Fix #1: Power Cycle Your Vizio TV

  1. Power off your Vizio TV and unplug all cables that are linked to it
  2. Unplug the TV from the power outlet as well  
  3. Search for the power button at the back of your TV
  4. Press and hold the power button for 3-5 seconds
  5. Now, leave your TV in that state for 30 minutes
  6. After 30 minutes, replug your Vizio TV and reattach all the cables
  7. Finally, turn on your Vizio TV

Power cycling successfully fixed the Vizio TV keeps turning off issue for many users. However, if it fails to fix the problem, you should move on to the next fix.  

Fix #2: Remove Remote Batteries

There are several reasons why your Vizio TV keeps restarting, but this is one of the most prevalent. According to numerous Vizio TV owners, a malfunctioning Vizio remote, or any other remote with IR blasters, might cause your Vizio tv to switch off at random. 

You should first remove the batteries in the TV remote alongside the batteries in other remotes to see if that is the issue (do this while the TV is still powered on). You must also ensure that there are no obstructions between the path of your TV and the remote blocking the IR signals. 

Fix #3: Check Remote Power Button

What if it turns out that the power button on your remote control is jammed? Check the power button on your Vizio TV remote and feel it to see if it is stuck. The best way to check this is by feeling the power button and other buttons on the remote. 

If you feel there’s a difference between the push of the power button and other buttons, then there is a chance that dust particles have gone under it and are thus hindering its function. You must clean your remote and bring the power button back to its working condition. You can use a cotton earbud to clean the remote and tiny spaces between the buttons.

Troubleshooting a vision tv turning off by Itself

Below are some conventional troubleshooting methods for the Vizio TV turning off issue. Although these are standard troubleshooting techniques across most entertainment devices, they come in super handy to fix issues. 

Hard Reset The TV

When facing an issue where your Vizio TV turns off by itself, you should hard reset the device. The process of hard resetting your Vizio TV necessitates pressing the power button located in the device’s back panel.  

How to hard reset Vizio TV:

  1. Turn off your Vizio TV
  2. Unplug the power cord from the power outlet and leave it unplugged
  3. Find the power button on the backside of your Vizio TV. The buttons look alike, so you’ll need to look closely to figure the power button
  4. Press and hold the power button on your TV for around 10 seconds 
  5. Restart your TV after 10 minutes

If the hard reset does not solve the problem, try the following method.

Check Connected Devices

There’s a chance that a connected streaming device like Chromecast or Fire TV Stick will cause the Vizio TV turning off issue. Or it could also be due to other connected devices like a Blu-Ray player causing the issue. Sometimes any internal glitch in the connected devices can cause your Vizio TV to shut down abruptly at regular intervals. 

To check if it is indeed a device connected to your Vizio TV that’s causing the trouble, unplug all the connected devices from your TV and leave them unplugged for an hour to see if the TV stops turning off. If it does, then it means that one of the connected devices is responsible for the problem. You can find the problematic device by plugging the devices independently one by one. 

Note: There may also be a problem with the device’s input or cord requiring a replacement. Deactivate HDMI CEC on your TV for some time to rule out any possibility.

Update Firmware

Any device that has firmware requires updates to fix existing issues and adding new features to it. Like other OEMs, Vizio also releases upgrades for its firmware. Therefore, you need to check your Vizio TV for a firmware upgrade and install it immediately to fix issues like Vizio TV turns off by itself. Follow the steps below to upgrade your Vizio TV. 

How to upgrade Vizio TV firmware:

  1. Press the Menu button on your Vizio TV remote
  2. Go to the System > Check for Updates
  3. If an update is available, confirm to install it

If a firmware upgrade also fails to fix the Vizio TV keeps turning off issue, you should check out the method listed below. 

Disable Auto-Off Feature

Vizio TVs come with an ‘Auto-Off’ feature that automatically turns the TV off when a preset time has passed. However, it should only happen while the TV is idle. Thus that might explain why your Vizio TV turns off abruptly. Follow the steps below to disable the feature.

How to turn off Auto-Off on Vizio TV:

  1. Press the Menu button on the Vizio TV remote 
  2. Go to Timers > Auto Power Off 
  3. Turn Off the option 

If even after turning off the Auto-off feature, your Vizio TV keeps turning off, you must continue to the following method. 

Plug TV Directly Into The Outlet

Another possibility is that you have a power spike. Many electronics connected to the same power source (power board/strip) might be causing the power issue with your Vizio TV. To fix the problem, you must plug your Vizio TV directly into a power socket. 

If your Vizio TV keeps turning off after directly plugging the power cord, then head to the next method. 

Prevent Overheating

Your Vizio may also switch itself off if it detects overheating. The sensors that detect overheating could be malfunctioning, in which case you will need to replace them. You must contact Vizio customer support to get a professional technician to replace the sensors as this process will require taking out the TV’s motherboard. 

Assuming it’s an overheating issue, lowering the processing power and cooling down the TV should temporarily fix the issue for you. Try cooling down your Vizio TV by fanning the back panel and lowering the brightness, sharpness, contrast, and color to reduce the device’s processing power and heat accumulation.

Reset To Factory Settings

If all fails, you can try to factory reset your Vizio TV. By doing a factory reset, you will erase all the saved settings and preferences on your TV and bring it back to the state when you first bought it. Follow the instructions below to easily factory reset the TV. 

How to factory reset Vizio TV:

  1. Press the Menu button on your Vizio TV remote
  2. Go to System and press OK
  3. Select Reset & Admin and press OK
  4. Choose Reset TV to Factory Defaults and press OK
  5. If you don’t have a custom parental code, then enter 0 0 0 0 when the password pop-up shows on the screen
  6. Choose Reset and press OK
  7. Now, wait for your Vizio TV to turn off
  8. Your Vizio TV should power on in a minute

Contact Vizio Support

If every troubleshooting method renders ineffective, you must contact Vizio customer support. They can walk you through some other troubleshooting methods specific to your TV model. 

VIZIO TV Turns Off by Itself: Why Does This Keep Happening

Why does your VIZIO TV turn off by itself, and why does this issue keep happening? We give you a few pointers to know why this issue happens and how you can find the root cause behind it. 

    • A glitch in your power supply could cause the issue; perhaps a power surge results in your Vizio TV shutting off. You should unplug it from the power outlet and disconnect all the cords. If connected to a power strip, try plugging the TV directly into the wall outlet. 
    • Another cause could be the HDMI cable connected to the TV, or the HDMI port itself is damaged. In case of a faulty cable, replace it quickly. If the HDMI port is damaged, you should leave that port idle and ensure no cable is connected. 
    • Sometimes the Vizio TV turns off by itself because of a defective remote. You must clean your Vizio TV remote thoroughly and replace the batteries on it. If cleaning does not help, remove batteries from it and control the TV with physical buttons on the back and side panel. 

    VIZIO TV Keeps Turning On and Off

    Vizio TVs that switch themselves on/off repeatedly may have a different set of problems. One apparent reason is that the power cord is loose and should be reattached.  

    As an alternative, try some of the other methods listed below to stop your Vizio TV keeps turning off. 

    Check Other Remotes 

    Often infrared sensors on one remote could end up interfering with another remote. This usually happens when you have more than one remote with comparable programming. You can install the SmartCast app to control your Vizio TV from your phone instead of the physical remote to troubleshoot this issue successfully.

    Deactivate CEC Function

    If your TV is equipped with a CEC feature, you may adjust the volume and power using another device’s remote control. There are occasions when things might go wrong, causing your device to send signals to your TV telling it to turn on or off. By deactivating the CEC function, you can stop this interaction. 

    How to disable CEC function on Vizio TV

    1. Press Menu on your Vizio remote
    2. Go to System > CES
    3. Select Off to disable the feature 

    Turn On Eco Mode

    When Eco Mode is enabled, all unwanted connectivity with other devices is immediately disabled to save power. This also includes the possibility of your TV receiving mixed messages from somebody else’s SmartCast app. You can stop all the external communications by enabling the Eco Mode. Follow the steps below. 

    How to turn on Eco mode on Vizio TV:

    1. Press Menu on your Vizio remote
    2. Go to System > Power Mode
    3. Select Eco Mode > On

    Activate QuickStart Mode

    Eco Mode may not work for some users, although activating QuickStart Mode has been known to fix the problem in some cases. You can enable the QuickStart mode by following the instructions below.

    How to turn on QuickStart mode on Vizio TV:

    1. Press Menu on your Vizio remote

    VIZIO TV Won’t Turn Off

    If your Vizio TV won’t turn off (also described as the issue wherein the screen goes black with a flicker of the backlight), then you will need to change the input and drain the internal memory to fix the issue. 

    Change the TV Input

    In some cases, Vizio TV won’t turn off if it is set to a particular input. You can turn off the TV by changing the input or switching to the TV’s main menu. 

    Some CEC features may also contribute to the problem. Disable the CEC functionality by going to Menu > System > CEC > Off. Almost certainly, the input device provides conflicting signals to the TV, which causes it to misinterpret the user’s orders to switch off the TV.

    Discharge the TV’s Internal Memory

    Sometimes the internal memory on your Vizio TV gets overloaded and must be cleared. You can discharge the internal memory by holding the power button for 30 seconds and leaving your Vizio TV unplugged from the power source. 

    VIZIO TV Won’t Turn Off With Remote

    If your Vizio TV is not responding to the remote and won’t turn off with the remote, then you must try the following fixes. 

    Check The Batteries 

    Check your Vizio remote’s batteries and test to see if the batteries are working. If not, replace them immediately, and then try turning on your Vizio TV. Also, make sure that the IR signals between your Vizio TV and remote are unobstructed. 

    Reset the Remote

    You can also reset the Vizio remote to restore the power off function. Remove the batteries from your Vizio remote control and push each button multiple times. Doing this will drain the remote’s remaining charge and any faulty components that were causing issues.
