The tracking servo is not activated.
Check the peripheral circuits at pins 50, 51, 48, 49 on IC1 and 
FFC1.
(2) Tracking system check.
If the waveform shown in Figure 4 appears and soon after NO 
DISC appears ?
Check the TE waveform at pin 63 on IC1.
"Initialization" is possible, but play is not possible ?
No
Yes
A normal jump operation cannot be completed or the begining of 
the track cannot be found.
Check the around pin 49 on IC1.
Yes
"Initialization" is not possible.
No
When a disc is loaded, start play operation.
The RF waveform is normal, but the TOC data cannot be read.
Check the PLL waveform. (Figure 6)
Check around pins 73 ~ 76 on IC1.
Data cannot be read. Check the VCO - PLL (Pin no. 73 ~ 76) 
on IC1 system.
(3) Spin system check.
(4) PLL 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
2. The turntable does not rotate.
The spin driver circuit is OK.
Check around pin 50 on IC1, pins 1 and 2 on CNP2.
No
