Proper service and repair is important to the safe,
reliable operation of all Philips Consumer Electronics

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 Take care during handling the LCD module with backlight
