Hi! You can set the Sleep Timer to turn off after a set period of time. Additionally, you can enable Auto Power Off to have the TV turn itself off if there has been no activity for a set period of time. This is one of your TV’s energy efficiency functions. Using your TV remote, navigate to Settings > General > System Manager > Time > Sleep Timer, and then select the amount of time you would like the TV to stay on before powering itself off. You can set the sleep timer up to 180 minutes, after which the TV will turn off.
