Safety and Maintenance Instructions, Warnings, and NotesEN 4 TC2.1A2.
2. Safety and Maintenance Instructions, Warnings, and Notes
2.1 Safety Instructions
Safety regulations require that during a repair:• Due to the chassis concept, a very large part of the circuitry
(incl. deflection) is 'hot'. Therefore, connect the set to the mains via an isolation transformer.
• Replace safety components, indicated by the symbol , 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, you must return the set 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 cord for external
damage.• Check the strain relief of the mains 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 plug and the secondary side (only for sets that have an isolated power supply). Do this as follows:1. Unplug the mains cord and connect a wire between the
two pins of the mains plug.2. Turn on the main power switch (keep the mains cord
unplugged!).3. Measure the resistance value between the pins of the
mains plug and the metal shielding of the tuner or the aerial connection of the set. The reading should be between 4.5 MΩ and 12 MΩ.
4. Switch the TV 'off' and remove the wire between the two pins of the mains plug.
• Check the cabinet for defects, to prevent the possibility of the customer touching any internal parts.
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 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. 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 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. We do not recommend adjusting this unit during repair.
• Be careful during measurements in the high voltage section and on the picture tube.
• Never replace modules or other components while the unit is '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
• Measure the voltages and waveforms with regard to the chassis (= tuner) ground (), or hot ground (), 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 (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 interchangeable per position with the semiconductors in the unit, irrespective of the type indication on these semiconductors.

screen will become a horizontal line. Then adjust the "SCREEN" VR on the flyback transformer to set the intensity of the line to a minimum visible level (the line can just be seen).
4. Press the "MUTE" key again and the screen will show a full raster.
5. Select BRTC to adjust the sub-brightness, until that the 2nd dark bar of 8 level grey scales just can be seen.
8.1.7 Adjustment of White balance
1. Apply a black and white pattern at STANDARD status.2. Use a colour analyser to measure the black side of the
screen. By changing the value of BB and GB, set the reading of the colour analyser to x=284, y=299.
3. Then measure the white side of the screen. By changing the value of BD and GD, set the reading of the colour analyser to x=284, y=299.
4. Repeat step 2 and 3 until you can get the correct reading for both black and white sides.
8.1.8 Adjustment of Pincushion and Picture Width (for pure flat model only)
1. Apply a crosshatch pattern.2. Adjust VR302 until the vertical line becomes straight.3. Adjust VR303 for horizontal size.
8.1.9 Adjustment of Picture Geometry (PAL)
1. Apply a crosshatch pattern (PAL signal) to the RF input, in STANDARD status.
2. Select HPOS to adjust the Horizontal centre.3. Select VP50 to adjust the Vertical centre.4. Select HIT to adjust the Vertical amplitude.5. Select VLIN to adjust the vertical linearity.6. Select VSC to adjust the vertical S-correction.
8.1.10 Adjustment of Picture Geometry (NTSC)
1. Apply a crosshatch pattern (NTSC signal) to the RF input, in STANDARD status.
2. Select HPS to adjust the Horizontal centre.3. Select VP60 to adjust the Vertical centre.
