This is weird to have your LG TV behaving like this especially when you are thinking to watch your favorite show.

But, don’t worry as there are proper troubleshooting steps that will help you to fix your LG TV and solve this issue of Turning on and then Off.

In this post, I would cover the causes with proper troubleshooting steps to help you fix the issue with your LG TV.

Let’s get started!

LG TV Turns on then Off Immediately

If your LG TV turns on and then off immediately, it could be caused by a few different things. First, there could be an issue with the internal memory. This can be remedied by resetting the TV. Second, the TV may be overheating. Again, this can be fixed by resetting the TV. Finally, there may be an issue with the TV driver. If this is the case, you will need to update the driver.

Here are the detailed causes with ways to fix that to solve the issue of LG TV Turning on then Off:

#1. Overheating of LG TV

The most common cause is that the TV is overheating. The overheating of a TV set can cause the television to malfunction.

If the TV is overheating, it will turn on and then off immediately to try to prevent damage to the TV.

If you leave your TV on for extended periods of time, it will eventually overheat. Another common cause of overheating in LG TVs is blockages in the ventilation system. 

If your LG TV doesn’t have enough airflow, the heat can build up inside, causing the TV to overheat. Finally, another cause of overheating in TVs is simply using them in a hot environment. 

If your TV is in a room that gets very hot, such as a sunroom or near a fireplace, the heat can cause the TV to overheat.

How to Fix Overheating of LG TV?

If the television is overheating, the first thing to do is try to identify the cause.

If the television is in a hot, humid environment, try to move it to a cooler location.

If the television is in a cabinet or enclosed space, try to increase the airflow around the television.

If the TV is overheating, it may be due to dust buildup on the internal components. 

To fix this issue, you can try cleaning the vents on the TV and making sure there is good airflow around the TV. You can also try using a TV stand that has built-in cooling to help keep the TV cool.

To clean the TV, unplug it from the power outlet and use a can of compressed air to blow out the dust. Once the TV is clean, try turning it on again.

#2. Faulty Power Supply

Another possible cause of your TV turning off immediately is a faulty power supply. If your TV is plugged into a power strip, make sure the power strip is turned on. 

How to Fix the Problem with Faulty Power Supply?

If your TV is plugged directly into a wall outlet, make sure the outlet is working by plugging in another appliance.

Also, check for any loose connection. It often happens that due to a loose connection, your LG TV can get disconnected after it is turned on. 

Try plugging your TV power cable into different power sockets in your power outlet. If your TV still won’t stay on, you may need to replace the power supply.

#3. Problem with LG TV internal Memory

One possible reason for your LG TV turning on and then off immediately could be an issue with the internal memory.

If the internal memory is corrupted or full, it could cause the TV to turn on and then off immediately. 

First of all, Smart TVs including LG TVs come with low internal memory and they can easily get occupied by cache build-up and software updates.

Also, there may be several unused software installed in your LG Smart TV that you don’t use often.

How to Fix Problems with LG TV Internal Memory?

If the problem is with the internal memory, you may need to reset the TV or clear the cache. 

To fix this issue, you can try resetting the TV to factory settings. This will erase all of the data on the TV, so be sure to back up any important data before resetting the TV.

You can also install any cache cleanup application on your Tv and clean the cache to free up internal memory.

To free up more internal memory of your LG TV delete some of the unused apps you have installed.

#4. LG TV Driver Issue causing it to turn on then off immediately

If you’re using an older model of LG TV, it’s possible that the drivers are outdated and need to be updated.

Also, the TV driver may have got corrupted which is causing it to turn off immediately after you turn your LG TV on.

How to Fix the Problem with the LG TV Driver Issue?

If the problem is with the TV driver, you may need to update the driver or reinstall it. To do this, go to the manufacturer’s website and download the latest driver for your LG TV model. 

Once the driver is downloaded, install it on your computer and then connect the TV to the computer using a USB cable. After the driver is installed, try turning on the TV again.

#5. LG TV Infected With Virus

This often does not happen as we plug rarely an external device into our LG Smart TV now.

Viruses or any type of malware can come from external devices like a Pen drive or external hard disk if that is already virus affected.

You may also bring viruses if you already have installed any other apps that are not from the Play Store on your TV.

How to Fix LG TV Infected With Virus?

To fix it, the best way is to remove any external devices attached to the TV and format those devices and scan those using an Anti Virus in your Laptop or your PC.

Now, about your LG Smart TV, do a factory reset. It will clean up all additional files that may be malware and bring the LG TV back to as it was before.

#6. Issue With the LG TV Hardware

If your TV turns on and then off immediately, and you’ve ruled out overheating, driver issues, and power supply issues, it’s likely that there is a problem with the TV itself.

This can happen once in a while.

How to Fix the Problem with Issue With the LG TV Hardware?

First, check the warranty of your LG TV. If your TV is under warranty, then you must register a complaint and log a ticket in LG’s official customer support.

If your TV is out of warranty, take your LG TV to the repair shop nearby for them to get a diagnosis of the issue and get an estimate from them.

Cross-verify the estimate with official customer support and give it to repair.

Generally, this can get fixed at a low cost. Otherwise, you need to look for a new TV.
