Just had a Sony KD 28DX51U delivered and installed. As it was being installed I commented that I could see the digital banners at the top left of the screen sloped off. The installer (really a term for someone who unpacks the TV and puts the stand together) agreed but said there was nothing he could do! I immediately got onto Empire Directs service department who said they would call me back. Not heard anything yet! My wife also aggress that the screen picture is distorted in the top left hand corner, e.g. the Sky News banner slopes down to the left hand side. This is happening on both the TVs digital tuner and via Sky. I makes me think there may be a problem with the tube. Can anyone out there provide any help??
