Have TV Questions? Ask a TV Technician
Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble, Dan.
The tv and the roku are 2 entirely separate systems. The roku does not have any affiliation with the antenna at all.
You need to use the SAMSUNG tv remote, put the input mode to TV (not to hdmi, component, etc).
Then, you can go into the samsung setup menu, with the tv remote (not the roku remote) under Channels, then run the auto scan.
