I have a spare parts board if needed. Where should I look first for fixing a Sega 16b with known good rom board that has a scrolling green screen that locks up? If I am fast I can hear hear the game start with music but it glitches in a loop. I think I was able to get into test 1 time but haven't been able to repeat. Attached is a screenshot. I validated continuity on all rom board pins to main board. The rom board is ESWAT. I tried a working Shinobi rom board and that one does nothing.
