Any advice on how to fix my dmd issue? It is only showing a portion of the dots. I have tried reseating all the connectors and a different DMD display but no change. What should I check or test on the board? Thanks for the assistance

Did you reseat ribbon cables, oth ends, from CPU to DMD driver board to DAM ?

If so, then I'd check power to each pin on the big connector on the DMD.

Rebuild the voltage section on DMD power board and all will be fine.Replace all elements with no exception.
But first check/measure the zener diodes and the big white resistors.And usually the resistors in time begin to have cold solders.If diodes and resistors are fine then replace everything.

Of course if you have spare DMD board you can check with it too.
