Check the input, the switching circuit
of IC403 and IC404, and their
peripheral circuit.
Are there audio signal inputs at pins
(2) and (23) of IC301?
Yes
No
Check IC302 and its peripheral
circuits.
Are there audio signal outputs at pins
(3) and (6) of IC302?
Check IC302 and its peripheral
circuits, and the SP connectors and
speakers.
If the voltage at pin (7) of IC302 is not
as specified, check Q302, Q303 and
their peripheral circuits.
Checkig the Power Unit
