-How old is the unit?
- Do you have this problem while watching all different devices hooked to this television? (DVD player, cable, satellite, game counsel, ect.)
Please give me this information and I will be happy to assist you further.
Did you try the screen mode button?
Well the button on the remote that says Screen Mode should change something with the picture, are you sure you tried it?
I am sorry, I misread what you wrote, I thought it said you could not find a button on the remote to control it....not that you cannot find the remote. I think that is a major issue, you cannot change that setting without that remote.
