My LG TV Keeps Turning Off By Itself

My LG TV Keeps Turning Off By Itself

An LG TV turning off on its own after you turn it on can be an annoying issue. Before bringing your TV to a repair center it’s always best to perform some troubleshooting steps since in most cases this type of problem can easily be fixed.

Here’s what you need to do to stop LG TV turning off on its own issues.

Solution 1: Soft reset your LG TV

One factor that can cause the LG Smart TV power problem is a software glitch. This can be due to the TV’s internal memory being overloaded or the TV’s operating system has crashed. In order to fix this, you just need to restart your LG TV.

Force reboot TV

Press and hold the power button on the LG TV for at least 10 seconds.

When the LG TV turns off unplug its power cord from the power source. You will know it is off when the power button lights is no longer lit.

Wait for a minute before plugging the power cord back to the power source then turn on the LG TV.

Try checking if the LG TV keeps turning off issue still occurs.

Solution 2: Plug LG Smart TV into another power outlet

If your LG TV turns off after you turn it on then its possible that this can be caused by a loose power cable. Make sure that the power cord is connected securely to the power outlet to prevent any power issue.

Power strips have also been known to cause power related issues on the devices connected to it. If your LG TV is getting its power from a power strip then I suggest you unplug the TV and connect it straight to the AC wall outlet instead. If this doesn’t work then try connecting the TV to a different power outlet.

Solution 3: Disable the auto power off timer feature

It’s possible that this issue is caused by the auto power off feature or sleep timer that has been enabled. This feature allows you to save electricity as it will automatically turn off the TV at a specified time. Try turning off the auto power off feature to check if this is what’s causing the problem.

Turn off auto power off feature

Press the “HOME” button on your remote control

Choose “SETTINGS”

Click on “GENERAL” then “TIME”

Then choose “TIMERS”

Select “AUTO POWER OFF” and click to disable the option.

Solution 4: Make sure the LG TV is not overheating

One of the reasons why your LG TV will turn off after you turn it on is overheating issues. Try feeling your TV and check if it is warm. If it is, then turn it off first to cool it off. You should also make sure that the sun or any other heat source does not hit the TV directly.

Solution 5: Update your LG TV software

It’s important for your LG TV to run on the latest software updates as this will have several enhancements as well as bug fixes that could fix the power issue you are experiencing.

Update LG TV software manually

Go to Settings using the LG TV remote control.

Go to All settings.

Go to Support.

Select Software update.

Select Check for Updates. If an update is available then select Download and Install.

After getting the latest software update try checking if the LG TV will now work properly.

Solution 6: Perform a factory reset on your LG TV

In case the power issue persists then you will need to reset to initial settings your LG TV. This will bring back the TV to its default factory settings and usually fix any problems caused by a corrupted LG TV software.

Factory reset LG TV

Press the Settings button on your remote.

Go to All Settings.

Open the General tab.

Select Reset to Initial Settings.

Click OK to confirm.

After the factory reset has completed try to check if the TV set is now working properly.

Solution 7: Contact LG TV support

There are instances when the problem can already be caused by a hardware problem. If this is already a hardware issue caused by a damaged main board, power supply board, or other component then you will need to contact the nearest LG TV customer service center and have the TV fixed.
