I just bought a 57732 from my parents as they upgraded to the 65737. They bought the 57732 from Fry's in 2007 with the 5yr extended warranty. About a year ago they used the 1 time bulb replacement. Ever since then the screen had a cloudy, washed out look to it. It seems as though the whites and light colors bleed into the blacks/darker colors. It had always bugged me, but they just went along with it, saying that's how it had always looked. Now that I have ownership, I was considering cleaning the lens as has been instructed. My question, is this something that would be covered under the warranty? I read the warranty terms and couldn't come to a conclusion whether or not it was included. Also, if I were to do this, would it void the warranty?
