Why does my LG 43LF5900 LED TV turn off suddenly?
- JJustin CookAug 20, 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.
