Just got this TV from Best Buy a few months ago. I get random shutoffs while watching 4k Netflix shows. I have updated to latest 8.2 and am connected via ethernet, so loss of connection isnt a problem. I stream at 15Mpbs while in 4k. It also happens while using Youtube.
I just bought a TCL 55r615 yesterday from Best Buy. The TV has been on all day, l ike most TVs on the weekend. I connected my PS4 Slim to it. Current'y it's downloading Spider-Man. Since doing this I've been experiencing my TV randomly shutting off. This happened while watching on the YouTube and Netflix App. Any and all help will be appreciated.
