It might be called Live TV (on LG TVs) or Broadcast (on Samsung sets). You may see the Channel Scan control right away, or it could be one layer down, under Antenna, Channels, or Channel List. 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. The process varies a bit depending on which brand of TV you own, but ultimately you’re looking for a control that says Channel Scan or Channel Tuning. It’s fairly simple to rescan for channels.
