. 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.

Definition of Pixel Defects
Philips' LCD Panel Pixel Defect Policy
Philips strives to deliver the highest quality products. We use some of
the industry's most advanced manufacturing processes and practise
stringent quality control. However, pixel or sub pixel defects on the TFT
LCD panels used in flat panel monitors are sometimes unavoidable. No
manufacturer can guarantee that all panels will be free from pixel
defects, but Philips guarantees that any monitor with an unacceptable
number of defects will be repaired or replaced under warranty. This
notice explains the different types of pixel defects and defines
acceptable defect levels for each type. In order to qualify for repair or
replacement under warranty, the number of pixel defects on a TFT LCD
panel must exceed these acceptable levels. For example, no more than
0.0004% of the sub pixels on a 15" XGA monitor may be defective.
Furthermore, Philips sets even higher quality standards for certain types
or combinations of pixel defects that are more noticeable than others.
Pixels and Sub pixels
A pixel, or picture element, is composed of three sub pixels in the
primary colors of red, green and blue. Many pixels together form an
image. When all sub pixels of a pixel are lit, the three colored subpixels
together appear as a single white pixel. When all are dark, the three
colored sub pixels together appear as a single black pixel. Other
combinations of lit and dark sub pixels appear as single pixels of other
colors.
Types of Pixel Defects
Pixel and sub pixel defects appear on the screen in different ways.
There are two categories of pixel defects and several types of sub pixel
defects within each category.
Bright Dot Defects appear as pixels or sub pixels that are always lit or
'on'. These are the types of bright dot defects:
-One lit red, green or blue sub pixel
Two adjacent lit sub pixels:
- Red + Blue = Purple
- Red + Green = Yellow
- Green + Blue = Cyan (Light Blue)
-Three adjacent lit sub pixels (one white pixel)
Black Dot Defects
Appear as pixels or sub pixels that are always dark or 'off'. These are
the types of black dot defects:
One dark sub pixel Two or three adjacent dark sub pixels
Proximity of Pixel Defects
Pixel Defect Tolerances
Because pixel and sub pixels defects of the same type that are near to
one another may be more noticeable, Philips also specifies tolerances
for the proximity of pixel defects.
In order to qualify for repair or replacement due to pixel defects during
the warranty period, a TFT LCD panel in a Philips flat panel monitor
must have pixel or sub pixel defects exceeding the tolerances listed in
the following tables.
Note: 1 or 2 adjacent sub pixel defects = 1 dot defect
