Cold booting your TV is a little different than simply turning it off and back on. When you turn it off, it is really in standby. A cold boot actually shuts the TV down and reboots it, like restarting a laptop. This can solve issues you may be having with apps, glitches in the menu, picture issues, etc.
There are two ways to cold boot your TV.
With the Remote: For most people, the easiest way is to hold down the Power button on the Samsung TV remote until the TV turns off and on again. This should only take about 5 seconds.
With the Plug: If you do not have the remote, unplug your TV from the wall outlet or surge protector, leave it unplugged for 30 seconds, and then plug it back in.
Note: If you switch off a surge protector with other devices plugged into it (such as your router), give them time to power up and reconnect before testing any functions on your TV.
Check for software updates on your TV.
On your TV, navigate to Settings > Support > Software Update, and then select Update Now.
If an update is available, it will automatically install and the TV will reboot.
Delete the app from your TV and download it again
Delete the app.
Navigate to and select Apps, then select the Settings icon.
Navigate to the app you are having an issue with and select Delete. (If Delete is grayed out, this is a recommended app. Select Reinstall instead.)
Download the app again.
Press Return on the remote and select the Search icon in the top right corner.
Enter the name of the app.
Select the app and then select Install.
Open the app and try again.
Check to see if the issue you were having with the app is still occurring.
Reset Smart Hub on your TV
Gather the login information for all of your apps.
When you reset Smart Hub, you will sign you out of your Samsung Account and all of your apps, not just the one you're having trouble with. Make sure you have the current login information for all of your accounts before you proceed. If you need this information, visit the app developer's website. If you need your Samsung account information, visit Samsung Account Support.
Reset Smart Hub.
Navigate to Settings > Support > Self Diagnosis > Reset Smart Hub.
Enter your TV's PIN.
The default PIN is 0000. If you have ever changed the PIN on your TV, enter your PIN to start the reset.
After the initial setup process, try the app again.
Note: You may need to download the app again after the reset.
If you are still having an issue with the app after completing the Smart Hub reset, reach out to the app developer to see if they are aware of the issue. Many times a fix is likely to be available soon.
Note: Only apps available in the App Store can be installed on the smart TV.
