Very fast and perfect delivery. Clear and well scanned. A lot of work professionally realized.
Again thak you a lot
 ;
This manual is accurate and of high quality. It is only volume 2 of the service manual. This is schematic, parts lists, and exploded mechanical drawings. The theory of operation and the diss-assembly instructions are in volume 1. The unit can be tricky to dis-assemble portions of so the volume 1 manual can be important. The product description of the manual is accurate but it does not say anything about volume 1 and the image of the front page does clearly say Volume 2.

Wellll again thank you very much fast and effective. Clear and well done for such an old TV!!!!
CD-BK2100V
Check the TE waveform at pin 18 on IC1.
If the waveform shown in Figure 45-1 appears and soon after NO DISC appears. No "Initialization" is possible, but play is not possible. No Yes The tracking servo is not activated. Check the peripheral circuits at pins 18 and 19 on IC1, pin 23 on IC2, and CNS1A/B.
Yes
A normal jump operation cannot be completed or the beginning of the track cannot be found. Check the around pin 23 on IC2.
"Initialization" is not possible.
Data cannot be read. Check the VCO-PLL system.

Figure 45-1 (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 45-2) Yes No
The spin driver circuit is OK.
2. The turntable doesn't rotate.
Check around pin 25 on IC2, pins 15 and 16 on IC3, and CNS3A/B.
