Power consumption (values are indicative) - Normal operation (W) : 110 (32") : 170 (42") - Stand-by (W) : 800 VA). Replace safety components, indicated by the symbol h, 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. 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 Mohm and 12 Mohm. 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.

2.3.2

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 kohm). Resistor values with no multiplier may be indicated with either an "E" or an "R" (e.g. 220E or 220R indicates 220 ohm). All capacitor values are given in micro-farads (= x10-6), nano-farads (n= x10-9), or pico-farads (p= x10-12). 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 in the Spare Parts List. Therefore, always check this list when there is any doubt.

2.3.3

BGA (Ball Grid Array) ICs Introduction For more information on how to handle BGA devices, visit this URL: www.atyourservice.ce.philips.com (needs subscription, not available for all regions). After login, select Magazine, then go to Repair downloads. Here you will find Information on how to deal with BGA-ICs. BGA Temperature Profiles 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 www.atyourservice.ce.philips.com (needs subscription, but is not available for all regions) You will find this and more technical information within the "Magazine", chapter "Repair downloads". For additional questions please contact your local repair help desk.

2.2

Warnings All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD w). 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: Complete kit ESD3 (small tablemat, wristband, connection box, extension cable and earth cable) 4822 310 10671. Wristband tester 4822 344 13999. 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.

2.3.4

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 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. 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 400C. 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 360C - 380C is reached and stabilized at the solder joint. Heating time of the solder-joint should not exceed ~ 4 sec. Avoid temperatures above 400C, otherwise wear-out of tips will increase drastically and flux-fluid will be destroyed.

2.32.3.1

NotesGeneral Measure the voltages and waveforms with regard to the chassis (= tuner) ground (H), or hot ground (I), depending on the tested area of circuitry. The voltages and waveforms shown in the diagrams are indicative. Measure them in the

Directions for UseTo 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.

BJ3.0E LAE_06532_024.eps 130606

2.3.5

Alternative BOM identification 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.

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!

2.3.7

NVM content If the processor NVM IC is replaced or initialised, the Model Number, Serial Number, and SSB Code number must be rewritten to the NVM. ComPair will foresee in a possibility to do this.

2.3.8

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.

Service Modes, Error Codes, and Fault FindingIndex of this chapter: 5.1 Test Points 5.2 Service Modes 5.3 Service Tools 5.4 Error Codes 5.5 The Blinking LED Procedure 5.6 Software Upgrading 5.7 Fault Finding and Repair Tips 5.2.1 General Some items are applicable to all Service Modes or are general. These are listed below. Life Timer During the life time cycle of the TV set, a timer is kept. It counts the normal operation hours (not the Stand-by hours). The actual value of the timer is displayed in SDM and CSM in a decimal value. Every two soft-resets increase the hour by +1. Software Identification, Version, and Cluster The software ID, version, and cluster will be shown in the main menu display of SDM, SAM, and CSM. The screen will show: AAAABCD X.YY, where: AAAA is the chassis name: LC71 for analogue range (nonDVB), LC72 for digital range (DVB). B is the region indication: E= Europe, A= AP/China, U= NAFTA, L= LATAM. C is the display indication: L= LCD, P= Plasma. D is the language/feature indication: 1= standard, H= 1080p full HD. X is the main version number: this is updated with a major change of specification (incompatible with the previous software version). Numbering will go from 1 - 9 and A - Z. If the main version number changes, the new version number is written in the NVM. If the main version number changes, the default settings are loaded. YY is the sub version number: this is updated with a minor change (backwards compatible with the previous versions) Numbering will go from 00 - 99. If the sub version number changes, the new version number is written in the NVM. If the NVM is fresh, the software identification, version, and cluster will be written to NVM. Display Option Code Selection When after an SSB or display exchange, the display option code is not set properly, it will result in a TV with no display. Therefore, it is required to set this display option code after such a repair. To do so, press the following key sequence on a standard RC transmitter: 062598 directly followed by MENU and xxx, where xxx is a 3 digit decimal value of the panel type: see column Panel Code in table Option Codes OP1...OP7 (ch. 8), or see sticker on the side/bottom of the cabinet. When the value is accepted and stored in NVM, the set will switch to Stand-by, to indicate that the process has been completed.

5.1

Test PointsIn the chassis schematics and layout overviews, the test points (Fxxx) are mentioned. In the schematics, test points are indicated with a rectangular box around 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: Colour bar signal. Audio: 3 kHz left, 1 kHz right.

5.2

Service ModesThe Service Mode feature is split into four parts: Service Default Mode (SDM). Service Alignment Mode (SAM). Customer Service Mode (CSM) and Digital Customer Service Mode (DCSM). 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 was 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 (D)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).

OP: Used to read-out the option bytes. See Options in the Alignments section for a detailed description. Seven codes are possible. How to Navigate As this mode is read only, there is not much to navigate. To switch to other modes, use one of the following methods: Command MENU from the user remote will enter the normal user menu (brightness, contrast, colour, etc...) with SDM OSD remaining, and pressing MENU key again will return to the last status of SDM again. To prevent the OSD from interfering with measurements in SDM, command OSD (STATUS for NAFTA and LATAM) from the user remote will toggle the OSD on/off with SDM OSD remaining always on. Press the following key sequence on the remote control transmitter: 062596 directly followed by the OSD/i+ button to switch to SAM (do not allow the display to time out between entries while keying the sequence). How to Exit Switch the set to STANDBY by pressing the mains button on the remote control transmitter or on the television set. If you switch the television set off by removing the mains (i.e., unplugging the television), the television set will remain in SDM when mains is re-applied, and the error buffer is not cleared. The error buffer will only be cleared when the clear command is used in the SAM menu. Note: If the TV is switched off by a power interrupt while in SDM, the TV will show up in the last status of SDM menu as soon as the power is supplied again. The error buffer will not be cleared. In case the set is in Factory mode by accident (with F displayed on screen), by pressing and hold VOL- and CH- together should leave Factory mode.

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 favourite, 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 To activate SDM, use one of the following methods: Press the following key sequence on the remote control transmitter: 062596 directly followed by the MENU button (do not allow the display to time out between entries while keying the sequence).

Error CodesIntroduction Error codes are required to indicate failures in the TV set. In principle a unique error code is available for every: Activated protection. Failing I2C device. General I2C error. SDRAM failure. The last five errors, stored in the NVM, are shown in the Service menus. This is called the error buffer. The error code buffer contains all errors detected 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 displayed at the left side and all other errors shift one position to the right. An error will be added to the buffer if this error differs from any error in the buffer. The last found error is displayed on the left. An error with a designated error code may never lead to a deadlock situation. This means that it must always be diagnosable (e.g. error buffer via OSD or blinking LED procedure, ComPair to read from the NVM). In case a failure identified by an error code automatically results in other error codes (cause and effect), only the error code of the MAIN failure is displayed. Example: In case of a failure of the I2C bus (CAUSE), the error code for a General I2C failure and Protection errors is displayed. The error codes for the single devices (EFFECT) is not displayed. All error codes are stored in the same error buffer (TVs NVM) except when the NVM itself is defective.

5.4.3

Error Codes In case of non-intermittent faults, write down the errors present in the error buffer and clear the error buffer before you begin the repair. This ensures 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 and not the actual cause of the problem (for example, a fault in the protection detection circuitry can also lead to a protection). 5.4.4 Notes 1. Some of the error codes reported are depending on the option code configurations. 2. This error means: no I2C device is responding to the particular I2C bus. Possible causes: SCL/SDA shorted to GND, SCL shorted to SDA, or SCL/SDA open (at uP pin). The internal bus of the Trident platform should not cause the entire system to halt as such an error can be reported. How to Clear the Error Buffer The error code buffer is cleared in the following cases: By using the CLEAR command in the SAM menu: To enter SAM, press the following key sequence on the remote control transmitter: 062596 directly followed by the OSD/i+ button (do not allow the display to time out between entries while keying the sequence). Make sure the menu item CLEAR is selected. Use the MENU UP/DOWN buttons, if necessary. Press the MENU RIGHT button to clear the error buffer. The text on the right side of the CLEAR line will change from CLEAR? to CLEARED If the contents of the error buffer have not changed for 50 hours, the error buffer resets automatically.

Service Modes, Error Codes, and Fault Finding 5.6 Software UpgradingIn this chassis, three SW stacks are used: TV mains SW (processor and processor NVM). Digital TV SW (IBO Zapper). 5.6.1 TV Main SW Upgrade For instructions on how to upgrade the TV Main software, refer to ComPair. 5.6.2 Digital TV Software Upgrade How to Upgrade Philips Digital TV Software (IBO Zapper): Preparation of the Memory Device for Software Upgrade For the procedure you will require: 1. A personal computer with web browsing capability. 2. An archive utility that supports the ZIP-format (e.g. Winzip for Windows). 3. A CompactFlash PC Card Adapter (Type II). 4. A CompactFlash (Type I) portable memory card for insertion into the PC Card Adapter. Philips recommends using Compact Flash (CF) portable memory cards with their respective PC Card Adapters (Sandisk or Kingston) with memory sizes of up to 256MB. Philips does not guarantee that other types of portable memory cards and their respective PC Card Adapters, including multi-card PC Card Adapters work on Philips Digital TV. Note: Only FAT16-formatted portable memory is supported. NTFS & FAT32 are not supported. Copying of Software Image Files to the Flash Device Copy the appropriate FCL.img and IBOZ.img to the root directory of the flash device. Verifying the Current Version of the TV Software Before you start the software upgrade procedure, it is advised to check what the current TV software is. The current TV software version can be seen in the System software menu. 1. First press the A/D key and then the DIGITAL MENU key on the remote controller to access the Setup menu. 2. Access the Information menu. 3. Access the Current software version menu. Example: The menu shows IdtvZapper_HW260.256_SW2.0.24. This means that the hardware version is 260.256 and the software version is 2.0.24.

Note: If you exit SAM by disconnecting the mains from the television set, the error buffer is not reset.

5.55.5.1

The Blinking LED ProcedureIntroduction 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 colour. 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 SDMmode 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. To erase the error buffer, the RC command MUTE 062599 OK can be used.

Warnings: Do NOT remove the memory card or the PC card adapter during the software upgrade procedure. In case of a power drop during the upgrade procedure, dont remove the portable memory from the TV. The TV will continue the upgrade as soon as the power comes back. Example: At start-up of the TV, the current software is erased.

Figure 5-15 Upgrade ready When the software upgrade has been successful, switch OFF the TV, remove the PC Card Adapter, and restart the TV with the Power switch at the side of the TV. The TV will now start up with the new software. Verifying that the Software Has Been Upgraded Successfully Verify that the software is upgraded to the new version by following the procedure outlined in the section Verifying the current version of the TV software.

Figure 5-14 Programming complete The TV will reset and the screen will go blank, after a few seconds a dialogue box will occur to inform you that the current module inserted in the CI slot is not recognized. This is normal as the slot only recognizes a Conditional Access Module during normal operation. Example: The following dialogue box will appear after the TV is upgraded successfully:

Service Modes, Error Codes, and Fault FindingAlternative method (1): 1. Go to SAM. 2. Select NVM Editor. 3. Select ADR (address) to 1 (dec). 4. Change the VAL (value) to 170 (dec). 5. Store the value. 6. Do a hard reset to make sure new default values took place. Alternative method (2): It is also possible to upload the default values to the NVM with ComPair in case the SW is changed, the NVM is replaced with a new (empty) one, or when the NVM content is corrupted. After replacing an EEPROM (or with a defective/no EEPROM), default settings should be used to enable the set to start-up and allow the Service Default Mode and Service Alignment Mode to be accessed. 5.7.3 Start-up/Shut-down Flowcharts Important note for DVB sets: When you put a DVB set into Stand-by mode with an RC, the set will go to Semi Stand-by mode for 5 minutes. This, to facilitate Off the Air download (OAD). If there is no activity within these 5 minutes, the set will switch to Standby mode. In Semi Stand-by mode, the LCD backlight and Audio Amplifier are turned off but other circuits still work as normal. The customer might think the set is in Stand-by. However, in real Stand-by mode, only the uP and the NVM are alive and all other circuits are switched off. If you press the mains switch at the local key board in a DVB set, the set will switch to Stand-by mode. On the next pages you will find start-up and shut-down flowcharts, which might be helpful during fault finding. Please note that some events are only related to PDP sets, and therefore not applicable to this LCD chassis.

Fault Finding and Repair TipsNotes: 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.

5.7.1

NVM Editor In some cases, it can be convenient if one directly can change the NVM contents. This can be done with the NVM Editor in SAM mode. With this option, single bytes can be changed. Caution: Do not change the NVM settings without understanding the function of each setting, because incorrect NVM settings may seriously hamper the correct functioning of the TV set! Always write down the existing NVM settings, before changing the settings. This will enable you to return to the original settings, if the new settings turn out to be incorrect. Table 5-3 NVM editor overviewHex .ADR .VAL .Store 0x000A 0x0000 Store? Dec 10 0 Description Existing value New value

5.7.2

Load Default NVM Values It is possible to download default values automatically into the NVM in case a blank NVM is placed or when the NVM first 20 address contents are "FF". After the default values are downloaded, it is possible to start-up and to start aligning the TV set. To initiate a forced default download the following action has to be performed: 1. Switch off the TV set with the mains cord disconnected from the wall outlet (it does not matter if this is from "Standby" or "Off" situation). 2. Short-circuit the SDM jumpers on the SSB (keep short circuited). 3. Press P+ or CH+ on the local keyboard (and keep it pressed). 4. Reconnect the mains supply to the wall outlet. 5. Release the P+ or CH+ when the set is on or blue LED is blinking. When the downloading has completed successfully, the set should be into Stand-by, i.e. red LED on.
