It does not appear to be worth fixing.
That is sure what it sounds like.
We quit doing the dance to try to find native 12 tv and video components as they are getting harder and harder to find. About all there is now are the "trucker" tvs which have gotten better but still most aren't all that nice. They are about the only choice if you want a smaller size though. Almost everything now is 19" of more.
We put in a 120watt PSW inverter to run the tv and dvd player and found we actually use right about the same amount of power as when we ran the 12v stuff with a 12v stabilizer. Now we can put in any 110v unit if we need to.
