Alignment Mode (SAM).• Customer Service Mode (CSM).• Computer Aided Repair Mode (ComPair). SDM and SAM offer features, which can be used by the Service engineer to repair/align a TV set. Some features are: • A pre-defined situation to ensure measurements can be
made under uniform conditions (SDM).• Activates the blinking LED procedure for error identification
when no picture is available (SDM).• The possibility to overrule software protections when SDM
is entered via the Service pins.• Make alignments (e.g. White Tone), (de)select options,
enter options codes, reset the error buffer (SAM).• Display information (“SDM” or “SAM” indication in upper
right corner of screen, error buffer, software version, operating hours, options and option codes, sub menus).
The CSM is a Service Mode that can be enabled by the consumer. The CSM displays diagnosis information, which the customer can forward to the dealer or call centre. In CSM mode, “CSM”, is displayed in the top right corner of the screen. The information provided in CSM and the purpose of CSM is to:• Increase the home repair hit rate.• Decrease the number of nuisance calls.• Solved customers' problem without home visit. ComPair Mode is used for communication between a computer and a TV on I2C /UART level and can be used by a Service engineer to quickly diagnose the TV set by reading out error codes, read and write in NVMs, communicate with ICs and the uP (PWM, registers, etc.), and by making use of a fault finding database. It will also be possible to up and download the software of the TV set via I2C with help of ComPair. To do this, ComPair has to be connected to the TV set via the ComPair connector, which will be accessible through the rear of the set (without removing the rear cover).
5.2.1 Service Default Mode (SDM)
PurposeSet the TV in SDM mode in order to be able to:• Create a pre-defined setting for measurements to be
made.• Override software protections.• Start the blinking LED procedure.• Read the error buffer.• Check the life timer.
Specifications
Table 5-1 SDM default settings
• Set linear video and audio settings to 50%, but volume to 25%. Stored user settings are not affected.
• All service-unfriendly modes (if present) are disabled, since they interfere with diagnosing/repairing a set. These service unfriendly modes are:– (Sleep) timer.– Blue mute/Wall paper.– Auto switch “off” (when there is no “ident” signal).– Hotel or hospital mode.– Child lock or parental lock (manual or via V-chip).– Skipping, blanking of “Not favorite”, “Skipped” or
“Locked” presets/channels.– Automatic storing of Personal Preset or Last Status
settings.– Automatic user menu time-out (menu switches back/
OFF automatically.– Auto Volume levelling (AVL).
How to Activate SDM
For this chassis there are two kinds of SDM: an analog SDM and a digital SDM. Tuning will happen according Table 5-1.• Analog SDM: use the standard RC-transmitter and key in
the code “062596”, directly followed by the “MENU” (or HOME) button. Note: It is possible that, together with the SDM, the main menu will appear. To switch it “off”, push the “MENU” (or HOME) button again.
• Digital SDM: use the standard RC-transmitter and key in the code “062593”, directly followed by the “MENU” (or HOME) button.Note: It is possible that, together with the SDM, the main menu will appear. To switch it “off”, push the “MENU” (or HOME) button again.
• Analog SDM can also be activated by grounding for a moment the solder pad on the SSB, with the indication “SDM” (see figure Service mode pad).

After activating this mode, “SDM” will appear in the upper right corner of the screen (when a picture is available).
How to NavigateWhen the “MENU” (or HOME) button is pressed on the RC transmitter, the TV set will toggle between the SDM and the normal user menu.
How to Exit SDMUse one of the following methods:• Switch the set to STAND-BY via the RC-transmitter. • Via a standard customer RC-transmitter: key in “00”-
sequence.
5.2.2 Service Alignment Mode (SAM)
Purpose• To perform (software) alignments.• To change option settings.• To easily identify the used software version.• To view operation hours.• To display (or clear) the error code buffer.
How to Activate SAMVia a standard RC transmitter: Key in the code “062596” directly followed by the “INFO” button. After activating SAM with this method a service warning will appear on the screen, continue by pressing the “OK” button on the RC.
Contents of SAM (see also Table 6-6)• Hardware Info.
– A. SW Version. Displays the software version of the main software (example: LC93L-1.2.3.4= AAAAB_X.Y.W.Z). • AAAA= the chassis name.• B= the region (A= Asian Pacific, E= Europe, L=
Latam, U= United States).• X.Y.W.Z= the software version, where X is the
main version number (different numbers are not compatible with one another) and Y.W.Z is the sub version number (a higher number is always compatible with a lower number).
– B. Standby Processor Version. Displays the software version of the Stand-by processor.
– C. Production Code. Displays the production code of the TV, this is the serial number as printed on the back of the TV set. Note that if an NVM is replaced or is initialized after corruption, this production code has to be re-written to NVM. ComPair will foresee in a possibility to do this.
• Operation Hours. Displays the accumulated total of operation hours (not the stand-by hours). Every time the TV is switched “on/off”, 0.5 hours is added to this number.
• Errors (followed by maximum 10 errors). The most recent error is displayed at the upper left (for an error explanation see section “5.4 Error Codes”).
• Reset Error Buffer. When “cursor right” (or the “OK button) is pressed and then the “OK” button is pressed, the error buffer is reset.
• Alignments. This will activate the “ALIGNMENTS” sub-menu. See chapter 6.3 Software Alignments.
• Dealer Options. Extra features for the dealers.• Options. Extra features for Service. For more information
about option codes, refer to 6.4 Option Settings. Note that if the option code numbers are changed, these have to be confirmed with pressing the “OK” button before the options are stored. Otherwise changes will be lost.
• Initialize NVM. The moment the processor recognizes a corrupted NVM, the “initialize NVM” line will be highlighted. Now, two things can be done (dependent of the service instructions at that moment):– Save the content of the NVM via ComPair for
development analysis, before initializing. This will give the Service department an extra possibility for diagnosis (e.g. when Development asks for this).
– Initialize the NVM.
Note: When the NVM is corrupted, or replaced, there is a high possibility that no picture appears because the display code is not correct. So, before initializing the NVM via the SAM, a picture is necessary and therefore the correct display option has to be entered. To adapt this option bit, it is advised to use ComPair (the correct values for the options can be found in Table 6-5) or a method via a standard RC (described below).
Changing the display option via a standard RC: Key in the code “062598” directly followed by the “MENU” (or HOME) button and “XXX” (where XXX is the 3 digit decimal display code as mentioned in Table 6-5). Make sure to key in all three digits, also the leading zero’s. If the above action is successful, the front LED will go out as an indication that the RC sequence was correct. After the display option is changed in the NVM, the TV will go to the Stand-by mode. If the NVM was corrupted or empty before this action, it will be initialized first (loaded with default values). This initializing can take up to 20 seconds.

• Operation hours display. Displays the accumulated total of display operation hours. So, this one keeps up the lifetime of the display itself, mainly to compensate the degeneration behavior.
• Test settings. For development purposes only.• Development file versions. Not useful for Service
purposes, this information is only used by the development department.
• Upload to USB. To upload several settings from the TV to an USB stick, which is connected to the SSB. The items are “Channel list”, “Personal settings”, “Option codes”, “Display-related alignments” and “History list”. First a directory “repair\” has to be created in the root of the USB stick. To upload the settings select each item separately, press “cursor right” (or the “OK” button), confirm with “OK” and wait until “Done” appears. In case the download to the USB stick was not successful “Failure” will appear. In this case, check if the USB stick is connected properly and if the directory “repair” is present in the root of the USB stick. Now the settings are stored onto the USB stick and can be used to download onto another TV or other SSB. Uploading is of course only possible if the software is running and if a picture is available. This method is created to be able to save the customer’s TV settings and to store them into another SSB.
• Download to USB. To download several settings from the USB stick to the TV, same way of working needs to be followed as with uploading. To make sure that the download of the channel list from USB to the TV is executed properly, it is necessary to restart the TV and tune to a valid preset if necessary.Note: The “History list item” can not be downloaded from USB to the TV. This is a “read-only” item. In case of specific problems, the development department can ask for this info.
How to Navigate• In SAM, the menu items can be selected with the
“CURSOR UP/DOWN” key on the RC-transmitter. The selected item will be highlighted. When not all menu items fit on the screen, move the “CURSOR UP/DOWN” key to display the next/previous menu items.
• With the “CURSOR LEFT/RIGHT” keys, it is possible to:– (De) activate the selected menu item.– (De) activate the selected sub menu.
• With the “OK” key, it is possible to activate the selected action.
How to Exit SAMUse one of the following methods:• Switch the TV set to STAND-BY via the RC-transmitter.• Via a standard RC-transmitter, key in “00” sequence, or
select the “BACK” key.
5.2.3 Customer Service Mode (CSM)
PurposeThe Customer Service Mode shows error codes and information on the TV’s operation settings. A call centre can instruct the customer (by telephone) to enter CSM in order to identify the status of the set. This helps them to diagnose problems and failures in the TV before making a service call.The CSM is a read-only mode; therefore, modifications are not possible in this mode.
Specifications• Ignore “Service unfriendly modes”.• Line number for every line (to make CSM language
independent).• Set the screen mode to full screen (all contents on screen
is visible).• After leaving the Customer Service Mode, the original
settings are restored.
• Possibility to use “CH+” or “CH-” for channel surfing, or enter the specific channel number on the RC.
How to ActivateTo activate CSM, press the following key sequence on a standard remote control transmitter: “123654” (do not allow the display to time out between entries while keying the sequence).
Contents of CSMThe contents are reduced to 3 pages: General, Software versions and Quality items. The group names itself are not shown anywhere in the CSM menu.
General• Set Type. This information is very helpful for a helpdesk/
workshop as reference for further diagnosis. In this way, it is not necessary for the customer to look at the rear of the TV-set. Note that if an NVM is replaced or is initialized after corruption, this set type has to be re-written to NVM. ComPair will foresee in a possibility to do this.
• Production Code. Displays the production code (the serial number) of the TV. Note that if an NVM is replaced or is initialized after corruption, this production code has to be re-written to NVM. ComPair will foresee a in possibility to do this.
• Installed date. Indicates the date of the first installation of the TV. This date is acquired via time extraction.
• Options 1. Gives the option codes of option group 1 as set in SAM (Service Alignment Mode).
• Options 2. Gives the option codes of option group 2 as set in SAM (Service Alignment Mode).
• 12NC SSB. Gives an identification of the SSB as stored in NVM. Note that if an NVM is replaced or is initialized after corruption, this identification number has to be re-written to NVM. ComPair will foresee in a possibility to do this. This identification number is the 12nc number of the SSB.
• 12NC display. Shows the 12NC of the display.• 12NC supply. Shows the 12NC of the supply.
Software versions• Current main SW. Displays the built-in main software
version. In case of field problems related to software, software can be upgraded. As this software is consumer upgradable, it will also be published on the Internet.Example: LC92L_1.2.3.4
• Ambilight SW. Displays the Ambilight SW-version.
Quality items• Signal quality. Poor / average /good• Child lock. Not active / active. This is a combined item for
locks. If any lock (Preset lock, child lock, lock after or parental lock) is active, the item shall show “active”.
• HDMI HDCP key. Indicates if the HDMI keys (or HDCP keys) are valid or not. In case these keys are not valid and the customer wants to make use of the HDMI functionality, the SSB has to be replaced.
• Ethernet MAC address. Displays the MAC address present in the SSB.
• BDS key. Indicates if the “BDS level” key is valid or not.

5.3 Service Tools
5.3.1 ComPair
IntroductionComPair (Computer Aided Repair) is a Service tool for Philips Consumer Lifestyle products. and offers the following:1. ComPair helps you to quickly get an understanding on how
to repair the chassis in a short and effective way.2. ComPair allows very detailed diagnostics and is therefore
capable of accurately indicating problem areas. You do not have to know anything about I2C or UART commands yourself, because ComPair takes care of this.
3. ComPair speeds up the repair time since it can automatically communicate with the chassis (when the uP is working) and all repair information is directly available.
4. ComPair features TV software up possibilities.
SpecificationsComPair consists of a Windows based fault finding program and an interface box between PC and the (defective) product. The (new) ComPair II interface box is connected to the PC via an USB cable. For the TV chassis, the ComPair interface box and the TV communicate via a bi-directional cable via the service connector(s).
How to ConnectThis is described in the ComPair chassis fault finding database.
Figure 5-3 ComPair II interface connection
Caution: It is compulsory to connect the TV to the PC as shown in the picture above (with the ComPair interface in between), as the ComPair interface acts as a level shifter. If one connects the TV directly to the PC (via UART), ICs will be blown!
How to OrderComPair II order codes:• ComPair II interface: 3122 785 91020.• ComPair UART interface cable: 3138 188 75051.• Program software can be downloaded from the Philips
Service portal. Note: If you encounter any problems, contact your local support desk.
5.4 Error Codes
5.4.1 Introduction
The error code buffer contains all detected errors since the last time the buffer was erased. The buffer is written from left to right, new errors are logged at the left side, and all other errors shift one position to the right. When an error occurs, it is added to the list of errors, provided the list is not full. When an error occurs and the error buffer is full, then the new error is not added, and the error buffer stays intact (history is maintained).To prevent that an occasional error stays in the list forever, the error is removed from the list after more than 50 hrs. of operation. When multiple errors occur (errors occurred within a short time span), there is a high probability that there is some relation between them. New in this chassis is the way errors are displayed:• There is a simple blinking LED procedure for board level
repair (home repair) so called LAYER 1 errors, next to the existing errors which are LAYER 2 errors (see Table 5-3).– LAYER 1 errors are one digit errors (via CSM).– LAYER 2 errors are 2 digit errors (via SAM/SDM).
• In protection mode:– From consumer mode: LAYER 1.– From SDM mode: LAYER 2.
• In CSM mode: When entering CSM: error LAYER 1 will be displayed by blinking LED. Only the latest error is shown.
• In SDM mode: When SDM is entered via Remote Control code or the hardware pins, LAYER 2 is displayed via blinking LED.
• In the “ON” state: with the RC commands “mute_06250X _OK”, LAYER 2 errors are displayed via blinking LED.
• Error display on screen:– In CSM no error codes are displayed on screen.– In SAM the complete error list is shown.
5.4.2 How to Read the Error Buffer
Use one of the following methods:• On screen via the SAM (only when a picture is visible).
E.g.:– 00 00 00 00 00: No errors detected– 23 00 00 00 00: Error code 23 is the last and only
detected error.– 37 23 00 00 00: Error code 23 was first detected and
error code 37 is the last detected error.– Note that no protection errors can be logged in the
error buffer.• Via the blinking LED procedure. See section 5.4.3 How to
Clear the Error Buffer.• Via ComPair.
5.4.3 How to Clear the Error Buffer
Use one of the following methods:• By activation of the “Reset error buffer” command in the
SAM menu.• With a normal RC, key in sequence “MUTE” followed by
“062599” and “OK”.• If the content of the error buffer has not changed for 50+
hours, it resets automatically.

5.4.4 Error Buffer
In case of non-intermittent faults, clear the error buffer before starting to repair (before clearing the buffer, write down the content, as this history can give significant information). This 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 (e.g. a fault in the protection detection circuitry can also lead to a protection). Take notice that some errors need several minutes before they start blinking or before they will be logged. So in case of problems wait 2 minutes from start-up onwards, and then check if the front LED is blinking or if an error is logged.
Table 5-2 Layer 1 error codes
Table 5-3 Error code overview
5.5 The Blinking LED Procedure
5.5.1 Introduction
The software is capable of identifying different kinds of errors. Because it is possible that more than one error can occur over time, an error buffer is available, which is capable of storing the last five errors that occurred. This is useful if the OSD is not working properly. Errors can also be displayed by the blinking LED procedure. The method is to repeatedly let the front LED pulse with as many pulses as the error code number, followed by a period of 1.5 seconds in which the LED is “off”. Then this sequence is repeated. Example (1): error code 4 will result in four times the sequence LED “on” for 0.25 seconds / LED “off” for 0.25 seconds. After this sequence, the LED will be “off” for 1.5 seconds. Any RC5 command terminates the sequence. Error code LED blinking is in red color. Example (2): the content of the error buffer is “12 9 6 0 0” After entering SDM, the following occurs: • 1 long blink of 5 seconds to start the sequence,• 12 short blinks followed by a pause of 1.5 seconds,• 9 short blinks followed by a pause of 1.5 seconds,• 6 short blinks followed by a pause of 1.5 seconds,• 1 long blink of 1.5 seconds to finish the sequence,• The sequence starts again with 12 short blinks.
5.5.2 Displaying the Entire Error Buffer
Additionally, the entire error buffer is displayed when Service Mode “SDM” is entered. In case the TV set is in protection or Stand-by: The blinking LED procedure sequence (as in SDM-mode in normal operation) must be triggered by the following RC sequence: “MUTE” “062500” “OK”.
In order to avoid confusion with RC5 signal reception blinking, this blinking procedure is terminated when a RC5 command is received.

5.6 Fault Finding and Repair Tips
Notes: • It is assumed that the components are mounted correctly
with correct values and no bad solder joints. • Before any fault finding actions, check if the correct
options are set.
5.6.1 Software Protections
Most of the protections and errors use either the stand-by or the micro processor as detection device. Since in these cases, checking of observers, polling of ADCs, and filtering of input values are all heavily software based, these protections are referred to as software protections.There are several types of software related protections, solving a variety of fault conditions:• Protections related to supplies: check of the 12V.• Protections related to breakdown of the safety check
mechanism. E.g. since the protection detections are done by means of software, failing of the software will have to initiate a protection mode since safety cannot be guaranteed any more.
Remark on the Supply ErrorsThe detection of a supply dip or supply loss during the normal playing of the set does not lead to a protection, but to a cold reboot of the set. If the supply is still missing after the reboot, the TV will go to protection.
Protections during Start-upDuring TV start-up, some voltages and IC observers are actively monitored to be able to optimize the start-up speed, and to assure good operation of all components. If these monitors do not respond in a defined way, this indicates a malfunction of the system and leads to a protection.
5.6.2 Hardware Protections
The only real hardware protection in this chassis is (in case of an audio problem) the audio protection circuit that will trigger the uP to switch “off” the TV.
Repair Tip• It is also possible that you have an audio DC protection
because of an interruption in one or both speakers (the DC voltage that is still on the circuit cannot disappear through the speakers). Caution: (dis)connecting the speaker wires during the ON state of the TV at high volume can damage the audio amplifier.
5.6.3 Logging
When something is wrong with the TV set (f.i.the set is rebooting) you can check for more information via the logging in Hyperterminal. The Hyperterminal is available in every Windows application via Programs, Accessories, Communications, Hyperterminal. Connect a “ComPair UART”-cable (3138 188 75051) from the service connector in the TV to the “multi function” jack at the front of ComPair II box.Required settings in ComPair before starting to log:- Start up the ComPair application.- Select the correct database (open file “Q549.3E LA”, this will set the ComPair interface in the appropriate mode).- Close ComPairAfter start-up of the Hyperterminal, fill in a name (f.i. “logging”) in the “Connection Description” box, then apply the following settings: 1. COMx2. Bits per second = 1152003. Data bits = 84. Parity = none
5. Stop bits = 16. Flow control = noneDuring the start-up of the TV set, the logging will be displayed. This is also the case during rebooting of the TV set (the same logging appears time after time). Also available in the logging is the “Display Option Code” (useful when there is no picture), look for item “DisplayRawNumber” in the beginning of the logging. Tip: when there is no picture available during rebooting you are able to check for “error devices” in the logging (LAYER 2 error) which can be very helpful to determine the failure cause of the reboot. For protection state, there is no logging.
5.6.4 Display option code
Caution: In case you have replaced the SSB, always check the display option code in SAM, even if you have picture. With a wrong display option code it is possible that you have picture, but that in certain conditions you have unwanted side-effects.
5.6.5 Trouble Shooting Tuner section
When there is no picture in analog RF mode:1. Check whether picture is present in AV mode. If not, tuner
section is okay. Check video processing section.2. Check if option settings are correct.3. Check if 5 and 33 V supplies are available.4. Check if the I2C lines are working correctly (3.3 V).5. Manually store a known channel and check if there is IF
output at tuner pin 11. If not, tuner is faulty.6. Feed in 105 dBuV at tuner pin 11 and check whether there
is CVBS output from IF demodulator IC. If not, IF demodulator might be faulty. Check components in this area.
5.7 Software Upgrading
5.7.1 Introduction
It is possible for the user to upgrade the main software via the USB port. This allows replacement of a software image in a stand alone set, without the need of an E-JTAG debugger. A description on how to upgrade the main software can be found in the DFU.
Important: When the NAND-Flash must be replaced, a new SSB must be ordered, due to the presence of the security keys! (copy protection keys, MAC address, ...).Perform the following actions after SSB replacement:1. Set the correct option codes (see sticker inside the TV).2. Update the TV software => see the DFU for instructions.3. Perform the alignments as described in chapter 6.4. Check in CSM if the HDMI key, MAC address.. are valid.For the correct order number of a new SSB, always refer to the Spare Parts list on the Philips Service web portal!
5.7.2 Software Upgrade
SW versions can be divided in three types:• SW that can not crash the working of the set.
– EDID NVM. If the download fails, the set is still running and the download can start again.
– Main NVM: If the download fails the default NVM value can be loaded. NVM can be loaded via USB, be aware PCBA alignments stored in NVM will not be overridden.
• SW that is “fool proof”: There is a backup version, a main interruption during upgrade shall not crash the normal working, a new upgrade can be started. – Main SW image: Upgradable via USB.– Standby SW.– ARM Ambilight (if applicable): Upgradable via USB.
• SW that is not “fool proof”.
Service Modes, Error Codes, and Fault Finding EN 23LC9.3L LA 5.

– Bootloader: Upgradable via USB in SAM (Note: must be done by service personnel).
SW for all model numbers is loaded to the Philips Service portal (P4S) and contains the following software:• Process_NVM_LC09Mxxx.bin: mainly for factory use to
load main NVM. Can be used by service if applicable.• LC09M_VGAxxxx.bin: for loading VGA NVM using
ComPair tool.• LC09M_HDMIxxxx.bin: for loading HDMI NVM via
ComPair (HDMI MUX EDID) tool.• The Autorun.upg file, which is available on P4C (the
consumer web site), contains:– Main SW.– Standby SW.– Bootloader SW (via SAM upgradable).– Ambilight SW (if applicable).

6. Alignments
Index of this chapter:6.1 General Alignment Conditions6.2 Hardware Alignments6.3 Software Alignments6.4 Option Settings Note: Figures below can deviate slightly from the actual situation, due to the different set executions.
General: The Service Default Mode (SDM) and Service Alignment Mode (SAM) are described in chapter 5. Menu navigation is done with the CURSOR UP, DOWN, LEFT or RIGHT keys of the remote control transmitter.
6.1 General Alignment Conditions
Perform all electrical adjustments under the following conditions:• Power supply voltage: 120 - 230 VAC / 50 Hz (± 10%).• Connect the set to the mains via an isolation transformer
with low internal resistance.• Allow the set to warm up for approximately 15 minutes.• Measure voltages and waveforms in relation to correct
ground (e.g. measure audio signals in relation to AUDIO_GND). Caution: It is not allowed to use heatsinks as ground.
• Test probe: Ri > 10 Mohm, Ci < 20 pF.• Use an isolated trimmer/screwdriver to perform
alignments.
6.2 Hardware Alignments
There are no hardware alignments foreseen for this chassis, but below find an overview of the most important DC voltages on the SSB. These can be used for checking proper functioning of the DC/DC converters.
6.3 Software Alignments
Put the set in SAM mode (see chapter 5. Service Modes, Error Codes, and Fault Finding). The SAM menu will now appear on the screen. Select ALIGNMENTS and go to one of the sub menus. The alignments are explained below.
The following item can be aligned:• Whitepoint.
To store the data:
• Press OK on the RC before the cursor is moved to the left.• In main menu select “Store” and press OK on the RC.• Press MENU on the RC to switch back to the main menu.• Switch the set to stand-by mode.
For the next alignments, supply the following test signals via a video generator to the RF input:• LATAM models: an NTSC M TV-signal with a signal
strength of at least 1 mV and a frequency of 61.25 MHz (channel 3).
6.3.1 White Point
• Set “Active control” to “Off”.• Choose “TV menu”, “TV Settings” and then “Picture” and
set picture settings as follows:
• Go to the SAM and select “Alignments”-> “White point”.
White point alignment LCD screens:• Use a 100% white screen as input signal and set the
following values (in SAM mode): – “Color temperature” to “Cool”.– “Whitepoint red”, “Whitepoint green”, and “Whitepoint
blue” values to “127”.– “Red BL offset” and “Green BL offset” values to “7”.
With a color analyzer:Depending on which color analyzer you use (CS-200 or CA-210), and what kind of panel is mounted in the set (CCFL with panel codes 231/232, or LED with panel codes 233/234/236), different values apply. Refer to • Measure with a calibrated, contactless (max. 25 mm
distance) color analyzer in the centre of the screen. Consequently, the measurement needs to be done in a dark environment.
• Adjust one or two registers (so holding one of the White point registers R, G or B on 127) to obtain the “Cool” x,y values (see Table 6-1). Tolerance: dx: ± 0.004, dy: ± 0.004.
• Repeat this step for the “Normal” and “Warm” color temperatures.
• When finished press “OK” on the RC and then press “Store” (in the SAM root menu) to store the aligned values into the NVM.
• Restore the initial picture settings after the alignments.

Without a color analyzer, you can use below default values. This is the next best solution. The default values are average values coming from production (statistics).• Select a “Color Temperature” (e.g. “Cool”, “Normal”, or
“Warm”).• Set the “Whitepoint Red”, “- Green” and “- Blue” default
values according to the values in the “Tint settings” table.• When finished press “OK” on the RC, then press “Store” (in
the SAM root menu) to store the aligned values into the NVM.
• Restore the initial picture settings after the alignments.

6.4 Option Settings
6.4.1 Introduction
The microprocessor communicates with a large number of I2C ICs in the set. To ensure good communication and to make digital diagnosis possible, the microprocessor has to know which ICs to address. The presence/absence of these specific ICs (or functions) is made known by the option codes. Notes: • After changing the option(s), save them with the STORE
command.• The new option setting becomes active after the TV is
switched “off” and “on” again with the mains switch (the EAROM is then read again).
6.4.2 Dealer Options
For dealer options, in SAM select “Dealer options”.See Table 6-6.
6.4.3 (Service) Options
Select the sub menu's to set the initialization codes (options) of the model number via text menus.See Table 6-6.
6.4.4 Opt. No. (Option numbers)
Select this sub menu to set all options at once (expressed in two long strings of numbers).An option number (or “option byte”) represents a number of different options. When you change these numbers directly, you can set all options very quickly. All options are controlled via eight option numbers.When the NVM is replaced, all options will require resetting. To be certain that the factory settings are reproduced exactly, you must set both option number lines. You can find the correct option numbers on a sticker inside the TV set and in Table “Option code overview”.
Example: The options sticker gives the following option numbers:• 25604 00386 00235 56068 • 08395 05120 00000 00000
The first line (group 1) indicates hardware options 1 to 4. Example: option no. “2” contains the “cabinet type”. The second line (group 2) indicates software options 5 to 8. Example: option no. “5” contains the “display code”.Every 5-digit number represents 16 bits (so the maximum value will be 65536 if all options are set).When all the correct options are set, the sum of the decimal values of each Option Byte (OB) will give the option number.See Table 6-5 for the options. Always refer to the sticker in the TV-set as leading.
DiversityNot all sets with the same Commercial Type Number (CTN) necessarily have the same option code!
Use of Alternative BOMAn alternative BOM number usually indicates the use of an alternative display. This results in another Display Code thus in another Option code. Refer to chapter 3. Precautions, Notes, and Abbreviation List.

Below find an explanation of the signals that are used:• USB_OC:
– normal operation signal level is “HIGH” (logic “1”)– when the 5V supply to the USB device exceeds a
current limit of 700 mA, the RT9715HGS will pull the signal level to “LOW” state (logic “0”), which will restart the set
– if the die temperature exceeds 120 degrees C, the signal will be “LOW” (logic “0”), which will restart the set
• USB_PWR_EN: to enable or disable the USB power switch RT9715HGS; to enable, this signal must be set to logic “0”
• USB_DM, USB_DP: USB differential signal.

SSB: SRP List Explanation
1 . 1 . Introduction
Example
SRP (Service Re ference Protocol) is a softw are too l that creates a list w i th all refer e n c es to signal lines. The list contains references to the signals w i thin all schemat ics of a PWB. It replaces the text refe r ences currentl y p r inted next t o the signal names in the schematics. These printed refe rences are created man ually an d are t h e r efore n o t guar an teed to be 100 % correct. In additio n , in the current crowded schema t ics there is often none or ver y little pl ace for these references. Either there will be an SRP reference list for a schematic, or there will be printed references in the schematic.
1.2. Non-SRP Schematics
There are several different signals available in a schematic:
1.2.1. Power Supply Lines
All power supply lines are available in the supply line overview (see chapter 9). In the schematics (see chapter 10) is notindicated where supplies are coming from or going to. It is however indicated if a supply is incoming (created elsewhere), or outgoing (created or adapted in the current schematic).
+5V +5V
Outgoing Incoming
1.2.2. Normal Signals
For normal signals, a schematic reference (e.g. B14b) is placed next to the signals.
signal_nameB14b
1.2.3. Grounds
For normal and special grounds (e.g. GNDHOT or GND3V3 etc.), nothing is indicated.
1.3. SRP Schematics
SRP is a tool, which automatically creates a list with signal references, indicating on which schematic the signals are used.A reference is created for all signals indicated with an SRP symbol, these symbols are:
+5V +5V Power supply line.
name name Stand alone signal or switching line (used as less as possible).
name name
Signal line into a wire tree.
name name
Switching line into a wire tree.
name
Bi-directional line (e.g. SDA) into a wire tree.
name
Signal line into a wire tree, its direction depends on the circuit (e.g. ingoing for PDP, outgoing for LCD sets).
Remarks:• When there is a black dot on the “signal direction arrow” it is an SRP symbol, so there will be a reference to the signal
name in the SRP list. • All references to normal grounds (Ground symbols without additional text) are not listed in the reference list, this to keep
it concise. • Signals that are not used in multiple schematics, but only once or several times in the same schematic, are included
in the SRP reference list, but only with one reference.
Additional Tip:
When using the PDF service manual file, you can very easily search for signal names and follow the signal over all the schematics. In Adobe PDF reader: • Select the signal name you want to search for, with the “Select text” tool. • Copy and paste the signal name in the “Search PDF” tool. • Search for all occurrences of the signal name. • Now you can quickly jump between the different occurrences and follow the signal over all schematics. It is advised to
“zoom in” to e.g. 150% to see clearly, which text is selected. Then you can zoom out, to get an overview of the complete schematic.
PS. It is recommended to use at least Adobe PDF (reader) version 6.x, due to better search possibilities in this version.
