How to fix the issue?

If the auto scan is unable to find any channels on your TV then below we have explained a few ways to help you fix the issue.

Redo the scan properly

Consider redoing the scan if your initial auto-scan doesn’t yield the desired results. Sometimes, a second scan can pick up missed channels during the first attempt.

Check the TV input

This method is effective when the antenna is connected directly to your TV. However, if the antenna is connected to a set-top box, then follow the other below-explained troubleshooting methods.

Usually, when you connect an antenna to your TV, you need to change the input or source setting from its current setting to either the TV or Antenna. The name of this setting might vary depending on the brand of your TV.

To do this, find the Input or Source button on your remote control and press it. It will show you a list of available input channels on your TV. Now, select the input option that says TV or Antenna. Once you’ve changed the input setting, try rerunning the auto-scan to check if the issue has been resolved.

Check the cable connection

Faulty or loose cable connections between your television, antenna, and other equipment can disrupt the signal flow and prevent your auto scan from finding channels. Double-check all cable connections, ensuring they are securely plugged in. Replace any damaged or worn-out cables to ensure a strong signal connection.

Change the antenna or dish position

One of the primary reasons your auto scan might not be finding channels is the placement of your antenna. Antennas need to be positioned correctly to receive a strong and clear signal. If your antenna is obstructed by nearby buildings, trees, or other obstacles, it can lead to signal interference, resulting in a failed auto scan.

Ensure your antenna is placed in a location with a clear line of sight to the broadcast towers. Experiment with different antenna positions to find the optimal spot for signal reception.

Check the weather condition

Extreme weather conditions like heavy rain or snow can temporarily disrupt signal reception and prevent your auto scan from finding channels. Wait for the weather to improve, as these issues are usually temporary. In the meantime, consider streaming services or other sources of entertainment.

Power cycle the TV

There may be some minor bugs or glitches in your TV that can be resolved by power cycling or, in simple words, restarting your TV. To power cycle your TV follow the steps below.

  • Turn off your TV and unplug the power cord.
  • Wait for about five minutes.
  • Plug back in the power cord.
  • Rerun the auto scan and check whether it works.

Contact a technician

If none of the above solutions seem to work or if you are not comfortable with troubleshooting technical issues, it may be advisable to seek the assistance of a professional TV technician or a qualified installer. They can diagnose and address the problem more effectively and ensure your TV channels are correctly configured.
