Looks like a video RAM fault, perhaps with two or more of the 4461 VRAMs that hold palette data (U11-15, U29)

All video RAM is tested as part of the CPU board test though whether you can make out the results is another matter

This Smash TV repair log might be useful as it describes a similar fault on an identical PCB:
