Why Toshiba TV Automatically Turns Off

Last Updated Feb 25, 2022

The last thing you expect to happen with your Toshiba TV is for it to turn off unexpectedly. A few different things can cause this issue, some which are fixable, and some which would require a repair or replacement.

Your Toshiba TV will automatically turn off if: 

  • The Timer is set in the Settings
  • Energy Saving Mode is on
  • The TV is heating up
  • There is a faulty power supply
  • There is a firmware bug
  • The CEC setting is in use

We know this can be a frustrating issue, so let’s dive into possible solutions for why this is happening with your TV.

Changing the Settings of your TV

Most Toshiba TV’s have a “Clock” or “Timer” setting in the Menu options. This is for your convenience if you have a habit of leaving the TV on when you aren’t in the room, or falling asleep at night with the TV on.

This ensures the TV turns off after a designated amount of time, as to not waste electricity and to extend the life of your TV. You don’t want it to be on when you aren’t watching it, so Toshiba added this feature. 

Make sure this is properly set, or off, in order to not have the TV turn off at an unwanted time.

Energy Saving Mode will also turn the TV off after it idles for a certain amount of time not using it to save electricity.

CEC Setting

There is also an option in your settings which is called CEC that allows external inputs such as video game consoles for example, to control your TV.

Your input device may very well be the cause if the TV decides to power off when the input device is turned off. There also may be a miscommunication with the devices that results in the TV turning off at random times.

Disable the CEC option and see if this changes anything. If you would like to learn more about Toshiba, check out this article.

Power Issues With Your Toshiba TV

Problems can lie both with the internals of the TV and also how the TV is receiving power.

Here are some ways to troubleshoot your Toshiba TV’s power:

  • Checking the outlet where your TV is plugged in is a good place to start when tackling a power issue. Trying another outlet can possibly isolate the problem if it works elsewhere.
  • You may have a surge protector hooked up to the power cable to prevent a surge of electricity to the TV and to knock out any static on the line. Removing the surge protector and seeing if this solves the problem can help isolate the issue also.
  • After you have looked into those areas of troubleshooting and you are still having malfunctions, a reset of the TV may be necessary. This can be done in the Toshiba TV’s Settings in the Menu options. TV’s many times just need a good reset to get them back to working properly.
  • Another problem that could lie within the issue of the power is the power supply of your TV. If this is an issue, you have likely tried everything else first before looking into this possibility.

If it is a problem such as this, with the internals of your TV, it would need to be repaired, or even replaced, in order to fix the problem.

Updates to Your Toshiba TV

Oftentimes after a TV is released on the market, the manufacturer will release an update to fix known problems with their TV that have been discovered by customers after the TV has been used for some time.

Updates in the form of firmware upgrades can be found on Toshiba’s website. These updates usually require them to be downloaded to a flash drive and installed from your TV, or there will be an option in the settings to check for updates if your TV is connected to the internet.

Making sure your TV is updated to the latest version of firmware is a process you should complete whether you have fixed the issue or not, since updates can fix issues you may not even be aware of.

Additional Troubleshooting

If you have tried all these things and nothing seems to fix the problem, there are a couple more things you can try to get your TV into working order.

Here is some additional troubleshooting you can do to your Toshiba TV:

  • What you can do is start disabling options on your TV and removing input devices one by one. For instance, if you have Wi-Fi on; disconnect it. External speakers; disconnect them. 
  • Disconnect your streaming devices and video game consoles also.

You want your TV operating at a very basic level to see if the problem is indeed with your TV or if it lies elsewhere in your setup.


As you can see, there are several things you can try in order to keep your TV from powering off when you don’t want it to. If anything, this should help you isolate your problem. Good luck troubleshooting!
