      If your LG LED TV turns off suddenly, it could be due to a few reasons: * Check the power control settings to ensure the power supply isn't being interrupted. * Verify if the Auto sleep feature is enabled in the Time settings, as this might be causing the TV to turn off automatically. * If the TV is on but not receiving a signal, it will automatically turn off after 15 minutes of inactivity.
