Check the IC7201 and their peripheral circuits.
Check the C

nal.
Is the video signal outputted from the component or
composite terminal J2401?
YES

Is the HDMI output set for anything other than 10
8
0P?
Set the HDMI output for anything other than 10
8
0P.
(If the HDMI output is set for 10
8
0P, the component and composite
signals are not outputted.)
Mount C2301, C2306, C2313, C2317 and C2320 in place.
If no signal comes in, replace IC2301.
(When the 5
V
signal is 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)
Disconnect the output coupling capacitors C2305, C2314, C231
8
and C2321. If no signal comes out of the IC, replace this IC.
Check the connected cable and its connection tightness.
Check also the input of connected T
V
set.
Disconnect C
N
2301.
Is there the signal at each terminal of SC5601?
Check the PMUTE1, PMUTE2
and F_MUTE lines.
Check IC2301 and its
peripheral circuits.
Or replace IC2301 as required.
