I bought a TCL 55in 4K Roku TV about 3 months ago, and today while I was watching Netflix, it made a loud popping sound (like a breaker flipping) and then there was no power. I thought maybe my surge protector had flipped, but upon checking it everything was fine. I have tried unplugging the TV and plugging it back in, different power cords, even power cycling and nothing happens. Any idea what's going on or how I can fix it?
