Hello, I just recently purchased a Sony 34XBR960 wide screen. After setting up the T.V. I noticed that there are 3 black horizontial lines through the screen. One towards the top, one through the middle, and one towards the bottom. The black lines are always in the same place and are about the size of a hair. Are these part of the design or on just my television? I was not sure on this. Thanks all, Jon.
