I set up my new LC-70LE632U yesterday. After initial setup, I immediately noticed clouding in 3 of the 4 corners along with some minor issues are the edges. 2 of the corners are quite noticeable during dark scenes (even my wife noticed!). I am setting up an exchange with Sears. I know minor clouding is almost to be expected but this set seems to have excessive issue. Hopefully the new set will not be as bad.
Otherwise, I am very happy with the PQ.
