It's an Orion TVDVD092 9" tv/dvd combo that I use in my camper. IIRC it was connected to DC backwords awhile back, meaning - and + were reversed, at least that's what I think.
Fuses are good and nothing is visibly fried, no cold joints either. Plugging it in to 12v I get power all over the main board that power is connected to, 12v though. With it plugged into AC I get 40V at the same points. I cannot find a schematic anywhere so I'm shooting in the dark here.
I've checked out a few similar sets at local thrift shops only to find the same problem, nothing with DC. Seems a common problem. Not sure if anyone can help but if you have any ideas I'm all ears. TIA
