Safety and Maintenance Instructions, Warnings, and NotesEN 4 L03.1L AA2.

2. Safety and Maintenance Instructions, Warnings, and Notes

Index of this chapter:1. Safety Instructions for Repairs2. Maintenance Instructions3. Warnings4. Notes

2.1 Safety Instructions for Repairs

Safety regulations require that during a repair:• Due to the 'hot' parts of this chassis, the set must be

connected to the AC power via an isolation transformer.• Safety components, indicated by the symbol �, should be

replaced by components identical to the original ones.• When replacing the CRT, safety goggles must be worn. Safety regulations require that after a repair, the set must be returned in its original condition. Pay particular attention to the following points:• General repair instruction: as a strict precaution, we advise

you to resolder the solder connections through which the horizontal deflection current is flowing, in particular:– all pins of the line output transformer (LOT)– fly-back capacitor(s)– S-correction capacitor(s)– line output transistor– pins of the connector with wires to the deflection coil– other components through which the deflection current

flows.Note: This resoldering 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 AC power cord for external

damage.• Check the strain relief of the 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 AC plug and the secondary side (only for sets that have an isolated power supply). Do this as follows:1. Unplug the AC power cord and connect a wire between

the two pins of the AC plug.2. Turn on the main power switch (keep the AC power

cord unplugged!).3. Measure the resistance value between the pins of the

AC plug and the metal shielding of the tuner or the aerial connection of the set. The reading should be between 4.5 MOhm and 12 MOhm.

4. Switch the TV 'off' and remove the wire between the two pins of the AC plug.

• Check the cabinet for defects, to prevent the possibility of the customer touching any internal parts.

2.2 Maintenance Instructions

It is recommended to have a maintenance inspection carried out by qualified service personnel. The interval depends on the usage conditions:• When the set is used under normal circumstances, for

example in a living room, the recommended interval is three to five years.

• When the set is used 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 Fig. 2-1, to discharge the picture tube. Use a high voltage probe and a multi-meter (position Vdc). Discharge until the meter reading is 0 V (after approx. 30 s).

Figure 2-1 Discharge picture tube

• All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD �). Careless handling during repair can reduce life drastically. When repairing, make sure that 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 potential.

• Available ESD protection equipment:– Complete kit ESD3 (small tablemat, wristband,

connection box, extension cable, and ground cable) 4822 310 10671.

– Wristband tester 4822 344 13999.• Together with the deflection unit and any multi-pole unit,

flat square picture tubes form an integrated unit. The deflection and the multi-pole units are set optimally at the factory. Adjustment of this unit during repair is therefore not recommended.

• Be careful during measurements in the high voltage section and on the picture tube.

• 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 (), or hot ground (), depending on the area of circuitry being tested.

• The voltages and waveforms shown in the diagrams are indicative. Measure them in the Service Default Mode (see “Service Modes, Error Codes, and Faultfinding” section) with a color bar signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated otherwise) and picture carrier at 61.25 MHz (NTSC, channel 3).

• Where necessary, measure the waveforms and voltages with (�) and without (�) aerial signal. Measure the voltages in the power supply section both in normal operation ( ) and in standby (�). These values are indicated by means of the appropriate symbols.

CL96532156_040.eps140501

Safety and Maintenance Instructions, Warnings, and Notes EN 5L03.1L AA 2.

• The picture tube panel has printed spark gaps. Each spark gap is connected between an electrode of the picture tube and the Aquadag coating.

• The semiconductors indicated in the circuit diagram and in the parts lists are completely interchangeable per position with the semiconductors in the unit, irrespective of the type indication on these semiconductors.

2.4.2 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 expressed 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.

2.4.3 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.

• Before powering up the TV set with the back cover off (or on a test fixture), attach a clip lead to the CRT DAG ground and to a screwdriver blade that has a well insulated handle. After the TV is powered on and high voltage has developed, probe the anode lead with the blade, starting at the case of the High Voltage Transformer (flyback - IFT). Move the blade to within two inches of the connector of the CRT. If there is an arc, you found it the easy way, without getting a shock! If there is an arc to the screwdriver blade, replace the part which is causing the problem; the High Voltage Transformer or the lead (if it is removable).

Service Modes, Error Codes, and Fault FindingEN 16 L03.1L AA5.

5. Service Modes, Error Codes, and Fault Finding

Index:1. Test points.2. Service Modes.3. Problems and Solving Tips.4. ComPair5. The Blinking LED Procedure.6. Protections.7. Repair Tips.

5.1 Test Points

This chassis is equipped with test points in the service printing. In the schematics test points are identified with a rectangle box around Fxxx or Ixxx.

Table 5-1 Test Point Overview

Perform measurements under the following conditions:• Service Default Alignment Mode.• Video: color 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. 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 however preferred (see also paragraph 5.4).

Table 5-2 SW Cluster

5.2.1 Service Default Alignment Mode (SDAM)

Purpose• To change option settings.• To create a predefined setting to get the same

measurement results as given in this manual.• To display / clear the error code buffer. • To override SW protections.• To perform alignments.• To start the blinking LED procedure.

Specifications• Tuning frequency: 61.25 MHz (channel 3) for NTSC-sets

(LATAM).• Color system: PAL-M for LATAM BI/TRI/FOUR-NORMA.• All picture settings at 50 % (brightness, color contrast,

hue).• Bass, treble and balance at 50 %; volume at 25 %. • All service-unfriendly modes (if present) are disabled, like:

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 (Dealer Service Tool), 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 L03 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:• Automatically (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 give a picture? Click on the correct answer: YES / NO) and showing you examples (e.g. Measure test-point F001 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.• 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.

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.

• ComPair interface cable: 3122 785 90004.

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 out 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.

Service Modes, Error Codes, and Fault Finding EN 19L03.1L AA 5.

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. It is wise to write down the errors of the error buffer before you clear it.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).

Table 5-3 Error Code Table

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 activated, 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 activating 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 one service mode implemented:• 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 hiccupping sound. “MainSupply” is available. Hiccupping stops when de-soldering L5563, meaning that problem is in the “MainSupply” line. No output voltages at LOT, no horizontal deflection. Reason: line transistor 7421 is defective.

• Set is dead, and makes no sound. Check power supply IC 7520. Result: voltage at pins 2, 6, 7, 9 and 11 are about 180 V and pin 14 is 0 V. The reason why the voltage on these pins is so high is because the output driver (pin 11) 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 the “POR” and “+8V protection” happen at the same time, measure the “+8V”. If this voltage is missing, check transistor 7491 & 7496.

• Set is non-stop in hiccup mode. Set 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 sound. The 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: resistors 3449 & 3450 are defective
