  1. Remove every obstacle or clutter near your TV and antenna.
  2. Check your antenna connection to see if it’s properly connected.
  3. Connect the TV with a signal amplifier.
  4. Run a channel scan as this may resolve the issue.
  5. Use a rotor or an attenuator with the television.

If none of the above tasks work, you can call your cable operator and let them fix the issue.
