Are you tired of your LG TV turning off by itself, disrupting your favorite shows or movies? You’re not alone. Many LG TV owners have experienced this frustrating issue, leaving them wondering what’s causing it and how to fix it. In this article, we’ll delve into the possible causes of this problem and provide you with troubleshooting steps to resolve it.
Understanding the Possible Causes
Before we dive into the solutions, it’s essential to understand the potential causes of your LG TV turning off by itself. Here are some of the most common reasons:

One of the most common causes of an LG TV turning off by itself is overheating. Modern TVs, especially those with LED or OLED panels, can generate a significant amount of heat during operation. If the TV’s cooling system is not functioning correctly, or if the TV is placed in a poorly ventilated area, it can cause the TV to overheat, leading to a shutdown.
Causes of Overheating
- Blocked air vents: Make sure that the air vents on your TV are not blocked by furniture or other objects.
- Dusty environment: Regularly clean the TV’s air vents and surrounding area to prevent dust buildup.
- High ambient temperature: Avoid placing your TV in direct sunlight or near a heat source.
Power Issues
Power issues can also cause your LG TV to turn off by itself. This can be due to a variety of reasons, including:
Causes of Power Issues
- Loose connections: Check that all cables, including the power cord, are securely connected to the TV and the wall outlet.

Why does my LG TV keep turning off by itself?
LG TVs can turn off by themselves due to various reasons, including overheating, loose connections, or issues with the power supply. It’s also possible that the TV’s built-in protection features are causing it to shut down to prevent damage from excessive heat or voltage fluctuations. To troubleshoot the issue, try checking the TV’s surroundings to ensure proper airflow and verify that all cables are securely connected.
If the problem persists, it may be worth checking the TV’s settings to see if the auto-shutoff feature is enabled. This feature is designed to turn off the TV after a certain period of inactivity, but it can sometimes malfunction and cause the TV to turn off unexpectedly. You can try disabling this feature or adjusting the timer to see if it resolves the issue.
How do I reset my LG TV to fix the turning off issue?
Resetting your LG TV can often resolve issues with the TV turning off by itself. To reset your LG TV, press the Home button on your remote control, then navigate to Settings > General > Reset to Initial Settings. Enter your PIN code (if prompted) and confirm that you want to reset the TV. This will restore the TV’s default settings and may resolve any software-related issues that are causing the TV to turn off.
Keep in mind that resetting your TV will erase all of your customized settings, so you’ll need to set up your TV again after the reset. If you’re not comfortable resetting your TV, you can try a soft reset by unplugging the TV from the power outlet, waiting for 30 seconds, and then plugging it back in. This can sometimes resolve issues with the TV’s power supply or overheating.
Can a faulty power cord cause my LG TV to turn off by itself?
Yes, a faulty power cord can cause your LG TV to turn off by itself. If the power cord is damaged or loose, it can disrupt the flow of electricity to the TV, causing it to shut down unexpectedly. Check the power cord for any signs of damage, such as frays or cuts, and try plugging it into a different outlet to see if the issue persists.
If you suspect that the power cord is faulty, try replacing it with a new one to see if it resolves the issue. Make sure to purchase a replacement cord that is compatible with your LG TV model. If the problem persists after replacing the power cord, it may be worth checking the TV’s internal power supply or consulting a professional for further assistance.
Can overheating cause my LG TV to turn off by itself?
Yes, overheating can cause your LG TV to turn off by itself. LG TVs have built-in protection features that are designed to prevent damage from excessive heat. If the TV’s internal temperature exceeds a certain threshold, it may shut down to prevent damage to the internal components. Check the TV’s surroundings to ensure proper airflow and verify that the vents are not blocked.
If you suspect that overheating is causing the issue, try moving the TV to a well-ventilated area or using a fan to improve airflow. You can also try cleaning the TV’s vents to ensure that they are not clogged with dust or debris. If the problem persists, it may be worth consulting a professional to diagnose and repair any underlying issues with the TV’s cooling system.
Can a software issue cause my LG TV to turn off by itself?
Yes, a software issue can cause your LG TV to turn off by itself. LG TVs run on complex software that can sometimes malfunction or become corrupted. If the TV’s software is not functioning properly, it can cause the TV to shut down unexpectedly. Try checking for any software updates and installing the latest version to see if it resolves the issue.
If the problem persists after updating the software, you can try resetting the TV to its default settings or performing a factory reset. This will erase all of your customized settings, so be sure to set up your TV again after the reset. If the issue persists, it may be worth consulting a professional to diagnose and repair any underlying software issues.
Can a hardware issue cause my LG TV to turn off by itself?
Yes, a hardware issue can cause your LG TV to turn off by itself. LG TVs have complex internal components that can sometimes malfunction or fail. If the TV’s hardware is not functioning properly, it can cause the TV to shut down unexpectedly. Try checking the TV’s internal components, such as the power supply or motherboard, to see if they are functioning properly.
If you suspect that a hardware issue is causing the problem, it may be worth consulting a professional to diagnose and repair any underlying issues. In some cases, it may be more cost-effective to replace the TV rather than repairing it. Be sure to check your warranty or contact LG support to see if you are eligible for any repairs or replacements.
What should I do if my LG TV is still under warranty and is turning off by itself?
If your LG TV is still under warranty and is turning off by itself, you should contact LG support to report the issue. They will be able to diagnose the problem and provide any necessary repairs or replacements. Be sure to have your TV’s serial number and warranty information ready when you contact support.
LG support may ask you to troubleshoot the issue or provide additional information to help diagnose the problem.
