I just got a tournament cyberball and it has a board problem. Both sides are working and It does not show any errors in the test screen.

The colors look off on one side. I swapped most of the socketed chips with a regular cyberball and no change.

I don't think it can be a rom error as 1 side looks fine.. Its a dual 68000 board. Any chance one of thr 68000's is bad? Any ideas?

Here are some screen shots. 1st pic is side 1 2nd pic is side 2.

I have a spare board, but I would like to try to fix this one. If someone is interested in tournament cyberball, I intend to sell it when its repaired.
