The MUTE signal (TP7052) from
the MAI N Assy is "H."
N o HP output
Muting is activated. The MUTE circuit in the
MAI
N Assy is in failure.
Replace the MAI N Assy.
Yes
Is switching among DECK, LI N E,
and PHO N O possible?
Are the CH level indicators lit?
Check the indication on the
LCD if switching between LI N E and
PHO N O is properly made.
Are the waveforms detected at Pins 16,
20 of C N 5101 inthe JACK1 Assy?
Are the waveforms detected at Pins 1,
4 of C N 5201 inthe JACK2 Assy?
The LI N E/PHO N O audio signal is not output.
See " N o operation with keys (switches)."
Yes
Check the connection between the switch in
the JACK1, JACK2 Assemblies and the
MAI
N Assy.
Check if S5101 and S5201 can be switched.
N o
The muting transistors in the MAI N Assy are
defective, which disables audio signal output.
Replace Q7201 and Q7206 in the MAI
N Assy.
Yes
The muting transistors in the HPJB Assy are
defective, which disables audio signal output.
Replace Q5901 and Q5902 in the HPJB Assy.
Yes
The LI N E/PHO N O input circuits are normal.
See also " N o MASTER output" and " N o HP
output."
If the problem is not resolved after the above
corrections, the MAI
N Assy may be in failure.
Replace it.
Check if S W _I N 1, S W _I N 2 operates
properly, referring to "10.46 W A V EFORMS
h
: Audio I N PUT/S W AMP switching."
Yes
Check the connections between the JAC1,
JACK2 and MAI
N Assys.
If the connections are OK, then audio data
are not input to I.MX. As this indicates that
the MAI
N Assy is in failure, replace it.
Yes
Yes
N o
N o Check Pins 3 and 5 of JP5901 in the HPJB
Assy.
If an audio waveform cannot be detected,
check the connecting cable. If the cable is
OK, the audio circuit in the MAI
N Assy may
be in failure. Replace the MAI N Assy.
If an audio waveform is detected, check
connections in the HPJB Assy.
N o Check for a point where the audio signal is
interrupted:
Channel 1: Check the periphery of IC5101,
and IC5102. If they are OK, then replace the
OP amplifiers (IC5101and IC5102 in the
JAC1 Assy).
Channel 2: Check the periphery of IC5201,
and IC5202. If they are OK, then replace the
OP amplifiers (IC5201and IC5202 in the
JAC2 Assy).

A
The audio signal is
interrupted around the muting
transistors in the MAI N Assy.
The audio signal is
interrupted around the muting
transistors in the HPJB Assy.
