TROUBLE SHOOTING T ABLE
(Continued)
No audio output
Yes
No
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
There is no voltage output at
EA connector.
No
No
No
Yes
Yes
Yes
Is EA connector disconnected
or loose?
Is R727 broken?
Is AC voltage (85-264V)
applied across the BA
connector?
Reconnect the EA connector.
There is a short-circuit along
the EA output line. Using a
tester, check the resistance
between each voltage line and
the ground.
No
Replace F1701.
Replace R727 or Q701.
