When your Vizio TV keeps turning off, the best thing to do is conduct a power cycle and discharge its residual electrical energy. After all, it’s a common cause of various system-related malfunctions and errors on Vizio TVs.

The power cycle is a simple procedure that anyone can execute without issues, making it an ideal troubleshooting method to try first. With this action, your Vizio TV can reset and refresh its system memory, allowing it to straighten errors out. 

Once you’ve discharged your Vizio TV’s residual electrical energy, plug it back into the power outlet to reintroduce electricity to its components. You should be able to prevent your Vizio TV from turning off automatically, improving overall performance.

Step 1: Turn off the Vizio TV and unplug it from the wall outlet.


Note: You can unplug the power cable without turning the Vizio TV off to force it to reboot.
Step 2: Hold its physical power button for 60 seconds to discharge all residual electrical energy from the Vizio TV.


Note: The power button location varies between Vizio TV models. Some Vizio TVs have it at the back panel, while others have it underneath the front bezel.
Step 3: Plug in the power cable to power your Vizio TV.


Note: Press its power button if the Vizio TV doesn’t boot up automatically.
Step 4: Allow the Vizio TV to reboot and check whether or not it will keep turning off again.

The HDMI-CEC feature on your Vizio TV is also a common cause of booting issues. It’s due to external HDMI devices connected to your Vizio TV having partial control over it because of the CEC technology.

With HDMI-CEC, you can control multiple devices connected via HDMI cable using one remote control. You can use your Vizio TV remote to operate a connected streaming device, gaming console, projector, or Blu-ray disc player and vice versa.

Although incredibly convenient, this feature may cause you to accidentally turn off your Vizio TV when shutting down a connected external HDMI device. Therefore, it’s best to deactivate the HDMI-CEC feature when your Vizio TV keeps turning off.

Step 1: Press the Vizio remote control’s Menu key to open your TV’s settings menu.

Step 2: Go to System.

Step 3: Open the CEC menu.

Step 4: Click the CEC option and enable your Vizio TV’s HDMI-CEC feature.

Faulty external devices are another possible reason your Vizio TV keeps turning off during use. In most cases, turning off the HDMI-CEC feature should be enough to deal with issues caused by all external devices connected to your Vizio TV.

Unfortunately, it’s also likely for external devices to make your Vizio TV appear turned off if the input source is faulty. It can happen if the cables connected to your Vizio TV are loose or the connected external device has software/hardware issues.

As such, we recommend inspecting the connections between your Vizio TV and all its external input devices. In particular, you should check the cables and connectors for damage and ensure their connections are tight and secure.

Step 1: Use the Vizio remote control’s Power key to turn off your TV.


Note: You can also use the physical power button on your Vizio TV.
Step 2: Unplug any HDMI cable, RCA connectors, or AUX cable connecting your Vizio TV to an external device.


Note: You must look into the external devices to ensure they aren’t causing your Vizio TV to turn off. You must also replace damaged cables and connectors immediately.
Step 3: Plug the cables of your external devices into the Vizio TV. Secure all the cables to prevent loose connection issues.

Fix 4. Deactivate its Auto Power Off feature

Auto Power Off is another feature often associated with issues regarding a Vizio TV that keeps turning off. As its name suggests, Auto Power Off automatically shuts down your Vizio TV after a preselected time limit.

For example, setting your Vizio TV’s Auto Power Off feature at 30 minutes will cause it to shut down automatically after being used for that long. As such, it’s a handy feature that can work as a parental control if you want to limit a child’s watch time.

However, Auto Power Off can be annoying when binge-watching a TV series since the constant shutdowns will break your immersion. It’s advisable to keep this feature turned off to help yourself fully enjoy the watching experience on your Vizio TV.

Step 1: Press the Vizio remote control’s Menu key to open your TV’s settings menu.

Step 2: Go to Timers.

Step 3: Click Auto Power Off.

Step 4: Set it to Off to prevent the Vizio TV from shutting down automatically.

Overheating is dangerous for all electronic devices, and your Vizio TV isn’t an exception to this rule. Allowing your Vizio TV to overheat frequently can cause its components to burn and suffer irreparable damage.

When your Vizio TV keeps turning off, it may be a defensive mechanism triggered by an overheating issue. When this happens, it’s best to let your Vizio smart TV cool down before turning it back on.

You can also speed up the cooling-off process by placing your Vizio TV in front of an electric fan or a room with good ventilation to improve heat dissipation. You must only turn your Vizio TV on once it has completely cooled down.

Fix 6. Plug the Vizio TV directly into your wall outlet

More often than necessary, power-related issues can also cause your Vizio TV to keep turning off. After all, a good power supply is essential for a Vizio TV to turn on, run its apps and programs, and perform various tasks and functions.

Without a reliable power supply, your Vizio TV can’t maintain its functions, causing it to turn off automatically. Sometimes, this problem may occur if the Vizio TV is connected to a power strip instead of a wall outlet.

This power-related issue usually happens when you plug multiple devices into a power strip, which can overload the system and cause power spikes. Once power spikes, your Vizio TV might turn off from overheating or fail due to short-circuiting.

Fix 6. Plug the Vizio TV directly into your wall outlet

If you must plug in multiple devices simultaneously, ensure they’re all low-energy devices to prevent overloading your power strip. Since it’s better to be safe than sorry, not plugging multiple devices into one power strip is the best thing you can do.

Fix 7. Update its firmware

Your Vizio TV may also keep turning off power-related issues and connections due to software problems. In most cases, it results from using outdated system firmware, making it prone to bugs and errors that cause booting issues.

Every once in a while, your Vizio TV should receive a firmware update to ensure it’s working in peak condition, strengthening its system against bugs, errors, compatibility, and security issues. 

As such, you must always check for updates under the system settings menu so you can download and install the latest version.

Step 1: Press the Vizio remote control’s Menu key to open your TV’s settings menu.

Step 2: Go to System.

Step 3: Click the option to Check for Updates under the system settings menu.


Note: Ensure your Vizio TV is connected to a WiFi network so it can search the internet for any available firmware update.
Step 4: Click Yes if a confirmation prompt appears to start downloading and installing the latest Vizio TV firmware version.
Note: If your Vizio TV is running low on memory, uninstall apps or delete files beforehand to avoid installation problems.

If your Vizio TV keeps turning off even after the firmware update, it may be because of a system error due to a malware or virus infection. Thus, your only remaining option is to perform a factory reset to restore your Vizio TV’s default settings.

WARNING: Remember to retain a copy of essential files before doing a factory reset. If not, you may lose them all to the process. 

Unfortunately, you must part with your essential files and installed apps since the factory reset will delete them all. While that might be a huge downside to some, it’s a small price to ensure your Vizio TV has no nasty malware or viruses left.

Consequently, after the factory reset, you must go through your Vizio TV’s setup process. This part should be simple to perform, thanks to the easy-to-follow instructions on your Vizio TV screen.

Step 1: Press the Vizio remote control’s Menu key to open your TV’s settings menu.
