Is there any chance that one of you might have a repair manual or schematic for the SONY KV-5200 (1979 colour NTSC portable television)?
I have one that does not power on, at all, and it is a beast to take apart. Before I tear it down, it;d be nice to know where to look for faults. This telly use DC12V or AC120V, so perhaps something in the switching circuit is stuck? It also had a battery pack from the factory, but I see no reason why it would not work if there was no battery and it was not set in charging mode; although perhaps the charging mode circuit is stuck?
Eit: Found one by SAMS.
