Why does my LG 43LH5800 turn off suddenly?
- JJeffrey WallaceAug 10, 2025
If your LG LED TV turns off suddenly, the power supply may be interrupted, so check the power control settings. Also, check if the Sleep Timer or Timer Power Off feature is enabled within the Timers settings. If the TV is on but not receiving a signal, it will automatically turn off after 15 minutes of inactivity.
