Hi guys/gals, my parents TV has developed a weird kind of almost water mark on the screen. I have never seen something like this before on a LCD TV. It appeared a couple of month ago out of no where in the bottom left side of the screen. It is there regardless of what video sources are used. they have cleaned it since and the mark remains. Below is some pics with it outlined so you know where to look on the untouched pics.
Any ideas of what this is?
Any ideas of what this is? What sucks is that the warranty ran out last month.
