Great scan but please note that it is entirely in GERMAN.
 ;
High quality scan of the manual, very quick and easy download and very important, a truly honest price. thanks

Minden rendben, de két megjegyzés, az ábrák nehezen kivehetők és a fizetés után 24 órát kell várni a letöltésre.
;
Manual correct, and complete. Downloads cleanly. Format of manual was presumably difficult to PDF to A4, but works reasonably well.
;
This was a hard to find manual. When I did find it , some sites wanted way too much for the file.
Owner-manual .com had it for a really reasonable price. Not only that but it was sent very quickly and was a quality scanned document, unlike some others I purchased from a different site.
Good job guys!!

� Playback can only be performed when a disc is loaded.
Is the Focus servo active? (Can you hear it working?) Yes Yes Does the DRF signal change from "L" to "H"? Yes Yes Is HF waveform normal (see the Fig.37-1, 2)? Yes Check the tracking system. Waveform is unstable.

No
Check the laser diode driver. Check the area around IC1(16) - (21) (focus servo circuit).
No
If the disc is not turning, the DRF should not change to "H".
Check the spin system.
No
Level is abnormal. Yes
Check the periphery of IC1 pins 41 and 42.
Check the spin system.

Check waveform of IC1 pin 7 (TE). The waveform shown in Fig. 37-3 appears, and nodisc state appears soon. Tracking servo is inoperative. Yes Check the periphery of IC 1 pin 8 to pin 15, and IC 3 to CNP2.
Yes
Play is possible in TEST mode.
