Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard. Wear safety goggles when you replace the CRT. Safety regulations require that after a repair, the set must be returned in its original condition. Pay in particular attention to the following points: General repair instruction: as a strict precaution, we advise you to re-solder the solder connections through which the horizontal deflection current flows. In particular this is valid for the: 1. Pins of the line output transformer (LOT). 2. Fly-back capacitor(s). 3. S-correction capacitor(s). 4. Line output transistor. 5. Pins of the connector with wires to the deflection coil. 6. Other components through which the deflection current flows. Note: This re-soldering is advised to prevent bad connections due to metal fatigue in solder connections, and is therefore only necessary for television sets more than two years old. Route the wire trees and EHT cable correctly and secure 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, to prevent the cord from touching the CRT, hot components, or heat sinks. 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

Warnings In order to prevent damage to ICs and transistors, avoid all high voltage flashovers. In order to prevent damage to the picture tube, use the method shown in figure Discharge picture tube, to discharge the picture tube. Use a high voltage probe and a multi-meter (position VDC). Discharge until the meter reading is 0 V (after approx. 30 s).

V

E_06532_007.eps 250304

Figure 2-1 Discharge picture tube 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 prevents circuits from becoming unstable.

2.42.4.1

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 Service Default Mode (see chapter 5) with a colour bar signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated otherwise) and picture carrier at 475.25 MHz for PAL, or 61.25 MHz for NTSC (channel 3). Where necessary, measure the waveforms and voltages with (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. The semiconductors indicated in the circuit diagram and in the parts lists, are interchangeable per position with the

Maintenance InstructionsWe recommend a maintenance inspection carried out by qualified service personnel. The interval depends on the usage conditions: When a customer uses the set under normal circumstances, for example in a living room, the recommended interval is three to five years. When a customer uses the set in an environment with higher dust, grease, or moisture levels, for example in a kitchen, the recommended interval is one year. The maintenance inspection includes the following actions:

2.4.2

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.

2.4.3

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. 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.

Figure 2-3 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 avoid mixed regimes. If this cannot be avoided, carefully clean 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!

Safety Instructions, Warnings, and Notes 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.

EN 7

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. 2.4.5 Alternative BOM identification In September 2003, Philips CE introduced a change in the way the serial number (or production number, see Figure 2-2) 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. 29PT9521/12), 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. 2.4.6 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.

Test PointsThis chassis is equipped with test points in the service printing. In the schematics, test points are identified with a rectangle box around Fxxx or Ixxx. These test points are specifically mentioned in the service manual as half moons with a dot in the centre. The chassis is equipped with test points (Fxxx) printed on the circuit board assemblies. As most signals are digital, it will be almost impossible to measure waveforms with a standard oscilloscope. Therefore, waveforms are not given in this manual. Perform measurements under the following conditions: Television set in Service Default Alignment Mode. Video input: Colour bar signal. Audio input: 3 kHz left channel, 1 kHz right channel.

How to Enter To enter SDM, use one of the following methods: Press the following key sequence on the remote control transmitter: 062596 directly followed by the MENU button (do not allow the OSD display to time out between entries while keying the sequence). Short the SDM contact to mass (see Figure "SDM Service contact") on the TV board and apply AC Power. Remove the short after start-up. Caution: Entering SDM by shorting the "Service" contact to mass will override the software protections. Do this only for a short period. When doing this, the servicetechnician must know exactly what he is doing, as it could damage the television set.

5.2

Service ModesService Default mode (SDM) and Service Alignment Mode (SAM) offer several features for the service technician, while the Customer Service Mode (CSM) and the Digital Customer Service Mode (DCSM, only for TVs with digital reception module) are used for communication between the call centre and the customer. This chassis offers the option of using the IAP Tool (In Application Programming), a hardware interface between a computer and the TV chassis, for software uploading to the TV set.

Customer Service Mode (CSM) Purpose The Customer Service Mode shows error codes and information on the TVs operation settings. The call centre can instruct the customer (by telephone) to enter CSM in order to identify the status of the set. This helps the call centre to diagnose problems and failures in the TV set before making a service call. The CSM is a read-only mode; therefore, modifications are not possible in this mode. How to Enter To enter CSM, press the following key sequence on the remote control transmitter: 123654 (do not allow the OSD display to time out between entries while keying the sequence). Upon entering the Customer Service Mode, the following screen will appear:

How to Order Note: If you encounter any problems, contact your local support desk.

5.55.5.1

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 has occurred, the error is added to the list of errors, provided the list is not full or the error is a protection error. 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 50+ operation hours. When multiple errors occur (errors occurred within a short time span), there is a high probability that there is some relation between them.

Figure 5-6 IAP interface circuit diagram 5.5.3 Installing the IAP software on a PC When all the items mentioned above are present, install the software on a PC as follows: Extract the Trident EXSDK package (EXSDK.zip) into C:\Trident\Bin. The IAPWriter6.exe file is now inside the Bin folder. Programming the Flash IC The pre-requisite for flashing the software is that the Flash IC should have a bootloader (this means that there is already software on the TV set). To start the flashing, do as follows: Turn on the TV set, enter SAM mode > IAP. The TV is now in the IAP mode. Connect the PC to the TV via the Parallel-to-I2C card (IAP Interface). Double-click on C:\Trident\Bin\IAPWriter6.exe in order to launch the IAP writer. The main interface will appear. Check that these parameters are set correctly: DEVICE STM29W400DT MPU Start Address 080000 MPU End Address 0FBFFF Buffer Start Address 000000 Buffer End Address 07FFFF Note: The device depends on the Flash IC used. Select File > Load, and select the .bin file to be programmed to the Flash IC. Select File Type Binary. Select Write Device. Note: If there are no errors reported, the programming is successful. Note: Sometimes, an error message may appear. Please try a few times if this happens. How to Clear the Error Buffer Use one of the following methods: By activation of the CLEAR ERRORS 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 Codes The function of error codes is to indicate failures in the TV set. In principle a unique error code is available for every: I2C device error. I2C bus error (for every bus containing two or more I2C devices). Protection error (e.g. +8V protection or Horizontal protection). Error not related to an I2C device, but of importance (e.g. BC-loop, RAM error).

Service Modes, Error Codes, and Fault Finding5.6.2 How to Activate Use one of the following methods: Activate the SDM (only by shorting the soldering pad indicated in Figure SDM Service contact on the first page of this chapter to mass). The blinking front LED will show the entire contents of the error buffer (this works in normal operation mode and in protection mode). In order to avoid confusion with RC5 signal reception blinking, this LED blinking procedure is terminated when an RC5 command is received. Transmit the commands MUTE, 06250x, and OK with a normal RC (where x is the position in the error buffer that has to be displayed). With x= 1, the last detected error is shown, x= 2 the second last error, etc.... When x= 0, all errors are shown. DIAGNOSE X with the DST (where x is the position in the error buffer that has to be displayed). With x= 1, the last detected error is shown, x= 2 the second last error, etc.... When x= 0, all errors are shown. Note: It can take some seconds before the blinking LED starts.

Software DownloadingIn this chassis, you can upgrade the software via the IAP Tool (In Application Programming). You can find more information on this in the paragraph Service Tools in this chapter.

5.8Service Tips: In case of non-intermittent faults, clear the error buffer before you begin the repair. This to ensure that old error codes are no longer present. Before clearing the buffer, write down the content, as this history can give you significant information. 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).

Fault Finding and Repair TipsNotes: It is assumed that the components are mounted correctly with correct values and no bad solder joints. Before any fault finding actions, check if the correct options are set.

5.8.1

NVM Editor In some cases, it can be handy if one directly can change the NVM contents. This can be done with the NVM Editor in SAM mode. In the next table, the default NVM values are given.

5.65.6.1

The Blinking LED ProcedureIntroduction 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 SDM is activated, the front LED will show (by blinking) the contents of the error-buffer. Error-codes > 10 are shown as follows: 1. A long blink of 750 ms (which is an indication of the decimal digit), 2. A pause of 1500 ms, 3. n short blinks (where n = 1 - 9), 4. When all the error-codes are displayed, the sequence finishes with a LED blink of 3000 ms, 5. The sequence starts again. Example: Error 12 9 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 1500 ms, 2. 2 short blinks of 250 ms, followed by a pause of 3000 ms, 3. 9 short blinks of 250 ms, followed by a pause of 3000 ms, 4. 6 short blinks of 250 ms, followed by a pause of 3000 ms, 5. 1 long blink of 3000 ms to finish the sequence, 6. The sequence starts again.

Note: When aligning a TV set, it is convenient to start with the default settings, and then to change them, if necessary, to customized values. If you suspect a defective TV set is programmed with the wrong settings or options, try to restore the set to its default settings or set the options to their virgin mode (the latter can also be done via the NVM Editor in the SAM menu, see chapter 8 and the table Option codes). If the remote control of a TV set is defective of missing, and you can not enter the CSM or SAM menu, it is always possible to return the TV to its virgin mode by simultaneously pressing the Volume+ and Volume- keys on the Top Control/Side I/O panel of the TV set.
