Index of this chapter:
2.1 Safety Instructions
2.2 Maintenance Instructions
2.3 Warnings
2.4 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.
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 is flowing. 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 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.
2.2 Maintenance Instructions
We 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:
1. Perform the “general repair instruction” noted above.
2. Clean the power supply and deflection circuitry on the chassis.
3. Clean the picture tube panel and the neck of the picture tube.
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 V until the meter reading is 0 V (after approx. 30 s).
V
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 the danger of a circuit becoming unstable.
2.4 Notes
2.4.1 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).
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 semiconductors in the unit, irrespective of the type indication on these semiconductors.

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, 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. 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. 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.
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 at least a solder-tip temperature of 400°C. – To stabilise the adjusted temperature at the solder-tip. – To exchange solder-tips for different applications.
Adjust your solder tool so that a temperature around 360°C
- 380°C is reached and stabilised 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 rise 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 not to avoid, clean carefully 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 short 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 90°C) 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
EN 6 L05.1U AA3.
Directions for Use
be available till the end of the service period. For the repair of such sets nothing changes.
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 "Workshop information".

For additional questions please contact your local repair help desk.
2.4.5 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.

How to exit
Switch the set to STANDBY by pressing the POWER button on the remote control transmitter or the television set. If you turn the television set “off” by removing the AC power (i.e., unplugging the television) without using the POWER button, the television set will remain in SAM when AC power 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 TV’s operation settings. The call center can instruct the customer (by telephone) to enter CSM in order to identify the status of the set. This helps the call center 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:
Press the MENU, STATUS/EXIT, or POWER button on the remote control transmitter.
Press the POWER button on the television set.
5.2.4 Digital Customer Service Mode (DCSM)
Purpose
The Digital Customer Service Mode shows error codes and information on the TV’s digital operation settings. The call center can instruct the customer (by telephone) to enter DCSM in order to identify the digital status of the set. This helps the call center to diagnose problems and failures with the ATSC part before making a service call. The DCSM is a read-only mode; therefore, modifications are not possible in this mode, with exception of the digital error buffer. This error buffer can be cleared in DCSM.
How to enter
To enter DCSM, the set has to be in digital mode. When the set is in digital mode, 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 Digital Customer Service Mode, the following screen will appear:

5.4 ComPair
5.4.1 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.
EN 12 L05.1U AA5.
Service Modes, Error Codes, and Fault Finding
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.
5.4.2 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 RS232) 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:
Automatic (by communication 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 extend. 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.
Beside fault finding, ComPair provides some additional features like:
Up- or downloading of pre-sets.
Managing of pre-set lists.
Emulation of the (European) Dealer Service Tool (DST).
If both ComPair and Force/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.

5.5 Error Codes
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). See “The Blinking LED Procedure”.
•Via ComPair.

EN 13L05.1U AA 5.
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/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”

34 TA1317AFG I2C error while communicating with the ATSC deflection controller - ATSC module
35 SAA5565 I2C error while communicating with the ATSC uProcessor - ATSC module
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 AC power 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
5.6 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:
When all the error-codes are displayed, the sequence finishes with a LED blink of 1.5 seconds,
The sequence starts again.
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 at 12 short blinks.
5.7 Protections
If a fault situation is detected, an error code will be generated; and, if necessary, the television set will go into protection mode. Blinking of the red LED at a frequency of 3 Hz indicates the protection mode. In some error cases, the microprocessor does not put the set in protection mode. The error codes of the error buffer and the blinking LED procedure can be read via the Service Default Menu (SDM), or via ComPair.
To get a quick diagnosis the chassis has three service modes implemented:
The Customer Service Mode (CSM).
The Service Default Mode (SDM).
The Service Alignment Mode (SAM).
The Digital Customer Service Mode (DCSM).
For a detailed mode description, see the relevant sections.
5.8 Fault Finding and Repair Tips

Service Modes, Error Codes, and Fault Finding
EN 17L05.1U AA 5.
5.8.6 Controller
Below are some guidelines for troubleshooting of the Micro Controller function. Normally Micro Controller should be checked when there is a problem of startup.
1. Check that both +3.3 V_dc and +1.8 V_dc are present.
2. Check that crystal oscillator is working.
3. Check that Power Good signal is at “high” logic, normal operation.
4. Check that HERCULES is not in standby mode. Pin 15 of HERCULES should be 0 V_dc.
5. Make sure H-drive pulse is there. This can be checked at resistor R3239. If H-drive does not exist, remove resistor R3239 to check if there is loading.
Note: When the set shuts down after a few second after power “on”, the main cause is that Vg2 not aligned properly, try adjusting Vg2 during the few seconds of power “on”.
5.8.7 Video Processing
No Picture
When “no picture in RF”, first check if the microprocessor is functioning ok in section “Controller”. If that is ok, follow the next steps. When “no picture in AV”, first check if the video source selection is functioning ok in section “Source Selection”. If that is ok, follow the next steps.
1. Check that normal operating conditions are met.
2. Check that there is video signal at pin 81. If no video, demodulator part of the HERCULES is faulty, replace with new HERCULES.
3. If video signal is available at pin 81, check pin 56, 57, and 58 for the RGB signal.
4. If signal is not available, try checking the BRIGHTNESS and/or CONTRAST control, and make sure it is not at zero.
5. If still with the correct settings and no video is available, proceed to the CRT/RGB amplifier diagram.
For sets with TDA9178, follow steps below:
1. Put Option Byte 2 bit 4 to “0”; if video signal is not available, then check fault finding section “Controller”, Section “Source Selection”, and steps above.
2. If video is available but not correct, put Option Byte 2 bit 4 to “1”, then check if LTI panel is present. If not, put LTI panel in the main chassis (connector 1221).
3. If LTI panel is in main chassis, check cable between LTI panel and main chassis (position is 1206). If it is connected, then the LTI panel is faulty, replace it.
For sets with Scavem, and Scavem does not work, follow steps below:
1. Check Scavem coil connector (position is 1361) if connected; if not, connect it.
2. If connected, check NVM “bit storage” byte 1 bit 7; if it is not “1”, set it to “1”.
3. If it is “1”, then check the data of the NVM addresses as in the next table. If the data is not correct, then set these addresses to diagram values.
4. If it still not works, track Scavem output from pin64 of HERCULES to CRT panel.

Figure 5-14 Fault finding tree “No sound”
No RF audio for QSS/Inter-Carrier stereo sets.
1. Check pin 99 and 100 for SIF signal (for QSS) or pin 104 and 105 for video with SIF (for Inter-Carrier)
2. If signal is not present, check for the QSS/FMI bit settings. Check also the NVM data.
3. If signals are present and still no audio, check the audio supply voltage +8V are present.
4. If still no audio signal at Hercules output, Hercules is faulty.
No AV audio.
1. Check troubleshooting methods in section “Source Selection”.
2. Check the output of the Hercules to see if there is signal available. If no, check the normal operating condition and also the NVM data.
3. If still no audio signal at Hercules output, Hercules is faulty.
Note: If there is audio signal at Hercules output and no audio
at loudspeaker, proceed to Audio Amplifier troubleshooting methods.
5.8.9 Audio Amplifier
No RF as well as AV audio at the loudspeaker:
1. Check that the normal operation condition of the amplifier is met.
2. If normal operation conditions are met, check the continuity from Hercules output to input of the amplifier.
3. If continuity is there and still no audio, check speaker wire connections. If still no audio, amplifier IC might be faulty.
