  If your LG LED TV turns off suddenly, check your power control settings to ensure the power supply isn't being interrupted. Also, verify that the Sleep Timer or Timer Power Off is not activated in the Timers settings. Depending on your model, check if the Auto Power Off is activated in the General -> Eco Mode settings. Also, the TV will turn off automatically after 15 minutes of inactivity if there is no signal.
