There are two options available for turning the LG CX 77 inch Class 4K Smart OLED TV w/ AI ThinQ® (76.7'' Diag), Model # OLED77GXPUA off at your desired time. The option is the Sleep Timer that you can use to turn the TV off with after a selected amount of time. You can set the Sleep Timer to turn the TV off from 10 minutes to 30 minutes in 10 minute increments, from 30 minutes ro 120 minutes in 30 minutes increments, or from 120 minutes to 240 minutes in 60 minutes increments. The other option that was mentioned in an earlier response is to use the Power Off Timer which you can use to set your desired time for the TV to turn off automatically. If you use the Power Timer ON function to turn the TV on, if you do not press a button after 120 minutes after the TV is turned on with this function, the TV will turn off automatically. To ensure that the TV does not automatically turn off, you will need to set the 2 hours Auto Power Off setting to off. The time for the TV must be set correctly for this function...^IFV
Sorry, there was a problem. Please try again later.Under Settings>General>Time>Power off timer to desired time to shut tv off. There is also an auto power off timer that, if enabled, that will shut TV off after 2 hours if no button has been pressed for 2 hours.
