Thanks you very much for this "hard to find" service manual.
Will help a lot in repairing this tuner.
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.
