First off, thank you for the information about the monitor. I was checking out some of the burn-in on the front, and it actually has an outline of a pac-maze. I would have never even guessed a Nintendo cab.
Going by what you said about the flyback though, this is what I'm facing right now ... and it looks like everything you talked about. ( See Below )
Is it safe to say this monitor might be better suited for a trip to the dump, or might a TV repair shop actually have a chance of fixing her up? That was one of the first things I noticed on this monitor, but I figured it was easily fixed.

You also mention 100v , what exactly does that mean ? Would I need a special wiring config. just to use for say ... a mame cab?
Thank you again,
Mike
