The fastest way to find all available channels on your Samsung TV

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 then search for all available broadcast channels in your area and save them automatically. 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 process is the same: you are telling the TV to search the airwaves for signals and store what it finds. You do not need any special equipment — just an antenna connected to the TV's antenna port (the round connector labeled RF In or ANT).

Key Takeaways

  • A channel scan searches for all broadcast channels available in your area and saves them to your TV automatically.
  • You need an antenna connected to your TV's antenna port before you start the scan.
  • The scan takes 5 to 15 minutes and you can watch TV or use other apps while it runs in the background on most Samsung models.
  • If you do not see channels you expect, try moving or repositioning your antenna and running the scan again.
  • Channel scans do not find cable or satellite channels — only broadcast channels that come through the air.

Check your antenna connection before you start

Before you begin a channel scan, make sure your antenna is plugged into the correct port on the back of your TV. The port is usually labeled RF In, ANT, or Antenna and looks like a round connector with a threaded ring. If you are using an indoor antenna, position it near a window or in a high spot in your room — the higher and more open the location, the more channels you will likely find.

If your TV is connected to cable or satellite, you do not need to scan for channels — your cable box or satellite receiver handles that. A channel scan on a Samsung TV only finds broadcast channels that come through the air, not paid TV services.

Step-by-step channel scan for most Samsung TVs

Press the Home button on your remote to open the home screen. Then navigate to Settings — it usually appears as a gear icon in the top right corner of the screen.

Once in Settings, look for Broadcasting or Channels. Select it, then find Auto Tuning or Channel Scan. The exact wording depends on your TV model year, but both terms mean the same thing. Select it and the TV will ask you to confirm — choose Yes or Start to begin the scan.

The TV will now search for channels. You will see a progress bar showing how far along the scan is. On most newer Samsung TVs, you can continue using the TV while the scan runs — you can watch another input, use apps, or just wait. When the scan finishes, the TV will show you how many channels it found and ask if you want to save them. Choose Yes.

What to do if the scan finds few or no channels

If your scan found very few channels or none at all, the problem is usually antenna position or signal strength in your area. Try moving your antenna to a different location — higher up, closer to a window, or away from metal objects and electronics that can block signals. Then run the scan again.

You can also check what channels broadcast in your area before you scan. Visit tvfool.com or fcc.gov/media/engineering/dtvmaps, enter your address, and you will see a map of which channels should reach you and how strong the signal should be. If the map shows no channels in your area, broadcast TV may not be available where you live, and no antenna adjustment will help.

Rescanning after you move or change your antenna

If you move to a new home or replace your antenna, run the channel scan again. Your old channel list was built for your previous location or antenna, and channels available in a new area may be different. Go back to Settings > Broadcasting > Auto Tuning and start a fresh scan.

Some Samsung TVs also have an option to Clear Channel List before you scan. If you see this option and you are rescanning in a new location, clear the old list first so the TV does not mix old and new channels together.

Channel scan on older Samsung TV models

Older Samsung TVs may use slightly different menu names. Instead of Settings, you might see Menu on the remote. Instead of Broadcasting, look for Channels or Tuner. The scan option might be called Channel Search, Tuner Setup, or Initial Setup.

If you cannot find the scan option in the menus, check your TV's manual — you can search for your model number on Samsung's website and read the PDF. The manual will show you the exact menu path for your specific TV year and model.

Frequently Asked Questions

Can I scan for channels if I have cable or satellite?

You can run a channel scan, but it will only find broadcast channels, not your cable or satellite channels. Your cable box or satellite receiver already has its own channel list, so you do not need to scan the TV itself. If you want to watch broadcast channels on the TV without going through your cable box, then yes, run a scan.

How often should I rescan for channels?

You only need to scan once when you first set up your TV, and again if you move to a new location or change your antenna. Broadcast channels do not change often, so you do not need to rescan regularly. If a new local station launches, you can rescan to find it, but this is rare.

Why does the scan take so long?

The TV is checking every frequency in the broadcast spectrum to find signals. Depending on how many channels are available in your area and how strong those signals are, this can take anywhere from 5 to 15 minutes. The TV is working the whole time — you just cannot see progress on every frequency it checks.

Will the scan erase channels I already have?

When you run a new scan, the TV will replace your old channel list with the new one. If you want to keep channels from your old list, write down their numbers before you scan. After the scan finishes, you can manually add any missing channels through the TV's channel menu if needed.

What if my TV does not have a Broadcasting menu?

Some very old Samsung TVs or TV models sold in certain regions may not have an Auto Tuning option. Check your TV's manual for the correct menu path, or contact Samsung support with your model number. They can tell you whether your TV supports channel scanning and how to access it.
