Hey guys

I reset the ribbon cables on my working screen yesterday in hopes to fix one line that was out. Turned the game back on and didn't look at the screen right away but after a few minutes noticed that the screen was black I didn't know what from.

Now I notice I reset the smaller of the 2 ribbon cables on backwards I had the red line on pin 13 not 1

My bad I switched it back and the screen is still black.

Tryd to check voltage coming to the DMD and it was all over the place but then would rest at 4.9 so I should be all good there.

Any ideas what to check and how to fix it.

I tryd a different ribbon cable from another game and it didn't work so it's not the ribbon cable.

I looked at the DMD boards and I don't see anything on them

Bump please help

I got 5v with the power to the DMD board

The pins are on correctly now. That's how I got into this mess putting one of the ribbon cables on backwards

Can I test the DMD in a Williams game? I don't have another data east.

I have a sega batman forever but not sure if that will work with the larger DMD

Ok got the DMD working! Thanks guys!

Quick question I noticed that the top line on the DMD is out.

Any way of fixing that? Or is it a bad DMD?

Not sure if only the top line would mean a bad connection or something.

The rest of the DMD is nice and bright
