At what voltage can you start causing damage to boards?
The reason I ask is I had a known good PSU (cheap Chinese brand) powered on my game, nothing displayed but a white screen. Switched off the game checked the PSU and measured a voltage of 6.4v. Attempted to turn it down and at its lowest it was at 6.04v. I swapped out with two known working PSU's (Peter Chou's) and at their lowest they are around the same, one at 6.1v the other at 6.4v.
It can't be a coincidence that all three PSU's are at the same voltage, perhaps a spike in the house? Could something in the cabinet be causing the problem? Everything was working fine yesterday, the only change has been powering off to swap games.
Lastly, what's the possibility I have damaged my game when I first noticed the problem? The cab would have been on for 10 seconds before I switched it off.
Any recommendations to troubleshoot? I don't want to fire it up with anything running in it until the voltage is back down to a suitable level.
