Check which audio source (USB PLAY,
LINE, PHONO, or MIC) is not output from
the MASTER output.
Audio source USB PLAY
is not output.
No
No
Signal is output from neither
MASTER1 nor MASTER2.
Yes
The MUTE signal (TP7052) from
the MAIN Assy is "H."
No
The audio signal is
interrupted around the muting
transistors in the JACK2 Assy.
No
The MUTE signal (TP7052) from
the MAIN Assy is "H."
No
The audio signal is
interrupted around the muting
transistors in the MAIN Assy.
No
The audio signal is
interrupted around the muting
transistors in the JACK2 Assy.
No

memory device, hard disk, etc.) connected
Yes
to the USB A connector cannot be read."
or
"This unit cannot be recognized by
rekordbox."
Muting is activated. The MUTE circuit in the
Yes
MAIN Assy is in failure.
Replace the MAIN Assy.
Check Pins 22 and 24 (MASTER2), 26, 28,
30, 31 (MASTER1) of CN2403 on the MAIN
Assy.
If an audio waveform cannot be detected,
the audio circuit in the MAIN Assy is in failure.
Replace the MAIN Assy.
If an audio waveform is detected, check the
connection between the MAIN and JACK2
Assys.
The muting transistors in the JACK2 Assy are
Yes
defective, which disables audio signal output.
Replace Q5301 to Q5312 in the JACK2 Assy.
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.
Muting is activated. The MUTE circuit in the
Yes
MAIN Assy is in failure.
Replace the MAIN Assy.
The muting transistors in the MAIN Assy are
Yes
defective, which disables audio signal output.
Replace Q7201 and Q7206 in the MAIN Assy.
The muting transistors in the JACK2 Assy are
Yes
defective, which disables audio signal output.
Replace Q5401 to Q5404, Q5409 to Q5416
in the JACK2 Assy.
Check Pins 14 and 18 of CN5201 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 MAIN Assy may
be in failure. Replace the MAIN Assy.
If an audio waveform is detected, check
connections in the JACK2 Assy.
