Where necessary, measure the waveforms and voltages with (D) and without (E) aerial signal. Measure the voltages in the power supply section both in normal operation (G) and in stand-by (F). These values are indicated by means of the appropriate symbols.
3.1
Safety Instructions
Safety regulations require the following during a repair: · Connect the set to the Mains/AC Power via an isolation transformer (> 800 VA). · Replace safety components, indicated by the symbol 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. Of de set ontploft! Safety regulations require that after a repair, the set must be returned in its original condition. Pay in particular attention to the following points: · Route the wire trees correctly and fix them with the mounted cable clamps. · Check the insulation of the Mains/AC Power lead for external damage. · Check the strain relief of the Mains/AC Power cord for proper function. · Check the electrical DC resistance between the Mains/AC Power plug and the secondary side (only for sets that have a Mains/AC Power isolated power supply): 1. Unplug the Mains/AC Power cord and connect a wire between the two pins of the Mains/AC Power plug. 2. Set the Mains/AC Power switch to the "on" position (keep the Mains/AC Power cord unplugged!). 3. Measure the resistance value between the pins of the Mains/AC Power plug and the metal shielding of the tuner or the aerial connection on the set. The reading should be between 4.5 M and 12 M. 4. Switch "off" the set, and remove the wire between the two pins of the Mains/AC Power plug. · Check the cabinet for defects, to prevent touching of any inner parts by the customer. 3.3.2
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 k). Resistor values with no multiplier may be indicated with either an "E" or an "R" (e.g. 220E or 220R indicates 220 ). All capacitor values are given in micro-farads ( = × 10-6), nano-farads (n = × 10-9), or pico-farads (p = × 10-12). Capacitor values may also use the value multiplier as the decimal point indication (e.g. 2p2 indicates 2.2 pF). An "asterisk" (*) indicates component usage varies. Refer to the diversity tables for the correct values. The correct component values are listed on the Philips Spare Parts Web Portal.

BGA (Ball Grid Array) ICs Introduction For more information on how to handle BGA devices, visit this URL: http://www.atyourservice-magazine.com. Select "Magazine", then go to "Repair downloads". Here you will find Information on how to deal with BGA-ICs. BGA Temperature Profiles For BGA-ICs, you must use the correct temperature-profile. Where applicable and available, this profile is added to the IC Data Sheet information section in this manual.
3.2
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. Be careful during measurements in the high voltage section. Never replace modules or other components while the unit is switched "on". When you align the set, use plastic rather than metal tools. This will prevent any short circuits and the danger of a circuit becoming unstable.
3.3.5
Lead-free Soldering Due to lead-free technology some rules have to be respected by the workshop during a repair: · Use only lead-free soldering tin. If lead-free solder paste is required, please contact the manufacturer of your soldering equipment. In general, use of solder paste within workshops should be avoided because paste is not easy to store and to handle. · Use only adequate solder tools applicable for lead-free soldering tin. The solder tool must be able: To reach a solder-tip temperature of at least 400°C. To stabilize the adjusted temperature at the solder-tip. To exchange solder-tips for different applications. · Adjust your solder tool so that a temperature of around 360°C - 380°C is reached and stabilized at the solder joint. Heating time of the solder-joint should not exceed ~ 4 sec. Avoid temperatures above 400°C, otherwise wear-out of tips will increase drastically and flux-fluid will be destroyed. To avoid wear-out of tips, switch "off" unused equipment or reduce heat. · Mix of lead-free soldering tin/parts with leaded soldering tin/parts is possible but PHILIPS recommends strongly to avoid mixed regimes. If this cannot be avoided, carefully clear the solder-joint from old tin and re-solder with new tin.

Alternative BOM identification It should be noted that on the European Service website, "Alternative BOM" is referred to as "Design variant". The third digit in the serial number (example: AG2B0335000001) indicates the number of the alternative B.O.M. (Bill Of Materials) that has been used for producing the specific TV set. In general, it is possible that the same TV model on the market is produced with e.g. two different types of displays, coming from two different suppliers. This will then result in sets which have the same CTN (Commercial Type Number; e.g. 28PW9515/12) but which have a different B.O.M. number. By looking at the third digit of the serial number, one can identify which B.O.M. is used for the TV set he is working with. If the third digit of the serial number contains the number "1" (example: AG1B033500001), then the TV set has been manufactured according to B.O.M. number 1. If the third digit is a "2" (example: AG2B0335000001), then the set has been produced according to B.O.M. no. 2. This is important for ordering the correct spare parts! For the third digit, the numbers 1...9 and the characters A...Z can be used, so in total: 9 plus 26= 35 different B.O.M.s can be indicated by the third digit of the serial number. Identification: The bottom line of a type plate gives a 14-digit serial number. Digits 1 and 2 refer to the production centre (e.g. AG is Bruges), digit 3 refers to the B.O.M. code, digit 4 refers to the Service version change code, digits 5 and 6 refer to the production year, and digits 7 and 8 refer to production week (in example below it is 2006 week 17). The 6 last digits contain the serial number.

Figure 3-1 Serial number (example) 3.3.7 Board Level Repair (BLR) or Component Level Repair (CLR) If a board is defective, consult your repair procedure to decide if the board has to be exchanged or if it should be repaired on component level. If your repair procedure says the board should be exchanged completely, do not solder on the defective board. Otherwise, it cannot be returned to the O.E.M. supplier for back charging! 3.3.8 Practical Service Precautions · It makes sense to avoid exposure to electrical shock. While some sources are expected to have a possible dangerous impact, others of quite high potential are of limited current and are sometimes held in less regard. Always respect voltages. While some may not be dangerous in themselves, they can cause unexpected reactions that are best avoided. Before reaching into a powered TV set, it is best to test the high voltage insulation. It is easy to do, and is a good service precaution. B-TXT C CEC

Test Points
As most signals are digital, it will be difficult to measure waveforms with a standard oscilloscope. However, 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.
How to Activate SDM For this chassis there are two kinds of SDM: an analog SDM and a digital SDM. Tuning will happen according to Table 5-1. · Analog SDM: use the standard RC-transmitter and key in the code "062596", directly followed by the "MENU" (or HOME) button. Note: It is possible that, together with the SDM, the main menu will appear. To switch it "off", push the "MENU" (or HOME) button again. · Digital SDM: use the standard RC-transmitter and key in the code "062593", directly followed by the "MENU" (or HOME) button. Note: It is possible that, together with the SDM, the main menu will appear. To switch it "off", push the "MENU" (or HOME) button again. · Analog SDM can also be activated by, on the SSB, shorting for a moment the solder pads SDM [1] (see Figure 5-1).
5.2
Service Modes
Service 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. 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. (see also section 5.4.1 ComPair). Note: For the new model range, a new remote control (RC) is used with some renamed buttons. This has an impact on the activation of the Service modes. For instance the old "MENU" button is now called "HOME" (or is indicated by a "house" icon).

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" or "I+" button. After activating SAM with this method a service warning will appear on the screen, continue by pressing the red button on the RC. Contents of SAM (see also Table 6-4): · Hardware Information A. SW Version. Displays the software version of the main software (example: Q5431-0.26.2.0= AAAaB_X.Y.W.Z). · AAAA= the chassis name, where "a" indicates the chip version: e.g. TV543/32= Q543, TV543/82= Q548, Q543/92= Q549. · B= the SW branch version. This is a sequential number (this is no longer the region indication, as the software is now multi-region). · X.Y.W.Z= the software version, where X is the main version number (different numbers are not compatible with one another) and Y.W.Z is the sub version number (a higher number is always compatible with a lower number). B. 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 maximum 10 errors). The most recent error is displayed at the upper left (for an error explanation see section 5.5 Error Codes). · Reset Error Buffer. When "cursor right" (or the "OK button) is pressed and then the "OK" button is pressed, the error buffer is reset. · Alignments. This will activate the "ALIGNMENTS" submenu. See chapter 6. Alignments. · Dealer Options. Extra features for the dealers. See Table 6-4. · Options. Extra features for Service. For more information regarding option codes, see chapter 6. Alignments. Note that if the option code numbers are changed, these have to be confirmed with pressing the "OK" button before the options are stored. Otherwise changes will be lost. · Initialize NVM. The moment the processor recognizes a corrupted NVM, the "initialize NVM" line will be highlighted. Now, two things can be done (dependent of the service instructions at that moment): Save the content of the NVM via ComPair for development analysis, before initializing. This will give the Service department an extra possibility for diagnosis (e.g. when Development asks for this). Initialize the NVM. · Note: When the NVM is corrupted, or replaced, there is a high possibility that no picture appears because the display code is not correct. So, before initializing the NVM via the SAM, a picture is necessary and therefore the correct display option has to be entered. Refer to chapter 6. Alignments for details. To adapt this option, it's advised to use ComPair (the correct HEX values

for the options can be found in chapter 8 "Alignments") or a method via a standard RC (described below). Changing the display option via a standard RC: Key in the code "062598" directly followed by the "MENU" (or HOME) button and "XXX" (where XXX is the 3 digit decimal display code as mentioned in Table 6-3. Make sure to key in all three digits, also the leading zero's. If the above action is successful, the front LED will go out as an indication that the RC sequence was correct. After the display option is changed in the NVM, the TV will go to the Stand-by mode. If the NVM was corrupted or empty before this action, it will be initialized first (loaded with default values). This initializing can take up to 20 seconds.

How to Exit SAM Use one of the following methods: · Switch the set to STAND-BY via the RC-transmitter. · Via a standard RC-transmitter, key in "00" sequence, or select the "BACK" key. 5.2.3 Customer Service Mode (CSM) 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 CSM is activated, the layer 1 error is displayed via blinking LED. Only the latest error is displayed. (see also section 5.5 Error Codes). When CSM is activated 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 the USB stick. This information can be handy if no information is displayed. Only for Q548.1: When in the Q548.1 chassis CSM is activated, a test pattern will be displayed during 5 s.: 1 s. blue, 1 s. green, and 1 s. red, then again 1 s. blue and 1 s. green. This test pattern is generated by the PNX5100. So if this test pattern is shown, it could be determined that the back end video chain (PNX5100, LVDS, and display) of the SSB is working. For LED backlight TV sets, the test pattern is build as follows: 1 s. blue, 1 s. green, 1 s. red (generated by the PNX5100) and further on with 3 seconds RGB pattern from the LED Dimming Panel. 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 (or the scroll wheel) on the RC-transmitter, can be navigated through the menus. Contents of CSM The contents are displayed on three pages: General, Software versions, and Quality items. However, these group names itself are not shown anywhere in the CSM menu. General · Set Type. This information is very helpful for a helpdesk/ workshop as reference for further diagnosis. In this way, it is not necessary for the customer to look at the rear of the TV-set. Note that if an NVM is replaced or is initialized after corruption, this set type has to be re-written to NVM. ComPair will foresee in a possibility to do this.

Service Modes, Error Codes, and Fault Finding 5.3 Step by step Start-up
When the TV is in a protection state due to an error detected by stand-by software (error blinking is displayed) and SDM is activated via short cutting the pins on the SSB, the TV starts up until it reaches the situation just before protection. So, this is a kind of automatic step by step start-up. In combination with the start-up diagrams below, it is shown which supplies are present at a certain moment. Important to know is, that if e.g. the 3V3 detection fails and thus layer 2 error = 18 is blinking while the TV is restarted via SDM, the Stand-by Processor will enable the 3V3, but the TV set will not go to protection now. The TV will stay in this situation until it is reset (Mains/AC Power supply interrupted).

EN 17
Caution: in case the start-up in this mode with a faulty FET 7101-1 is done, all ICs supplied by the +3V3 could be destroyed, due to over voltage (12V on 3V3-line). It is recommended to measure first the FET 7101-1 or others FETs on short-circuit before activating SDM via the service pads.
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 MIPS Main Processor.

Yes yes Blink Code as error code MIPS sends display parameters and Bitmap to 5100 No To keep this flowchart readable, the exact display turn on description is not copied here. Please see the Semi-standby to On description for the detailed display startup sequence. During the complete display time of the Startup screen, the preheat condition of 100% PWM is valid. The first time after the option turn on of the startup screen or when the set is virgin, the cfg file is not present and hence the startup screen will not be shown. Startup screen shall only be visible when there is a coldboot to an active state end situation. The startup screen shall not be visible when waking up for reboot reasons or waking up to semi-standby conditions.

Initialize audio In case of a LED backlight display, a LED DIM panel is present which is fed by the Vdisplay. To power the LED DIM Panel, the Vdisplay switch driven by the PNX5100 must be closed. The display startup sequence is taken care of by the LED DIM panel. Secondly, this cmd will also enable the LVDS output of the 5100 towards the LED DIM panel. In case of a LED backlight display, the PWM-dimming signal needs to be routed to the LVDS cable. This routing is not allowed in non-LED sets (see also display configuration)
Switch on the display in case of a LED backlight display by sending the TurnOnDisplay(1) (I˛C) command to the PNX5100
Enable the PWM output towards the display LVDS cable in case of a LED Backlight set. (CTRL4-PNX5100)

Service Modes, Error Codes, and Fault Finding
Constraints taken into account:
- Display may only be started when valid LVDS output clock can be delivered by the AVC. - To have a reliable operation of the backlight, the backlight should be driven with a PWM duty cycle of 100% during the first seconds. Only after this first one or two seconds, the PWM may be set to the required output level (Note that the PWM output should be present before the backlight is switched on). To minimize the artefacts, the picture should only be unblanked after these first seconds.
Semi Standby
The assumption here is that a fast toggle (<2s) can only happen during ON->SEMI ->ON. In these states, the AVC is still active and can provide the 2s delay. A transition ON->SEMI->STBY->SEMI->ON cannot be made in less than 2s, because the standby state will be maintained for at least 4s. Wait until previous on-state is left more than 2 seconds ago. (to prevent LCD display problems)
CPipe already generates a valid output clock in the semi-standby state: display startup can start immediately when leaving the semi-standby state.

Wait x ms
Switch on LVDS output in 8543
Delay Lamp-on with the sum of the LVDS delay and the Lamp delay indicated in the display file
The sum of the LVDS delay and the Lamp delay needs to be used because the Lamp delay is specified with the appearance of the LVDS on the display as reference. This moment is not known by ceplf, only the switch on of the LCD power is known. The delta between both is the LVDS delay.
Switch off the dimming backlight feature, set the BOOST control to nominal and make sure PWM output is set to 100%

Release audio mute and wait 100ms before any other audio handling is done (e.g. volume change)
The higher level requirement is that audio and video should be demuted without transient effects and that the audio should be demuted maximum 1s before or at the same time as the unblanking of the video.
Restore dimming backlight feature, PWM and BOOST output and unblank the video.
Switch on the Ambilight functionality according the last status settings. The higher level requirement is that the ambilight functionality may not be switched on before the backlight is turned on in case the set contains a CE IPB inverter supply.

Service Tools
ComPair Introduction ComPair (Computer Aided Repair) is a Service tool for Philips Consumer Electronics products. and offers the following: 1. ComPair helps 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. No knowledge on I2C or UART commands is necessary, 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 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.

Error Codes
Introduction The error code buffer contains all detected errors since the last time the buffer was erased. The buffer is written from left to right, new errors are logged at the left side, and all other errors shift one position to the right. When an error occurs, it is added to the list of errors, provided the list is not full. When an error occurs and the error buffer is full, t
