TROUBLE SHOOTING
(This is a basic trouble shooting.)

AUDIO PART

1. When time display OK and sound NG

or When S/PDIF 0K and anal

ogue NG.

Check DAC output
(10131 pin11/14).

OK

Tracking signal of
after DAC output.
Check MUTE signal.

Check (BCLK/
ASDATA/LRCLCIC131
pin 16/17/18).

Check lC131 pin1(27MHz)
and pin2(384FS).
Check lC131 power source
and peripheral circuit.
Check l0131 RESET/
control signal(pin6/7/8/9).

Check lC127
pin 105/106/107.

Check BCLK/ASDATA/
LRCLK signal line.
Check l0127 and

its peripheral.(|C127 NG)

Check IC127 peripheral.
(IC127 NG)

2. When time display NG and sound NG.

Exchange DVD:Loader.

OK

Loader NG.

Check IC127 peripheral.
(lC128 NG)

Check CD:CN810 pin2/3/4.

Check IC127 peripheral.
(IC127 NG)

Exchange loader.

Loader NG.

Exchange MPEG
p.w.board.

3. When S/PDIF NG and analogue OK.

Check optical module
and signal line.

Check lC127 peripheral.
(IC127 NG)

Check signal line
peripheralpattern
and parts.

4. When S/PDIF NG and analogue NG.

Check time display.

Check check 1

Check check 2

5. When pop noise (when usual operate.)

Check same output as
SPDIF and RCA.

YES

Loader NG

Check pop noise only
RCA output.

YES

Muting circuit trouble.
Check MUTE signal.

lC127 (MPEG) NG.

6. When pop noise (Power ONIOFF).
