This is a photo (attached) of the top right corner of my 32" Sharp Aquos GA5U. Has anyone ever seen anything like this? It just showed up a couple of weeks ago. I've had the TV for about 3 years and have never seen any weird artifacts like this. It looks like a smudge, but it is definitely NOT on the external surface of the LCD. Could there be some kind of mold on the inside of the LCD?!Would it be possible to open it up and clean it off?
