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.
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.
Vizio TV Won’t Turn Off
If you’re having difficulty turning off your Vizio TV, it could be due to various factors such as a software malfunction, a defective remote control, or a damaged power button. One potential solution is to reset the TV by unplugging it for a few minutes and then plugging it back in. Check the batteries in the remote control and replace them if necessary. If the power button is damaged, try using the remote control to turn off the TV. If these steps don’t work, it’s best to contact Vizio customer support for further assistance. They can provide additional troubleshooting steps or recommend a repair if needed.
Here are some common causes and troubleshooting steps you can try:
- Remote Control Issues:
- Check the batteries in the remote control and replace them if they are weak or dead.
- Make sure there are no obstructions between the remote and the TV, and that you are aiming it directly at the TV’s infrared sensor.
- TV Software Glitch:
- Try performing a soft reset on your TV by unplugging it from the power source for about 1-2 minutes, then plug it back in and attempt to turn it off again.
- Power Button or Sensor Problems:
- If you’re using the physical power button on the TV, ensure it is not stuck or damaged.
- Check if the TV’s infrared sensor is blocked or obstructed. Remove any dust or debris that might be covering it.
- HDMI CEC or ARC Issues:
- If your TV is connected to other devices through HDMI, sometimes issues with HDMI CEC (Consumer Electronics Control) or ARC (Audio Return Channel) can cause problems with turning off the TV. Try disconnecting HDMI cables from the TV to see if the issue persists.
- Firmware Update Needed:
- Check if there are any available firmware updates for your Vizio TV. Updating the firmware might resolve the issue if it’s caused by a software bug.
- Power Supply Problems:
- Issues with the TV’s power supply can prevent it from turning off. In this case, it’s best to contact Vizio customer support or a qualified technician for assistance.
- Faulty Mainboard or Logic Board:
- If there’s a problem with the mainboard or logic board, it can lead to issues with powering off the TV. Professional diagnosis and repair are recommended in this situation.
- Power Button Control Mode:
- Some Vizio TVs have an option to enable or disable power on/off control from the remote. Check your TV’s settings to ensure this feature is enabled.
Vizio TV Keeps Turning On and Off
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.

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.
