Why not return it if it isn't OK?
The sales person in the shop will surely be able to show you comparable TV's, so you can see if it happens in just yours (then it's defective), or in all TV's of this model (then buy another model), or in all TV's of this maker (then buy from another maker) or (but I don't hope that) that it's the same in all TV's.
Hi guys , a couple days ago i bought a samsung 46 es7000 . At first i was really happy with it untill i saw some dark screens and it revealed some cloudy patches . And i cant decide if its bad enough to return it , and when i do i might get a set which is worse . I still see this with backlit turned down please give me some help and advice , pictures in my picasa. https://picasaweb.google.com/117822582738577235304/December12012?authuser=0&authkey=Gv1sRgCNe4mYqC9IyazAE&feat=directlink
