I have this hi-fi system for a long time and I need to repair some things. Founding this manual will be very helpfull :)
 ;
It is pretty good. The schematics were covered all components, the manual also provide the parts list . It's useful for the trouble shooting.
;
Very fast service, best quality of the service manual and the schematics
;
This service manual of the old video cassette recorder VT-LC50EM is very good readable even the tiniest numbers (i.e. IC-pins). The circuits are very clear. Many details of the schematic are very good described but in GERMAN language. Many schematic details - but complete at all. Common background information of several details are enclosed and physical knowledge of the TFT liquid crystal display for example. The manual lacks PCB drawings. If you understand german I would recommend this manual for you.

Hi, this is a very clear manual, nice copy, not quite up to the standard of the very best available but better than many others. I think the price was especially fair for a hard to find manual and I would certainly use this manual seller again. Recommended.
DV-535
WARNING! THE AEL(ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1 BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR CLASS 1. A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS.
LASER DIODE CHARACTERISTICS FOR DVD : MAXIMUM OUTPUT POWER : 5 mW WAVELENGTH : 655 nm FOR CD : MAXIMUM OUTPUT POWER : 5mW WAVELENGTH : 785 nm
LABEL CHECK
WYXJ, WYXJ/SP, WVXJ and WYXQ types
(Printed on the Rear Panel)
Additional Laser Caution 1. Inside detection switch (S201 on the SMEB assy) and loadingstatus detection switch (S101 on the LOAB assy) are detected by the microprocessor (IC11 in the DVDM assy). � To permit the laser diode to oscillate, it is required to set the inside detection switch for the inside position (S201 : ON) and to set the loading-status detection switch for the clamp position (the center terminal of S101 is shorted to +5V). The 650 nm laser diode for DVD oscillation will continue if pin 19 of IC1 is shorted to +5V (fault condition) in the DVDM assy. The 780 nm laser diode for CD oscillates if pin 20 of IC1 is shorted to +5V in the DVDM assy. In the test mode � , the laser diode oscillates when microprocessor detects a PLAY signal, or when the PLAY key is pressed (S706 ON in the KEYB assy), with the above requirements satisfied. 2. When the cover is open, close viewing through the objective lens with the naked eye will cause exposure to the laser beam. � : See page 49.
