TSPP - CBG standup works in test but not in game?

[kevlar]

All of a sudden my CBG standup stopped working when playing but works fine in switch test mode. I thought maybe something else on the same row or column but everything else also seems to work fine also. I'm scratching my head a little here, any ideas? Would a faulty diode cause this?

Possibly or something else locked on / activating to mask CBG working...

Have a chat with me about it on Sunday if you haven't solved it by then!

Seems to be fixed now at least temporarily. I couldn't find anything wrong, made no sense at all, worked perfectly in test but not in game. I'd changed the CPU and display roms earlier in the day from v4 to v5 but I had played quite a few games with no problems since. Anyway clutching at straws I reset the machine to factory settings and it started working again, very strange. Fingers crossed.
