My TCL Roku TV is doing the same thing, only with the Roku Channel. I’ve had it for almost 3 years. My remote control wasn’t working, so I changed the batteries and it works now. My TV is no longer responding to it. It keeps making that “magic wand” type noise, as if you were to switch channels by pressing the ESPN button on the remote (for example), but it just stays on the Roku Channel and nothing happens. The light underneath the logo that lights up when you turn the TV on is flickering. This has never happened before. I unplugged the TV and it’s still doing it. I don’t know where the reset button is. What is going on here?
