So I tried to hang my Sharp 733u to my TV stand (its a mount and a stand). When I got it all together I noticed a big green looking cloud in the middle of the screen. I immediately took the TV off the mount and the spot was still there. I didn't over tighten the bracket or anything. I rubbed the spot very gently and it went away. Does anyone know what this could of been and should I try to hang it again? I dont want to risk damaging it.
My 70" 632U had some green clouding in the middle of the screen on dark or black scenes. What I did was turn the TV off, then wipe the entire screen inside to out with a microfiber cloth applying very light pressure, similar to what you did. The green clouding completely disappeared. I got the idea from someone here on the forum with a similar problem. Mine has been fine ever since. So if it went away I wouldn't worry about it.
