My GT 98 plays fine while I am hitting the ball but when another screen pops up, the screen becomes scrambled. You can kind of make out what it is suppose to say. I tried to clean and reseat the chips but it got worse. I assume a chip or two are bad. Anyone know which ones? I do not have a way to test the chips.

Thanks
 
Take 1 chip out at a time, clean it again, and reseat it, and see if it got worse or better. When you get to the one that makes it worse, or better, that's your bad chip :)
 
I forgot to run the test system. When I did the full GROM check, it said GRMC_1 03683415 is bad. When I did the board check, said GRMC_1 00587638 is bad. Anything I can do to fix this?

I was over and it looks like one of the GROMS are DOA. What are these PROMS? I read somewhere they're 27C040s but I'd like to verify before I attempt to obtain/burn a new chip for him.
