I don't have this tv in hand now and also don't have the make and model of this display at the moment but all I am looking for is general information for now.
This tv has a smudged / blurry area on the screen. It looks almost like it is dirty from a oily hand but it doesn't wipe off. It is not a rectangular area.
I am not familar with the common failure modes of Plasma displays. What is your best guess would cause this.
Thanks in advance,
Mike
