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

Rework on BGA (Ball Grid Array) ICs General Although (LF)BGA assembly yields are very high, there may still be a requirement for component rework. By rework, we mean the process of removing the component from the PWB and replacing it with a new component. If an (LF)BGA is removed from a PWB, the solder balls of the component are deformed drastically so the removed (LF)BGA has to be discarded. Device Removal As is the case with any component that, is being removed, it is essential when removing an (LF)BGA, that the board, tracks, solder lands, or surrounding components are not damaged. To remove an (LF)BGA, the board must be uniformly heated to a temperature close to the reflow soldering temperature. A uniform temperature reduces the risk of warping the PWB. To do this, we recommend that the board is heated until it is certain that all the joints are molten. Then carefully pull the component off the board with a vacuum nozzle. For the appropriate temperature profiles, see the IC data sheet. Area Preparation When the component has been removed, the vacant IC area must be cleaned before replacing the (LF)BGA. Removing an IC often leaves varying amounts of solder on the mounting lands. This excessive solder can be removed with either a solder sucker or solder wick. The remaining flux can be removed with a brush and cleaning agent. After the board is properly cleaned and inspected, apply flux on the solder lands and on the connection balls of the (LF)BGA. Note: Do not apply solder paste, as this has been shown to result in problems during re-soldering.

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.

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

Safety Instructions, Warnings, and Notesavoid mixed regimes. If this cannot be avoided, carefully clear the solder-joint from old tin and re-solder with new tin. Use only original spare-parts listed in the Service-Manuals. Not listed standard material (commodities) has to be purchased at external companies. Special information for lead-free BGA ICs: these ICs will be delivered in so-called "dry-packaging" to protect the IC against moisture. This packaging may only be opened shortly before it is used (soldered). Otherwise the body of the IC gets "wet" inside and during the heating time the structure of the IC will be destroyed due to high (steam-) pressure inside the body. If the packaging was opened before usage, the IC has to be heated up for some hours (around 90C) for drying (think of ESD-protection!). Do not re-use BGAs at all! For sets produced before 1.1.2005, containing leaded soldering tin and components, all needed spare parts will be available till the end of the service period. For the repair of such sets nothing changes.

Device Replacement The last step in the repair process is to solder the new component on the board. Ideally, the (LF)BGA should be aligned under a microscope or magnifying glass. If this is not possible, try to align the (LF)BGA with any board markers. So as not to damage neighbouring components, it may be necessary to reduce some temperatures and times. More Information 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. 2.3.4 Lead-free Solder Philips CE is producing lead-free sets (PBF) from 1.1.2005 onwards. Identification: The bottom line of a type plate gives a 14-digit serial number. Digits 5 and 6 refer to the production year, digits 7 and 8 refer to production week (in example below it is 1991 week 18).

In case of doubt whether the board is lead-free or not (or with mixed technologies), you can use the following method: Always use the highest temperature to solder, when using SAC305 (see also instructions below). De-solder thoroughly (clean solder joints to avoid mix of two alloys). Caution: For BGA-ICs, you must use the correct temperatureprofile, 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. 2.3.5 Alternative BOM identification In September 2003, Philips CE introduced a change in the way the serial number (or production number, see Figure 2-1) is composed. From this date on, the third digit in the serial number (example: AG2B0335000001) indicates the number of the alternative BOM (Bill of Materials used for producing the specific model of TV set). 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 O.E.M.s. By looking at the third digit of the serial number, the service technician can see if there is more than one type of B.O.M. used in the production of the TV set he is working with. He can then consult the At Your Service Web site, where he can type in the Commercial Type Version Number of the TV set (e.g. 28PW9515/12), after which a screen will appear that gives information about the number of alternative B.O.M.s used. If the third digit of the serial number contains the number 1 (example: AG1B033500001), then there is only one B.O.M. version of the TV set on the market. If the third digit is a 2 (example: AG2B0335000001), then there are two different B.O.M.s. Information about 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. 2.3.6 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.

Figure 2-2 Lead-free logo 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 stabilise 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 stabilised 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. 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

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.

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.

Service Modes, Error Codes, and Fault Findingbe 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).

Figure 5-1 Service mode pads After activating this mode, SDM will appear in the upper right corner of the screen (if you have picture). 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

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). 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.

Service Modes, Error Codes, and Fault FindingHow 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. 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 possibility to do this. Code 1. 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). 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 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). Digital Natural Motion. Gives the last status of the Digital Natural Motion setting, as set by the customer. Possible values are Off, Minimum and Maximum. See DFU on how to change this item. Pixel Plus. Gives the last status of the Pixel Plus setting, as set by the customer. Possible values are On and Off. See DFU on how to change this item. DNR. Gives the last status of the DNR setting, as set by the customer. Possible values are Off, Minimum, Medium and Maximum. See DFU on how to change this item. Noise Figure. Gives the noise ratio for the selected transmitter. This value can vary from 0 (good signal) to 127 (average signal) and to 255 (bad signal). For some software versions, the noise figure will only be valid when Active Control is set to medium or maximum before activating CSM. Noise figure is not applicable for DVBT channels. Headphone Volume. Gives the last status of the headphone volume, as set by the customer. The value can vary from 0 (volume is minimum) to 100 (volume is maximum). See DFU on how to change this item. Dolby. Indicates whether the received transmitter transmits Dolby sound (ON) or not (OFF). Attention: The presence of Dolby can only be tested by the software on the Dolby Signalling bit. If a Dolby transmission is received

Store. All options and alignments are stored when pressing cursor right and then the OK-button SW Maintenance. SW Events. Not useful for Service purposes. In case of specific software problems, the development department can ask for this info. HW Events. Not useful for Service purposes. In case of specific software problems, the development department can ask for this info. Operation hours PDP. Here you are able to reset the operations hours of the plasma display. This has to be done in case of replacement of the display. Upload to USB. Here you are able to upload several settings from the TV to a USB stick which is connected to the Side IO. 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. 5.2.3 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.

Service Modes, Error Codes, and Fault Findingwithout a Dolby Signalling bit, this indicator will show OFF even though a Dolby transmission is received. Surround Mode. Indicates the by the customer selected sound mode (or automatically chosen mode). Possible values are STEREO and VIRTUAL DOLBY SURROUND. It can also have been selected automatically by signalling bits (internal software). See DFU on how to change this item. Audio System. Gives information about the audible audio system.

Service Modes, Error Codes, and Fault FindingWhen 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). When 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.

sided Ambi Light units whereas the single fitted boards are used in sets with 2 sided Ambi Light units. A double fitted board can drive 2 lamp units (6 lamps) and a single fitted board can drive 1 lamp unit (3 lamps). The double fitted boards are supplied by +12Va and +12Vb. The microprocessor is supplied by +12Va. Therefore, if only +12Va is available, lamp unit B will not work. See figure Building blocks of Converter Board for details.Inverters

Figure 5-4 Building blocks of Converter Board The microprocessor performs the following tasks: Dimming of Ambi Light by means of PWM. Translation of I2C-bus commands to PWM. Switches the Ambi Light board to protection if needed (in case of protection only the lamps switch off, no set protection is triggered). There are two ways of protection: parallel arcing protection and serial arcing protection. Parallel arcing protection is performed by sensing the switching frequency. In case of short circuit of the transformer output, this frequency > 100 kHz and the board goes into protection. Serial arcing protection is performed by detection of arc in ground wire of the lamp units. In this case, the protection pulse is transmitted via an opto-coupler. Protection can be disabled by short-circuiting diode 6112 or capacitor 2173 or by connecting pin 8 of the microprocessor to ground. Repair Tips In case only one or no lamp unit at all works, probably the +12Vb (12 - 13 V) is not available or the fuse is broken. Check for broken MOSFETS or check if they are switched off properly by the transistors connected to the PWM outputs of the microprocessor. In case the Ambi Light switches off after two seconds, serial arcing or parallel arcing protection is active. Serial arcing protection can be excluded by disconnecting the opto-coupler; check for bad solder joints on transformer or lamp units. Parallel arcing protection can be disabled by grounding pin 8 of the microprocessor. Usually the switching frequency (normally 63 kHz) will then be too high. Possible causes are one MOSFET of the converter has no gate drive or is broken, or there is a short-circuit of the output of the transformer.

5.3

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.

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. 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.

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

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? - 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.

Service ToolsComPair Introduction ComPair (Computer Aided Repair) is a service tool for Philips Consumer Electronics products. ComPair is a further development on the European DST (service remote control), which allows faster and more accurate diagnostics. ComPair has three big advantages: 1. ComPair helps you to quickly get an understanding on how to repair the chassis in a short time by guiding you systematically through the repair procedures. 2. ComPair allows very detailed diagnostics (on I2C level) and is therefore capable of accurately indicating problem areas. You do not have to know anything about I2C commands yourself because ComPair takes care of this. 3. ComPair speeds up the repair time since it can automatically communicate with the chassis (when the microprocessor is working) and all repair information is directly available. When ComPair is installed together with the Force/SearchMan electronic manual of the defective chassis, schematics and PWBs are only a mouse click away. Specifications ComPair consists of a Windows based fault finding program and an interface box between PC and the (defective) product. The ComPair interface box is connected to the PC via a serial (or RS-232) cable. For this chassis, the ComPair interface box and the TV communicate via a bi-directional service cable via the service connector(s). The ComPair fault finding program is able to determine the problem of the defective television. ComPair can gather diagnostic information in two ways: Automatically (by communicating with the television): ComPair can automatically read out the contents of the entire error buffer. Diagnosis is done on I2C/UART level. ComPair can access the I2C/UART bus of the television. ComPair can send and receive I2C/UART commands to the microcontroller of the television. In this way, it is possible for ComPair to communicate (read and write) to devices on the I2C/UART buses of the TV-set. Manually (by asking questions to you): Automatic diagnosis is only possible if the microcontroller of the television is working correctly and only to a certain extent. When this is not the case, ComPair will guide you through the fault finding tree by asking you questions (e.g. Does the screen give a picture? Click on the correct answer: YES / NO) and showing you examples (e.g. Measure test-point I7 and click on the correct oscillogram you see on the oscilloscope). You can answer by clicking on a link (e.g. text or a waveform picture) that will bring you to the next step in the fault finding process. By a combination of automatic diagnostics and an interactive question / answer procedure, ComPair will enable you to find most problems in a fast and effective way. How to Connect This is described in the chassis fault finding database in ComPair. Caution: It is compulsory to connect the TV to the PC as shown in the picture below (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!TO UART SERVICE CONNECTOR TO I2C SERVICE CONNECTOR
