Absolutely fantastic - thank you so much for this!! As luck would have it, I just imported one of these from Japan and was wondering if service information had surfaced yet.

Thank you for posting this information.

congrats on aquisition.
The only information I have that is useful for servicing is in the schematic posted. Reccommend you use a power adapter, not batteries as the battery caddy can easily break by now. so brittle.
If you are testing using the AV in port, I suggest feeding the video signal directly to the board as the ports on all of mine have been finnicky.
