Proper service and repair is important to the safe, reliable operation of all PHILIPS Company** Equipment.

The service procedures recommended by PHILIPS and described in this service manual are effective methods of performing service operations. Some of these service

operations require the use of tools specially designed for the purpose. The special tools should be used when and as recommended.

It is important to note that this manual contains various CAUTIONS and NOTICES which should be carefully

Read in order to minimize the risk of personal injury to service personnel. The possibility exists that improper Service methods may damage the equipment. It also is

important to understand that these CAUTIONS and NOTICES ARE NOT EXHAUSTIVE. PHILIPS could not possibly know, evaluate and advise the service trade of

all conceivable ways in which service might be done or of the possible hazardous consequences of each way.

Consequently, PHILIPS has not undertaken any such broad evaluation. Accordingly, a servicer who uses a service procedure or tool which is not recommended by PHILIPS must first satisfy himself thoroughly that

neither his safety nor the safe operation of the equipment will be jeopardized by the service method selected.

Warning and Notes

Warnings

. 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).

3 ESD

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.

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.

. 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

10.

the cable clamps.

All units that are returned for service or repair must pass

11.

the original manufactures safety tests.

9. Loading DDC code

The DDC HEX data should be written into the EEPROM (7802) by EDID301.EXE Program(3138 106 10103) and software DDC Alignment kits (4822 310 11184).

10. Purity adjustment

- Make sure the monitor is not exposed to any external magnetic field.

- Produce a full red pattern on the screen, adjust the purity magnet rings on the PCM assy (on CRT) to obtain a complete field of the color red. 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.

11. Static convergence

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.

DDC Instructions

1. General

DDC Data Re-programming

In case the main EEPROM with Software DDC which store all factory settings were replaced because a defect,repaired monitor the serial numbers have to be re-programmed.

It is advised to re-soldered the main EEPROM with Software DDC from the old board onto the new board if circuit board have been replaced, in this case the DDC data does not need to be re-programmed.

Additional information

Additional information about DDC (Display Data Channel) may be obtained from Video Electronics Standards Association (VESA). Extended Display Identification Data(EDID) information may be also obtained from VESA.

4. Configuration and procedure

There is no Hardware DDC (DDC IC) anymore. Main EEPROM stores all factory settings and DDC data (EDID code) which is so called Software DDC. The following section describes the connection and procedure for Software DDC application. The main EEPROM can be reprobrammed by enabling "factory memory data write" function on the DDC program (EDID301.EXE).

*** INITIALIZE ALIGNMENT BOX ***

In order to avoid that monitor entering power saving mode due to sync will cut off by alignment box, it is necessary to initialize alignment box before re-programming DDC Data. Following steps show you the procedures and connection.

Step 1

: Supply 8~12V DC power source to the Alignment box by

plugging a DC power cord or using batteries.

Step 2

: Connecting printer cable and video cable of monitor as

shown in Fig.3.
