If you’re experiencing frequent shutdowns with your LG TV, you may be wondering, “Why does my LG TV keep turning off?” Dealing with a TV that keeps turning off can be frustrating, but understanding the underlying reasons is the first step to solving the issue. We’ll look at common causes of your LG TV shutting off unexpectedly in this tutorial. By identifying these factors and implementing solutions, you can prevent interruptions to your viewing experience. Let’s delve into why does my lg tv keep turning off and how to fix it.

Disclaimer: The steps outlined in this guide are a starting point for addressing the issue of LG TVs turning off unexpectedly. The diagnosis of complex electronic devices is not always straightforward, and there can be numerous nuances. Proceed with caution and, if in doubt, get expert advice.

Why Does My LG TV Keep Turning Off

Common Causes of Why Does My LG TV Keep Turning Off

There are several reasons why your LG TV may be turning off on its own, each with varying degrees of commonality. Troubleshooting requires an understanding of the root problem. Here are a few of the most common causes along with more information about them.

  • Power issues: The most apparent reason for a TV turning off unexpectedly is a power issue. This could stem from a faulty power cord that’s not delivering electricity properly, an outlet that’s failing to provide a consistent power supply, or even an internal power supply issue within the TV itself. Regularly checking these components can prevent or address such issues.
  • Overheating: Like all electronic devices, LG TVs generate heat during operation. If the TV’s built-in cooling system, which might include fans and heat sinks, fails to dissipate this heat effectively, the internal temperature of the TV can rise to unsafe levels. To prevent damage, the TV will automatically shut down. Ensuring your TV has adequate ventilation and is not placed near heat sources can mitigate this problem.
  • Remote or button malfunction: Problems with the remote control or the actual buttons on the TV itself are less likely reasons. Sometimes, these buttons can become stuck or the remote might send unintended signals due to physical damage or a software glitch within its system. Regular maintenance and care can help avoid such malfunctions.
  • Software update: TVs today are as much software-driven as they are hardware-dependent. If your LG TV has recently undergone a software update, it’s possible that the new software version is causing compatibility issues or has bugs that lead to the TV turning off. Keeping an eye on software updates and reporting any issues can help address these glitches.
  • Timer settings: Many LG TVs come equipped with built-in timers that provide the convenience of scheduling when your TV turns on or off automatically. However, if these timer settings are accidentally configured or malfunction, they could result in your TV turning off at unexpected times. Double-checking these settings can prevent such surprises.
  • Weak or fluctuating power source: Lastly, if your TV is connected to a power source that is weak or experiences fluctuations, it might not receive the steady flow of electricity needed for optimal operation. This can result in your TV turning off intermittently. To help guarantee a steady power supply for your TV, consider using a voltage regulator or surge protector.

By understanding and addressing these potential issues, you can often resolve the problem of your LG TV turning off unexpectedly, ensuring a more reliable and enjoyable viewing experience.

Solutions for LG TV Turning Off

Once you have identified the potential cause of the problem, you can then move on to implementing a solution. Some common solutions for LG TV turning off include:

  • Check the power source: If you suspect a power issue, start by checking the power cord and outlet. Verify that they are both securely linked and in good working order. Try plugging the TV into a different outlet or using a new power cord to see if that solves the problem.
  • Clean the vents: A buildup of dust and debris in the TV’s vents might result in overheating. Regularly cleaning them out with compressed air or a cloth can help prevent overheating and prolong the life of your TV.
  • Replace batteries: If the issue seems to be related to the remote control or buttons on the TV, try replacing the batteries in the remote first. Should that fail, it might be necessary to have the TV or remote controlled serviced.
  • Factory reset: Try a TV factory reset if the problem was brought on by a firmware update. This will restore it to its original settings and can often resolve any compatibility issues.
  • Adjust timer settings: Double-check that timer settings are not causing the issue. If you wish to prevent the TV from shutting off at a certain time, make sure they are disabled.
  • Invest in a surge protector: Take into consideration purchasing a surge protector to shield your TV from power fluctuations. This will regulate the flow of electricity to your TV and prevent damage caused by sudden surges or drops in power.

If your LG TV keeps turning off and the previously mentioned solutions haven’t resolved the issue, don’t worry; there are still several additional troubleshooting steps you can undertake to potentially fix the problem:

Check for updates:

One of the first things you should do is ensure that your TV’s software is completely up to date. Manufacturers frequently provide software upgrades to address recognized problems or enhance overall functionality. Locate the software update check option by navigating through the TV’s settings menu. If you discover any pending updates, proceed to install them and then check to see if the problem with your TV turning off has been resolved.

Contact customer support:

It could be necessary to contact LG customer service if updating the firmware doesn’t resolve the problem. Their team is equipped to provide detailed troubleshooting advice specific to your model. Moreover, if your TV is still under warranty, they can guide you through the process of getting it repaired or replaced at no extra cost to you. Prepare your TV’s model number and a description of the issue before you call or email them to ensure a smoother support experience.

Ask an expert:

In some cases, the issue might be too complex for standard troubleshooting to resolve, or you might not feel confident enough to attempt some of the more involved steps on your own. It makes sense to bring in a qualified technician at this point. A certified expert can come to your location, thoroughly inspect your TV, and pinpoint the exact cause of the problem. They have the skills, equipment, and know-how required to finish repairs swiftly and securely. Hiring a professional might incur additional costs, but it’s often worth it to extend the life of your TV and avoid the hassle and potential mistakes of DIY repairs.

Remember, taking these steps not only helps to potentially fix your LG TV but also ensures that you’re taking all necessary precautions to safeguard your investment in your home entertainment system.

Additional Tips and Tricks

  • Always make sure to properly shut down your TV instead of unplugging it or using the power button. This will ensure that your TV lasts longer and help prevent any software bugs.
  • Regularly clean and dust your TV, paying particular attention to the vents and ports.
  • Refrain from plugging in too many gadgets at once to your TV since this may overload the power supply and lead to unplanned shutdowns.
  • If you live in an area with frequent power outages or fluctuations, consider investing in a UPS (uninterruptible power supply) to protect your TV from damage.


In conclusion, understanding why does my LG TV keep turning off is key to resolving the issue. By addressing common factors such as power settings, overheating, or software updates, you can prevent frequent shutdowns and enjoy uninterrupted viewing.
