Trouble in the audio system
N
o MASTER output
Muting is activated. The MUTE circuit in the
MAI
N
Assy is in failure.
Replace the MAI
N
Assy.
See also "Data from the device (USB
memory device, hard disk, etc.) connected
to the USB A connector cannot be read."

Check which audio source (USB PLAY,
LI

E, PHO
N
O, or MIC) is not output from
the MASTER output.
Audio source USB PLAY
is not output.
Signal is output from neither
MASTER1 nor MASTER2.

The muting transistors in the JACK2 Assy are
defective, which disables audio signal output.
Replace Q5301 to Q5312 in the JACK2 Assy.

Assy.
If an audio waveform cannot be detected,
the audio circuit in the MAI
N
Assy is in failure.
Replace the MAI
N
Assy.
If an audio waveform is detected, check the
connection between the MAI
N
and JACK2
Assys.
N

Check for a point in the JACK2 Assy where the
audio signal is interrupted.
· If only MASTER 1 has no audio signal output,
check the periphery of IC5301/IC5302. If no
abnormality is found, then the OP amplifiers
(IC5301/IC5302) in the JACK2 Assy must be
replaced.
• If only MASTER2 has no audio signal
output, check if the capacitor or resistor is
damaged or if any circuit is open.

The muting transistors in the JACK2 Assy are
defective, which disables audio signal output.
Replace Q5401 to Q5404, Q5409 to Q5416
in the JACK2 Assy.

If an audio waveform cannot be detected,
check the connecting cable. If the cable is
OK, the audio circuit in the MAI

If an audio waveform is detected, check
connections in the JACK2 Assy.
