Right in the middle of the tv, there is a yellow blob when i look at it from an angle. its not very bright but i can see the yellowness (especially when the tv is off). how can i fix this? thanks
When the tv is off? I believe you are talking about the anti-glare coating on the screen. It's a combination of factors which are all normal. The light from the room is passing through the screen as well as reflecting off it. I believe this is what you are talking about although on my Grand Wega and all that I have seen it is a white splotch that actually moves as you walk past the screen (when its off).
it shows when the tv is off and is noticable when the tv is on and the screen is all black...its not the entire screen that is yellow, its a certain section of it and it does not move when i look at it from different angles.
