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.

- Removing the OEL Unit
1. Apply hot air to the cable pins for the anode terminal using a blower used for removing a flat-packaged IC or something like that. When all the pins are peeling off from the P.C.board, pinch the cable with a pair of tweezers and remove it slowly from the P.C.board. (Fig.3) * Be careful not to remove other electrical parts when you use a blower. Especially, when hot air is appropriated to the VR1902 too much, the volume will destroy. * Flexible cable may not remove easily by transforming the Bosses by the hot air of the Blower. 2. Five tabs are extended until becoming straight in the direction of the arrow and then remove the Holder. (Fig.3) 3. Slowly set up the OEL Unit. At this time, the stress is prevented from hanging to flexible cable in the Cathode terminal. (Fig.4) 4. The Cathode terminal is removed according to the procedure same as the Anode terminal, and the OEL Unit is removed. (Fig.4) 5. Remove the Holder. (Remove after removing the Cathode terminal without fail.) (Fig.4)

- Installing the OEL Unit
1. Install the Holder in the OEL Unit. (Fig.5) 2. When soldering the flexible cable for the Cathode terminal on the P.C.board, use a pair of tweezers. First, insert the tips of tweezers into 2 holes in the flexible cable, then into the 2 holes in the P.C.board. (Fig.5) 3. Position the flexible cable on the P.C.board so that their lands touch each other. (Fig.5) 4. Apply solder to each pin of the flexible cable. (Fig.5) * Appropriate soldering iron lightly so that the stress should not hang to Flexible cable. 5. Lay down the OEL Unit. (Fig.5) 6. Install the Holder. (Fig.3) 7. When soldering the flexible cable for the Anode terminal on the P.C.board, first, insert the Bosses on the P.C.board into the 2 holes in the flexible cable. Then, take the same procedures 2 and 3 as that for the Cathode terminal to solder the cable pins. (Fig.3)
