ROKU TV freezing, turning off, and not turning back on
I bought a ROKU TV from Best Buy two years ago, it was brand new, still in the box, but about 6 months or so into having the TV, the screen would freeze, pop to a screensaver, and then shut down and reboot. It would happen about every 30 minutes to an hour that the tv was on. However, now it is shutting down, popping, freezing, and will not turn back on. What could be the issue and how can I get it fixed? Has anyone had this issue before? Can you tell me how much it might cost to fix? Like I said, it was brand new when I bought it.
