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.

2) Push in the optical sensor disc until it clicks in the same manner as when setting a disc.
In the POWER Adjustment, operate the drive with the disc cover left open. During the adjustment, be sure to observe the following precautions: 1) Set the optical sensor disc correctly. 2) Keep the distance of more than 30 cm apart from the camcoder. 3) Work on the LCD screen side of the camcoder (opposite side of the drive). Note: Laser light of the equipment is focused by the object lens in the optical pick-up so that the light focuses on the reflection surface of the disc Therefore, be sure to keep your eyes more then 30 cm apart from the object lens when you check the emission of laser diode
