Good site, works ok and you get what you order, no problems experienced, got my manual within a day. A++++

Original well scanned manual. Got the job done. Microwave problem found & corrected. For $5 and a new magnitron from ebay, it was a cheap and good the first shot fix. Electrical schematics allowed me to mage sure every thing else was ok before cutting and order for parts. Hard to live without.

I was very skeptical of this website, I have never downloaded manuals before. I put it on the AMEX and payed through Paypal to ensure protection. I got the manual exactly as described and now I can replace the filter capacitor for this amp. Great Price, others selling for 12.99 or more and this is the same manual. I will search out this website for other manuals. Thank you

Manual was reasonably easy to follow. I am not an engineer or know much about electronics but with the manuals help I was able to figure out the problem, identify the part required for the repair. Replacement part cost around $30. Whilst replacing the part I was telling myself, "this aint gonna work cos it seems far too easy". Took about 15 minutes to do and my plasma TV works a treat. Would never have been able to do this without the service manual.

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.
