I never noticed it until I was up close looking at the panel for any unusual screen issues. It's not noticable at all until you're looking for it. Just curious if anybody else has the same spots in the corners.
I haven't looked/noticed any on my set and I have never heard about anyone else having this phenomen so I would not call it normal.I've noticed in the 4 corners of my 64" F8500..there are small bubbles in each corner. They are limited to the blank border strip and not onto the screen. Assuming it's just the filter reacting from the heat of the tv. I have about 2000 hours on the set. Is this normal?
