We've discussed your first problem. As I mentioned, I sent my first projector back for that problem and they replaced it.
The third problem could well be a stuck mirror, and I wonder if the second problem is related. I know of one person who sent their projector back for stuck mirrors and they replaced the chip. I would guess that replacing the chip might also stop the first problem, which is noise generated by the XPR system.
That is certainly my hope!!
