I have a Samsung 82" 82RU8000WXXY recently bought (2 weeks ago). Noticed the same problem where the TV randomly turns on a few seconds after turning off. It doesn't happen everytime but does happen every now and then. It's so new that I don't have anything connected to it (no HDMI connections, Soundbar, No Antenna, Nothing). It's only got Wifi connected and we have only used streaming apps (Netflix, Amazon) It's obviously still in warranty and I also purchased extended warranty. I am worried and thinking what to do.... Obviously spent alot of money for the big screen and went with a big named brand so I don't have to face these crappy issues... Wasn't prepared for this.
