Daytona USA Model 2, all 4 TGPs bad?

[Tailsnic Retroworks]

Hi, I have a partial working Daytona USA 1 board, which has no 3D and the test says all of the 4 TGPs are BAD. I'm new in this system board, so I'm learning.

I don't think those 4 customs of the CPU board are broken. It must be another component between them.

If anyone knows where to look first, I would be very thankful.

I'm trying to find any information about this error. I'm not buying the 4 TGPs are down. There must be something controlling them.
