Introduction - Sony KZ-32TS1U Training Manual

Sony Plasma TV KZ-32TS1U/KZ-41TS1U Introduction
This training manual has been organized to provide a quick diagnosis of problems in Sony Plasma screen TV
models KZ-32TS1U and KZ-41TS1U. The circuitry in these two TV sets is similar, but the boards and plasma
panels are mounted differently.
Because the Plasma TV set is a new design concept, Chapter 1 will cover normal Plasma TV operation. The last
chapter will cover plasma principles / concepts (only necessary for background information).
Repairs to these TV models involve identifying and replacing a circuit board, the plasma panel or other parts
such as the fan or the on/off switch. This manual is divided into thirteen chapters:
