Newbie to troubleshooting pins. Just bought a nice JP and the DMD works but has a lot of wavy action goin on, like all the animations are over brighting causing like a ghost effect. When between or no animations it looks like distortion waves going across the screen. The previous owner said he replaced the power supply board located in the back box from Mad Amusements because it was blowing fuses. Ever since he did that, it fixed the fuse issue but started the dmd issue. Any ideas to what is causing this and how do I fix? I have the old board and I could send it to Mad Amusements to have the original fixed I guess but is there a easier/cheaper solution? Thanks for the help.

Quoted from Borygard:

Sounds like over voltage from the high voltage section of the power supply. You will destroy the DMD if you continue to run it like that. Check voltages into the DMD to confirm.

How do I do that and what should the voltage be? Can this be adjusted or is it a flaw on the board? Thanks!
