    No display on regular WPC dmd

    Hi all
    Iíve taken the color dmd out of my Indianapolis 500 and replaced it with a regular dmd
    The color dmd worked fine and the regular dmd has no display.
    Iíve tried 2 different dmd screens that I know are working.
    I donít get why this would happen.
    Can anyone give me any advice?

    Dmd driver board has a blown fuse or high voltage issue. Colour dmd doesn't use the high voltage section of the dmd driver board.

    Try swapping dmd driver board with another machine to verify this is the issue.

    Colourdmd doesn’t use the high voltage but the plasma does
    Perhaps a blown fuse or the high voltage section has a fault
    Have you checked the voltages at the connector?

    Thanks Rob. Went to the JD and realised it had a purple and white wired plug that the other machine didnít have. Found that and bingo! Thanks mate!!!

    Did you reconnected the high voltage cable? This cable is removed & not used on a ColorDmD.
    Dang just read you found the cable missing.
