I'm sorry to hear that you're having this issue.

If you haven't already, register your unit here:


Doing so may qualify you for an additional 3 months of warranty. After you've done that, call 800-SAMSUNG and request a service call. Be sure to mention that you registered online and would like to use the additional 3 months afforded by the website.

If that doesn't help, ask for a transaction number and post it here.
