How do I watch antenna channels on an older Samsung TV that also has a Roku?
Answer
Switch the Samsung TV input from the Roku HDMI input to TV/Antenna, set the tuner to Air, then run Auto Program to scan local stations.
Before you start: stop right away if…
- Do not pay for “channel unlock” services to receive free over-the-air stations.
Follow these steps
Switch the TV input away from Roku
Press the TV remote’s Source/Input (or AV) button and choose TV, Antenna, or the coax tuner input—not the HDMI input used by Roku. On a universal remote, press the TV device button first.
You should see: The screen leaves the Roku interface and shows the TV tuner.
Set the tuner to Air/Antenna
Open Channel or Broadcasting settings and select Air or Antenna, not Cable.
You should see: The TV is set to scan over-the-air signals.
Run Auto Program
Choose Auto Program, Auto Store, or Auto Tune and let the scan finish completely.
You should see: Local stations such as ABC, CBS, and NBC appear in the channel list.
Tune a local channel
Use the channel up/down or guide on the TV tuner input to open a scanned station.
You should see: Broadcast TV plays with picture and sound.
Return to Roku when desired
Press Source/Input again and select the HDMI input for the Roku whenever you want streaming apps instead of antenna TV.
You should see: You can switch freely between antenna TV and Roku.

Extra tips
What to look for: A Source/Input option showing HDMI (Roku) versus TV/Antenna, and an Auto Program or Auto Store setting set to Air
Before you change anything: Confirm the antenna coax is connected to the TV’s ANT IN, not only to the Roku. Have the Samsung or universal remote ready. Note any Weak or No Signal message after switching inputs.
