Hi, I am curious what you ended up deciding to do about your TV. I recently purchased a lc-60le640u and it has the EXACT same light bleeding and clouding pattern as your second one. It has the exact same flower/cross in the same space and the light bleeding seems to be coming from the same corners. Prior to purchasing this TV I had bought a lc-60le600u which had a clouding pattern similar to your first. I ended up returning that one because I was able to find the 640 for the same price. So now I am trying to decide whether or not to exchange my TV (also BB) and try to get one without the clouding. Is this typical of all of the 640s or did I just get a bad one? If they are all like this then I guess I can live with it. As a side note, the clouding is only noticeable on mostly black screen. It is not noticeable if there is any picture on the screen over the clouded areas. Also, my back light is on "STD" and of course the effect gets worse if I brighten it up.
