Ok I have a Hitachi Ultravision 65" and I love it. So today my wife is cleaning the screen as stated in the manual with a damp soft cotton towel and after she cleans it there is this UNGODLY blotch in the bottom right hand corner of the screen. It looks as if I had two screens and some ink got inbetween the screens and smeared up. Any ideas of what this is? Could it be water on the inside of the screen from the damp cloth? Will it go away, am I screwed and if I am screwed how screwed am I (how much money am I srewed ou of to fix.)
