I have a Sharp Roku TV. I also am not getting any channels to show up. I have reset the tv, bought a new HD, long-distance, amplified antenna, moved the antenna, essentially everything I’ve tried has not worked.
It's likely a software issue. If you read above, most people have had this issue since updating their tvs.. I'd like to add another thing. I used a Tabloo to get locals and it worked through another input.
