Can any of the forum experts help me out. I noticed a picture fault on my Hitachi 42pd3000 some time ago, a light grey blob on the screen when displaying a black or dark image in low ambient light. To cut a long story short it has finally gone off to the service agent who say that this problem is inherent in this screen (plasmas are new technology after all) and that it is caused by the plasma gas charging. As a result it would seem they are not going to do anything about it. This sounds like a bag of arse to me and I just wondered if there was anything anyone could suggest that I could use to counter their argument. All contributions gratefully received.
