I picked up a 70 inch 650u from bbuy over the weekend. Initial impressions were great. Snappiest TV I have owned with good Netflix integration. Excellent picture with solid blacks, despite a few cloudy patches in very dark scenes that I can live with.
However, tonight I noticed a thin band at the very bottom of the screen that was most obvious in bright lit scenes (e.g. snow) with a lot of motion (e.g. snow boarding) that looks slightly lighter and sometimes but not always blurred or distorted. Has anyone encountered this?
I saw some guy's review on amazon that warned about issues at the bottom edge of the screen. When I look up close at the screen I can't see any obvious defect, so wonder if this might be a processing issue? The material I was viewing was Netflix HD and a regular DVD. I will put on a bluray tomorrow and see if that makes any difference.
I have the same clouding issue as you but haven't noticed the thin band at the bottom. The clouding issue is only perceivable for me when watching dark scenes with all the lights off at night. I have never seen this much clouding in a tv. Seems to be normal for this model from what I can gather.
