I have a ~13 year old 58" Samsung plasma, model PN58A550S1FXZA, that recently started showing a bluish rectangle in the upper right hand corner of the screen. It's about 3" wide and extends from the top of the screen halfway down. See the picture below.

The blue rectangle appears on all inputs. The TV otherwise seems to work just fine. Is this a panel issue or something fixable?
