A:Answer The LG 50 inch Class 4K Smart UHD TV (49.5'' Diag), Model # 50UM6900PUA has a Sleep Timer and a Timer Power On / Timer Power Off function. The Sleep timer can be set to turn the TV off after 10, 20, 30, 60, 90, 120, 180 or 240 minutes have elapsed. To use the Timer Power On / Timer Power Off function, the clock on the TV has to be set correctly. The Clock menu has two options: 1) Auto (Synchronizes the TV clock to the digital time information sent by the TV station), and 2) Manual (Sets the time and date manually if the auto setup does not correspond to the current time). If you receive the time signal from an Over-the-Air (OTA) antenna, then the options are Time Zone and Daylight Saving. You can select a day and time for when to set the TV to automatically turn on/off the TV. You can set the Time and Day Menu to repeat daily, or set it to repeat for Mon-Fri or Mon to Sat, Sat Sun, or Sun...^IFV
