As our office deals with many things, the answer is simply yes. No maker can escape the bath tub curve.
I have a Samsung 32' F6100 series 3D LED TV.
Suddenly dark shade appears in the below half of the screen, is more visible if any lighter color appears in the screen.
MyTV is still under warranty, but just wondered if anyone else had had this problem and what it could be. Our TV is only a few months old.
