 RS33L JVC Service Manual by Kai-Uwe Wendlandt;
Very fast service, best quality of the service manual and the schematics
 VT-LC50EM HITACHI Service Manual by Henry Hyman;
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.
