I have an Epson 5030UB, it is going on for about a year now. Over the past month I have experienced the Projector shutting down after about 5 hours of viewing. I had a company come in and clean it(no issues). I get no flashing light indicating that it is overheating, and once it shuts down I can power back on right away with no issues. I do have a Ultimate Harmony Remote, I noticed this time after I had the receiver on "mute" for a long time everything shut down. Anyone have any thoughts?
