If you are like me who enjoys watching their favorite shows, then I understand the feeling of getting frustrated as your Vizio TV keeps turning on and off. 

Here you are all pumped up for the show and the next minute, the screen blacks out only to come back on a few seconds later. 

Such weird behaviors not only ruin the fun part of your TV, but can also lead one to believe that their TV might be breaking down. 

Fortunately, in most of these cases, it is not a case of dramatic hardware malfunction. 

To be more specific, there are many reasons for this odd behavior, and if you know what to look out for, you can fix the situation quickly and on your own.

So in this rather extensive article, we will take you through everything in regards to the repeated turning on and off behavior exhibited by a Vizio TV and how you can fix the issue. 

We will address everything from basic issues of power interruption to more nuanced aspects of software bugs and problems with the hardware. 

We will examine potential reasons why an issue is considered so, provide instructions on how this issue is treated, and supplement with personal narratives and tips, relevant to actual practice.

Understanding the Problem: Why Does a Vizio TV Turn On and Off Repeatedly?

However, before going to the troubleshooting guide, let us first consider the reasons as to why there is a problem with your Vizio TV. 

 

Slideshows are frequently seen on Vizio TV. There are a few frequent issues that can cause a Vizio TV to switch on and off on its own. 

 

It is very vital that the problem is properly diagnosed in order to facilitate an effective remedy.

Power Supply Issues

 

This is one of the reasons why Vizio TV will often turn on and off on its own and it is related to the power supply. 

This may be due to a loose connection, short in the wiring within a wall power outlet, or a defect in the power strip outlet.

If the power supply is disrupted on a Vizio TV, the TV may try to turn on but gives up because of loss of stable connection. 

In this manner, the device starts rebooting itself in order to restore the normal link state and normalize energy supply to the television.

Faulty Remote Control or Buttons

 

In other instances, a problem that is as trivial as a power button getting stuck may be the cause of your television continuously turning itself on and off. 

 

In this case, the remote is constantly sending some unwarranted command to the TV which makes it keep rebooting Aladdin’s lamp. 

 

The more plausible explanation is a dead or failing battery inside the remote. 

 

In the same way, the same situation can occur when the physical buttons of the television are damaged or stuck which will make the television power on and off without any external signal.

Outdated Firmware or Software Glitches

 

An extreme case where Vizio TVs cease to work can be caused by old software or firmware. 

 

In a scenario where the software within the TV does not function appropriately, the television set may end up in a state where it restarts itself frequently, or does not switch on at all. 

 

This could happen due to improper installation of an update or a bug in the system.

 

Additionally, other issues may be due to the fact that the television goes through a restart and then comes back to its own position. 

 

Maintains this cycle as it is trying to consecutively update the TV software but this never gets done fully.

Overheating

 

Cooling ventilation is built into televisions nowadays. Even so, some designs still have the situation of fatably poor ventilation causing overheating of the TV. 

 

In an event where your Vizio television overheats, in most situations the internal components are damaged, therefore.

Such a television would switch itself off. Such overheating may occur because of placement or lack of sufficient ventilation.

Internal Component Failures

 

Among the factors why this repetitive switching of the device on and off occurs include; failures of the internal hardware which include the power supply board, mainboard and capacitors. 

 

Such components may lead to TV operating erratically, and serious repairs are then needed. 

 

Actions involving replacement of defective parts in this case are possibly standard responses as well as outright replacement of the TV set.

Connected Devices or HDMI Conflicts

 

You might have connected some devices like soundbars, DVD players, or game consoles to your Vizio TV which could be the source of the problem. 

 

It may even be due to a bad HDMI cable or a faulty HDMI port sending wrong signals to the television, causing the television to turn off and back on again.

How to Fix a Vizio TV That Keeps Turning On and Off

 

Now that we have pointed out some of the fundamental problems that could cause the issue, fingers crossed this isn’t the end of the world for you. 

 

Let us speak about how you can resolve this. I’ll cover each probable explanation in full length, and I also have some stories for you from the people who suffered quite similar troubles and who got help.

Fix #1: Power Supply Issues

 

If the Vizio TV is switching on and off frequently, it could be because of power supply issues, and initially, you should check the wires and see if they have been put in snugly.

What You Can Do:

Check the Power Cord:  

Look into the power cord attached to your Vizio TV and confirm that it is not loose on both the TV and Wall power socket. 

 

If you can see that the cord may be broken or worn out, you will need to buy a new one.

Test with a Different Outlet:

Personal preferences have no power here as the TV’s plugs must be connected to a properly working electric outlet. 

 

In cases where the TV suddenly loses power, it is helpful to check whether the screen shows no signs of life or, if it is a dark color, make sure that the cord has not been disconnected from the outlet.

Use a Surge Protector:

If your TV has been connected to a power strip, ensure that it is installed with a surge protector, and not just a simple power strip. 

 

A surge protector should be used because it will stabilize the power supply and avoid any electrical surge issues.

Try a Power Cycle: 

Turn off the TV from the wall outlet and wait about 30 seconds before plugging it back in. 

 

This procedure is beneficial in many instances and restores the internal components of the TV which has been affected by a minor glitch.

Real-Life Example:

 

There is one friend of mine who had this specific issue; her Vizio TV would turn on and off all the time and she assumed that the television was defective. 

 

After trying a number of the outlets she saw that her power strip was unstable and was not supplying power. After she installed the surge protector, the issue was sorted.

Fix #2: Remote Control or Button Problems

 

If the TV or remote has a defective power button, it would be possible for the TV to turn on and shut off on its own. 

 

This can occur when a button remains depressed, or when the batteries in the remote are weak.

What You Can Do:

Remove the Batteries from the Remote: 

Disengage the batteries that relay the signal from the remote control and explore if the fault still occurs. 

If the TV does not switch on and off after doing this, the likely cause is the remote control.

Check for Stuck Buttons:

Look for any buttons that may be stuck or protruding on the TV as well as on the Remote Control. 

 

If you find some of the buttons pressed in and not able to move, try to loosen them up a bit and check whether the issue is resolved.

Test with a Different Remote:

Check any other Vizio remote you may have by using it on your TV. See if still the behavior remains the same with the new remote. 

 

If the TV works normally with the new remote, then the very old one could be the one to blame.

Personal Story:

 

I once owned a Vizio TV that had this nasty habit of turning itself on and off without even moments of intervals. 

 

At some point, I thought it was an issue of software malfunction but after taking out the dv3 batteries of the remote it continued. 

 

As it turned out after a while, one of the dials on the remote which had been pressed down was the cause of the continual hiccups.

Fix #3: Update the Firmware or Reset the TV

 

At times, the folly is with the TV itself where such repetitive reboots may be attributed to unupgraded firmware or faults in its software. 

 

But the solution to this problem is just straightforward which involves resetting the TV or updating the software.

What You Can Do:

Check for Software Updates: 

Open the settings on your Vizio TV and look for available firmware updates for your Vizio TV. If there is any update, check if that resolves the issue after you install the update.

Factory Reset the TV: 

If you have updated the firmware but the problem is still there, then perhaps it is worth performing a factory reset. 

All custom settings and data on the TV will be removed, but it may help in resolving deeper software hydras that are causing the power cycling problem to persist.

On the remote control press Menu, then choose Settings > System > Reset & Admin > Reset TV to Factory Settings.

Clear Cache: 

Sometimes, the TV cache needs to be cleared to fix problems with the software. 

 

This option can also be accessed through the menu Settings > System > Reset & Admin.

Personal Experience:

 

A coworker of mine was in so much trouble with his Vizio TV. The Vizio kept turning On and off intermittently after a firmware upgrade. Factory Reset restoration practices. 

 

She had the problem resolved. This approach worked as the reset resolved the corrupted system files that could potentially cause the restart loop.

Fix #4: Check for Overheating

 

Overheating is probably one of the causes of every electronic device’s issue, and your Vizio TV is not an exception. 

 

In case some internal units are overheating too much, the system has to self-protect and may turn itself off automatically.

What You Can Do:

Ensure Proper Ventilation: 

Ensure that the TV is not installed too close to walls or other structures that might restrict airflow. 

 

The vents located on the back surface of the TV require sufficient clearance to permit free air movement.

Use a Cooling Fan: 

In case the TV is placed in a warmer spot, placing a cooling fan towards. The TV area will hinder it from getting overcooked.

Turn the TV Off and Let It Cool: 

For those who feel that their TV may have been subjected to excess energy usage. They can turn the TV off.

 

Leave the TV to cool down for 30 minutes to one hour before turning the energy source again.

Fix #5: Inspect External Devices or HDMI Connections

 

In many instances, cables, external devices such as game consoles, sound bars etc. DVD players, or a disconnected HDMI lead can be the cause of the problems with your Vizio TV.

What You Can Do:

Disconnect All External Devices:  

Unplug all external devices, check if the TV does not go off and on. When the problem disappears reconnect devices one by one to see which one is the problem.

Check HDMI Cables:  

Look at all the HDMI plugs joined to the TV. If any are worn it is time to replace it with a new cable and check once again if the problem has gone away.

Try a Different HDMI Port: 

For those with multiple HDMI ports, try using a different port to confirm. Whether the problem still exists in the device connected to the TV.
