Head to Samsung.com and register your set.
http://www.samsung.com/us/support/owners/product/UN65ES8000FXZA and clicking on Support I read
"Register Your Product

Do that then call it in.
The TV is 1 year and 2 weeks old. The picture is constantly being replaced with weird (but kinda cool) geometric patterns and then I have a hard time turning the TV off. It happens at random or whenever I try to adjust the volume. The audio goes away at the same time.
