Somedays ago, I wrote a similar article on Sony TVs where I discussed why a Sony TV might act strangely and reboot randomly.
But now, LG TV!
Both TV brands are quite similar in technical terms, so solutions for one may work for the other as well.
However, In this article, I will break down the reasons that might cause an LG TV to restart automatically and what you need to do to troubleshoot this issue.
Here we go! Let’s dive into it…
What causes an LG TV to restart automatically?
Typically, when an LG TV restarts randomly, malfunctioning firmware is the main culprit. However, other factors, such as hardware issues (e.g., a faulty capacitor) or external devices (e.g., a faulty HDMI cable or game controller), can also be responsible.
In some cases, you may also experience this issue while using an app like HBO Max or Netflix. This is likely due to a temporary system glitch on the TV or a corrupted core file in the app.
How to Troubleshoot LG TV keeps restarting issue?
To troubleshoot this, simply power reset the TV. Disconnect it from the power source for at least 60 seconds. During this time, press and hold the TV’s power button for about 15 seconds. Once done, plug the TV back in and power it on.
Power resetting is the basic step. Here are the other **troubleshooting tips** :
Step 1: Dust near the power board
Though this method requires some complex effort and DIY work, I wanted to mention it first!
Do you know why?
Before writing this guide, I watched several YouTube videos on this topic and checked some of the videos’ comment sections.
But a comment from Jessan caught my attention. According to him, cleaning the TV’s power board area solved his issue. He says,
“F**king dust for me…cleaned it. Used some ant chalk powder surrounding TV, inside aluminum plate that motherboard was mounted on. Gave it a thorough cleaning, including the vents and internal components. BAM, it worked.. no more random restarts.”
Here’s what you have to do:
- Take a screwdriver and then open the back panel of the TV.
- Check if there is any dust inside the power supply board.
- You might notice some ants there.
- Clean up these ants and dust properly.
Once done, reattach the back panel and power the TV again. Now check whether the problem has been fixed.
I think, without doing any further troubleshooting, this random rebooting problem will be fixed.
Step 2: Remote is malfunctioning
This is another culprit when an LG TV keeps rebooting!
If the remote is malfunctioning or a button is stuck, it can send out faulty signals that trigger the TV to restart automatically.
In the same video, aside from Jessan, Mikelli shared her findings.
She says,
Batteries out of the remote worked for me, it wasn’t the TV remote but the Amazon fire tv remote, once I removed them it stopped restarting. Issue fixed!
If you are using any streaming remote like Mikelli, do the same as she did! (Try this with the TV’s remote as well.)
First, check if any button is stuck. If none of the buttons are stuck, remove the batteries from the remote and press and hold the power button on the remote for approximately 20 seconds. After this, insert the batteries back into the remote and switch on the TV.
Step 3: Default reset
That’s the main part of this troubleshooting guide!
If none of the above methods worked for you and your LG TV is still constantly rebooting, restoring the firmware might help!
Basically, a factory reset will restore your TV’s firmware to the default state and fix any type of corrupted file, which will probably fix the issue.
However, if you don’t know how to reset the TV properly, refer to this article from WikiHow’s website. Once you reset the TV, check whether the problem has been fixed!
Note: If you have a game console or HDMI cable connected to your TV, be sure to disconnect them!
