Some Vizio TVs eventually run into a common issue: they turn on by themselves.
There are countless cases of Vizio TV owners claiming to have experienced this issue, with some claiming it’s been a problem for years!
Fortunately, there is a quick fix that should fix about 80% of Vizio TVs are turning on by themselves.
How To Fix A Vizio TV That Turns On By Itself
If your Vizio TV is turning on by itself, there’s a good chance it’s because you have HDMI-CEC turned on. Since certain HDMI devices (like a Firestick or Apple TV) turn on your TV automatically when they turn on, this can cause issues. To turn off HDMI-CEC, go to Settings > System > CEC > Off which should fix your TV!
HDMI Consumer Electronics Control (Also known as HDMI-CEC), is a feature most HDMI televisions have that helps your electronic devices work better together.
It gives your HDMI devices partial control over your television so they can work as intended.
EXAMPLE: Your cable remote control is able to power your television and adjust the volume without needing the TVs remote control.
Most Vizio TVs have this option enabled by default so follow these instructions to turn it off and see if it fixes your TV turning on and off.
To turn HDMI-CEC off, click Settings > System > CEC > Off.
When you disable HDMI-CEC, you will need to use your Vizio remote to control the television’s power, sound, input, and more moving forward.
Now, wait a few minutes and see if this fixes your problem. If not, try the rest of our troubleshooting tips.
Disable Economy Mode
Another feature that comes enabled with your Vizio TV is Economy Mode. As the name suggests, it helps your television save power whenever possible.
Unfortunately, this can cause issues with your television at times.
To disable economy mode on your Vizio TV, follow these steps:
- Click Settings.
- Press System, then scroll to Eco (or Power) Mode.
- Check the “Eco (or Power) Mode settings.”
- If it’s on, switch it to “Quick Start.”
Soft reset your Vizio TV
If those settings didn’t fix the issue, the next step is to try power cycling your Vizio TV.
Disconnect your TV from the wall and wait 60 seconds. After a minute, plug your TV back into the outlet. This will give your Vizio TV a soft reset, and it should fix any lingering issues your television is having.
NOTE: This is more effective than just turning the TV on and off.
Remove batteries from remote control
If unplugging and re-plugging the television didn’t resolve the issue, remove the batteries from the remote control.
Make sure that both batteries are fully removed from the remote.
With the batteries out, press and hold the remote control’s power button for 15 seconds.
After 15 seconds, replace the batteries in the remote and attempt to switch on the television. It should reactivate.
Suppose either of the two techniques above resolves your Vizio TV’s power issue, but the problem persists a few days or weeks later. In that case, you should reset your TV to factory settings for a more permanent solution.
Update your Vizio TVs software
If you haven’t updated the software on your Vizio Smart TV, the sound issue may be caused due to this.
That’s one of the many reasons to make sure you’re using the latest software update.
When your Vizio TV is connected to the internet, it should automatically scan and install software updates when they release.
But if that isn’t the case, you’ll want to update your TVs software manually:
- Press the Home button on your remote control.
- Click the Settings icon.
- Select System.
- Choose Check for Updates from the menu.
NOTE: While you’re in this menu, you can check for updates manually.
Make sure the power supply is secure
Unplugging the power cord from the back of the TV is another quick way to fix your power problem.
You should unplug this for about a minute, and then plug it back in.
Ensure the connection is tight when you plug the power cord back in! You don’t want this to be loose. Having a tight connection is important to make sure the TV gets consistent, reliable power.
After plugging it back in, turn on the TV by pressing the power button on the TV — do not use the remote.
Remove sleep timers
Vizio TVs use sleep timers to help conserve energy and turn your television off after a specific amount of time.
This makes it useful if you’re going to sleep and don’t want your television on wasting electric throughout the night!
While this may not seem relevant, it could cause issues as it has to do with the televisions power.
To disable your sleep timer, use the following instructions:
Select Settings > Timers > OK > Sleep Timer > Off.
NOTE: You can also turn “Auto Power Off” as well.
Factory reset your Vizio TV
If you are still having issues after trying the solutions above, you should factory reset the TV before contacting Vizio.
NOTE: This will remove all the data, accounts, settings, and applications from your device.
With a remote
- Open the Menu by clicking the “Menu” button.
- Click the “System” settings in the menu.
- Find “Reset & Admin” then click “Reset TV to Factory Defaults.”
You may be asked for a code when doing this; if so, the default code is four zeros, or 0000.
Without a remote
- Find the power button on your TV – this may be on the left, right, or bottom of your device depending on the model.
- Press and hold the volume down and source buttons simultaneously while the TV is on.
- After a few seconds, your TV will ask you to click and hold the input button.
- Make sure you hold the input button for at least 10 seconds.
This will revert your Vizio TV to its settings when you first bought it, fixing any potential firmware issues.
Contact Vizio support (or another professional)
Still no luck? Try contacting Vizio customer support.
They may offer more help for your particular model, or even have a recommendation not listed in this post, such as replacing internal components like your power supply.
If the issue can be resolved over the phone or by sending your TV in for service, the Vizio customer service staff may be able to assist you.
Check your Vizio warranty
If all else fails, you should check your Vizio warranty and see what comes from it.
You’ll have to provide information on what’s happening with your TV, and they’ll determine the next steps.
Here’s what could come from your warranty:
- Nothing (warranty doesn’t cover the issue)
- Repair (send the TV in to get fixed or they may come right to your house to fix it)
- Replacement (you may receive a new TV depending on what happened)
It’s worth a shot if you’ve tried everything else on this list with no solution. Hope this helped!
