As I have mentioned before, I have a KDL-40V2500 with a significant cloudy backlight problem. I went to BestBuy today to exchange for a set without the problem. So after opening three other sets, and hooking them up, the problem was on all three sets as well (to varying degrees, but nowhere near satisfactory since I could easily see it in the brightly lit BB home theater area and they were all manufactured Oct 2006). Two of the three also had stuck pixels which really makes me wonder. I am definitely going to have to follow up on this with Sony as I can not expect Best Buy to open and repackage every set in stock until I find one.
