However, like any other brand, LG’s products are not perfect and can sometimes have issues that affect our daily lives.

LG TV Keeps Turning Off

The problem of your LG TV turning off unexpectedly can be frustrating and concerning. But you don’t need to fret about it. By following some simple steps, you can restore your beloved LG TV and get it working again.

Below are the required Troubleshooting steps

1. Check the Cables connected to your LG TV

In most cases, TVs, including LG TVs, don’t turn off without a reason. One of the most common reasons for an unexpected shutdown is if the TV is not receiving the power it needs.

Another possibility is that the TV is receiving signals to turn off from a device connected to it through HDMI-CEC, even when no request has been made.

To address these issues, it’s important to check the cables connected to the TV. Faulty or damaged cables can reduce the power supply to the TV, causing it to shut down unexpectedly.

Make sure to inspect the entire length of all the cables connected to the TV and look for any visible signs of damage.

If you find any damaged power or HDMI cables during your inspection, it is crucial to replace them.

2. Change the Electrical Outlet

When you’re trying to fix electronic devices, it’s important to pay close attention to details and use a systematic approach. Sometimes, the problems may not be caused by the faulty device itself but by external factors.

If you have an LG TV that keeps turning off, there are some things you can do to try and fix it. First, check the cables that are connected to the TV.

Look for any signs of damage or wear on the wires, as this could indicate a problem. Make sure all the connections are secure and there are no torn parts that could disrupt the signal.

However, even if the cables look fine, the problem might be coming from somewhere else. In that case, you need to investigate other possibilities. One potential cause could be the electrical setup, particularly the power supply.

Check if the wall socket or surge protector could be causing issues. You may not have considered them before, but they play important roles in distributing power.

To rule out these components as sources of the problem, you can try using different power sources.

3. Disable Quick Start+

Quick Start + is a convenient feature available on certain TVs that offers the option to put the TV in standby mode instead of completely turning it off.

With this feature enabled, the TV remains in a low-power state, ready to be quickly powered on without going through the entire startup process.

This feature proves to be quite useful in situations where you desire instant access to your TV. By utilizing Quick Start +, you can bypass the waiting time typically required for the TV to start up.

However, it could be the cause of the issue you are facing.

Here is how to go about it:

  1. Hit the Home or Smart key on the remote.
  2. Navigate to Settings General.
  3. Choose Quick Start and turn the feature off.

4. Turn Off the Auto-power-off Feature

LG TVs come equipped with an auto-power-off feature designed to automatically turn off the TV when it’s not in use.

The primary purpose of this feature is to conserve power and reduce energy consumption. However, there are instances where the TV may unexpectedly shut down due to its perception that it is not being used.

To limit or check if the issue is occurring there, you might have to turn off the auto-power feature.

Here is how to go about it:

  • Utilize the Home or Smart button on the remote control.
  • Navigate to the General Settings.
  • Select the Auto Power Off feature and disable the setting.

5. Disable the Power Off Timer Feature

Some LG TVs have a feature called the Power Off Timer, which can be used alongside the Auto Power Off feature. This feature allows you to set a specific time in advance, and the TV will automatically turn off after that time.

The power-off timer can be handy in different situations.

For example, if you enjoy watching TV before falling asleep, you can set the timer to ensure that the TV shuts down after a certain period.

This helps save energy and prevents the TV from running unnecessarily when not in use.

However, if your TV is turning off by itself and you don’t want it to, the Power Off Timer might be causing the issue, and it might be best to temporarily turn it off.

Here is how to go about it

  • Press the Home or Smart key on your remote control.
  • Head to Settings, followed by Time.
  • Set the Off Time to ‘Off.’

6. Check for a Software Update on your LG TV

Even if you’ve turned off the auto-power-off and timer settings on your TV, it may still shut down unexpectedly. This could be due to a software bug in the TV system.

Software bugs are flaws or errors in the programming code that can cause electronic devices to behave unexpectedly. In this case, a bug might be causing your TV to turn off when it shouldn’t.

To resolve this issue, the best solution is to update the TV’s software with newer versions that fix the bugs. Software updates often include improvements and patches specifically designed to address known issues and bugs.

Since you are aware of this, here is how you should go about that.

  • Ensure your television is linked to the web.
  • Push the Home or Smart key on the remote control.
  • Navigate to Settings > All Settings.
  • Select General.
  • Scroll to About this TV.
  • Enable Allow automatic updates and opt for Check for updates.
  • Wait for the system to determine and install updates if found.

NB: When the TV finishes updating and restarts, go through the TV and see if the issue still persists.

7. The Cache has Filled up the Storage.

Your TV doesn’t have a lot of storage space inside, and it can get quite full quite fast when you install and update apps that you want to use with your TV.

These apps make their own special files that they use often, and these files take up space in the TV’s storage.

When there isn’t enough space left in the storage, the TV can’t work properly, so it turns off to try and fix the problem caused by the lack of storage.

To fix this, you need to clear the browser and app caches in your LG TV’s storage. This means getting rid of the extra files that the apps store to free up space.

Here is how to do that:

  • Press the Home or Smart key on your LG remote.
  • Launch the web browser or web engine. 
  • Access the Settings menu.
  • Select the Clear Browsing Data option and confirm the prompt that appears.
  • Push the Home or Smart key again and launch the TV’s settings.
  • Pick the application manager.
  • Go through each app from the list and visit the storage settings to clear its cache.
  • Repeat this for all the apps on your TV until enough space has been freed.

NB: Try restarting the TV once more and observe if it shuts off while you are watching something on it.

8. Factory Reset LG TV

Although factory resets are a viable option, it is advisable to ensure that this is done as a last resort. Resetting the TV will restore it to its original factory settings, requiring you to sign in to all your accounts once again.

Not only that, you might have to reinstall all the applications that were removed during the reset process which might be daunting.

But it could get the job done.

Anyway, here is how to go about it

  • Push the Home or Smart key on the remote control.
  • Choose Settings.
  • Navigate to General > Reset to initial settings.
  • Agree to the reset alert and wait for the television to reboot.
