0. General
This section explains the different types of pixel defects and
defines acceptable defect levels of 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.
1. Definition of Pixels and Subpixels
A pixel, or picture element , is composed of three subpixels in the
primary colors of red, green and blue. Many pixels together from
an image. When all subpixels of a pixel are lit, the three colored
subpixels together appear as a single white pixel. When all are
dark, the three colored subpixels together appear as a single black
pixel. Other combinations of lit and dark subpixels appear as
single pixels of other colors.

2. Types of Pixel Defects
Pixel and subpixel defects appear on the screen in different ways.
3. Pixel Defect Tolerances
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 subpixel defects exceeding the
tolerances listed in the following tables.
Bright dot defects
Bright dot defects appear as pixels or subpixels that are always lit
or “On”. These are the types of bright dot defects:.
One lit red, green or blue subpixel
Two adjacent lit subpixels:
- Red + Blue = Purple
- Red + Green = Yellow
- Green + Blue = Cyan (Light Blue)
Three adjacent lit subpixels
(One white pixel)
Black dot defects
Black dot defects appear as pixels or subpixels that are always
dark or “off”. These are the types of black dot defects:
One dark subpixel
Two or three adjacent dark subpixels

0. General
When carry-out the electrical settings in many cases a video
signal must be applied to the monitor. A computer with :
- ATI VGA 1024 V6-1.04/PH BETA4 interface card
- PGA 1024 (4822 212 30916), Mach 8.
- PGA 1280 (4822 212 30917), Mach 32.
- ATI GPT-1600 (4822 397 10065), Mach 64 (up to 107kHz)
are used as the video signal source. The signal patterns are
selected from the "service test software" package, see user
guide 4822 727
19896 (ATI1024), or 4822 727 20273 (PGA 1280), or
4822 727 21046 (GPT-1600).
0.1 With normal VGA card:
If not using the ATI card during repair or alignment, The service
engineer also can use this service test software adapting with
normal standard VGA adaptor and using standard VGA mode
640 x 480, 31.5 kHz/60 Hz (only) as signal source.
0.2 AC/DC Measurement:
The measurements for AC waveform and DC figure is based on
640 x 480 31.5 kHz/60 Hz resolution mode with test pattern "gray
scale".
1.General points
1.1 During the test and measuring, supply a distortion free AC mains
voltage to the apparatus via an isolated transformer with low
internal resistance.
1.2 All measurements mentioned hereafter are carried out at a
normal mains voltage (90 - 132 VAC for USA version, 195 -264
VAC for EUROPEAN version, or 90 - 264 VAC for the model with
full range power supply, unless otherwise stated.)
1.3 All voltages are to be measurement or applied with respect to
ground, unless otherwise stated. Note: don't use heat-sink as
ground.

4. Configuration and procedure
There are three chips contained serial number on the circuit board,
Analog DDC IC (7301), Digital DDC IC (7302) and main EEPROM
(7204) which storage all factory settings. Following descriptions are the
connection and procedure for Analog DDC IC and Digital DDC IC, the
main EEPROM can be re-programmed along with Analog IC by enable
“factory memory data write” function on the DDC program
(EDID30.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 running programming software (EDID30.EXE).
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 Fig. A
