I have or should I say had a HD70. It was doing the color wheel changing issue. So the wife said try blowing it out. Well with out thinking I did and the pj was on. I blew it out all around it then on the side with the lens I received a blow of fire like something blew on the inside. Any advice here? I have this torn apart but I am not sure where to look to see what is blown. I tried a new bulb and the unit fires up but nothing happens. The fans run, but no picture. HELP someone who listened to his wife and did not ask or think first. Yes, I admit that was a STUPID move on my part!! No really we are at a loss here.
