: 220 : 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.
2.2
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.
2.3.3
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.

Directions for Useworkshops 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 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.
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.

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 the mixing of two alloys). Caution: 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, and 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 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.
Regardless of the special lead-free logo (which is not always indicated), one must treat all sets from this date onwards according to the rules as described below.

If you turn the television set off by removing the mains (i.e., unplugging the television) without using the mains button, the television set will remain in SAM when mains is re-applied, and the error buffer is not cleared. 5.2.3 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 display to time out between entries while keying the sequence). Upon entering the Customer Service Mode, the following screen will appear:

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 micro controller 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 micro controller 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.

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.

Note: If you encounter any problems, contact your local support desk. 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. Furthermore it is possible to program EPLDs with this tool (Byte blaster). Read the user manual for an explanation of this feature. Since 2004, the LVDS output connectors in our Flat TV models are standardised (with some exceptions). With the two delivered LVDS interface cables (31p and 20p) you can cover most chassis (in special cases, an extra cable will be offered). 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. Generally this tool is intended to determine if the SSB is working or not. Thus to determine if LVDS, RGB, and sync signals are okay. How to Connect Connections are explained in the user manual, which is packed with the tool. 5.5.3
Error CodesThe error code buffer contains all errors detected since the last time the buffer was erased. The buffer is written from left to right. When an error occurs that is not yet in the error code buffer, it is displayed at the left side and all other errors shift one position to the right.
5.5.1
How to Read the Error Buffer You can read the error buffer in 3 ways: On screen via the SAM (if you have a picture). Examples: ERROR: 0 0 0 0 0 : No errors detected ERROR: 6 0 0 0 0 : Error code 6 is the last and only detected error ERROR: 9 6 0 0 0 : Error code 6 was detected first and error code 9 is the last detected (newest) error Via the blinking LED procedure (when you have no picture). See The Blinking LED Procedure. Via ComPair.
5.5.2
How to Clear the Error Buffer The error code buffer is cleared in the following cases: By using the CLEAR command in the SAM menu: To enter SAM, press the following key sequence on the remote control transmitter: 062596 directly followed by the OSD/i+ button (do not allow the display to time out between entries while keying the sequence). Make sure the menu item CLEAR is selected. Use the MENU UP/DOWN buttons, if necessary. Press the MENU RIGHT button to clear the error buffer. The text on the right side of the CLEAR line will change from CLEAR? to CLEARED If the contents of the error buffer have not changed for 50 hours, the error buffer resets automatically. Note: If you exit SAM by disconnecting the mains from the television set, the error buffer is not reset. Error Codes In case of non-intermittent faults, write down the errors present in the error buffer and clear the error buffer before you begin the repair. This ensures that old error codes are no longer present. If possible, check the entire contents of the error buffer. In some situations, an error code is only the result of another error and not the actual cause of the problem (for example, a fault in the protection detection circuitry can also lead to a protection).

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. With this option, single bytes can be changed. Caution: Do not change the NVM settings without understanding the function of each setting, because incorrect NVM settings may seriously hamper the correct functioning of the TV set! Do not change the Scaler NVM settings, as this will hamper the DVI / HDMI functionality of the TV set! Always note down the existing NVM settings, before changing the settings. This will enable you to return to the original settings, if the new settings turn out to be incorrect. Table 5-2 NVM editor overview Hex Dec 10 0 Store? Description Existing value New value

Load Default NVM Values In case a blank NVM is placed or when the NVM content is corrupted, default values can be downloaded into the NVM. (For empty NVM replacement, short the SDM with a jumper and apply the mains voltage. Remember to remove the jumper after the reload is completed). After the default values are downloaded, it will be possible to start up and to start aligning the TV set. This is no longer initiated automatically; to initiate the download the following action has to be performed: 1. Switch off the TV set by disconnecting the AC Power plug. 2. Short circuit an SDM jumper (keep short-circuited). 3. Press P+ or Ch+ on the local keyboard (and keep it pressed). 4. Switch on the TV set via the AC Power plug. 5. Keep pressing the P+/Ch+ button until the set has started up and the SDM is shown. Alternative method: 1. Go to SAM. 2. Select NVM Editor (not SC NVM Editor). 3. Select ADR (address) to 1 (dec). 4. Change the VAL (value) to 170 (dec). 5. Store the value. 6. Disconnect the mains plug and wait for a few seconds. 7. Reconnect the mains plug and wait until the set goes into its standby mode (red LED lights up). 8. Restart the set.

The Blinking LED ProcedureUsing this procedure, you can make the contents of the error buffer visible via the front LED. This is especially useful when there is no picture. When the SDM is entered, the front LED will blink the contents of the error-buffer: The LED blinks with as many pulses as the error code number, followed by a time period of 1.5 seconds, in which the LED is off. Then this sequence is repeated. Any RC5 command terminates this sequence.
Service Modes, Error Codes, and Fault Finding5.7.3 Flash New Scaler Software When you need to flash new scaler software, follow the instructions in ComPair. Make sure you put the set in one of the Service Modes, SDM/SAM/CSM, before you start flashing. This reduces the risk of the set hanging during the flashing procedure. 5.7.4 Tuner and IF No Picture in RF Mode, but there is a Noise Raster 1. Check whether picture is present in AV. If not, go to Video processing troubleshooting section. 2. If present, check if the Option settings are correct. 3. Check if all the supply voltages are present (3.3/5/8/12/33 V). 4. Check if the I2C lines are working correctly (3.3 V). 5. Manually store a known channel and check if there is IF output at Tuner pin 11. 6. Check the tuning DC voltage at pin 2 of the Tuner. The DC voltage should vary according to the frequency/channel being chosen. 7. If the tuning voltage is OK, check the tuner output, pin 11. 8. If it has no output, the Tuner may have a defect. Change the Tuner. Sound in Picture Problem for L' System (rolling horizontal lines) 1. Check whether AGC L' in SAM mode is set to 0. 2. If yes, align the set to correct value. Required System is not Selected Correctly Check whether a Service jumper (#4204 & 4205, 0805 size) is present. If yes, remove it. 5.7.5 Video Processing No Power 1. Check +12 V and 3V3 at position 1J02. 2. If no supply, first check the connector 1J02. 3. If the connector is correct, check the power supply board. Power Supply is Correct, but no Green LED 1. Check if the connectors 1K00 are properly inserted. 2. If they are inserted correctly, check if the 3V3 is present. No Picture Display (blank screen with correct sound output) 1. Check whether the user menu is visible. 2. If the user menu is OK, activate teletext mode. 3. If teletext is OK, the problem is in the ADC (B18) & Columbus 3D combfilter (B19), if present (depending on model, see also paragraph Teletext Path in chapter 9). Note: For fault finding purposes, it is important to know the following: in Pixel Plus and Digital Crystal Clear models, which have an ADC (B18) and Columbus 3D combfilter (B19), the digital input of the scaler is used for the digital video path (Hercules output), whereas the analogue RGB input (analogue input of the scaler) is only used for teletext. This means that no mixed mode (video plus teletext simultaneously) is possible. If there is sound and teletext, but no video and user menu (blank screen), the digital path (Hercules - ADC - Columbus - Scaler) is faulty. If there is sound but no teletext, the back-end part (Scaler - PDP panel) is faulty. In Crystal Clear models, which do not have an ADC and Columbus, the RGB path (analogue input of scaler) is used for both video and teletext. No TV, but PC is Present 1. Check if Hsync_SDTV and Vsync_SDTV are present at pin 1 & pin13 of 7E03. 2. If they are present, check teletext output.

3. If there is no teletext output, the IC TDA150xx may be defect. 5.7.6 Power Supply Check Fuse The power supply (various models are used) contains one fuse near the AC input connector X002. 1. Check with power supply in off state by means of ohmic measurement. 2. Fuse X102 may open in case of severe lightning strikes and/or failures in the power supply. 3. Check the standby signal at pin 10 of X200. ON is HIGH, OFF is LOW. During standby mode only the 3V3 is present at pin 10. Protections Concept on Power Supply Board (two models) 1. 12 V output (pin 8 of X200): Short-circuit protected by 2.5 A fuse X610. Over-voltage protection when output voltage is more than 40% above nominal value. 2. Vaudio output (+18 or +24 V, depending on power supply model used); (pin 1 of X200): Short-circuit proof (+18 V version has 2.5 A fuse X660). Over voltage protection when output voltage is more than 40% above nominal value. 3. 3V3STBY output (pin 3&4 of X200): Short-circuit proof with auto-restart. Over voltage protection when output voltage is more than 40% above nominal value. 4. 24 V output (for inverter X520 & X530): Short-circuit proof with auto-restart. Over voltage protection when output voltage is more than 40% above nominal value. Standby Mode 1. Apply a 12 ohm load resistor of sufficient power rating to all outputs mentioned above (+12 V, +18/ 24 V, +3V3 and +24 V). Connect the STBY pin (pin 10 of X200) to logical L (low), i.e. to GND. 2. Over an input voltage range of 90 VAC to 276 VAC only the +3V3 STBY output shall be up. Normal Mode: 1. Apply a 12 ohm load resistor of sufficient power rating to all outputs mentioned above (+12 V, +18/ 24 V, +3V3 and +24 V). Connect the STBY pin (pin 10 of X200) to logical H (high), i.e. to the +3V3 STBY output via a 2,2 k pull up resistor. 2. Over an input voltage range of 90 VAC to 276 VAC all outputs shall be up. The voltage on the +3V3 STBY output shall be 3.3 V over the entire input voltage range. The voltage on the big 400 V capacitor on the power supply should also be 400 V 10%.
