Proper service and repair isimportant to the safe, reliable
operation of all HPConsumer Electronics Company**
Equipment. The service procedures recommended by HP and
described in this service manual are effective methods of
performing service operations. Some ofthese 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. HP 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, HP has not
undertaken any such broad evaluation. Accordingly, a
servicer who uses a service procedure or tool which is not
recommended by HP 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, HP Consumer
Electronics Company will bereferred to as HP.
Critical components having special safety characteristics are
identified with a bythe Ref. No. inthe parts list and
enclosed within a broken line*
(where several critical components are grouped in one area)
along with the safety symbol on the schematics or
exploded views.
Use of substitute replacement parts which do not have the
same specified safety characteristics may create shock, fire,
or other hazards.
Under no circumstances should the original design be
modified or altered without written permission from Philips.
Philips assumes no liability, express or implied, arising out of
any unauthorized modification of design.
Servicer assumes all liability.

WARNING
Take care during handling the LCD module with backlight
unit
- Must mount the moduleusing mounting holes arranged infour
corners.
- Do not press onthe panel, edge of theframe strongly or electric
shock as this will result in damage to the screen.
- Do not scratch orpress on the panel withany sharp objects, such
as pencil or pen asthis may result in damage to the panel.
- Protect the module fromthe ESD as it maydamage the electronic
circuit (C-MOS).
- Make certain that treatment person s body are grounded through
wrist band.
- Do not leave themodule in high temperature andin areas of high
humidity for a long time.
- Avoid contact with water as it may ashort circuit within the module.
- If the surface ofpanel become dirty, please wipe it off with a soft
material. (Cleaning with a dirty or rough cloth may damage the
panel.)
FOR PRODUCTS CONTAINING LASER :
DANGER- Invisible laser radiation when open.
AVOID DIRECT EXPOSURE TO BEAM.
CAUTION- Use of controls or adjustments or
performance of procedures other than
those specified herein may result in
hazardous radiation exposure.
CAUTION- The use of optical instruments with this
product will increase eye hazard.
TO ENSURE THE CONTINUED RELIABILITY OF THIS
PRODUCT, USE ONLY ORIGINAL MANUFACTURER'S
REPLACEMENT PARTS, WHICH ARE LISTED WITH THEIR PART
NUMBERS IN THE PARTS LIST SECTION OF THIS

2.4 Check brightness uniformity
Set contrast at 50% and turn the brightness to get average
above 200 nits.
Apply the pattern 1. It should comply with the following formula:
Minimum luminance of nine points (brightness)
>= 0.75 (Min.)
Maximum luminance of nine points (brightness)
2.5 Check Cross talk

2.6 Check picture flicker (B)
Apply a 1280*1024 /60Hz signal with pixel on/off pattern.
Set color temperature at original panel color.
Set brightness control at 100%, and contrast control at 50%.
Check picture flicker should not be visible.

Step 6: Save DDC data
Sometimes, you may need to save DDC data as a text file for using
in other IC chip. To save DDC data, follow the steps below:
1. Click (Save) icon (or click "file"-> "save as") from the tool bar
And give a file name as shown in Fig. 24.
The file type is EDID45 file (*.ddc) which can be open in WordPad.
By using WordPad, the texts of DDC data & table (128 bytes, hex
code) can be modified. If DDC TEXTS & HEX Table are completely
correct, it can be saved as .ddc flie to re-load it into DDC IC for DDC
Data application.
2. Click .Save
Step 7: Exit DDC program
Pull down the File menu and select Exit as shown in Fig. 25.
Step 5: Write DDC data
1. Configuration should be as Fig. 23. And press OK.
3. Click (Write EDID) icon from the tool bar to write DDC data.
Bring up "Writing 0%~100%, ready" a progressing bar on the left
down corner.
4. Turn off/on monitor
5. Press the OK button to bring up the OSD main manu.
6. Press the DOWN button to select PRODUCTION INFORMATION
press the OK button to confirm our selection.
