Vizio TV Turning Itself ON

There can be a list of the reasons why the TV is turning ON itself. Firstly, the TV is experiencing a power issue caused by the HDMI cables. The multiple color cables you use to attach it to the box are called HDMI cables, which provide a connection between the screen and the box.

Secondly, there can be software issues or glitches because you have not updated or reset the operating system for a long time. Lastly, the issue may be caused by activating timers. Let’s take a closer look and examine the problems, diagnose them, and then solve them with simple steps.

I have been fixing TVs for more than 5 years and in this long duration, I have observed that people do not bother to check their TVs and bring them to the professional after a few minutes of experiencing a problem.

These problems, such as the TV turning ON itself, are very simple to solve, which one can fix at home without a single tool. Proper guidance and familiarity with technology can help you eliminate these issues within a few minutes.

Faulty Power Supply

There is an 80% chance that the power cable you are using with the TV is not working properly. A faulty power cable can open the channels of power for the device when you have turned the device off. Basically, it is the power cable that turns the TV on, not the button, so if the cable is damaged or it is faulty you may experience such issues.

There is no solution other than changing the power cable. Basically, a power cable is hard to repair, and it is inexpensive, why bother repairing the cable then? You should change the power cable and check if the issue has been resolved, use the best quality power cable for desired results.


Consumer Electronics Control may cause a list of problems in which the TV turning ON itself is the common one. Basically, it is a control system that allows us to connect multiple devices at the same time with the help of an HDMI cable and we can use a single remote controller to operate all of them at the same time. Because all the devices are interconnected, the HDMI-CEC can malfunction.

For example, if you have connected Xbox and TV and you turn off the TV but forget to shut down the Xbox, it is possible that the Xbox sends signals to the TV and the device itself turns ON again. These issues are commonly observed when a faulty HDMI-CEC connection is identified.


  • Step 1: Turn ON the TV and go to the Main Menu of the operating system with the help of your remote controller.
  • Step 2: Go to the “System” section, and then click on the “CEC”.
  • Step 3: A notification with two buttons may appear asking for turning it off or removing it. Tap on the turn-off button and the HDMI-CEC has been disabled.

I Don’t Want To Use TV With Remote Controller

It is possible that you are unfamiliar with the complex use of remote controllers. In such conditions, you can use the Vizio TV application to turn the HDMI-CEC off. The application is available on the Play Store or the App Store, download and enter the PIN to connect it to the TV and follow my steps.

  • Step 1: Go to the TV Settings.
  • Step 2: Open the “System” and then “CEC”.
  • Step 3: As you click on the “CEC” button, it will ask permission to turn it off. Confirm the command and the HDMI-CEC has been disabled.

You have checked the power cable and disabled the HDMI-CEC, but the problem is still there. That is because you have unintentionally turned on a timer changing the TV settings. If you are unfamiliar with this unique feature, it can turn ON and OFF the TV according to the set time.

Here, you may question that you have not set any timer on the TV, so why does it work? Basically, people who do not know about the complicated settings of the TV, mistakenly turn the timer on. Once it has turned on, you cannot stop the Vizio TV from turning itself ON without deleting the timer settings.


  • Step 1: Go to the Main Menu of your TV.
  • Step 2: Select “Settings“, then “Timers” option.
  • Step 3: Turn OFF the timer.

Updating The Operating System

The operating system requires updates with the passage of time.
