This Service Manual was exactly what I needed to repair my Philips TV. The purchase was convenient and I received the manual at the same day I paid for it.
Very helpful and complete manual. Maybe only one negative is schematics have sometimes unreadable name of the parts. But it's not a big problem.

How to Replace the Lithium Battery
Replacement Procedure
1. Remove the MAIN PCB. (Refer to Disassembly Procedures.) 2. Remove the Lithium battery (Ref. No. �Z9101� at component side of MAIN PCB) and then replace it into new one.
NOTE: This Lithium battery is a critical component. (Type No.: ML-421S/ZT Manufactured by Matsushita Battery Industrial Co.,Ltd.) It must never be subjected to excessive heat or discharge. It must therefore only be fitted in requirement designed specifically for its use. Replacement batteries must be of same type and manufacture. They must be fitted in the same manner and location as the original battery, with the correct polarity contacts observed. Do not attempt to re-charge the old battery or re-use it for any other purpose. It should be disposed of in waste products destined for burial rather than incineration.
