My local channels disappeared and I've tried every workaround here, plugging in my TV antenna where the cable TV would normally plug in, and could get nothing but five channels, NONE of which were ABC, CBS, NBC, FOX, or even PBS. One channel was the local city's "calendar" and the other four were duplicates of local weather in four different cities.
I've used only Roku TVs in the past and had just purchased a 58" Hisense Roku TV last week. I'm likely going to return it because nothing is working as it should. Even when it says to hit the * button for more information, the remote simply makes a dull beep and does nothing whatsoever. I've even tried using my old Roku remote, which at "least" had a microphone button where I could say "Turn to channel whatever."
What happened in September with the Roku update that destroyed all settings? My local channels all worked FINE until this recent update. So many wasted hours, and hours, and days.
