First thing I'd guess when seeing this is issues with the DMD controller. Reseating the connectors is a good idea, concentrating on everything attached to the DMD controller. That's the board at the other end of the cable that goes to the display itself, right of center board in the top row in the backbox. There's a couple of ribbon cables connected to it - reseat all the connectors on those, and also all other connectors plugged into the DMD controller board (the large connectors near the bottom of the board).
