A soft reset shuts the TV down completely and reboots it, rather than placing it just into standby mode. This can solve issues that you may be having with apps. There are two ways to soft reset your TV.

  • Press and hold the power button on your remote until the TV turns off and on again. This should only take about 5 seconds. 
  • Unplug your TV from the power socket for 30 seconds, and then plug it back in.

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

Step 1. Press the Home button and navigate to the Settings.

Step 2. Go to Support, and then select Software Update.

Step 3. Click Update Now to start updating your TV.

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

Step 1. Press the Home button and navigate to Apps.

Step 2. Go to Settings.

Step 3. Navigate to the app, and then select Delete.

Step 4. Press the return button on your remote and select the Search icon and enter the name of the app and install it.

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.

Resetting Smart Hub will sign you out of every app that you use on your Smart TV, not just the app that you want to fix. Therefore, make sure that you have the current login information for all of your accounts before you proceed to reset.
