I was wondering if anyone could advise... My tv is only 1 month old and in the top left hand corner it has developed a green tinge when on a white background. It looks like a magnet has been placed on it. Now I live by myself and I know for sure that nothing has been put ontop of the tv, nothing. What can I do about this tinge? I mean it's only small, but I can see it if I look for it, it's definately there and I don't think it should be on a £2K tv set. Do I live with it, or will Sony sort it out for me under warranty? Any suggestiosn much appreciated! thanks, matt.
