The dumbest things seem to happen to me lately. I just got done moving my Ghostbusters down to the basement, and that involves removing the back box from the cab. So I took pictures of everything, as I usually do... And put it back together again after the move. Now the DMD will not power up again. The rest of the machine works fine. I reseated the display cable a couple of times, and I have 5v at the power plug for the DMD. Am I missing anything else?
