CD-BK2100V

– 46 –

Is pin 35 (C2F) on IC2 "L"?

Yes

The HF waveform is normal and the time is displayed
normally, but no sound is produced. Or the sound
has dropouts.

(5) Others

There are too many error flags on a damaged disc which
makes error correction impossible.

Check again using a known good disc.

1. When playing at normal speed

Check the peripheral circuit at pin 37 (DOUT) on IC2 and
the waveform (Figure 46-2).

If OK, check the unit.

When a disc is loaded, start play operation.

(4) PLL system check

The HF waveform is normal, but the TOC data cannot be
read.

Check the PDO waveform. (Figure 46-1)

Check around pins 1~6 on IC2.
