Introduction; Overview; Ctv-30 Objectives - Sony KV-13FS100 Product & Training Manual

Overview

This course will cover the new BA-6 chassis. The USA model sizes for the BA-6 chassis are 13", 20" and 24".
This chassis has major circuit changes from the BA-5 chassis, the main one being the integration of Syscon, YC
Jungle and Comb Filter into one IC package (called One-Chip). Other changes are in the Power Supply (Main
and Standby) and the Audio section. The Vertical and Horizontal deflection section are similar to previous
chassis's except for the Horizontal Output transistor, which is a new design. Although this single chip design may
seem to eliminate a large portion of circuit troubleshooting, there are still discreet circuits and external ICs that
can fail. In addition, when the unit becomes defective, a good understanding of the One-Chip IC functions will be
needed to determine if the problem is in the One-Chip IC or in external circuits.

CTV-30 Objectives

Define the One-Chip design.
•
Provide a Theory of Operations (Waveforms and Voltages) and Troubleshooting Tips for each major
section of the BA-6 chassis.
•
Discuss unit Self-Diagnostic functions and how they can assist in troubleshooting.
