Soft Reset TV (Cold Boot) vs. Hard Boot

  • Cold Boot (Using Remote Control)

    • Press and hold the power button on the TV remote for about 5 seconds until the TV turns off and on again.
    • This refreshes the TV's RAM and cache but doesn't erase them 
       
  • Hard Boot (Unplugging TV)
    • Unplug the TV from the power source.
    • Wait for at least 30 seconds before plugging it back in.
    • This erases the TV's RAM and cache, providing a more thorough reset than a cold boot.

Step 5. Enter the name of the app and install it. 

Note: 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.
