You’ve set up your Samsung TV and are ready to start watching your movies and shows, but now your TV won’t change inputs. Or maybe your TV was working before and for some reason it has stopped working.

Don’t fret. There are methods to help you troubleshoot your TV and fix the problem. Just follow these steps and your TV should start working.

Check The Remote

First, you will want to check your remote. Most often, it is the remote that is not working. This could be due to malfunction or just a low battery power. You will want to change the batteries in your remote. A fresh set of batteries can save you a lot of time.

If you’re not sure if the remote is the issue, try changing the input via the TV buttons. Another way to change the input settings is to connect your TV to the application on your phone. Your phone can become a remote for your television. If you can change the input on the TV either way, then your remote may be the culprit. 

Restart The TV

One easy step is to restart your Samsung TV using either your remote, phone application, or the button on the TV. You will need to follow these steps to restarting your TV to make sure you truly reset it all the way and not just turn it on and off within minutes:

  • Turn off your Samsung TV.
  • Remove the power chord from the electrical outlet.
  • Wait at least 5 minutes before turning it back on. The TV needs to cool down.
  • Plug the electrical cable back into the outlet.
  • Turn on your Samsung TV.
  • Test the source inputs.

If the issues continue to arise, you can try the other methods.

Power Cycle Your Remote

The Samsung remote may need to be reset as well. You can do a quick reset with your remote and see if this fixes any problems. Here is how to properly get your remote working again:

  • Remove each battery from the battery compartment on your remote.
  • Hold down the power button of your remote for about 8 seconds.
  • Put the batteries back in.
  • Test the remote out to see if the input changes.

Power Cycle With The Buttons

If you have tried to do the manual reset on the remote and it doesn’t work, there is another method you can try. Do the first steps of taking the batteries out of your remote. Instead of only pressing the power button for a few seconds, you will want to press each button several times.

You will then put the batteries back into the remote. Try out the buttons to see if everything has reset and worked. If it has not, there are a few other steps that you can try.

Factory Reset TV

When all else fails, you can try to factory reset your Samsung TV. Remember this will bring your TV back to its original state when you first bought it. All passwords and applications will be logged out. Some of the applications may also be deleted from your TV and will have to be redownloaded. 

Here are the steps you need to take to reset your Samsung TV:

  • Go to the TV’s settings.
  • Click on the General tab.
  • Click on “reset” and enter your PIN (which you should have created when you first set up your TV).
  • Confirm that you want to reset your TV by pressing the OK button.
  • Restart your TV and check to see if the input sources work.

If you had never set your PIN, it should be by default 0000. If you are having difficulties figuring out how to reset your TV, you can also go to the Self Diagnosis section and search for the information to reset your TV.

Check HDMI Cable

If you can change the input settings, but nothing seems to pop on that source, you may want to check your cables. Try using a different HDMI cable or other cable and see if it works. Cables do go bad after a few years, or you may have gotten a faulty cable. If another cable works, then you know that was the issue.

Call Samsung

You should have a number in the manual that can help you with any issues you have. Call the number and see if they can help you with any other ways to fix your input. They may provide a different solution or offer you alternatives like replacing the TV (if under warranty).

If your TV is brand new, it may be easier to simply return the current one and replace it with a new one. It is more expensive to fix a current TV than to buy a new one. Plus, it is less of a hassle just to return that TV and get a new one.


Technology, although it makes life easier, can be quite temperamental. If you are still having trouble with your TV, call the company. If you have an older TV, it may be ready for a new one. There are many solutions to fixing your TV, but sometimes, a new one may be the best for everyone.
