Try to get a warranty with the TV (not the factory warranty) one from where ever you buy the TV from.
I bought a 50 in. flat screen last yr. from circuit city here in the US and I opted to pass on the warranty from the store...big mistake.
I was playing my xbox quite a bit and left it on over night and now it has an image of Ghost Recon burned into the damn thing. It not bad but you can notice it when the TV goes dark. I called the factory and they don't even want to fuck with it and i doubt ill get it replaced.
I just got this
TV, I highly recommend it
