I've gotten my cab put back together. My arcadeVGA installed and working fine on my computer monitor. I go to hook it up to my arcade monitor and nothing happens. Increased the screen voltage on the flyback and got some kind of picture but it's just green bars and static. I tried tweaking the H and V potentiometers but didn't seem to affect anything. I'm not sure if this just needs tweaking or the signal just isn't getting through. Any thoughts?
