4. Signal flow Diagram

This TV set Consist of main chip LA76814 controlled by Sanyo I

2

C bus and CPU LC863232A .

LA76814 is IC dedicated for NTSC, integrated following circuits inside: amplifying and detecting

in intermedium frequency, AFC, demodulating of sound intermedium frequency, brightness delay-line,
filtering and demodulating of color signal, processing of horizontal-vertical small signals.

TDA7056B is used for power amplifier of sound signal.
LA7840 is used for vertical power amplifier.
The detailed signal flow diagram is shown as follows:
