I just bought this sony and there 350 BD player, but I noticed when playing Underworld that in the dark scenes that almost 40% center of the screen has a clouding effect but disappears in lighted scenes. I dont think serial numbers match in Canada to my brothers across the sea but this is one of the flagship models. Is there a upgrade fix and if so how do you upgrade? What is the deal with this LCD. Just one more thing if anyone has a sony like this there is a picture, backlight, black level that were set on 100% of course, where do you set yours? Thanks Mike
