Manual is in German but complete. I needed this one to fix a long lasting problem with the internal PSU of the camera. Most of the capacitors begin to leak after a few years wich results in the inability to power on the camera. When you try to turn it on the power led flickers and the unit directly turns off. Thanks to this manual I was able to locate all bad cap's and to dis- and reassemble the camera without any problems.

We received the manual in a timely manner and it was exactly what we were expecting.

Very good scanning quality. All schematics are very legible. Worth every cent !

Excellent quality, very quick download turnaround, will definately use again.

2-2 Tracking system check. Check the TE waveform at pin 15 on IC1.
If the waveform shown in Figure 7-3-1 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 14, 15 and 20 on IC1, and CNS1A/B.
Yes
A normal jump operation cannot be completed or the beginning of the track cannot be found. Check the around pin 20 on IC1.
"Initialization" is not possible.
Data cannot be read. Check the VCO-PLL system.

Figure 7-3-1 2-3 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 7-3-2) No 2. The turntable doesn't rotate.
The spin driver circuit is OK. Yes
Check around pin 22 on IC1, pins 15 and 16 on IC2, and CNS3A/B.
