Panasonic Plasma has developed a thin blue/purple line in middle of screen??
My 4 year old 42 inch Plasma (think it's the LX80 or something) seems to have overnight developed a very thin, bright blue ish purple line down the middle of the screen (it becomes a black line when changing between channels on the blue background)
Has anyone else experienced this and what can be done? Surely a 4 year old set isn't for the scrap heap already??
