  If your LG LED TV turns off unexpectedly, several factors could be at play. First, the power supply might be interrupted, so check the power control settings. Also, the Sleep Timer or Timer Power Off feature may be activated within the Timers settings. Another possibility is that the Auto Power Off feature is enabled in the General -> Eco Mode settings, depending on your specific model. Finally, if the TV is on but not receiving a signal, it will automatically shut down after 15 minutes of inactivity.
