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 is also 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.
* * Hereafter throughout this manual, Philipsl Company will
be referred to as Philips.

sRGB is a standard for ensuring correct exchange of colors
between different devices (e.g. Digital cameras, monitors,
printers, scanners, etc.) Using a standard unified color space,
sRGB will help represent pictures taken by an sRGB compatible
device correctly on your sRGB enabled Philips monitors. In that
way, the colors are calibrated and you can rely on the correctness
of the colors shown on your screen. Important with the use of
sRGB is that the brightness and contrast of your monitor is fixed
to a predefined setting as well as the color gamut. Therefore it is
important to select the sRGB setting in the monitor's OSD.
To do so, at PC mode, open the OSD by pressing the MENU
button of your monitor. Use the down button to go to COLOR
SETTINGS and press MENU again. Then move the down button
to go to NORMAL COLOR and press MENU again. For more

TV and Audio Problems
COMMON
SYMPTOMS
Poor TV signal reception
Troubleshooting
WHAT YOU EXPERIENCEPOSSIBLE SOLUTIONS
Abnormal picture seen from the screen
The proximity of mountains or high buildings may be responsible for
ghost pictures, echoing or shadows. In this case, try manually
adjusting your pictures: see 'fine tuning' or adjust the direction of
the outside aerial. For Asia users in non-NTSC area: Does your
antenna enable you to receive broadcasts in this frequency range
UHF or VHF band)? In the event of difficult reception (snowy
pictures) switch the NR on the PICTURE menu to ON.

No picture when TV input was selected
No sound output when a program with
sound was playing
WHAT YOU EXPERIENCE
No signal indicator is displayed.
Picture not crisp and some color
Distortion
See video but no audio
WHAT YOU EXPERIENCE
No response from LCD TV when
remote is pressed
WHAT YOU SEE
Image is centered on screen, but
does not fill entire viewing area
OSD does not appear on the screen
Have you connected the aerial socket properly? Have you chosen
the right system? Poorly connected SCART Cables or aerial
sockets are often the cause of picture or sound problems
(sometimes the connectors can become half disconnected if the
LCD TV set is moved or turned). Check all connections.
Ensure that the audio cables are firmly connected to both the audio
input connectors on your LCD TV and audio output connectors on
your PC or Video player.
If on certain TV channels you receive a picture but no sound, this
means that you do not have the correct TV system. Modify the
SYSTEM setting.
POSSIBLE SOLUTIONS
Check Video Input Selection
Composite: Yellow colored RCAjack
S-Video: Typically a round 4 pin jack
Component: Typically 3 RCA jacks of Green, Red and Blue.
Check DVD connection
Composite gives good picture
S-Video gives better picture
Component gives best picture
Check if TV volume is turn off of muted
Connect the audio cable securely
Audio cable is connected incorrectly
Verify that the audio source is selected correctly in the OSD
POSSIBLE SOLUTIONS
Point the remote control directly at the remote sensor on the LCD TV
Replace both batteries with new onesl
POSSIBLE SOLUTIONS
Perform LCD TV reset on "All Settings"
Turn the LCD TV off and unplug the power cord and then plug back
and power on

Definition of Pixel Defects
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.
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:.
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 DEFECTSACCEPTABLE LEVEL

Black dot defects
Black dot defects appear as pixels or subpixels that are always
dark or "off"”TThese are the types of black dot defects:

2.2 Remove the lens protective cover of probe CA-A30.
2.3 Set Measuring/viewing selector to Measuring position for reset
analyzer. (Zero calibration) as Fig. 5
2.4 Turn on the colour analyzer (CA-110).
2.5 Press 0-CAL button to start reset analyzer. See Fig. 6
2.7 Move the Lens barrel forward or backward to get clear image as
shown in Fig. 7
2.8 Switch light probe to Measuring position. It should be able to
indicate colour value on the CA-110.

User mode. Set color setting at natural color on User mode. Move
cursor to "AUTO-SUB" item on factory mode, press "menu" key

i. Luminance>380 nits in the center of the screen at Original (
Natural ) color and PC Brightness control; Contrast control at
100%
ii. Luminance =180 +/- 15 nits in the center of the screen at sRGB
colour temp. (Brightness and Contrast control set at 50% ) .
Alignment hits:
R for x value , G for y value, B and Sub-brightness for Y value on the
Colour analyzer.
