Just picked up another Super Off Road. Pretty good score for not having any pictures posted on the ad. Seller said view email that the machine had picture issues. Game worked great for two years then the picture started acting goofy when the moved it to a new location. His theory was it needed a new cap kit. The price seemed worth taking the risk on so I made the 30 mile drive to check out the machine.

When I arrived he plugged in the machine and game boots up with a garbled picture. I could tell right off the bat that the issue had to be with the board and not with the monitor. To my surprise it was a Track Pack edition so I figured it was worth taking a chance on. Was able to talk the seller down to 50 bucks and on my way I went.

When I got the machine back to my shop I swapped out the boards with a working Off Road board and everything works fine so the issue is definitely with the board. The picture is garbled up. The game and sound works. You can still play the game just the picture looks all goofy. It doesnt freeze, black out, pause, or shut down.

I am hoping its just a bad chip? I have zero experience working on these boards. Anyone come across this? Sorry for the bad pictures. I will try to post some more tomorrow. Currently 113 degrees in my shop. Ugghhh....

I would make sure the chips are seated well. Maybe just press on the tops of the socketed chips and see if that makes a difference.

Yeah I was going to try that. Didnt know if anyone knew of a specific chip that might cause this. I saw a few "dead" boards for sale. Optimistic that maybe I could pull salvageable parts off of a dead board.

Wishful thinking most likely...
 
I got mine working by taking a second boardset (which was crap with acid damage) and swapped the bottom board of the acid damaged set (bottom board didn't have damage) and put it with my top board and I was 100% golden at that point.

after you reseat, all of the chips, maybe pick up a couple of extra non working board sets and see if some swapping around will help.

NOBODY works on these.
