I'm having this weird problem where I can't watch any antenna channels. If I click on the "Live TV" option from the home screen, I just get a black screen on all my channels. Sometimes it shows which show should be playing, sometimes it shows "no signal." But if I go back to the Roku home screen and just navigate the selector over the "Live TV" option without selecting it, I can see that the channel is working fine. I can literally watch any antenna TV channel in that tiny little box on the home screen, but as soon as I select "Live TV" to watch it normally, it goes straight to a black screen with no audio.
Any idea what is causing this issue and how I can fix it?
