Complete service manual, was very helpful in repairing this tapedeck.Thanks.

The service manual was a copy of the original from Wirlpool. The quality was good, all neccecary information was available including the service-codenumbers, so I could order the right part to be replaced for repair.
Downloding was no probem after the payment.
Thanks for the service!

Good,readable manual. I found other manuals that were not readable when it came to part ID, but the one downloaded from owner-manual.com was better than expected. I will do buisness with owner-manual.com again.

The manual is well organized and is easy to read. The chapters are following normal way to proceed.

(2) Tracking system check. Check the TE waveform at pin 18 on IC1.
If the waveform shown in Figure 47-1 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 47-1 (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 47-2) 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.
