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.

This schema available for me in good condition. I would highly recommend.

Voltage level is measured at the following condition. 1. Plug the power cord in AC outlet. 2. Mode switch position : REG, display 0.00 3. Put in the memory protection batteries. 4. Plug out : Plug out the power cord , the memory protection batteries in.
6-2. Reset circuit

S-80728AN
When the voltage level at the pin No.17 of CPU is not stable, CPU does not work properly. To make a stable voltage, the reset IC(S-80728AN) is used for this circuit. In case the voltage level of VDD becomes down output terminof reset IC is out the stable voltage.
