    Hello,

    This is the 256 x 64 Capcom dmd

    I have a Capcom large dmd which is showing garbage when powered on.

    I have verified the ribbon cable is installed correctly and I have also tried a brand new ribbon cable.

    I measured the voltages going to the display and they are correct 19vdc and 5vdc

    thanks

    Measured voltages on the dmd board and I get:

    Vsn = -107
    Vrw = -92.2
    Vcc = 4.95
    Vsp = 80.2
