Safety & Maintenance Instructions, Warnings, and Notes
2. Safety & Maintenance Instructions, Warnings, and 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. , should · Safety components, indicated by the symbol 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 re-solder 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 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 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 MW and 12 MW. 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.
2.3
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).
·
· · ·
2.4
Notes
· 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 chapter 5) with a color bar signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated otherwise) and picture carrier at 475.25 MHz (PAL) or 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. 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.
2.2
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.

CL 26532098/042 140792
Figure 2-1 · All ICs and many other semiconductors are susceptible . Careless handling to electrostatic discharges (ESD) 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.

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 pre-sets. · Managing of pre-set lists. · Emulation of the (European) 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 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. 5.4.3 How to Connect 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
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.

How to Clear the Error Buffer The error code buffer is cleared in the following cases: · By activation of the CLEAR command in the SAM menu: · When you exit SDM / SAM with the STANDBY command on the remote control (when leaving SDM / SAM, by disconnecting the set from AC power, the error buffer is not reset). · When you transmit the command DIAGNOSE-99-OK with ComPair. · If the content of the error buffer has not changed for 50 hours, it resets automatically.
5.5
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.
5.5.3
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).
5.5.1
How to Read the Error Buffer Use one of the following methods: · On screen via the SAM (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

Service Modes, Error Codes and Fault Finding 5.6 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 SDM is entered, the LED will blink the contents of the error-buffer. Error-codes ³ 10 are shown as follows: a long blink of 750 ms (which is an indication of the decimal digit), a pause of 1.5 s, n short blinks (n = 1 - 9), 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 SDM: 1 long blink of 750 ms followed by a pause of 1.5 s, 2 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. ·

the same time, measure the `+8V'. If this voltage is missing, check transistor TS7480. 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: resistor 3460 is defective. Set turns on, but with a half screen at the bottom. Sound is okay Blinking LED (set in SDM mode) indicates error 3. Check `Vlotaux+13V' and `+50V'. If they are okay, problem is expected in the vertical amplifier IC7471. Measure with a scope the waveform on pin 17 of the UOC. Measure also at pin 1 of IC7471. If here the signal is missing, a defective resistor R3244 causes the problem.
5.7
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 (SAM), the blinking LED procedure or via ComPair. The DST diagnose functionality will force the set into the Servicestandby, which is similar to the usual standby mode, however the microprocessor has to remain in normal operation completely. To get a quick diagnosis the chassis has three service modes implemented: · The Customer Service Mode (CSM). · The Service Default Mode (SDM). Start-up of the set in a predefined way. · The Service Alignment Mode (SAM). Adjustment of the set via a menu and with the help of test patterns. See for a detailed description Chapter 9 paragraphs Deflection and Power Supply.
