Yup. Mine crapped out on me in the 800-1200 group. It had about 900 hours on it and then it wouldn't fire up.
And just to rain on other people's parade, I too did the "leave it on until bed time" routine, and look how far it got me! I wasn't an every day watcher either. When I am going to watch something, I turn it on when I get home from work, watch some TV/Movies and go to bed. It's usually on for about 5 hours on evenings like this. It's on all day Sunday for football (through evening game too!) and on for several hours on Saturdays (if I'm home).
