Quoted from Isochronic_Frost:Off-topic but is there a thread somewhere on how to fix monitor collapse? I had this happen on a game a friend wanted me to look at. We were just standing there and boom! Picture just slowly fuzzed out and then shrunk into a pinprick.
I have little experience with arcades and I tapped out when that happened
The monitor probably needs the caps replaced. Most older monitors need this at some point. You can buy cap kits if you can identify the monitor.
