1. In order to stop your LG television set from randomly shutting down, the first step we recommend taking is to make sure that the TV isn’t using the Auto Power Off feature.
To disable it, you need to take the following steps:
- Go to the Settings menu on your LG A2, B2, C2 or G2.
- From the Settings menu, select General.
- Next, go to OLED Care.
- Afterwards, head to Device Self Care.
- Inside the Device Self Care menu, go to Energy Saving.
- You then need to select Auto Power Off.
- Lastly, make sure that the Auto Power Off setting has been disabled.
2. We also recommend turning off the Screen Off feature, which you can do so by taking the following steps:
- Open the Settings menu on your OLED television set.
- Head to General from the Settings menu.
- After getting to General, you then need to head to OLED Care.
- You then need to select Device Self Care.
- Afterwards, select Energy Saving.
- Once you get to the Energy Saving menu, select Screen Off.
- Finally, make sure that the Screen Off has been disabled.
3. Furthermore, you should make sure that you didn’t set any timers that will cause your A2, B2, C2 or G2 OLED to turn off at seemingly random times.
In order to check if you have a timer active, you need to take the following steps:
- Launch the Settings menu on your TV.
- Inside of Settings, head over to General.
- In General, select System.
- From the System menu, select Time and Timer.
4. If you have HDMI-CEC or SimpLink enabled on an HDMI device that is connected to your television set, then this feature may be causing you television set to shut down unintentionally.
To fix this particular issue, go to the settings menu on the connected HDMI device to see if there is an option to disable HDMI-CEC or a similar function.
5. You should also make sure that the power cable is securely connected to the back of your television set as well as the power outlet.
6. Moreover, you can try using a different power outlet as the current one your television set is connected to could be malfunctioning.
7. Make sure that the television isn’t overheating as hot temperatures may force it to shut down by itself.
To see how you can prevent your LG OLED from getting too hot, and cool it down when it does, you can take a look at this guide.
7. If your A2, B2, C2 or G2 OLED television set is still randomly turning off on its own, then we suggest contacting LG for additional support.
If your problems turn out to be hardware related, you may have to get your TV repaired or replaced.
