The process is pretty simple but varies a bit depending on what brand of TV you own. Start by using your TV remote control (or a digital converter box remote if you still have an older analog TV) to press the Menu or Setup button. You may see the Channel Scan control right away, or it could be one layer down, under Antenna, Channels, or Channel List. It might be called “Live TV” (for LG TVs) or “Broadcast” (for Samsung sets).
If you don’t see any of those options as soon as you press the Menu button—and that’s not unusual—you’ll have to go one layer deeper by first choosing Settings or Setup.
Once you find Channel Scan or Channel Tuning, you may have a choice to tune automatically (Autotune or Autoscan) or manually. You want the automatic option, which will make the TV search through all the channels.
If you don’t see any of these options, you can usually perform a channel scan by selecting the Input button on the TV remote or in the TV’s main menu, then choosing Antenna.
Depending on the number of channels you can receive, it could take a few minutes to complete the rescan. If it doesn’t work the first time, try again. We recommend doing a second channel scan anyway just to see whether you get any stations you missed on the first rescan.
If you’re already using an antenna to get free TV, you’ll probably only need to rescan your TV—you won’t need any new equipment.
The one exception is if a local station moves from UHF (channels 14-51) to VHF (channels 1-13) and your current antenna is either UHF-only or gets poor VHF reception. In those cases, you might want to consider a new antenna.
