In this article we explore the possible causes and solutions when the TV turns off on its own. We will review aspects such as the electrical connection, the HDMI cable, the timer, the remote controls, software or hardware problems, as well as the importance of going to the manufacturer, especially if the device has a warranty. Find out how to fix this common problem with your TV!
Check the electrical connection
One of the first steps you should take when you have the problem of the TV turning off by itself is to check the electrical connection. It may seem obvious and, in fact, it is, but sometimes at this point serious errors occur that condition the operation of the television.

Often, intermittent power outages or a bad plug can be the cause of this inconvenience. Therefore, you should do the following to rule out that this is the true cause:
- Power cord. Check that it is firmly connected to both the power outlet and the TV.
- Wear and tear. Check to find damaged or worn wires that may interfere with the electrical connection.
When everything seems to be in order, it’s best to try plugging the TV into a different outlet or consider that there’s a more complex problem with the device.
Check out the HDMI cable
Let’s look at another case. Sometimes, when the TV turns off on its own, it may be related to the HDMI connector. This cable is responsible for transmitting the video and audio signal from the connected devices.
It’s important to note that when the HDMI cable isn’t working properly, the TV usually doesn’t turn off completely. However, it does cause the image to disappear and cause the panel to be completely black. This conveys the feeling that the TV turns off by itself.
Either way, do the following to download issues:
- Check the status of the HDMI cable. Is it properly plugged into both the TV and the input source?
- Look for apparent damage. Follow the cable by hand to find damage or kinks, as this can affect the quality of the connection and cause intermittent power outages.
- Replace the cable. Even if there is no apparent damage, the cable may have some internal problems. So, buy an HDMI cable and check if the problem persists.
Check that the timer isn’t turned on
Suppose the HDMI cable and power connection are working fine. Another aspect to consider is whether the timer is activated. Some TVs have an auto-off feature that allows you to schedule a certain time for it to turn off.
This feature is usually activated for two reasons:
- The user has set an automatic shutdown time. In that case, go to your TV’s settings menu and check if the timer is enabled and if it coincides with the times when you experience the unexpected shutdown. If so, turn off the timer or adjust the settings according to your preferences.
- Energy saving. Another reason is that the TV detects that there is no activity and turns off to minimize electricity consumption. In such cases, it is enough to start playing a piece of content to prevent it from happening.
Check if Google Assistant or Alexa is turning off your TV
Be very careful with smart devices! Why do we say that? If you have a smart device at home, such as Google Assistant or Alexa, there is a possibility that the TV is being turned off.
Here are some solutions:
- Make specific and clear requests. Voice assistants receive voice commands and sometimes misinterpret them. Does the TV turn off on its own just when you command something to your speaker? You may be getting confused.
- Review your configured routines. Try to remember if there are scheduled actions to turn off connected devices. Make sure there are no routines or actions that are programmed to turn off the TV without your knowledge.
- Disconnect your TV from the platform. Maybe in the past you did an automatic shutdown setting. Keep in mind that even if you no longer use your speaker or have sold it, the programs you’ve deployed will still be active. The best thing to do is to unlink the TV from the platform in question.
Has the power gone out?
If you find yourself in the situation where the TV turns off on its own, it’s important to consider whether there has been a power outage in your area. This is especially important if it is daytime, where there are usually no more lights on in the home and it is more difficult to detect an interruption in the supply.
The checks involve trying to use other appliances to see if they have also been turned off. Wait a few minutes to see if the power is restored and, in the event of an extended outage, contact the power company for more information.
Remote control issues
Remote controls, even those on other devices, could be turning off your TV without you knowing. Or maybe the device’s own remote control has stopped working properly. How do you know if this is the real problem?
Here are some suggestions:
- Remove batteries from other remotes, especially if they are often near the TV that turns off on its own. Any controller that works with infrared can give you problems in this regard.
- Using your TV remote, try pointing directly at the device. Check to see if other devices turn off.
- Check to see if there are any buttons stuck or stuck on the TV remote. This could cause unexpected behavior, including automatic shutdown.
- Don’t forget about batteries. Replacing the batteries in the remote control can also help resolve issues related to button malfunctions.
Software or hardware failures
Finally, when the TV turns off on its own, it can also be attributed to software or hardware errors.
- Software. These errors can be related to faulty updates or incorrect configurations. An effective solution is to reset the device or download the latest version of the operating system.
- Hardware. These are failures that have to do with defective components, manufacturing deficiencies or internal wear and tear.
Don’t forget that, in Spain, the law establishes a 3-year warranty for products such as televisions. This means that if the equipment has problems within this period, the manufacturer is responsible for making the necessary repairs free of charge. If you experience persistent difficulties with the TV, contact the manufacturer’s customer service for guidance on how to proceed.
