Would anyone be able to advise on John Lewiss course of action when it came to having a fault with a plasma? When I say fault, I mean the purple snakes thingy. Its not happening all the time, but is becoming more frequent and slightly annoying. I love the TV and apart from this, I am more than happy. Just wondered if in this situation whether they could repair it at home or if I needed to get it picked up etc for repair. Anyone had a similar problem and had it resolved by JL?
