Hi,
Im currently troubleshooting a Capcom Bowling PCB. The issue is, the picture is not stable it jumps around, and won't stay steady. I'm testing this on a HAS supergun and have checked for grounding issues. All other boards test fine on this setup.
I tried swapping out my upscaler, and it's the same issue. The game itself plays fine, it's just the shakey screen. The setup includes the supergun, power supply, upscaler, and a flatcreen moniter. All other boards work fine on this setup. I have re seated the roms, tested voltage, checked for shorts.... What am i missing? I'm fairly new at this but have brought a few dead boards back to life. any thoughts or ideas??
