I bought a used spare DMD about 3 years ago that was supposed to be outgassing but looking fine. Never tested it. I just tested now finally and it has about 15 lines vertical lines out. I figured it was shot and junk...
So, I decided to push from the backside towards the glass side squeezing it with my fingers and the lines all fill in. When I let go, then the lines go out again. The color looks great on the lines that are there. Any thoughts?
Is there a way to tighten or adjust them? Is it need of a solder reflowing?
I've never messed with one but it seems like its not shot, just in need of some minor repair.
