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.

A
- To reset the settings
When the EEPROM data is damaged due to failure, connect the TP302 to the ground. The initial settings stored in the monitor microcomputer will be automatically written into the EEPROM. Manually, you may adjust all the items on TEST1 and TEST2 modes to the adjustment values shown on the previous page.
- To operate the monitor only (see the adjustment points)
Connect the 14V, 7V and ground lines to the monitor pc board as shown on the wiring diagram. Turn on the power. 1) Apply the video signal to the test point around the center of the pc board. 2) For remote control output confirmation, use the test point near the monitor connector. 3) Confirm that the signal received by the remote control sensor (installed in the monitor) can be obtained at the pin 8 (MOREM) of the CN501.
B
- To operate the power supply unit only
Connect the power cord to the power supply unit. Switch the pin 10 (DSEN) of the CN757 to "L" and the pin 13 (SYSPWR) to "H". Check each power line, video signal, and remote control signal.
