. Safety regulations require that the unit should be returned

in its original condition and that components identical to the original components are used. The safety components are indicated by the symbol .

. In order to prevent damage to ICs and transistors, all

high-voltage flash-overs must be avoided. In order to prevent damage to the picture tube, the method shown in Fig. 1 should be used to discharge the picture tube. Use a high-voltage probe and a multimeter (position DC-V). Discharge until the meter reading is (after approximately 30 seconds).

All ICs and many other semiconductors are sensitive to electrostatic discharges (ESD). Careless handling during repair can drastically shorten their life. Make sure that during repair you are connected by a pulse band with resistance to the same potential as the ground of the unit. Keep components and tools also at this same potential.

. When repairing a unit, always connect it to the AC Power

voltage via an isolating transformer.

. Be careful when taking measurements in the high-voltage

section and on the picture tube panel.

. It is recommended that saferty goggles be worn when

replacing the picture tube.

. When making adjustments,use plastic rather than metal tools.

This will prevent any short-circuit or the danger of a

circuit becoming unstable.

. Never replace modules or other components while the

unit is switched on.

. Together with the defleciton unit, the picture tube is used

as an integrated unit. Adjustment of this unit during repair is not recommended.

After repair, the wiring should be fastened in place with the cable clamps.

All units that are returned for service or repair must pass the original manufactures safety tests.

Notes

The direct voltages and waveforms are average voltages. They have been measured using the Service test software and under the following conditions :

- Mode : 640 * 480 (31.5kHz / 60Hz)

- Signal pattern : grey scale

- Adjust brightness and contrast control for the mechanical mid-position (click position)

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(s) and in the parts lists are completely interchangeable per position with the semiconductors in the unit, irrespective of the type indication on these semiconductors.

This is done by moving the two tabs (2-pole) in such a manner that they advance in an opposite direction but at the same time to obtain the same angle between the two tabs, which should be approximately 180 degree.

- Check by full green pattern and full blue pattern again to observe their respective color purity.

Introduction Slight deviation in the static convergence can be corrected by using two permanent pairs of magnets which are fitted around the neck of the CRT. These are the 4-pole magnet and the 6-pole magnet. The 4-pole magnet move the outermost electron beams (R and B) parallel in the opposite direction from the other. The 6-pole magnet moves the outermost electron beam (R, B and G) parallel in the opposite direction from the other. The magnetic field of the above magnets do not affect the center of the CRT neck.

Setting

- Before the static convergence setting can be made,

the monitor must be switched on for 30 minutes.

- The focus setting must be made correctly.

- Signal: 640 * 480, 31.5 kHz/60 Hz mode.

- Set the tabs of the 4-pole magnet in the neutral

position. This is when the tabs are opposite one another. In this position the magnets do not affect the deflection of the R and B electron beams.

- Set the tabs of the 6-pole magnet in the neutral

position. This is when the tabs are opposite one another. In this position the magnets do not affect the deflection of the R, B, and G electron beams.

- First set the 4-pole magnet optimally.

- Then set the 6-pole magnet optimally.

- If the convergence is not now optimal, then adjust to

the optimal setting with the 4-pole magnet and then with the 6- Pole magnet again.

- Set the tabs of the 6-pole magnet in the neutral

position. This is when the tabs are opposite one another. In this position the magnets do not affect the deflection of the R, B, and G electron beams.

- First set the 4-pole magnet optimally.

- Then set the 6-pole magnet optimally.

- If the convergence is not now optimal, then adjust to

the optimal setting with the 4-pole magnet and then with the 6- pole magnet again.
