CD-G10000/CP-G10000S
7 – 3
Check the TE waveform at pin 15 on IC1.
(2) Focus-HF system check.
If the waveform shown in Figure 4 appears and soon after NO
DISC appears?
Yes
The tracking servo is not activated.
Check the peripheral circuits at pins 16, 17 and 22 on IC1, and
FFC1.
No
“Initialization” is possible, but play is not possible?
Yes
A normal jump operation cannot be completed or the beginning
of the track cannot be found.
Check the around pin 22 on IC1.
No
“Initialization” is not possible.
Data cannot be read. Check the VCO-PLL (Pin76~80 on IC1)
system.

(3) Spin system check.
Press the OPEN/CLOSE switch without inserting a disc, and
then try starting the play operation.
1. The turntable rotates a little?
(Waveform drawing Figure 5)
Yes
The spin driver circuit is OK.
No
2. The turntable doesn't rotate.
Check around pin 24 on IC1, pins 3 and 4 on IC2, and CNS3A/
CNS3B.
