Summary: The warranty on the TV expired on 11/17/2012 - one year after purchase. Yesterday the TV decided to start shutting itself of and turning itself on randomly. Also, after being on for more than 30 seconds it stops responding to any commands - no volume, no menu, nothing. Doesn't matter if you use the remote or the controls on the set. I downloaded firmware to a USB, but when it attempts to install there is an error message and then the TV turns itself off again.
