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.

B6. Charging circuit As NiMH batteries may not be continuously loaded with a high charging current, the HQ564 has a timer IC (IC1). This IC controls TS4 in such a way that a current of 200 mA is supplied to the battery for about 8 hours, after which TS4 switches to a trickle charging current of 25 mA. D5 and D6 suppress high voltage peaks. This circuit is not required in the HQ563 because in this shaver the NiCd battery is continuously charged at 200 mA via R11. The value of R11 equals the internal resistance of TS4. B7. Battery The 4/5A NiCd battery of the HQ563 has a capacity of 1200mAH. The capacity of the AA NiMH battery of the HQ564 is 1100 mAH. B8. Motor The motor is of the permanent magnet type. Zener diode D4 suppresses high voltage peaks during shaving. Normally, this diode is placed between the motor solder tags to suppress radio interference (RIF) in the mains as well. As TS1 makes it impossible to switch the motor on when the shaver is connected to the mains, D4 is now placed on the PCB. GENERAL Some resistors are not indicated in the electrical diagram. These are resistors of 0 ½ which serve as jumpers across print tracks or as interconnectors between the layers of the double-layer PCB.
