I've read people talking about it, but no stories yet.
What I plan to do is get ready to buy a new dmd chip during some video watching downtime next week and before I pull the trigger try to fix the current one.
My two options are currently compressed n2o (I've read that the co2 in air duster was bad for some reason), or using a cmos sensor cleaning kit for a high end video camera.
The thing is, are these mirrors really "stuck" or are they actually burned out?
After doing some research, my educated guess combined with experience tells me that it's more likely the electromagnetic filaments on one side of the dmd mirror is burned out rather than the mirror being physically stuck. It seems that heat, which is the root of all other problems in an aging projector, has probably caused these to go over spec and get stuck in a particular position because the actual mirror is no longer physically capable of turning off -- rather than just being stuck in the on position via a piece of dust.
Does anyone have experience with this before I dig in? It should be some interesting research.
Sadly, in my current location, I don't have access to a SEM, or I would just take some pictures of the mirrors to see what's up at the micron level.
