I have had this TV for about 3 months now and last night I'm watching a movie where it's a bright scene. Well wouldn't you know it, the top left corner of the screen has a slight green discoloration. MAGNETS!!! Was my first thought, but my speakers (front left,right and center) are video shielded. Plus my left and right are approx 1 1/2 feet away from the T.V. Center channel not even close. So could it be the speakers within the T.V. that are causing this? I have a freind who has the 40 XBR 800 and his after 1 year as the same problem, only the botten left corner. Has anyone heard of these models having issues like this? I've called Tweeter and told them, they are supposed to get back to me but haven't yet. God I hope I don't get the run around on a T.V. this new.
