Safety Instructions, Warnings, and Notes
2. Safety Instructions, Warnings, and Notes
2.1 Safety Instructions
Safety regulations require that 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. 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 which 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 avoid touching of any inner parts by the customer. · 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 standby (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 semiconductors in the unit, irrespective of the type indication on these semiconductors. Manufactured under license from Dolby Laboratories. "Dolby", "Pro Logic" and the "double-D symbol", are trademarks of Dolby Laboratories.

E_06532_006.eps 240604
Figure 2-1 Dolby PL Symbol 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 (µ= 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 Electrical Replacement 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, it is essential when removing an (LF)BGA, 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 chance 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.

2.3.1
Notes
General · 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).
Safety Instructions, Warnings, and Notes
Note: Do not apply solder paste, as this has 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. To reflow the solder, apply a temperature profile according to the IC data sheet. 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 "Workshop Information". Here you will find Information on how to deal with BGA-ICs. 2.3.4 Lead Free Solder Some PWBs in this chassis are "lead-free prepared". This is indicated on the PWB by the PHILIPS lead-free logo (either by a service-printing or by a sticker). It does not mean that leadfree solder is actually used!

Figure 2-2 Lead-free logo Due to this fact, 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. · Use only adequate solder tools applicable for lead-free soldering tin. · Adjust your solder tool so that a temperature around 217 220 deg. C is reached at the solder joint. · Do not mix lead-free soldering tin with leaded soldering tin; this will lead to unreliable solder joints! · Use only original spare parts listed in this manual. These are lead-free parts! · On the website www.atyourservice.ce.philips.com (needs subscription, not available for all regions) you can find more information on: Aspects of lead-free technology. BGA (de-)soldering, heating-profiles of BGAs used in Philips sets, and others. 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 - 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.

Service Modes, Error Codes, and Fault Finding
5.4.2 Specifications ComPair consists of a Windows based faultfinding program and an interface box between PC and the (defective) product. The ComPair interface box is connected to the PC via a serial or RS232 cable. For this chassis, the ComPair interface box and the TV communicate via a bi-directional service cable via the service connector. The ComPair faultfinding program is able to determine the problem of the defective television. ComPair can gather diagnostic information in two ways: · Automatic (by communication with the television): ComPair can automatically read out the contents of the entire error buffer. Diagnosis is done on I2C level. ComPair can access the I2C bus of the television. ComPair can send and receive I2C 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 busses 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 extends. 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. Beside fault finding, ComPair provides some additional features like: · Up- or downloading of pre-sets. · Managing of pre-set lists. · Emulation of the Dealer Service Tool (DST). · If both ComPair and SearchMan (Electronic Service Manual) are installed, all the schematics and the PWBs of the set are available by clicking on the appropriate hyperlink. Example: Measure the DC-voltage on capacitor C2568 (Schematic/Panel) at the Mono-carrier. Click on the "Panel" hyperlink to automatically show the PWB with a highlighted capacitor C2568. Click on the "Schematic" hyperlink to automatically show the position of the highlighted capacitor.

ComPair
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: · 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. · 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. · 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 SearchMan electronic manual of the defective chassis, schematics and PWBs are only a mouse click away.

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/STATUS button (do not allow the display to time out between entries while keying the sequence). Make sure the menu item CLEAR is highlighted. 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.
5.5.3
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 Blinking LED Procedure
Using 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 starts 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,
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.

Fault Finding and Repair Tips
Notes: · 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.
5.7.2
Tuner and IF No Picture in RF mode 1. Check whether picture is present in AV. If not, go to Video processing troubleshooting section. 2. If present, check that the Option settings are correct. 3. Check that all supply voltages are present. 4. Check if I2C lines are working correctly (3.3V). 5. Manually store a known channel and check if there is IF output at Tuner pin 11. 6. Feed in 105 dBuV at Tuner pin 11 and check whether there is RGB output from Video Processing IC. If yes, Tuner may be defected. Change 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 1. Check whether the Service jumper (#4022, 08 05 size) is present. If yes, remove it. 2. Check whether SEL_IF pin is according to what is specified.
5.7.3
Video Processing No power 1. Check +12 V and 3V3 at position 1910. 2. If no supply, check the connector 1910. 3. If it is correct, check the power supply board. Power supply is correct but no green light 1. Check the two connectors 1007 and 1008, if they are properly inserted. 2. If they are inserted correctly, check if the 3V3 is present. No picture display 1. Check the RGB signal. 2. If it is present, check pin 3 of IC7006 (NE555). 3. If it has output, the problem is in SCALER part. 4. Otherwise, check H-out on pin 2 of NE555. If the input signal of pin2 is present, but no output, the IC is failed. Note: · If the H-out (pin 67) doesn't have signal or the level is low, check the output of NE555 (pin 3) during start up. · If the H-out (pin 67) has a signal (or has a signal for a very short time), change IC7006 (NE555). No TV but PC is present 1. Check if HSYNC and VSYNC are present at PIN 3 of 7007 and 7005.
