I have an Optoma TX1080 that I purchased approx a yr and a half ago. I am on my second bulb which has about 1200 hrs on it. This projector is ceiling-mounted and sees heavy use as the main TV in the house, at times for up to 8 hrs a day. For the first six months or so that I had it I was very pleased with it. Then it started developing color issues, banding in areas that were darker or lighter, the highlights looked "blown out" and the situation got progressively worse until I sent it back to Optoma for repair. When I received the unit back it had been restored to its former glory. Now, however, after about five months it has begun to show the same symptoms which have fairly rapidly gotten progressively worse to the point where it is almost unwatchable. What's going on with this unit? I am concerned that it just can't stand up to regular use even though it was marketed as both a business and a multimedia entertainment projector. I have noticed that it tends to get worse the longer the unit is on so I thought it might have been heat related but I checked and cleaned the vents to the unit and it didn't make a noticable difference in either its performance or the length of time it took the piture to degrade from bad to very bad. Thanks in advance for any insight you can give.
