Important Safety Notice
Proper service and repair is important to the safe,
reliable operation of all Philips Consumer Electronics
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, Philips Consumer
Electronics Company will be referred to as Philips.
WARNING
Critical components having special safety
characteristics are identified with a
by the Ref. No.
in the 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.
* Broken Line
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
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 with any sharp
objects, such as pencil or pen as 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 are
grounded through wrist band.
- 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 become dirty, please wipe it
off with a soft material. (Cleaning with a dirty or
rough cloth may damage the panel.)
