CD-G10000/CP-G10000S
7 – 4
The HF waveform is normal and the time is displayed normally,
but no sound is produced. Or the sound has dropouts.
(4) PLL system check.
When a disc is loaded, start play operation.
The HF waveform is normal, but the TOC data cannot be read.
Check the PDO waveform. (Figure 6)
Check around pins 76~80 on IC1.

(5) Others.
Is pin 69 (C2F) on IC1 “L” ?
No
There are too many error flags on a damaged disc which makes
error correction impossible.
Yes
1. When playing at normal speed.
Check the peripheral circuit at pin 39 (DOUT) on IC1 and the
waveform (Figure 7).
Check again using a known good disc.
If OK, Check the unit.
