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.

DISASSEMBLY FOR REPAIR
How to attach the tray and the clamper.
1. Turn the traverse gear A in the direction of the arrow in the drawing so that the traverse unit will reach the highest position.
Assembling and Disassembling the Optical Pickup
The optical pickup can be damaged by static electricity from your body. Be sure to take static electricity countermeasures when working around the optical pickup. Handling the Optical Pickup 1. The optical pickup is an extremely high-precision mechanism. Do not subject it to strong damage. 2. Testers cannot be used to check the laser diode of the optical pickup. The power supply in side the tester can easily damage the laser diode. 3. Take care when handling the flexible cable because excessive force can cause it to break. 4. To preserve the quality of the optical pickup replacement parts during transport and installation, the terminals of the laser diode are short-circuited. After replacing the parts, use the proper procedure to return the laser diode to its original condition. Static Electricity Countermeasures The laser diode inside the traverse unit (optical pickup ) can be damaged by static electricity from your body. Be sure to take static electricity countermeasures when working around the optical pickup. Static Electricity Countermeasure Methods 1. Ground yourself Use an anti-static wrist strap to discharge static electricity from your body. 2. Ground the workbench Lay a conductive material (sheet) or steel sheet on the surface where the traverse unit (optical pickup)is to be placed, then ground the sheet. Assembling the Optical Pickup 1. Insert a flexible cable in the arrow direction in the drawing. 2. Cut the flexible cable.
