Scanning for channels on your Samsung TV

To scan for channels on your Samsung TV, go to the home screen, open Settings, select Broadcasting, then choose Auto Program (or Channel Scan, depending on your model). The TV will search for all available channels in your area and save them automatically. The scan usually takes 5 to 15 minutes, and you should not turn off the TV during this time.

The exact menu names vary slightly between Samsung TV models and years, but the process is the same: you are telling the TV to search for broadcast signals and store what it finds. This works whether you use an antenna, cable box, or satellite receiver connected to your TV.

Key Takeaways

  • Access the channel scan through Settings > Broadcasting > Auto Program on most Samsung models, though some older TVs label it Channel Scan instead.
  • The scan searches for all available channels in your area and takes 5 to 15 minutes; do not turn off the TV until it finishes.
  • You should scan for channels after connecting an antenna, cable box, or satellite receiver for the first time, or if you move to a new location.
  • If the scan finds no channels, check that your antenna or cable connection is plugged in firmly and positioned correctly before trying again.

Step-by-step channel scan on Samsung TVs

Start by pressing the Home button on your Samsung remote to reach the home screen. From there, navigate to Settings using the arrow buttons and press Enter. Look for an option called Broadcasting or Channels—the exact name depends on your TV model year.

Once you open Broadcasting, you will see Auto Program or Channel Scan. Select it and press Enter. The TV will ask you to confirm that you want to start the scan. Press Yes or OK. The scan will begin, and a progress bar will appear on your screen showing how many channels have been found. Leave the TV on and do not unplug it or press any buttons until the scan completes.

When the scan finishes, the TV will display a message saying the scan is complete and show you how many channels were found. Press OK to close the message. Your new channels will now appear in your channel list, and you can navigate through them using the up and down arrow buttons on your remote.

When to scan for channels

Scan for channels the first time you set up your Samsung TV with an antenna, cable box, or satellite receiver. You should also scan again if you move to a new location, since different areas have different broadcast channels available.

If you add a new cable box or satellite receiver to your TV, or if you notice channels are missing or no longer work, run the scan again. Some viewers also rescan after a major weather event or if their antenna was moved or adjusted, since signal strength can change.

Troubleshooting a channel scan that finds no channels

If your scan completes but shows zero channels found, the first thing to check is your connection. Make sure the cable from your antenna, cable box, or satellite receiver is plugged firmly into the back of your TV. Look for a port labeled HDMI, Video In, or Antenna In, depending on what device you are using. Push the cable in until you hear or feel a click.

If you are using an antenna, move it to a different location or angle it differently. Antennas are sensitive to position, and even a small shift can improve signal strength. Wait a few seconds after moving it, then run the scan again. If you are using a cable box or satellite receiver, make sure that device is turned on and set to the correct input channel (usually Channel 3 or 4 on older boxes, or HDMI 1 or 2 on newer ones).

If the scan still finds no channels, try unplugging your TV and the connected device for 30 seconds, then plug them back in and wait for them to fully restart before scanning again. This resets the connection and often solves temporary signal problems.

Organizing channels after a scan

After the scan completes, your Samsung TV will list all found channels in numerical order. You can hide channels you do not watch, reorder your favorites, or lock channels to prevent accidental viewing. These options are usually found in Settings > Broadcasting > Channel List or Edit Channels.

To hide a channel, highlight it in the channel list and press the Options or Menu button on your remote, then select Hide Channel. To create a favorites list, press the star or heart icon on your remote while watching a channel, or highlight the channel in the list and select Add to Favorites. This makes it faster to jump between the channels you watch most.

Rescanning if channels disappear

Sometimes channels that were working stop appearing or become unwatchable. This can happen if your antenna shifted, if a cable connection loosened, or if a broadcast station changed its signal. Before rescanning, check all physical connections again and make sure nothing is blocking your antenna.

If connections look good, run the channel scan again using the same steps described above. The TV will search for all available channels and replace your old list with the new results. Any channels you hid or added to favorites will be reset, so you may need to reorganize them afterward.

Frequently Asked Questions

Can I scan for channels without an antenna or cable box?

No. Your TV needs a signal source to scan for channels. You must have an antenna connected for over-the-air broadcasts, a cable box for cable channels, or a satellite receiver for satellite channels. Without one of these, the scan will find nothing.

How long does a channel scan take?

Most channel scans finish in 5 to 15 minutes. The time varies depending on how many channels are available in your area and how strong the signals are. Larger cities with more channels may take longer than rural areas.

Will rescanning delete channels I have already saved?

Yes. Running a new scan replaces your entire channel list with the results of the new scan. Any channels you hid, reordered, or added to favorites will be reset. Write down your favorite channels before rescanning if you want to remember them.

What if my TV keeps saying "no signal" after I scan?

Check that your antenna or cable connection is plugged in all the way and that the device providing the signal (antenna, cable box, or satellite receiver) is turned on. Try moving your antenna to a different location. If the problem continues, the signal in your area may be weak, and you may need a stronger antenna or a different antenna position.

Do I need to scan again if I change the input source?

No. Once you have scanned for channels on a particular input (like HDMI 1 or Antenna), those channels are saved. You only need to scan again if you connect a new device to that input or if you move to a new location.
