Working on my DESW project which came with a non working DMD. I've plugged it into another pin with DMD and got the display to work. What should be my next step in locating the display issue with my Data East pin?

Yup already checked all the ribbon cables. I do have the manual.
When I restored a DESW, I did this upgrade with the latest DMD chips from MArco.
I can't seem to find the part from marcospec.com. What's the item#? I already have an order build up at that site. I'll just add it my preexisting order.
Check the voltages at the display board: -110, -98, 68, 12 and 5 volts (or within 10% of those values).
It must be a power supply issue because the I got the following:
-116 , -101, 0, 0, 5
Unfortunately it was at the DMD.
