Vizio TV Turns ON then OFF by Itself – Causes?
As a Vizio TV user, I understand the frustration of having your TV OFF by itself. Outdated firmware, overheating, interference from other devices, and faulty TV components are all plausible reasons for this problem.
- Ensure you have your TV’s most recent firmware update to avoid any software-related problems.
- It’s essential to ensure enough airflow and ventilation for your TV to function correctly and avoid having it switch off by itself due to overheating.
- Other household electronics, such as remote controls, might disrupt your TV’s signal and turn itself off.
With that said, let’s continue toward possible solutions!
1. Power Cycle your Vizio TV
If your Vizio TV keeps randomly going on and off, a power cycle should be your first line of defense.
The term “power cycling” refers to shutting off and disconnecting the TV for many minutes before restarting it. It may fix minor issues in the TV’s internal circuitry by resetting the device.
To power cycle your Vizio TV, follow these steps:
- Turn OFF your TV.
- Unplug it from the power source.
- Find the power button on your Vizio TV and press it for 15-20 seconds.
- Release the power button and keep the TV unplugged for another 1-2 minutes.
- After waiting some time, plug your TV back into the power outlet.
- Turn ON your TV.
Now check if the issue has been resolved or not. If the issue continues, consider the alternative solutions below.
2. Disable the Auto Power Off feature on your Vizio TV
As a Vizio TV user experiencing this issue, I found that disabling the Auto-Off feature on your TV is valuable.
Here’s how you can do it:
- Press the “Menu” button on your TV’s remote.
- Go to “Settings.”
- Go to “Timers.”
- Scroll to “Auto Power Off” and press the right arrow button to disable it.
It should stop your Vizio TV from turning off by itself.
3. Ensure that your TV’s Remote is working Correctly
A malfunctioned remote control might be to blame for your Vizio TV’s random on/off behavior.
Follow these steps to test the functionality of your TV’s remote:
- Look for rust or other damage in the remote’s battery compartment. If any batteries are dead, please change them out.
- Place the remote sensor in front of the TV and press any button. If the remote is functioning, a red light should illuminate the front of the TV. If the indicator LED doesn’t glow, it means that the remote is not working, and you must replace it immediately.
- If the TV keeps turning ON and OFF, even if the remote works, consider resetting the TV remote. Take out the batteries and press the power button for a few seconds. Put the batteries back inside, and then try using the remote again.
By ensuring that your TV’s remote is working correctly, you may be able to fix the issue of your Vizio TV turning on and off by itself.
4. Disable the HDMI-CEC Function
With HDMI-CEC, electronics may communicate and exchange data with one another.
Using HDMI CEC, you can control your TV with your DVD player remote. You only need a remote to manage multiple devices, adjust the volume, or put something on mute.
When casting to a CEC-enabled TV, whether viewing a local channel, using a cable, or putting a USB device into the TV, the source input will switch to the HDMI port where the casting dongle is connected.
The HDMI CEC function enables automatic device communication, allowing a DVD player to turn on a TV and switch to the correct input. However, it can also cause issues, such as the Vizio TV turning on and off due to conflicting CEC signals.
Since the development of Smart Home technologies, most Smart TVs, including your Vizio TV, have this HDMI-CEC capability activated. So it needs some investigation!
- Press the “Menu” button on your Vizio remote.
- Select “System.”
- From there, select “CEC” and ensure that it is disabled.
By disabling this feature, you can eliminate this possibility as a cause for the problem. It is also possible to disable HDMI-CEC on other devices, such as cable boxes or DVD players, which may be causing interference.
5. Remove the Surge Protector and Plug your TV Directly into the Power Outlet
A loose power connection may cause an unintentional on/off cycle in a Vizio TV.
It is conceivable that using a power strip or surge protector is to blame for the electricity problems you’re experiencing.
One possible solution is to unplug the surge protector and reconnect the TV to the wall socket directly. It removes the risk of a loose connection and guarantees a constant power supply to the TV.
- First, turn OFF your TV and ensure the surge protector is disconnected.
- After that, reconnect the TV’s power cord to an electrical socket and power it back on.
If the television continues to operate normally after disconnecting it from the surge protector, then the protector is likely at fault. If the TV keeps cycling on and off, you may need to consider alternative options.
6. Disable all of the Timers on your TV
As I continued troubleshooting the issue, I realized the sleep timer might cause it. To disable all timers on your TV, follow these steps:
- Go to Menu > Settings > Timers.
- From there, turn OFF all the timers.
It would prevent the TV from shutting off automatically after a specific time period.
7. Fix the Loose TV Cables to Ensure Your TV is Getting Enough Power
Another possible solution is to check the wires connecting it to the power outlet. Your television might lose power and turn off if a cable dangles loosely.
- Turn off the TV and remove all the cords from the back before attempting any repairs.
- If you find any damage or a loose connection, check each cord and reattach it correctly.
- Ensure the cable is not pulled or twisted and plugged into the correct slot.
- Plug in the power cord properly and switch on the TV.
Check if the issue is resolved or not. This solution may fix the problem in most cases.
8. Update Firmware of your Vizio TV
Using an outdated OS on your Vizio TV might cause several problems. The good news is that you may easily fix it by updating your Vizio TV firmware to the most recent version.
However, if you turn off automatic updates, your Vizio TV’s operating system will quickly become outdated and need manual upgrading.
- Make sure your Vizio TV is powered on and connected to the Internet.
- Go to the “Menu.”
- Select “System.”
- Select the option to “Check for Updates.”
- A confirmation window will appear, asking you to confirm your choice; select “Yes.”
That’s all! Your TV will restart once after updating the firmware.

Updating your TV’s firmware might reduce the likelihood of it crashing unexpectedly. In addition to making your TV run better, it may provide you access to brand-new functions as well.
9. Fix the Overheating of your TV
Overheating is a possible cause of your Vizio TV turning on and off by itself. If your TV becomes too hot, it will turn off automatically to protect its internal components from melting.
Take the following precautions to keep your TV safe from overheating:
- Ensure nothing is blocking your TV’s air vents to prevent it from overheating.
- The air vents are located at the back of the TV and aid in circulating air to cool down the TV.
- Place your TV in a location with plenty of air circulation and protection from the sun.
- Turning down the TV’s brightness and contrast may potentially help with the overheating problem.
Doing so will increase the TV’s efficiency and stop it from powering off unexpectedly.
10. Ensure that other devices are not Interfering with your TV
First, ensure that other devices are not interfering with your Vizio TV and that all devices (including other Vizio TVs) are powered off.
Try moving other devices away from the TV or disabling CEC mode on all of the connected devices. Additionally, check if any other remotes in the house might accidentally be turning the TV ON or OFF, and ensure that only the Vizio TV remote is being used.
Another option is to enable the HDMI-CEC feature on your Vizio TV, which allows it to control connected devices without interference from any of them.
11. Enable the Eco Mode or Quick Start Mode
Enabling Eco Mode or Quick Start Mode on your Vizio TV may be one of the best solutions. Quick Start Mode lets your TV power up fast, while the Eco Mode setting uses less than 0 .5W of power.

Here’s what you need to do to activate these settings:
- Press the “Menu” button on your TV remote.
- Go to “Settings” and select “System.”
- Go to “Power Mode.”
- Scroll down to Eco Mode or Quick Start Mode.
- Enable both of these modes.
Doing so will help your TV conserve energy and makes it more efficient. It may also prevent the issue from happening again in the future.
12. Factory Reset your Vizio TV
Doing a hard reset will delete all your data and settings, so create a backup copy beforehand.
To perform a factory reset, follow these simple steps:
- Power ON your TV.
- Go to the “Menu.”
- Select “System” and press “OK.”
- Choose “Reset & Admin” and press “OK.”
- Select “Reset TV to Factory Settings” and press “OK.”
- Enter the parental control PIN code for your TV, if applicable.
- Select “Reset” and press “OK.”
Your Vizio TV will now turn OFF and back ON once again to complete the reset process.
