But the more important question here is how to solve this issue for a better user experience in the future.

Vizio Smart TV Keeps Turning Off and On, How to Fix?

There might be many reasons why your Vizio Smart TV automatically turns on and off so frequently. We have tried to cover all the possible reasons behind the scenes and the proper ways to handle them. However, it’s often quite hard to find where you are lacking, so you might have to try out a few before finding the exact issue. Therefore, let’s not waste any more time on further ado and get going already.

1. Check the Vizio Smart TV Plug

One of the most basic and common causes of such issues might be a loosely connected plug. If your Vizio TV plug is not properly connected to the power socket, it might catch and break the connection more frequently. This is one of the possible reasons why your TV keeps turning on and off as you try to watch something. Therefore, make sure to check the plug and fit it again nicely. Again, switch on your TV and check if the problem persists.

2. Check for any stuck key in the TV Remote

Another possible issue causing such an issue might be a stuck power button on your TV remote. Check if the power button on the remote is fine or stuck. If it is stuck, press it and free the button. A stuck key might keep giving continuous signals to the TV, manipulating it to turn off and on every time.

3. Keep other Device Remotes away from your TV

Firstly, if you have more than one Vizio Smart TV at your home, make sure not to keep the remotes close enough. Even operating two different Vizio TVs at a close distance might alter the signals of the other TV. Perhaps you can consider turning off one TV and putting its remote away for a while just to ensure the actual problem.

Apart from that, Vizio TVs are also CEC-enabled by default. This allows any other device to turn the TV on or off through some power signal. Therefore, if you are using multiple devices at the same time, chances are it might be the cause of the problem. In that case, simply turning off the CEC mode shall help.

To turn off CEC in Vizio Smart TV, we can take the following steps:

  • Go to Settings.
  • Now, go to System.
  • Next, look for CEC and disable the option.

4. Check for a Sleep Timer on your Vizio Smart TV

Almost all smart TVs today provide a sleep timer mode. This automatically turns the TV off after a certain period is reached as set by the user. If the user sets this time too short, it may keep switching off the TV after every round of the specified time is over. Therefore, if you are still experiencing the issue, you can turn off the sleep timer mode or increase the period.

To change the sleep timer settings, you can follow the steps below.

  • Go to TV Settings.
  • Select Timers
  • Now, click on the Sleep Timer option. Either turn it off or set an appropriate time limit.

5. Turn on Eco Mode

It isn’t very common, but if other devices over the same network are casting to your Vizio TV, it might occasionally cause such issues. In such a scenario, the best way to fix it is by turning on the Eco mode on your TV. To enable Eco mode on your Vizio Smart TV, follow the steps mentioned:

  • Open Settings.
  • Go to System.
  • Now, go to Power Mode.
  • Select Eco Mode and turn it on.

Turning on Eco mode will ensure that your TV is turned on before any casting takes place. If this was all done by casting another device, you shall see the results soon.

6. Turn on Quickstart Mode

There is not much explanation behind this method. But sometimes, when turning Eco mode on fails you, then enabling the Quickstart mode works in very rare cases. All you need to do is:

  • Open TV Settings.
  • Navigate to System.
  • Go to Power Mode.
  • Finally, select Quickstart Mode and enable the feature.

7. Factory Reset the TV

This is the last resort if none of the above tricks fix your issue. Running a factory reset will change all your settings to the default and remove all your data. But it is a powerful technique; hopefully, it must work even if none of the others do. You can follow the steps below to factory reset your Vizio Smart TV:

  • First of all, go to TV Settings.
  • Now, go to System.
  • Click on Reset & Admin.
  • And finally, select Reset TV to Factory Defaults.

8. Ask for Professional help

Last but not least, if running a factory reset also doesn’t have any effect, you should rather ask for professional help. Contact the Vizio Support team and explain the entire issue. Let them have a look at the problem to come up with an appropriate fix.


Issues like this mostly occur due to some small causes most of the time. And if you are lucky enough, you should find your cure in the first three to four methods themselves. However, if all of them fail you, it might be a different issue, and we advise you to try all the fixes listed above.

You might even have to ask for professional help in the worst scenario. However, that is not the case generally for most users. So, share your thoughts on these methods and if you have something more to your sleeves.
