10 Ways to Fix an LG TV That Keeps Turning Itself Off

So you’re in the middle of watching something and for no reason whatsoever, the TV turns itself off. Or, worse. It powers off even before you can put something on. You turn it on, it turns itself off. How can you break this vicious cycle?

Check out the 10 tips listed in this article. They will walk you through getting your TV to turn on and stay on.

#1 Check the AC Cord Is Plugged in Properly

Before you start dismantling the back of the TV and changing the motherboard, we’ll start with some of the simplest fixes. These are often the things that we overlook and could quickly solve the problem.

Let’s have a look at the first one. Checking that the AC cord or the power cord is plugged in properly. You should double-check that the power cord is firmly plugged into the wall socket and the back of the TV. If it is not, you could experience problems with your TV cycling on and off.

#2 Ensure the AC Cord Isn’t Damaged

The next step is to ensure that your AC cord isn’t damaged. If it is, it will begin to malfunction and mess with the proper running of your TV. Check for any fraying or exposed wire.

When checking for damage, make sure you plug the TV out first. If you find any damage along your power cord, you should discontinue using the TV. You will need to replace the cord.

#3 Test the Power Socket

Ok, so what if the power cord itself isn’t the problem, but the power socket is? If your power socket isn’t working as it should do, it could be the culprit of your TV on and off problems.

To test your power socket, do the following.

  1. Plug the TV out of the power socket
  2. Plug another device into the power socket, such as a hairdryer
  3. Turn the hairdryer on to the maximum speed and heat. If the hairdryer works as it should, you can conclude that there isn’t a problem with your power socket. If it doesn’t, you will need to call an electrician to repair the faulty connection.

#4 Reset the TV

Resetting your TV is a good way to clear it of anything that may be stopping it from working properly.

Here’s how you can reset your LG TV.

  1. Turn off the TV using the power button
  2. Plug the power cord out of the wall socket. Keep it unplugged for 1 minute.
  3. Plug the TV back in
  4. Turn it back on using the power button

Some LG TV owners have found that deactivating the Quick Start + function on the TV puts an end to their TV on/off problems.

Here is how you can deactivate Quick Start + from your LG TV.

  1. Press the “HOME” button on your remote control
  2. Choose “SETTINGS”
  3. Navigate to “GENERAL”. You should then see the Quick Start + option in the dropdown menu. Click this option then choose “OFF”.

#6 Disable the Auto Power Off

The Auto Power Off feature on an LG TV is a setting that will turn your TV off automatically. It will do so if there is no user input after the pre-selected amount of time. This is to prevent your TV from staying on overnight or during the day when no one is watching it.

To disable this feature on your LG TV, do the following.

  1. Press the “HOME” button on your remote control
  2. Choose “SETTINGS”
  3. Click on “GENERAL” then “TIME”
  4. Then choose “TIMERS”
  5. Select “AUTO POWER OFF” and click to disable the option

#7 Disable the Power Off Timer

The power off timer on an LG TV will turn the TV off automatically at a set time during the day. It will turn the TV off at the predetermined time every day specified in the timer. This will turn the TV off regardless of whether you were actively watching it or not.

It is possible that someone selected and set this option by accident. So, here are the steps you need to disable the power off timer.

  1. Press the “HOME” button on your remote control
  2. Choose “SETTINGS”
  3. Click on “GENERAL” then “TIME”
  4. Then choose “TIMERS”

#9 Update Your Software

Performing a software update may solve the power on/off problem that you’ve been having with your LG TV. This is because software updates do the following.

  • Increase the security of your appliance
  • Improve the stability of your software
  • Remove outdated features

Here’s what you can do to reset your LG TV.

  1. Press the “HOME” button on your remote control
