Important Safety Notice
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 design ed 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

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 ha zardous conseq uences of each way. Consequently , Philips ha s
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, Philips Company will be referred to as Philips.
WARNING
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.
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 SERVICE MANUAL.
Take care during handling the LCD module with backlight unit
-Must mount the module using mounting holes arranged in four corners.
-Do not press on the panel, edge of the frame strongly or electric shock as this will result in damage to the screen.
-Do not scratch or press on the panel wi th any sharp object s, su ch as pen cil or pen a s this may result in damage to
the
panel.
-Protect the module from the ESD as it may damage the electronic circuit (C-MOS).
-Make certain that treatment person’s body is grounded through wristband.
-Do not leave the module in high temperature and in areas of high humidity for a long time.
-Avoid contact with water as it may a short circuit within the module.
-If the surface of panel becomes dirty, please wipe it off with a soft material. (Cleaning with a dirty or rough cloth
may damage the panel.)
