5.1 Test Points

The chassis is equipped with test points printed on the circuit board assemblies. These test points refer to the functional blocks:

Table 5-1 Test Point Overview

The numbering is in a logical sequence for diagnostics. Always start diagnosing within a functional block in the sequence of the relevant test points for that block. Perform measurements under the following conditions:• Service Default Alignment Mode.• Video: colour bar signal.• Audio: 3 kHz left, 1 kHz right.

5.2 Service Modes

Service Default Alignment Mode (SDAM) offers several features for the service technician, while the Customer Service Mode (CSM) is used for communication between dealer and customer.There is also the option of using ComPair, a hardware interface between a computer (see requirements) and the TV chassis. It offers the ability of structured trouble shooting, error code reading and software version readout for all chassis. Requirements: To run ComPair on a computer (laptop or desktop) requires, as a minimum, a 486 processor, Windows 3.1 and a CD-ROM drive. A Pentium Processor and Windows 95/98 are also acceptable (see also paragraph 5.4).

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.

• 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.

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. In case of the L01 chassis, the ComPair interface box and the TV communicate via a bi-directional service cable via the service connector (located on the Main panel, see also figure 8-1 suffix D). 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 extend. When this is not the case, ComPair will guide you through the faultfinding tree by asking you questions (e.g. Does the screen gives 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 presets.• Managing of preset lists.• 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 Monocarrier.

• 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.

Service Modes, Error Codes and Fault Finding EN 21L01.1A AC 5.

5.4.3 How To Connect ComPair

1. First install the ComPair Browser software (see the Quick Reference Card for installation instructions).

2. Connect the RS232 interface cable between a free serial (COM) port of your PC and the PC connector (marked with “PC”) of the ComPair interface.

3. Connect the AC power adapter to the supply connector (marked with “POWER 9V DC”) on the ComPair interface.

4. Switch the ComPair interface OFF.5. Switch the television set OFF (remove the AC power).6. Connect the ComPair interface cable between the

connector on the rear side of the ComPair interface (marked with “I2C”) and the ComPair connector on the mono carrier (see figure 8-1 suffix D).

7. Plug the AC power adapter in the AC power outlet and switch on the interface. The green and red LEDs light up together. The red LED extinguishes after approx. 1 second while the green LED remains lit.

8. Start the ComPair program and read the “introduction” chapter.

5.4.5 Error Buffer

The error code buffer contains all detected errors 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 written at the left side and all other errors shift one position to the right.

5.4.6 How To Read The Error Buffer

You can read the error buffer in 3 ways:• On screen via the SDAM (only 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 first detected and

error code 9 is the last detected (newest) error• Via the blinking LED procedure (when you have no

picture). See next paragraph.• Via ComPair.

5.4.7 How To Clear The Error Buffer

The error code buffer is cleared in the following cases:• By activation of the CLEAR command in the SDAM menu:• If the content of the error buffer has not changed for 50

hours, it resets automatically. Note:When leaving SDAM by disconnecting the set from AC power, the error buffer is not reset.

5.4.8 Error Codes

In case of non-intermittent faults, clear the error buffer before you begin the repair. These to ensure 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 code and not the actual cause (e.g., a fault in the protection detection circuitry can also lead to a protection).

5.5 The Blinking LED Procedure

Via 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 SDAM is entered, the LED will blink the contents of the error-buffer. • n short blinks (n = 1 - 14),• when all the error-codes are displayed, the sequence

finishes with a LED blink of 3 s,• the sequence starts again. Example of error buffer: 12 9 6 0 0 After entering SDAM: • 12 short blinks followed by a pause of 3 s,• 9 short blinks followed by a pause of 3 s,• 6 short blinks followed by a pause of 3 s,• 1 long blink of 3 s to finish the sequence,• the sequence starts again.

5.6 Protections

If a fault situation is detected an error code will be generated and if necessary the set will be put in the 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 the protection mode. The error codes of the error buffer can be read via the service menu (SDAM), the blinking LED procedure or via ComPair. To get a quick diagnosis the chassis has two service modes implemented:• The Customer Service Mode (CSM).• The Service Default Alignment Mode (SDAM). Start-up of

the set in a predefined way and adjustment of the set via a menu and with the help of test patterns.

5.7 Repair Tips

Below some failure symptoms are given, followed by a repair tip.• Set is dead and makes hiccuping sound “MainSupply” is

available. Hiccupping stops when de-soldering L5561, meaning that problem is in the “MainSupply” line. No output voltages at LOT, no horizontal deflection. Reason: line transistor 7460 is defective.

• Set is dead, and makes no soundCheck power supply IC 7520. Result: voltage at pins 1, 3, 4, 5 and 6 are about 180 V and pin 8 is 0 V. The reason why the voltage on these pins is so high is because the output driver (pin 6) has an open load. That is why MOSFET 7521 is not able to switch. Reason: feedback resistor 3523 is defective. Caution: be careful measuring on the gate of 7521; circuitry is very high ohmic and can easily be damaged!

• Set is in hiccup mode and shuts down after 8 s.Blinking LED (set in SDAM mode) indicates error 5. As it is unlikely that µP “POR” and “+8V protection” happen at the same time, measure the “+8V”. If this voltage is missing, check transistor 7480.

• Set is non-stop in hiccup modeSet is in over current mode; check the secondary sensing (opto coupler 7515) and the “MainSupply” voltage. Signal “Stdby_con” must be logic low under normal operation conditions and goes to high (3.3 V) under standby and fault conditions.

• Set turns on, but without picture and soundThe screen shows snow, but OSD and other menus are okay. Blinking LED procedure indicates error 11, so problem is expected in the tuner (pos. 1000). Check presence of supply voltages. As “Vlotaux+5V” at pin 5 and 7 are okay, “VT_supply” at pin 9 is missing. Conclusion: resistor 3460 is defective.

• Set turns on, but with a half screen at the bottom. Sound is okayBlinking LED (set in SDAM mode) indicates error 3. Check “Vlotaux+11V” and “+50V”. If they are okay,

problem is expected in the vertical amplifier IC 7471. Measure with a scope the waveform on pin 17 of the UOC. Measure also at pin 1 of IC 7471. If here the signal is missing, a defective resistor R3244 causes the problem
