Philips LC3141 Service Manual

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 also is 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.
