If you're experiencing issues with your Samsung TV, such as slow operation or inability to launch apps, you can perform a reset using the TV's remote control.

This feature performs a software reset (reboot) rather than a factory reset.

Before proceeding, please check that you have the correct remote control paired with the TV.

Turn Off the TV

Press and hold the Power button on the remote control for more than 3 seconds until the TV screen turns off.

Software updates provide bug and security fixes for your device. Keep your TV’s software up to date to prevent errors.

This process removes old and useless data that causes problems and replaces it with fresh data. 

Note:

  • If Delete is grayed out, this is a recommended app. Select Reinstall instead.
  • Make sure that you have your login information before deleting or reinstalling an app. These steps will sign you out, and so you will need to sign back in.

Press the Home button on the remote control and select Menu → Settings → Support → Device Care → Self Diagnosis → Reset Smart Hub.

Enter your PIN. The initial PIN is 0000.

 

Note: 

  • The default PIN is 0000.
  • You may need to download the app again after the reset.

Note: Device screenshots and the menu are only a sample in English - they are also available in the language of your country.
