MV-1B with graphic issues

See graphic issues below. Cart slot and interconnectors are clean. Any chance it’s just the Video RAM chips? Or has the NEO-GRC-F died on this 1B board? Maybe the fujitsu curse strikes again

Looks like it could be an issue with the right side board interconnect.

I got a parts MV1B from a friend and tried swapping over the top board from it. Problem solved, graphics are good now.
