Since it's new, I'd place the call to Samsung service and let them do their thing.

I just recently bought a demo UN65HU8550 from a small mom and pop shop and just a couple days later I started experiencing random reboots. When I went to the "Contact Samsung" to get information on my unit, it showed Model: UN60HU8550 with a different Serial than what was on the back of the unit. The back shows it as what it physically is, UN65HU8550.
Did they have this serviced before or did their own repair? Or is it possible to have those two different boards in this TV? Is having that board in the TV obviously the culprit?
