I have a 4 week old Viera and already have a dead pixel near the centre of the screen. Is there anything that can be done about this? Am i covered by warranty or could i claim on house insurance as accidental damage or anything? The pixel was alive for about a week then just never came back. I read a previous post saying that they can come back to life, but its now been 3 weeks since i first noticed it. Any thoughts/ideas welcome..
