Given all the transportation it took to get your set to you, anything is possible. Be sure to call the seller as well. My advice is to return it.
Today I bought a Samsung LED TV (Model number: UE46EH5305). When I installed it at home and turned it on, I saw a collection of blue pixels right in the middle the screen. Initially I thought it was some sort of a graphic, but then I saw it in all videos from all possible sources. When the screen is black they appear blue. If the screen is white, they appear yellow. Its quite annoying to see such a problem with a brand new TV. What could be wrong? I have written to Samsung customer care and also to the dealer. But since this is weekend I wont get any response until Monday morning. So I had to post this here to see if someone has any thoughts about this.
Hope the dealer replaces the TV.
