Roku Premiere, switched from HDMI to TV and can't switch back again
Hello, everyone. I installed Roku Premiere yesterday and it was working (Samsung TV with antenna, no cable hook-up), but after switching the Source to TV, I wasn’t able to switch back to HDMI later on. So… disconnected/unplugged, waited, reconnected/replugged, but no luck after several tries. I'm repeatedly getting the same prompt: "This source is not connected. Please check connection again." Can anyone help? Thanks so much.
