You can restart your TV when necessary. Restarting has the same effect as unplugging your TV power and then plugging it in again.
To restart your TV, navigate to Settings > System > Power and then select System restart. Highlight Restart, and then press OK to confirm restart.
While the TV restarts, the screen goes dark for a few seconds, and then displays the startup screen for a few more seconds. When the restart operation completes, your TV displays the activity you selected in Customizing your TV.
