    The two position ribbon from the MPU to the DMD controller is backwards. The red stripe position on the ribbon should match the other ribbon that connects from MPU to FlipTronics to Sound to DMD controller.

    Flip that ribbon and let’s see what happens.

    Quoted from PinballManiac40:

    Time to gave the board repaired. Anyone you know works on boards and can change BR2, C2, C7 and the other capacitor above F101 to F105?

    PinballManiac40 i think you might mean BR2 (maybe), C2, C4, and C5, right?

    Quoted from PinRetail:

    I saw that too, but it looks like the ribbon is plugged in backward on both ends, which won't cause a problem.
    It's still good advice... plug the darned cables in right!
    The tiny '2' on the display board is an indication for the stripe side of the cable should be on the top. On the CPU your stripe should be to the left to match the other cable.

    Yep. You are right.
    Oops.

    C5 and C11 look a little "domed" to me.
    C5 doesn't dome usually.
    But C11 can dome if coil and flasher connectors are misplaced.
