NO
Disconnect CN2301.
Is there the signal at each terminal of SC5601?
NO
Check the line between CN2301 and IC2301.
Mount C2301, C2306, C2313, C2317 and C2320 in place.
If no signal comes in, replace IC2301.
(When the 5V signal is fed to pins (7) and (21) of IC2301.)
Check the SUB_PC_5V line.
NO
Is the SUB_PC_5V signal fed to pins (7) and (21) of IC2301?
Are pins (2) (composite, output mute) and (13)
(component output mute) of IC2301 at "H" level?
("H": Mute)
YES
Check the PMUTE1, PMUTE2
and F_MUTE lines.

NO
Check the line between IC2301 and each terminal.
.
Disconnect the output coupling capacitors C2305, C2314, C2318
and C2321. If no signal comes out of the IC, replace this IC.
