Preparing Your LG TV for Channel Scan
Good preparation makes the scan process smoother and reduces the need to repeat it. Follow these steps before you start.
Check Connections and Signal Source
For over-the-air scanning, attach your antenna firmly to the RF input and choose the correct input source. If you are using cable, verify that the cable outlet is active and the coaxial cable is securely screwed in.
Set the Correct Input and TV Mode
Switch the TV to the appropriate TV or Antenna mode, not an HDMI or streaming source. This ensures the tuner circuitry can process the broadcast or cable signal properly during the scan.
Using the Auto Program Feature
The Auto Program function is the fastest way to scan for channels on LG TV when you want to discover available stations automatically.
Accessing the Auto Program Menu
Open the Home screen, go to Settings, then select TV or Broadcast, and choose Auto Program or Channel Scan to begin the process.
Choosing Scan Type and Tuning Method
Pick between Air (antenna) and Cable, then decide whether to include only strong channels or all available channels. Confirm your choice to let the TV search and lock in frequencies.
Managing Scanned Channels
After the scan finishes, you can organize, hide, or reorder channels to match your viewing habits.
Editing the Channel List
Use the Channel List or Favorites menu to rename channels, create groups, move favorites, or hide stations you never watch. Saving these settings keeps your browsing quick and intuitive.
Performing a Quick Re-scan
If new stations appear or your area adds channels, run another scan and choose the option to add channels without deleting your current list. This updates your lineup without starting from scratch.
Troubleshooting Common Scan Issues
When channels are missing or the scan fails, specific checks usually reveal the cause.
Weak or Missing Antenna Signal
Reposition the antenna, check cable connections, and rescan. If problems continue, verify local broadcast tower locations and consider a stronger or amplified antenna for better reception.
Cable Service and Provider Settings
For cable scanning, ensure the line is active, splitters are working, and any required CableCARD or security settings are applied. Contact your provider if channels are still not appearing after a fresh scan.

FAQ
Reader questions
Why does my LG TV find fewer channels than before after scanning?
This usually happens when the antenna position changed, a broadcast tower was removed, or the scan excluded higher-numbered channels. Repeat the scan and include all channels to restore the full lineup.
Can I scan for channels while using a satellite receiver with my LG TV?
Yes, but you typically treat the satellite receiver as an external source. Set the TV to the correct HDMI input, then follow the receiver on-screen menu to tune channels instead of relying on the TV antenna tuner.
How often should I scan for channels on my LG TV? Scan once after initial setup, again if you move to a new location, and another scan whenever you notice missing channels or after severe weather that might affect antenna signals. What should I do if the channel list keeps resetting after I power off the TV?
Update the TV firmware to the latest version, use the backup/restore feature if available, and avoid factory resets unless necessary. If the problem persists, contact LG support for advanced diagnostics.
