I'm sorry to hear that you're having this issue. I think I'll be able to help here.
I'd recommend immediately registering your product online here:
(in the middle of the screen)
In most cases, this will extend the warranty for an additional three months on top of your warranty. Then call 800-SAMSUNG, note that you've registered, and would like to have your set inspected by a technician.
Does that help?
