I had a similar situation happen with my Lethal Weapon 3. It was working fine, then I had someone come over to look at buying it and when I turned it on, that same thing with the DMD, "Back in Action," general illumination happened. Perfect timing, right? I ended up selling it anyways and found out from the buyer that the fix was a new power supply board. (I actually think he sent the original off and had it worked on.) Hope that helps!
