My TV developed the same issue that over 2000 people have reported. The TV switches on and off on its own. CBS also did an investigation. Samsung did offer free repairs for this issue till 2013. I advised them I did not receive any notice. They no longer cover it, gave me a repair order# and that I would have to pay if I cared to have the repair. Needless to say they do not stand by their product, and I will never purchase a Samsung product.
