at those prices.....its most likely more than a few years old.
you would have to see if you can find repair parts for your model online. if its just a "screen protector" that is broken you might be able to fix it yourself. if its the actual screen thats cracked....it might not be worthwhile as it could easily cost you $700-1000+ and you can get a new tv for around that or a little more. you might be able to get a free estimate from a tv repair shop.
No, we just bought it last year. I really would like to get it fixed! Or is there a store that would buy it and sue the parts? I just hate that I can't get anything for it. It was brand new and we never used it - the crack in the screen is hairline and barely noticeable to the naked eye.
