Are audio signals output to U2100 25pin(left
channel) and 17pin(right channel)when an audio
signal of 1 kHz 0 dBV is input externally to the CD
input?
However, current output.
Check the input signal from N232 to U2100 and
their periphery, and service it if detective.
When the input signal is correct, U2100 is replaced.
Are the audio signals outputted to 7pin and 1pin of
U2101(Lch), U2102(Rch), and U2103(L/Rch)?
Check periphery circuit of U2101,U2102,U2103
from 25pin
, 17pin of U2100, and service it if
defective. When the periphery circuit is correct,
U2101,U2102 or U2103 is replaced.
Are the audio signals outputted to 7pin(COLD) and
1pin(HOT) of U2105(Lch), U2106(Rch)?
Check periphery circuit of U2105,U2106 from 7pin
,1pin of U2103, and service it if defective. When
the periphery circuit is correct, U2105 or U2106 is
replaced.
Is 20pin of N232 (MUTE control signal)H, and has
been the Q2164 collector (MUTE drive signal)
L(-15V)?
Check Q2110,Q2112,Q2113,Q2115 and the
periphery circuit, and service it if defective.
Check periphery circuit of K2103,K2102 from 7pin,
1pin of U2105,U2106 , and replace it if defective.
