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
1
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
2
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
4
voltage via an isolating transformer.
. Be careful when taking measurements in the high-voltage
5
section and on the picture tube panel.
0V
Notes
1.
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)
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(s)
3.
and in the parts lists are completely interchangeable per position with the semiconductors in the unit, irrespective of the type indication on these semiconductors.
V
. It is recommended that saferty goggles be worn when
6
replacing the picture tube.
. When making adjustments,use plastic rather than metal tools.
7
This will prevent any short-circuit or the danger of a
circuit becoming unstable.
. Never replace modules or other components while the
8
unit is switched on.
. Together with the defleciton unit, the picture tube is used
9
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

DDC Instructions
1. General
DDC Data Re-programming
In case the main EEPROM with 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 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).
