I know you said that you did not want to buy a new TV. But If you have to I just wanted to give some helpful advice. I would not get a projection screen again. My grandma just bought a new one 2 years ago and had to replace the bulb in hers twice at $400.00 a bulb. She just got tried of haveing to replace the bulb. She said that if she'd knew that this was a potental problem she wouldn't not have bought one. And the Tv's was just passed the warrenty. She said that she would never buy another one. So hopefully this is helpful to some point.
