Hi Billy P, If apps are not working correctly, we recommend first checking for firmware updates on your TV. Go to Home > Settings > Support > Software Update. If you do have the latest firmware, then you can next try a cold boot. There are two ways to cold boot your TV: 1) Using 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 then on again. This should take about 5 seconds. 2) Using 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. For more help, please contact Samsung TV Support at 1-800-SAMSUNG, available 8 AM – 12 AM EST, seven days a week.

Hi Rwal21, Thank you for reaching out to us. If your TV appears to turn off by itself, try disabling some of the TV's energy efficiency functions. See if Sleep Timer has been enabled. The Sleep Timer automatically turns the TV off after a specific period of time. Go to: Settings > All Settings> General > System Manager > Time > Sleep Timer If the Sleep Timer has not been enabled, see if Auto Power Off or Off Timer has been enabled and disable it. - Settings > All Settings> General > Power and Energy Saving > Auto Power Off - Settings > All Settings> General > System Manager > Time > Off Timer If the TV continues to turn off by itself continuously, please get in touch with Samsung Customer Support at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week.
