It should be noted that CRT burn in is not covered by any manufacturers warranty. It is not covered because it is caused by pushing the projector beyond its recommended range of use. You are free to run a projector too hard, but its not free to fix it afterward. If you want a brighter image, get a brighter projector and a blacker room and a brighter screen. Don't run your projector too hard and you won't have to worry about wrecking it. You will know, without a doublt if you are running it too hard. Use Avia or VE and check out the blooming boxes. If you have ANY blooming, you are running it too hard. If you can't get a bright enough image without blooming, you should change other, cheaper things to achieve a brighter image(black room, bright screen, smaller screen, brighter projector). Just my 2 cents(with the exchange, I owe you money!).
