If your LG LED TV turns off unexpectedly, there are a few potential reasons. First, the power supply might be interrupted, so check the power control settings. Also, verify that the Sleep Timer or Off Time hasn't been activated in the TIME settings. Finally, if the TV doesn't receive a signal for 15 minutes, it will automatically turn off.
