Ivan Stewart's Super Off Road Track Pack Video Problem
I picked up a three player Ivan Stewart Off Road Machine with the track pack.
When I looked at it, it had some flaky boot up problems. The graphics were present, but the colors were off. It didn't boot to a play screen. After a few restarts, those cleared up and the game played fine. All of the controls worked, etc.
When I got the game home and started it, I had a really fun time playing. Everything seemed fine.
I took the pedals and steering wheel off and brought it into the basement. Everything booted up normally, but now the game field is off. The trucks follow the intended path, but the graphics have shifted up.
A previous posting had this same problem.

When I contacted dirtsarcade about how he resolved the problem, he said it had been so long ago, that he couldn't really remember what he did.
I ran the self test diagnostics and they all came back clear. Even the diagnostics that show the playing field are correctly aligned. However, when you actually play the game, the play fields are still off.
I pulled the PCBs and pressed in the chips to ensure that they were seated correctly, but did not take them out and reseat them. The PCB does not have any breaks, water damage or anything overtly wrong.
I put everything back together and booted it up. The diagnostics all checked out, but I still have the same problem.
My next thought is to pull the chips individually reseat them. I haven't seen any clear instructions on how to do this. I have chip puller, but would appreciate any advice on pulling them, cleaning, etc. Anything about this process that would prevent me from turning a somewhat working machine into a totally non working machine.
I'm not sure if this is even the right direction to go in. I doubt the power supply is flaky or I'd see all kinds of other problems besides this one, weird one. Many of the chips are marked "Track Pack," so I don't think it's a problem with a non-Track Pack board.
I really loved Off Road as a kid and would like to see this one work again.
Any advice is appreciated. Thanks much
