I bought a Sony Kdl-60w855b TV and after I set it up I noticed down the sides and the corners there's dark shadows when the screen has light colours on it. I sent it back and got a replacement sent out but the new one has the exact same issue. I'm wondering if it's built that way or it's a faulty batch. When watching TV or playing a game it is less noticeable but still there on light scenes. Is it worth sending back for another screen or just get my money back and get a different make?
