I purchased the above just over 4 weeks ago. I have noticed that on watching football, motor racing, golf or at times films there are a few faint vertical lines running down the screen especially when the camera pans. This makes watching the tv unbearable. I am disappointed as this is supposedly their flagship model. I read the reviews on what hifi and there was no mention of this. Is this normal? An engineer is calling . I hope he does not say this is part of the course. I hope Sony customer service is good as the set is only about four weeks old.Could an engineer tweak the problem out? Is this a common problem?
