Technical Specifications, Connections, and Chassis Overview

1. Technical Specifications, Connections, and Chassis OverviewIndex of this chapter: 1.1 Technical Specifications 1.2 Connection Overview 1.3 Chassis Overview Notes: Figures can deviate due to the different set executions. Specifications are indicative (subject to change). Power consumption - Normal operation (W) - Stand-by (W) Dimensions (WxHxD cm) Weight (kg) : 450 : 800 VA). Replace safety components, indicated by the symbol h, only by components identical to the original ones. Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard. Safety regulations require that after a repair, the set must be returned in its original condition. Pay in particular attention to the following points: Route the wire trees correctly and fix them with the mounted cable clamps. Check the insulation of the Mains/AC Power lead for external damage. Check the strain relief of the Mains/AC Power cord for proper function. Check the electrical DC resistance between the Mains/AC Power plug and the secondary side (only for sets that have a Mains/AC Power isolated power supply): 1. Unplug the Mains/AC Power cord and connect a wire between the two pins of the Mains/AC Power plug. 2. Set the Mains/AC Power switch to the "on" position (keep the Mains/AC Power cord unplugged!). 3. Measure the resistance value between the pins of the Mains/AC Power plug and the metal shielding of the tuner or the aerial connection on the set. The reading should be between 4.5 Mohm and 12 Mohm. 4. Switch "off" the set, and remove the wire between the two pins of the Mains/AC Power plug. Check the cabinet for defects, to prevent touching of any inner parts by the customer.

2.3.2

Schematic Notes All resistor values are in ohms, and the value multiplier is often used to indicate the decimal point location (e.g. 2K2 indicates 2.2 kohm). Resistor values with no multiplier may be indicated with either an "E" or an "R" (e.g. 220E or 220R indicates 220 ohm). All capacitor values are given in micro-farads (= x10-6), nano-farads (n= x10-9), or pico-farads (p= x10-12). Capacitor values may also use the value multiplier as the decimal point indication (e.g. 2p2 indicates 2.2 pF). An "asterisk" (*) indicates component usage varies. Refer to the diversity tables for the correct values. The correct component values are listed in the Spare Parts List. Therefore, always check this list when there is any doubt.

2.3.3

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.

2.32.3.1

NotesGeneral Measure the voltages and waveforms with regard to the chassis (= tuner) ground (H), or hot ground (I), depending on the tested area of circuitry. The voltages and waveforms shown in the diagrams are indicative. Measure them in the

Safety Instructions, Warnings, and Notes 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).MODEL : 32PF9968/10MADE IN BELGIUM 220-240V ~ 50/60Hz 128W VHF+S+H+UHF

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 avoid mixed regimes. If this cannot be avoided, carefully clear the solder-joint from old tin and re-solder with new tin.

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 faultfinding 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 faultfinding 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 faultfinding 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

5.45.4.1

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 faultfinding 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.

Service Modes, Error Codes, and Fault Finding

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). 5.5.3 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 (>= 1280x768). 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 delivered with the tool. 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. How to Order LVDS tool (incl. two LVDS cables: 31p and 20p): 3122 785 90671. Service Manual LVDS tool: 3122 785 00810. LVDS cable 20p (for Telra 14-inch): 3122 785 90810.

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).

The 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).

Service Modes, Error Codes, and Fault Finding 5.6 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. Example of error buffer: 12 9 6 0 0 After entering SDM, the following occurs: 1 long blink of 5 seconds to start the sequence, 12 short blinks followed by a pause of 1.5 seconds, 9 short blinks followed by a pause of 1.5 seconds, 6 short blinks followed by a pause of 1.5 seconds, 1 long blink of 1.5 seconds to finish the sequence, The sequence starts again with 12 short blinks.

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.

5.7.1

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. 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 functionality of the TV set! Always note down the existing NVM settings, before changing the settings. This will enable you to return to the orgininal settings, if the new settings turn out to be incorrect. Table 5-2 NVM editor overview Hex .ADR .VAL .Store 0x000A 0x0000 Dec 10 0 Store?

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 the SDM jumpers (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.

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.

Video Processing No Power 1. Check +12 V and 3V3 at position 1J02. 2. If no supply, check the connector 1J02. 3. If it 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). 4. If the user menu is not visible, check if the LCD panel backlight is ON. 5. If the backlight is OFF, the problem is in the power supply board or LCD panel. Also check pin 12 (LAMP_ON_OFF) of 1J02. It should be HIGH during normal operation. Note: For faultfinding 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 - LCD 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.

5.7.5

Power Supply In case the power supply does not work, check (apart from the obvious fuse-check) if the oscillators in IC7001 and IC7U01 are working. If not, replace the ICs.
