Question about Mitsubishi WS-55908 55" Rear Projection Television
If you have a gray band left and right on the screen--in the background----It is a burn on ALL THREE OF THE PICTURE TUBES THIS SET USES.
What happens here is if Contrast (picture) is set all the way up and the set used in the 4X3 mode---it will burn a permanent mark into all three tubes.
If this is the case you may just want to live with it as all three tubes would have to be replaced--over 800 dollars parts and labor depending on where purchased.
I saw a lot of these with this problem when they were fairly new---the DEFAULT setting on these sets is contrast all the way up and this is what burns the image of the 4X3 into the tubes.
Let me know if you have questions. I know this is not good news, but based on your description I think it is what has happened.
