How to Scan for Channels on Samsung TV

Most TV comes with over-the-air (OTA) channels that do not require any monetary subscription. So far, the programming of OTA channels has come a long way. It has transitioned from the static waves aired in the 90s to being broadcast in HD.

The era of paid cable subscriptions is gradually phasing out the number of people who watch OTA channels. Nonetheless, some people still tune in to enjoy some of the content aired on these channels. So how do you get these channels on your Samsung TV?

Scanning for Channels on TV

In the ‘90s, you had to tune manually for radio and television channels. Today, you can effortlessly scan for available channels by allowing the TV to run through every possible television frequency and then making a list of available channels.

Note that this list needs to be updated regularly to include any new previously unavailable channels. To update your list, you will need to scan your TV all over again.

Most importantly, you will require an antenna to receive the frequencies of local channels in your area. When you move, for instance, to another country, the local frequencies will be different. So, you have to scan for channels every time there is a change in local broadcast frequencies in your area.

How to Set Up an Antenna

  • Most antennas come with a manual that shows which side goes into which
  • Once you are done coupling your antenna, proceed to mount it
  • You can either mount it outside or inside, depending on how strong the local frequency in the area is
  • You may need to connect a coax cable to the antenna if it does not come with one
  • Connect one end of the coax cable to the ANT IN port on the back of your TV
  • Then change the Source on your TV to TV by pressing the source/home button on your remote control, then select TV

3 Ways to Troubleshoot Scanning Issues on Samsung TV

Scanning for Channels on Samsung TV Troubleshooting

If, after going through the processes described above, you still cannot find any channels, there might be something you are doing wrong or a glitch somewhere.

1. Change the RF Cable Slot

Generally, if you insert the antenna in the wrong slow, there is a high chance that you might not get any output.

Most TVs feature two slows ANT 1 IN (AIR) and ANT 2 (Cable). So, if you are using an antenna, the right slot should be ANT 1 IN, while if you are using a cable, ANT 2 is the correct slot.

2. Restart your TV

The issue might be with your TV. A minor glitch can hinder your TV from scanning. So, to resolve this issue, it is recommended that you restart your TV. To do that, follow the steps below:

  • Power off the TV using the power off button on the remote
  • Alternatively, you can use the button at the side of the TV
  • Plug out the power cable of the TV from the outlet
  • Wait for about 5 minutes
  • Then plug your TV back to a power source
  • And power it on

Then you can follow the steps described above to scan for channels

3. Factory Reset

This is a last resort solution if the two solutions above do not fix the issue. A factory reset will automatically erase all pre-saved settings and installed apps on the TV.

All configurations will be permanently lost; the TV will power on with its default settings as if you just bought it. If you can, it is advisable to create a backup of your data on an external drive.

Then you can plug in the external drive to your TV after the reset is done to restore your data.

Below is how to initiate a factory reset on your TV:

  • Go to Settings
  • Press General
  • Click on Reset
  • Enter your Pin (default pin is 0000)
  • Select OK to confirm

Your TV will immediately go into a reset mode. Alternatively, you can carry out a self-diagnosis to initiate a reset. You can do this by

  • Going to Settings
  • Click on Support
  • Select Self Diagnosis
  • Then click on the Reset option on the menu


Scanning for channels is straightforward as long as you do not miss any of the steps described above. Also, you can always troubleshoot your TV if you are experiencing a glitch.
