A year ago I bought a TV (same as you: directly from Amazon). It came with the screen cracked. I asked for a new one... The replacement came cracked. On the reviews, I saw a couple people mentioning that the screen came cracked. They wanted me to send them back by Canada Post, but I said no way I would do that, as I don't drive, and I would not carry 2 55" TVs on the streets. They ended up paying for purolator to pick them up at my place.

I asked for a refund and bought on Best Buy. No problems!
