Quoted from inhomearcades:Couldn't you just adjust the +5v on the chassis itself or does that model not have that option? I usually have to do that on some of the arcades prior to rejuvenation.
I'm pretty sure the +5v is for the board logic. It wouldn't amplify the video signal. Increasing the board logic voltage would just cause damage on the boards.
Quoted from inhomearcades:Hmm interesting. Its been something we have done for years and it has a direct impact on the video signal. Makes pictures come alive again for sure. Also a trick was taking the b+ going to the neck board and wrapping it around the flyback, boosted picture as well but that was a worst case on the road trick to fix something until we could pull the monitor.
I was making a few assumptions about the system, so I'll defer to your experience with the machine. The video did a good job explaining what the signal voltage was and what it gets boosted to.
