I have this hi-fi system for a long time and I need to repair some things. Founding this manual will be very helpfull :)
 ;
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.

10 SOLUTIONS IN CASE OF PROBLEMS DURING THE TESTS
Under no circumstances the phone have to be disassembled (Except Customizations Parts) to fix a defect detected during the test procedure on �LEVEL 1". 10.1 The phone does not switch on.
- Check the tactile feeling of the �ON/OFF� button. - Remove the battery. Check that both the connectors of the phone and those of the battery are not damaged. - Clean the connectors. - Plug the battery again, making sure that it is securely fitted. Charge the mobile until the icon has stopped flashing. Then unplug from the charger and attempt to switch the mobile on. If it still does not switch on, try to fix the mobile. If the failure can�t be found out then swap the board. 10.2 Charge does not start or no detection of the charger. (refer to chapter 8.3)
- Check the charger contacts for dust or missing pins. - Check the mobile connector. - Remove the battery. Check that both the connectors of the phone and those of the battery are not damaged. - Check the charger individually with a reference mobile. If the charger works properly try to charge the customer mobile with a reference battery. If neither of the battery and the charger can be incriminated, swap the board. 10.3 The display shows �No SIM card. Please insert your SIM card.� or �SIM FAILURE�
- If the SIM card cannot be inserted, check for any foreign part and try to remove it. Check the Sim holder. - Check the SIM Connector. All the contacts must be at the same level. Make sure that there is no dust on the connector contacts and the SIM card contacts. If the SIM Card connector is defective swap the Board. 10.4 Display problems
Contrast, icons and matrix of the display can be checked with the test SIM card by pressing keys �5�, �6� and �7� . If everything works in test configuration that means that a phone setting is disabled or does not suit well. It can be solved in the phone menu. Otherwise swap the board.
