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.

Thanks for this "hard to find" service manual.
I apreciate the good quality of scanning and the pages scanned in A3 format.

Controlling (automatic) the Fluorescent Lamp Intensity (ALVC control)
Outline When pre-activation pre-heating is over, the microprocessor (QlOl) on the DC controller PCB instructs the microprocessor (Q501) on the composite power supply PCB to generate the scanning lamp on signal (FLAON*). At this time, the fluorescent lamp driver circuit operates to apply the output of the primary side of the main transformer (T102) to both ends of the scanning lamp so as to turn on the scanning lamp at a high frequency. Controlling the Intensity of the Scanning Lamp a. Outline The intensity of the scanning lamp is controlled by the microprocessor (Q501) on the composite power supply PCB. The intensity sensor checks the intensity of the scanning lamp and generates activation power to suit the intensity. The microprocessor, on the other hand, finds out the intensity of the scanning lamp based on the activation power to send the scanning lamp on signal (FLON*) to the on control circuit. Intensity Lower Than the Specified Value The microprocessor increases the duty ratio of the scanning lamp on signal (FLON*) sent to the fluorescent lamp driver. The fluorescent lamp driver, in turn, increases the current flowing to the scanning lamp, thereby increasing the intensity of the scanning lamp. Intensity Higher Than the Specified Value The microprocessor decreases the duty ratio of the scanning lamp on signal (FLON*) sent to the fluorescent lamp driver. The fluorescent lamp driver, in turn, decreases the current flowing to the scanning lamp, thereby decreasing the intensity of the scanning lamp. c. b. 4.

The ,copier executes ALVC control in which the ON voltage of the scanning lamp is automatitally corrected to prevent changes in the copy images caused by deterioration of the photosensitive drum.
