Power consumption (values are indicative) - Normal operation (W) : 128 (32) : 163 (37) : 248 (42) - Standby (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.

example below it is 2006 week 17). The 6 last digits contain the serial number.MODEL : 32PF9968/10MADE IN BELGIUM 220-240V ~ 50/60Hz 128W VHF+S+H+UHF

PROD.NO: AG 1A0617 000001

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

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

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.

Test PointsThe chassis is equipped with test points (Fxxx) printed on the circuit board assemblies. 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 ModesService Default mode (SDM) and Service Alignment Mode (SAM) offers several features for the service technician, while the Customer Service Mode (CSM) is used for communication between the call centre and the customer. Also a service mode for servicing the AmbiLight units is foreseen. This chassis also offers the option of using ComPair, a hardware interface between a computer and the TV chassis. It offers the abilities of structured troubleshooting, error code reading, and software version read-out for all chassis. Minimum requirements for ComPair: a Pentium processor, a Windows OS, and a CD-ROM drive (see also paragraph "ComPair").

All picture settings at 50% (brightness, colour, contrast). All sound settings at 50%, except volume at 25%. All service-unfriendly modes (if present) are disabled, like: (Sleep) timer. Child/parental lock. Picture mute (blue mute or black mute). Automatic volume levelling (AVL). Auto switch "off" (when no video signal was received for 10 minutes). Skip/blank of non-favourite pre-sets. Smart modes. Auto store of personal presets. Auto user menu time-out.

5.2.1

Service Default Mode (SDM) Purpose To create a pre-defined setting, to get the same measurement results as given in this manual. To override SW protections detected by stand-by processor and make the TV start up to the step just before protection (a sort of automatic stepwise start up). See paragraph Stepwise Start Up. To override SW protections detected by Viper (PNX8550). Depending on the SW version it is possible that this mechanism does not work correctly. See also paragraph Error codes. To start the blinking LED procedure (not valid in protection mode).

How to Activate SDM For DVBT TVs there are two kinds of SDM: an analogue SDM and a digital SDM. Tuning will happen according table SDM Default Settings. Analogue SDM: use the standard RC-transmitter and key in the code 062596, directly followed by the MENU button. Note: It is possible that, together with the SDM, the main menu will appear. To switch it "off", push the MENU button again. Digital SDM: use the standard RC-transmitter and key in the code 062593, directly followed by the MENU button. Depending on the software version it is possible that the tuning will not work correctly. Note: It is possible that, together with the SDM, the main menu will appear. To switch it "off", push the MENU button again. Analogue SDM can also be activated by shorting for a moment the two solder pads [1] on the SSB, with the indication SDM. They are located outside the shielding. Activation can be performed in all modes, except when the set has a problem with the Stand-by Processor. See figure Service mode pads.

How to Navigate When you press the MENU button on the RC transmitter, the set will toggle between the SDM and the normal user menu (with the SDM mode still active in the background). How to Exit SDM Use one of the following methods: Switch the set to STAND-BY via the RC-transmitter. Via a standard customer RC-transmitter: key in 00sequence. 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 SAM Via 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, you can continue by pressing the red button on the RC. Contents of SAM: Hardware Info. A. SW Version. Displays the software version of the VIPER software (main software) (example: BX31E1.2.3.4_12345 = AAAAB_X.Y.W.Z_NNNNN). AAAA= the software name. B= the region: A= AP, E= EU, L= LatAm, U = US. For AP sets it is possible that the Europe software version is used. 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). NNNNN= last five digits of 12nc code of the software. B. SBY PROC 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 maximal 10 errors). The most recent error is displayed at the upper left (for an error explanation see paragraph Error Codes). Defective Module. Here the module that generates the error is displayed. If there are multiple errors in the buffer, which are not all generated by a single module, there is probably another defect. It will then display the message UNKNOWN here. Not all errors will display a defective module name. Reset Error Buffer. When you press cursor right and then the OK button, the error buffer is reset. Alignments. This will activate the ALIGNMENTS submenu. Dealer Options. Extra features for the dealers. Options. Extra features for Service. For more info regarding option codes, see chapter 8. Note that if you change the option code numbers, you have to confirm your changes with the OK button before you store the options. Otherwise you will lose your changes. Initialise NVM. When an NVM was corrupted (or replaced) in the former EMG based chassis, the microprocessor replaces the content with default data (to assure that the set can operate). However, all preferences and alignment values are gone now, and option numbers are not correct. Therefore, this was a very drastic way. In this chassis, the procedure is implemented in another way: The moment the processor recognizes a corrupted NVM, the initialize NVM line will be highlighted. Now, you can do two things (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 (same as in the past, however now it happens conscious).

Note: When you have a corrupted NVM, or you have replaced the NVM, there is a high possibility that you will not have picture any more because your display option is not correct. So, before you can initialize your NVM via the SAM, you need to have picture and therefore you need the correct display option. To adapt this option, you can use ComPair (the correct HEX values for the options can be found in the table below) 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 button and XXX, where XXX is the 3 digit decimal display option code as mentioned in the first column of the next table. The decimal display option code can also be found on a sticker on the rear cover of the set. See figure Display option code for details. Make sure to key in all three digits, also the leading zeros. 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 initialised first (loaded with default values). This initialising can take up to 20 seconds.

The four items are Channel list, Personal settings, Option codes and Display-related alignments. First you have to create a directory repair\ in the root of the USB stick.To upload the settings you have to select each item separately, press cursor right, confirm with OK and wait until Done appears. Now the settings are stored onto your 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 you have picture. This method is created to be able to save the customers TV settings and to store them into another SSB. Download from USB. Here you are able to download several settings from the USB stick to the TV. Same way of working 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. How to Navigate In SAM, you can select the menu items 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 SAM Use one of the following methods: Press the MENU button on the RC-transmitter. Switch the set to STAND-BY via the RC-transmitter.

Customer Service Mode (CSM) Purpose When a customer is having problems with his TV-set, he can call his dealer or the Customer Helpdesk. The service technician can then ask the customer to activate the CSM, in order to identify the status of the set. Now, the service technician can judge the severity of the complaint. In many cases, he can advise the customer how to solve the problem, or he can decide if it is necessary to visit the customer. The CSM is a read only mode; therefore, modifications in this mode are not possible. When in this chassis, CSM is activated, a colour bar test pattern will be visible for 5 seconds. This test pattern is generated by the Pacific3. So if you see this test pattern you can determine that the back end video chain (Pacific3, LVDS and display) is working. Also new in this chassis: when you activate CSM and there is a USB stick connected to the TV, the software will dump the complete CSM content to the USB stick. The file (Csm.txt) will be saved in the root of your USB stick. This info can be handy if you dont have picture. How to Activate CSM Key in the code 123654 via the standard RC transmitter. Note: Activation of the CSM is only possible if there is no (user) menu on the screen! How to Navigate By means of the CURSOR-DOWN/UP knob on the RCtransmitter, you can navigate through the menus. Contents of CSM 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 a possibility to do this. Production Code. Displays the production code (the serial number) of the TV.

Gives the latest five errors of the error buffer. As soon as the built-in diagnose software has detected an error the buffer is adapted. The last occurred error is displayed on the leftmost position. Each error code is displayed as a 2-digit number. When less than 10 errors occur, the rest of the buffer is empty (00). See also paragraph Error Codes for a description. Code 2. Gives the first five errors of the error buffer. See also paragraph Error Codes for a description. Options 1. Gives the option codes of option group 1 as set in SAM (Service Alignment Mode).

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 a possibility to do this. This identification number consists of 14 characters and is built up as follows: - 8 last characters of the 12NC of the SSB itself. - the serial number of the SSB, which consists of 6 digits. Both can be found on a sticker on the PWB of the SSB itself (not on the sticker on the outside of the shielding!). The format of the identification number is then as follows: (total 14 characters).

Service Modes, Error Codes, and Fault FindingWhen the TV is in protection state due to an error detected by main software (Viper protection) and SDM is activated via shortcutting the pins on the SSB, the TV starts up and ignores the error. Due to architectural reasons it is possible that the TV will end up in an undefined state (e.g. when the fast I2C bus is blocked). In this case diagnose has to be done via ComPair. The abbreviations SP and MP in the figures stand for: SP: protection or error detected by the Stand-by Processor. MP: protection or error detected by the VIPER Main Processor. In the next transition diagrams for POD should be read CI.

Stepwise Start-upThe stepwise start-up method, as known from FTL/FTP sets (EMG based sets) is not valid any more. There are two possible situation: one for protections detected by standby software and one for protections detected by main software. When the TV is in a protection state due to an error detected by standby software (and thus blinking an error) and SDM is activated via shortcutting the pins on the SSB, the TV starts up until it reaches the situation just before protection. So, this is a kind of automatic stepwise start-up. In combination with the start-up diagrams below, you can see which supplies are present at a certain moment. Important to know here is, that if e.g. the 3V3 detection fails (and thus error 11 is blinking) and the TV is restarted via SDM, the Stand-by Processor will enable the 3V3, but will not go to protection now. The TV will stay in this situation until it is reset (Mains/AC Power supply interrupted).

action holder: MIPS action holder: St-by autonomous action

Standby Supply starts running. +5V2, 1V2Stb, 3V3Stb and +2V5D become present. In case of PDP 3V3 Vpr to CPU PDP becomes present.

st-by P resets

All I/O lines have a High default state: - Assert the Viper reset. - Sound-Enable and Reset-Audio should remain high. - NVM power line is high, no NVM communication possible.

If the protection state was left by short circuiting the SDM pins, detection of a protection condition during startup will stall the startup. Protection conditions in a playing set will be ignored. The protection mode will not be entered.

Initialise I/O pins of the st-by P, start keyboard scanning, RC detection, P50 decoding. Wake up reasons are off.

- Switch Sound-Enable and Reset-Audio high. They are low in the standby mode if the standby mode lasted longer than 10s.

The audio protection circuit shuts down the supply autonomously. This triggers a set restart and during that restart (so at this check here), it will be observed that the audio protection line is high and the audio protection mode is entered. This condition is not valid for an SDI PDP. In this PDP set, the audio protection latch is not present and hence the HIGH condition here will never be observed. As a result, when an audio protection occurs, the set will restart and will enter a supply protection mode because of a missing power supply.

PDPGO line is high (either HW wise in a non FHP set or because of the stby P reset in a FHP set) which is the good state at cold boot to be able to start the FHP.

Audio Protection Line HIGH?

Yes

Audio Error

No

SPSwitching the POD-MODE low in an FHP PDP set makes the CPUGO go high and starts the PDP CPU. Switching the POD-MODE and the ON-mode low in an SDI PDP set makes the PDP supplies go to the ON mode.

Switching on the power supply in an LPL scanning backlight set, also switches on the backlight supply. The display should not be used the first 5 seconds the backlight supply is running due to a pre-heat time of 4s and a 100% light output (not adjustable) the next second. This 5 second delay does not delay the startup of the display as this time is absorbed in the startup time of the rest of the system.

Switch LOW the NVM power reset line. Add a 2ms delay before trying to address the NVM to allow correct NVM initialization.

Switch ON all supplies by switching LOW the POD-MODE and the ON-MODE I/O lines.

+5V, +8V6, +12VS, +12VSW and Vsound are switched on

Wait 50ms and then start polling the detect5V, detect-8V6 and detect-12V every 40ms.

The availability of the supplies is checked through detect signals (delivered by dedicated detect-IC's) going to the st-by P. These signals are available for +12V, +8V6, +5V, +1V2 and +2V5. A low to high transition of the signals should occur within a certain time after toggling the standby line. If an observers is detected before the time-out elapses, of course, the process should continue in order to minimize start up time.

No detect-5V received within 2900 ms after POD-MODEI/Oline toggle? PDPGO = High?

No

Yes

- Only when the PDPGO is low, a retry should be considered (the PDP could have reset internally). If the PDPGO is already high, there is no use in trying to restart. - PDPGO line is pulled high in all non FHP sets so this extra startup delay in case of a fault condition is not valid. - Switching the PDPGO high will give a visual artefact and should only be done if really necessary.

Semi StandbyThe assumption here is that a fast toggle (SEMI >ON. In these states, the Viper is still active and can provide the 2s delay.

Service ToolsComPair Introduction ComPair (Computer Aided Repair) is a Service tool for Philips Consumer Electronics 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. Specifications ComPair 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). The ComPair fault finding program is able to determine the problem of the defective television, by a combination of automatic diagnostics and an interactive question/answer procedure. How to Connect This is described in the chassis fault finding database in ComPair.TO TVTO I2C SERVICE CONNECTOR TO UART SERVICE CONNECTOR

5.4.2

LVDS Tool Introduction This Service tool (also called ComPair Assistant 1) may help you to identify, in case the TV does not show any picture, whether the Small Signal Board (SSB) or the display of a Flat TV is defective. Thus to determine if LVDS, RGB, and sync signals are okay. When operating, the tool will show a small (scaled) picture on a VGA monitor. Due to a limited memory capacity, it is not possible to increase the size when processing high-resolution LVDS signals (> 1280x960). Below this resolution, or when a DVI monitor is used, the displayed picture will be full size. How to Connect Connections are explained in the user manual, which is packed with the tool. The LVDS cables included in the package cover most chassis. For some chassis, a separate cable must be ordered. Note: To use the LVDS tool, you must have ComPair release 2004-1 (or later) on your PC (engine version >= 2.2.05). For every TV type number and screen size, one must choose the proper settings via ComPair. The ComPair file will be updated regularly with new introduced chassis information.

E.g.: 00 00 00 00 00: No errors detected 06 00 00 00 00: Error code 6 is the last and only detected error 09 06 00 00 00: Error code 6 was first detected and error code 9 is the last detected error Via the blinking LED procedure (when you have no picture). See next paragraph. Via ComPair.

Error CodesIntroduction 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), except when the error is a protection error. 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. Basically there are three kinds of errors: Errors detected by the Stand-by Processor. These errors will always lead to protection and an automatic start of the blinking LED for the concerned error (see paragraph The Blinking LED Procedure). In these cases SDM can be used to start up (see chapter Stepwise Start-up). Note that it can take up to 90 seconds before the TV goes to protection and starts blinking the error (e.g. error 53) Errors detected by VIPER that lead to protection. In this case the TV will go to protection and the front LED should also blink the concerned error. Depending on the software version it is possible that this mechanism does not work. See also paragraph Error Codes -> Error Buffer -> Extra Info. Errors detected by VIPER that do not lead to protection. In this case the error will be logged into the error buffer and can be read out via ComPair, via blinking LED method, or in case you have picture, via SAM.

5.5.3

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.

5.5.4

Error Buffer In case of non-intermittent faults, clear the error buffer before you begin the repair (before clearing the buffer, write down the content, as this history can give you 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). There are several mechanisms of error detection: Via error bits in the status registers of ICs. Via polling on I/O pins going to the stand-by processor. Via sensing of analogue values on the stand-by processor or the Viper. Via a not acknowledge of an I2C communication. Take notice that some errors need more than 90 seconds before they start blinking. So in case of problems, wait 2 minutes from start-up onwards, and then check if the front LED is blinking.

Service Modes, Error Codes, and Fault FindingExtra Info Rebooting. When a TV is constantly rebooting due to internal problems, most of the time no errors will be logged or blinked. This rebooting can be recognised via a ComPair interface and Hyperterminal (for Hyperterminal settings, see paragraph Stand-by software upgrade). You will see that the loggings which are generated by the main software keep continuing. In this case (rebooting) diagnose has to be done via ComPair. Error 1 (I2C bus 1 blocked). Depending on the software version, there are two possibilities: - The TV goes into protection and the front LED will blink error 1. Now you can start up the TV via the SDM short-cut pins on the SSB. The TV will start up and ignores the error. Depending on the problem it is even possible that you have picture. - With this error, probably only the green LED lights up. The TV does not go into protection but error 1 will still be logged in the error buffer. In some cases you can have picture and sound and then you can check the error buffer. Otherwise use ComPair for further diagnosis (e.g. read out the NVM content). Error 2 (I2C bus 2 blocked). Depending on the software version, there are two possibilities: - The TV will not start or will keep rebooting. Due to hardware restriction (I2C-bus 2 is the fast I2C-bus), it will be impossible to start up the VIPER when I2C-bus 2 is blocked. When this error occurs, the TV will not start (but probably you will see the green LED) or will keep rebooting (see Rebooting description on how to recognize). Starting up the TV via the SDM short-cut pins will not work. So it will not be possible to read out error 2 via internal software (although it will be logged). Use ComPair for further diagnose (e.g. read out the NVM content). - The TV will go to standby. Due to occasional Pacific problems, it is possible that the Pacific will block the I2C-bus 2. Therefore it has been decided that the TV has to go to stand-by in all cases of a blocked I2C bus 2. Refer also to error 46 description. Error 3 (I2C bus 3 blocked). There are only three devices on I2C bus 3: VIPER, Stand-by Processor, and NVM. The Stand-by Processor is the detection device of this error, so this error will only occur if the VIPER or the NVM is blocking the bus. This error will also blink when the NVM gives no acknowledge on the I2C bus. Note that if the 12 V supply is missing, the DC/DC supply on the SSB will not work. Therefore the VIPER will not get supplies and could block I2C bus 3. So, a missing 12 V can also lead to an error 3. Error 4 (I2C bus 4 blocked). In this chassis, error 4 is no longer a protection error. Error 5 (VIPER does not boot). This error will point to a severe hardware problem around the VIPER (supplies not OK, VIPER completely dead, I2C link between VIPER and Stand-by Processor broken, etc...). Error 7 (8V6 error). In case of a TV with SDI display you will see error 7 blink in case of an audio protection. So except a problem with the 8V6 itself it is also possible that there is something wrong with the audio part. See also paragraph "Hardware Protections" for this. Error 14 (Audio protection). The detection is done on the audio board itself. Several items are monitored: overvoltage, overcurrent, DC level on the speakers and the audio supply voltages. If one of these items fails, the audioprotection will switch off the main supply. All supplies will drop, the standby processor thinks there is a mains dip, and will reboot. At the beginning of the boot process, the audio-protection line is monitored: if this line is active, the set will go to protection and will blink error 14. Error 27 (PNX2015 HD subsystem part). Diagnosing this error will not be possibly via the normal errorcodes. In case this device can not communicate with the Viper via IC, it will not be possible to initialise the tunnelbus. Hence the software will not be able to start up, and will re-boot constantly. Diagnosing these problems will only be possible via ComPair. In theory it is possible that the error

is logged in the NVM (thats why this error is still mentioned here). Error 29 (AVIP 1). Same remark as for error 27. Error 31 (AVIP 2). Same remark as for error 27. Error 44 (NVM). This error will probably never occur because it is masked by error 3 (I2C bus 3). The detection mechanism for error 3 checks on an I2C acknowledge of the NVM. If NVM gives no acknowledge, the stand-by software assumes that the bus is blocked, the TV goes to protection and error 3 will be blinking. Error 46 (Pacific 3). When this errors occurs the TV will go to stand-by. The reason for this is, when there is an occasional boot problem of the Pacific, it will look like the TV has started up in stand-by mode, and the customer can switch it on again. When there is an actual problem with or around the Pacific the TV will go to stand-by every time you try to start up. So this behaviour is an indication of a Pacific problem. But remind that also a blocked I2C-bus 2 can lead to this behaviour (refer also to error 2 description). Error 53. This error will indicate that the VIPER has started to function (by reading his boot script, if this would have failed, error 5 would blink) but initialization was never completed because of hardware peripheral problems (NAND flash, ...) or software initialization problems. Possible cause could be that there is no valid software loaded (try to upgrade to the latest main software version). Note that it takes 90 seconds before the TV goes to protection in this case. Error 63 (POWER OK). When this error occurs, it means that the POWER-OK line did not became high. This error is only applicable for TVs with a SDI display, a FHP display or a Sharp full HD display. Depending on the software version it is possible that the detection mechanism of this error does not function and that the TV keeps rebooting. Error 64 (Display error). When this error occurs it means that there is a problem with the I2C communication towards the display. Allthough several display types communicate via I2C, this error will only work for TVs with a FHP display.

The Blinking LED ProcedureIntroduction The blinking LED procedure can be split up into two situations: Blinking LED procedure in case of a protection detected by the stand-by processor. In this case the error is automatically blinked. This will be only one error, namely the one that is causing the protection. Therefore, you do not have to do anything special, just read out the blinks. A long blink indicates the decimal digit, a short blink indicates the units. Blinking LED procedure in the on state. Via this procedure, you can make the contents of the error buffer visible via the front LED. This is especially useful for fault finding, when there is no picture. When the blinking LED procedure is activated in the on state, the front LED will show (blink) the contents of the error-buffer. Error-codes > 10 are shown as follows: 1. n long blinks (where n = 1 - 9) indicating decimal digit, 2. A pause of 1.5 s, 3. n short blinks (where n= 1 - 9), 4. A pause of approx. 3 s. 5. When all the error-codes are displayed, the sequence finishes with a LED blink of 3 s, 6. The sequence starts again. Example: Error 12 8 6 0 0. After activation of the SDM, the front LED will show: 1. 1 long blink of 750 ms (which is an indication of the decimal digit) followed by a pause of 1.5 s, 2. 2 short blinks of 250 ms followed by a pause of 3 s, 3. 8 short blinks followed by a pause of 3 s, 4. 6 short blinks followed by a pause of 3 s,

5. 1 long blink of 3 s to finish the sequence, 6. The sequence starts again. 5.6.2 How to Activate Use one of the following methods: Activate the SDM. The blinking front LED will show the entire contents of the error buffer (this works in normal operation mode). Transmit the commands MUTE - 062500 - OK with a normal RC. The complete error buffer is shown. Take notice that it takes some seconds before the blinking LED starts. Transmit the commands MUTE - 06250x - OK with a normal RC (where x is a number between 1 and 5). When x= 1 the last detected error is shown, x= 2 the second last error, etc.... Take notice that it takes some seconds before the blinking LED starts.
