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 mode. 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:
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.
If you turn 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.
On your TV, navigate to Settings, select Support, select Software Update, and then select Update Now.
If an update is available, it will automatically install and the TV will reboot.
Occasionally, the latest update will be available first on our download center on Samsung.com. So when having an issue, it's always a good idea to check there.
To download the latest software updates, visit the Samsung Download Center. You can either select your Product type and then search for your Smart TV or monitor, or select Search your model number to access the support page for your specific model. On the Support page, locate the firmware file for your device under Downloads. If you find multiple firmware versions, install the newest version. Select Download next to the firmware version to download the compressed file.
Your device will search the USB drive for the update files. Follow the on-screen instructions to install the updated software. Updates usually take a few minutes; please do not turn off the TV until the update is complete. When the update is finished, it will restart automatically.
To delete the app, navigate to and select Apps on the TV, and then select the Settings icon in the top right corner. Find the app you are having an issue with, and then select Delete.
If Delete is grayed out, this is a recommended app. Select Reinstall instead.
When you reset Smart Hub, the TV will sign you out of your Samsung account and all of your apps. Make sure you have the current login information for all of your app accounts before you proceed.
If you need login information for a third-party app, please visit the app developer's website. If you need your Samsung account information, visit the Samsung account support site.
The steps for resetting Smart Hub will vary depending on what year your TV was made:
When resetting Smart Hub, you may be asked to enter the 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.
Try using the app you are having a problem with again to see if the problem you were having is still occurring.
If the app is no longer experiencing an issue, you are all set!
If the app is still having an issue but other apps seem to work normally, continue to Step 6.
If your app is still having trouble, but the other apps on your TV are performing normally, you should reach out to the developer of the app that is giving you trouble.
At this time they may be able to confirm whether there is an issue specifically with their app that they can provide additional information for or they can work with us toward finding a resolution.
