The Basic Channel Scan Process

To scan for channels on a Samsung TV, go to the home screen, open Settings, select Broadcasting, then choose Auto Tuning (or Channel Scan on some models). The TV will search for all available channels in your area and add them to your channel list. The scan usually takes 5 to 15 minutes depending on how many channels are available where you live.

The exact menu names vary slightly between Samsung TV models and years, but the path is always Settings → Broadcasting → Auto Tuning. Once you start the scan, you do not need to do anything—just let the TV run through the process. When it finishes, your channel list will be updated with whatever signals the TV can receive.

Key Takeaways

  • Channel scanning is done through Settings → Broadcasting → Auto Tuning on most Samsung TVs, and the process takes 5 to 15 minutes.
  • You should scan for channels after moving to a new location, switching from cable to an antenna, or if channels have stopped appearing in your list.
  • A channel scan will find both over-the-air broadcast channels and any cable channels if your TV is connected to a cable box or cable input.
  • If a scan finds no channels, check that your antenna is connected properly or that your cable box is powered on and connected to the TV.

When You Need to Scan for Channels

Scan for channels whenever you move to a new home, switch from cable to an antenna, or notice that channels have disappeared from your list. A new location means different broadcast towers are in range, so the old channel list will not include local stations. If you have just installed an antenna or switched cable providers, a fresh scan ensures you get all available channels.

You may also want to rescan if you have added a new cable box, switched to a streaming service that uses your TV's tuner, or if your TV has not been scanned in several months. Channel lineups change—stations move frequencies, new ones launch, and others go off the air—so an occasional rescan keeps your list current.

Step-by-Step Instructions for Different Samsung TV Models

For 2022 and newer Samsung TVs: Press the Home button on your remote. Navigate to Settings (the gear icon). Select Broadcasting. Choose Auto Tuning. Select Start and wait for the scan to complete. The TV will display a progress bar and tell you how many channels it has found.

For 2019 to 2021 Samsung TVs: Press Menu on your remote. Go to Broadcasting. Select Channel Scan. Choose Start. Wait for the scan to finish. Your new channel list will appear automatically when done.

For older Samsung TVs (2018 and earlier): Press Menu. Select Tuner. Choose Channel Scan or Auto Program. Press Start. Some older models may ask you to select between cable and antenna—choose whichever matches your setup. The scan will run in the background, and you can use the TV while it works, though the picture may pause briefly as it searches.

What Happens During a Channel Scan

When you start a channel scan, your Samsung TV sends a signal through its tuner to search for all available channels on the frequencies used in your area. The TV locks onto each channel it finds, reads the channel number and name, and adds it to your list. This process repeats across the entire broadcast spectrum, which is why it takes several minutes.

During the scan, you will see a progress bar or a count of channels found so far. The TV may display "Scanning" or "Tuning" on the screen. You can usually watch TV or use other apps while the scan runs, though some older models may freeze the picture temporarily. Do not unplug the TV or turn it off during a scan—let it finish completely so all channels are captured.

Troubleshooting a Channel Scan That Finds No Channels

If your scan completes but finds zero or very few channels, the problem is usually a loose connection or a powered-off device. Check that your antenna cable is firmly plugged into the TV's antenna input (marked ANT or RF IN). If you are using a cable box, make sure it is powered on and that the cable from the wall outlet is connected to the box's input port, not its output port.

If you are using an antenna, try moving it to a different location or angle—even a small shift can improve signal strength. You can also check your TV's signal strength meter during the scan. Go back to Settings → Broadcasting and look for a Signal Strength or Signal Quality option. A reading below 50% usually means the antenna needs repositioning or the broadcast tower is too far away. If the signal is strong but no channels appear, the issue may be that no broadcast stations operate in your area, which is rare but possible in very rural locations.

Keeping Your Channel List Organized After a Scan

After a scan completes, your Samsung TV may list channels in numerical order, which can include gaps if some numbers are not used in your area. You can hide unwanted channels so they do not clutter your list. Press the remote's Menu button, go to Broadcasting, and look for Channel List or Edit Channels. Select channels you do not watch and choose Hide or Delete. Hidden channels can be unhidden later if you change your mind.

Some Samsung TVs also let you reorder channels by dragging them in the channel list menu. This is useful if you want your favorite stations at the beginning of your list. The exact steps depend on your TV model, but the option is usually in the same Broadcasting or Channel List menu where you hide channels. Take a few minutes to organize after a scan so your channel list matches how you actually watch.

Scanning When You Have Both Cable and an Antenna

If your Samsung TV is connected to both a cable box and an antenna, you need to scan each input separately. First, make sure your TV input is set to the cable box (usually HDMI 1, 2, or 3). Go to Settings → Broadcasting → Auto Tuning and run a scan. This will find and organize any cable channels your box provides. Then switch your input to the TV's antenna input (usually labeled TV or ANT), go back to Broadcasting, and run another scan. This will find over-the-air broadcast channels.

After both scans, your TV will have two separate channel lists—one for cable and one for antenna. When you switch inputs on your remote, you will see the channels for that input. Some newer Samsung TVs can combine both lists into one, which you can set up in the Channel List menu after scanning. Check your TV's manual or the Broadcasting menu for a "Combined List" or "All Channels" option if you want a single unified list.

Frequently Asked Questions

How long does a channel scan take?

A channel scan usually takes 5 to 15 minutes, depending on how many channels are available in your area and how strong the signals are. Rural areas with fewer stations may scan faster, while cities with many channels may take longer. You can watch TV or use apps while the scan runs on most Samsung models.

Will scanning for channels delete my recordings or settings?

No. A channel scan only updates your channel list. It does not affect recordings, apps, picture settings, sound settings, or any other TV configuration. Your personal preferences and saved content remain unchanged.

Do I need to scan for channels if I use a cable box?

If you use a cable box, the box itself handles channel management, and you may not need to scan your TV. However, if your TV has a built-in cable tuner and you want to watch cable channels directly without the box, you should scan. Check your cable box documentation or call your provider to see if your setup requires a TV scan.

What if some channels appear after a scan but have no picture or sound?

Channels with no picture usually mean the signal is too weak or the station is off the air. Try moving your antenna if you are using one. If the channel worked before and suddenly stopped, the station may have changed frequencies or gone off the air. Run another scan in a few weeks to see if it returns. If the problem affects most channels, check that your antenna or cable connection is find.

Can I undo a channel scan if I do not like the results?

Yes. You can hide individual channels you do not want to see, or you can run another scan to replace the entire list. There is no "undo" button, but you can manually delete channels one at a time using the Edit Channels menu, or run a new scan to start fresh. If you want to restore a previous channel list, you would need to manually re-add channels, so it is usually faster to just hide the ones you do not watch.
