Vizio Tv Turns Off and Back on by Itself

The affordable Vizio TV is great until it won't stay on or won't turn off. If you have experienced this problem yourself, there are quite a few reasons why it could be happening. This article aims to outline each possible issue with your TV and how your can fix it.

A Vizio TV will turn off if 'Auto Off' is enabled, there is a power surge, the TV overheats, 'CEC' is enabled, the TV cable is loose, another device is interfering or the main board is broken. If it won't turn off, it is likely the input device, overloaded internal memory or a malfunctioning remote.

As you can see, there are a range of issues that might be causing your problem. I will explain each of these in detail below. You can also find general troubleshooting tips that will help with any electronic device.

Vizio TV Keeps Turning Off / Shutting Off Randomly

If your Vizio TV keeps turning off randomly, you can try the general troubleshooting methods below. These are standard across most electronic devices, but are very effective with most problems.

Hard Reset the TV

A hard reset will remember all your personal preferences, but will often fix unknown issues with your TV. This is something worth trying every time you have an issue because it is simple and effective.

Step 1: Turn off the TV (if you can) and all devices.

Step 2: Unplug the TV from the wall outlet.

Step 3: Hold the power button on the back of the TV for 30 seconds.

Step 4: Leave the TV unplugged for a further 10 minutes.

Step 5: Plug the TV back in and turn it on.

Reset to Factory Settings

A TV that has been reset to its factory settings will revert to its original state, like when you first brought it home. This will erase any saved preferences and downloaded content, so only do this is you are out of options.

Step 1: Press the 'Menu' button on the remote.

Step 2: Navigate to System > Reset & Admin.

Step 3: Select 'Reset TV to Factory Defaults'.

Step 4: Enter your passcode or the default passcode, '0000'.

Step 5: Select 'Reset' and confirm.

Step 6: Wait for the TV to turn off and then on again.

Update the Firmware

It is not uncommon for TVs to develop firmware bugs with updates. Vizio will then release another update to fix the previous bug. If this is the case, make sure your firmware is up to date. The TV should automatically update, but you can manually update it using the method below.

Step 1: Press the 'Menu' button on the remote.

Step 2: Navigate to System > Check for Updates.

Step 3: Confirm you want to perform the update if one is available.

Disable 'Auto Power Off' Feature

Vizio TVs have an 'Auto-Off' feature that will turn the TV off after a specified amount of time. This should only occur when the TV is inactive, but it could explain why your TV is turning off unexpectedly. You can disable this feature by following the pathway below.

Menu > Timers > Auto Power Off > Off

Plug into Wall Directly

You may also be experiencing a power surge. This occurs when too many devices are connected to the same power source, using a power board/strip. If this is the case, it should be resolved by plugging the TV directly into a wall outlet.

Prevent Overheating

The TV will also turn off if it thinks it is overheating. If this is not the case, it may be that the sensors are broken and therefore need to be replaced. This involves replacing the mother board within the TV, or organising a technician to come and look at the TV.

If it is an overheating issue, you should find that reducing the processing power and cooling the TV down will help the problem. You can start by directing a fan at the back of your TV (the hottest part). You can also reduce the processing power, and therefore reduce the amount of heat generated, by reducing the TVs brightness, sharpness, contrast and colour.

If your Vizio TV continually turns off and on again, it may be a different problem. The simplest explanation would be a loose power cord, which should be fixed by inserting it all the way. This problem would continually connect and disconnect the power source from the TV.

Below are some other possibilities, but if they do not work, you should try some of the general troubleshooting methods from above.

Be Mindful of Other Remote Controls

Sometimes it may be that there is another remote control interfering with your infrared sensor. This mainly occurs with other Vizio remotes with similar programming. If this is the case, you can try using the SmartCast phone app, which allows you to control the TV with your phone.

Disable CEC Function

The CEC function allows you to control the volume and power to your TV using the remote of another device. Sometimes this can malfunction and your device can send 'Power On' or 'Power Off' messages to your TV. You can disconnect this communication by disabling the CEC feature with the steps below.

Menu > System > CEC > Off

Turn Eco Mode On

Eco Mode will automatically disable unnecessary communication with other devices to save power. This includes someone else's SmartCast app sending mixed messaged to your TV. You can Turn Eco Mode on using the following method.

Menu > System > Power Mode > Eco Mode

Enable QuickStart Mode

If Eco Mode does not work, some people have also found that enabling QuickStart Mode fixes this issue. You can turn this on via the pathway below.

Menu > System > Power Mode > QuickStart Mode

Vizio TV Just Shut Off and Won't Come Back On

There is not much else you can do for a TV that won't turn on, other than doing a hard reset. You can find the steps for this at the beginning of this article.

If this doesn't work, it is most likely that the mother board has been damaged or gotten to the end of its life. If this is the case, you can either try to replace the mother board, or look at replacing the TV.

Vizio TV Won't Turn Off

Some people have had the opposite issue, where their Vizio TV will not turn off. This is often described as the screen going dark, but a backlight remaining on. Below are some fixes that have worked for this specific issue.

Change the TV Input

Sometimes the TV will not turn off when it is set to a specific input. If you switch the input, or return to the TV main menu, this may allow you to turn the TV off.

This may be a problem with the CEC features again, as mentioned above. If this is the case, you could try disabling this feature. It is most likely that the input device is sending mixed signals to the TV and interfering with the user's commands to turn the TV off.

Discharge the TV's Internal Memory

You can also perform a hard reset. Sometimes the internal memory becomes overloaded and needs to be discharged. When you hold the power button for 30 seconds and keep the TV unplugged, you are allowing the memory to be discharged.

Vizio TV Won't Turn Off With Remote

If it is just the remote that is not turning off your TV, it may be an issue with the remote itself. You should first replace the batteries in the remote to see if that is the issue. However, this would cause all buttons on the remote to fail.

You should also make sure nothing is blocking the infrared signal between the remote and the TV. If the pathway is clear and your remote has new batteries, try resetting the remote.

Reset the Remote

You can reset your Vizio remote by removing the batteries and pressing each button several times. This will drain the residual charge from the remote, clearing any malfunctioning components. It will also help dislodge any debris that may be stuck under the power button.

If none of these methods work, try some of the general troubleshooting methods mentioned at the beginning of this article.

When your Vizio won't turn off but you can still see a backlight, it may be the device input or an overload of the TVs internal memory. You can find fixes for these issues above.

This has particularly been an issue with cable/set-top boxes. When you turn the TV off, the screen will go blank but not fully off, and then come back on again as soon as the cable remote registers you are using it.
