It is indeed annoying when one prepares for a good session of watching their favorite series only to realize that his Vizio won’t turn on and that the power light fades out within no time of pressing the button. 

For someone who is a TV lover cum a tech whizz, this situation is something I have faced a good number of times. 

Each one of them made me slide down the never-ending troubleshooting process where each victory always ends in a sense of wow. 

The screen is finally on! Here in this extensive article, we will explore the different causes behind the occurrence of the problem. 

Present several stories that illustrate the understaffed nature of the problem. 

Give concise and straightforward instructions on how to deal with the problem.

Identifying One’s Vizio TV Problem – A Vizio TV that does not come on, what happened to it?

Staying with the issue of trying to fix the problem, I think it is good to note that it is important in the first place to note the reasons that can make your Vizio TV not turn on.

Not only would this help you auto-diagnose the problem, but it will also help you keep clear of issues that may pop up sometime in the future. 

There is more than one such reason, the issues can be classified into six categories: 

Power Supply Issues

If a Vizio TV is unable to turn on, then it is likely that the main power supply is the defective component. 

Common issues such as this one originate from the usage of the power supply unit which in some cases may fail to work properly. 

This further prevents the unit from fully turning on because the power light goes off whenever the viewer presses the switch to turn on the device.

Problems with Remote Control

Once, the control console can be a blame. When all the batteries have been used up, or if the remote control of the television set is broken. 

Then it might not be able to transmit the command to turn on the TV.

Problems with the Hardware

Things like capacitors or internal modules such as the main board can become defective with the passage of time, and this will explain why the television set has difficulties turning on. 

The chances of this happening are very high, especially with older television sets or televisions that have been in use for years.

Problems with HDMI and Other External Devices

Sometimes problems can also emanate from some other components like gaming consoles or streaming devices which can make your television set remain off. 

If there is such a scenario where the television set is on standby mode in preparation for a particular action and due to a faulty connection doesn’t go ahead. 

The power switch will not be able to function.

Problems with the Firmware

And like any other electronic device, a television is also a machine that can have software bugs. Even a posteriori flash firmware bug may be the cause of such unresponsive behavior, so the power light dims down.

Problems with Overheating

Overheating is also another cause of why someone would experience issues when attempting to turn on a television. 

In instances where your television set has been on for a prolonged period and there’s no adequate cooling, it might have gone off automatically to protect itself.

The Psychological Impact of Technical Difficulties

To illustrate this further, let me give you a personal revelation. 

Last summer, I was just about to enjoy a movie night with my friends. We had popcorn and chilled drinks, and the living room was all arranged. 

This, however, was not the case. I pressed the power button on my Vizio and the light went on for a split second before going off. 

I almost broke down. After some seconds of hysteria and a lot of adrenaline rush, I managed to start the diagnosis. 

I learned that all I needed was to restart the machine. 

This went on to show me just how far we have come in using technology to obtain entertainment objectives, and how simple a power failure can completely throw our plans off track.

How To Troubleshoot A Vizio TV That Is Not Turning On

Moving on, having identified the probable causes, let’s now consider the step-by-step practical methods of troubleshooting that can be employed to restore the operations of the Vizio TV.

Step 1: Ensure the TV has power

Check the power cord connection

Check the connections of the power cord to make sure it is properly connected to the TV unit and wall outlet. Also, if the outlet has an on/off switch, ensure it is in the “on” position.

Change the TV’s Power Source

Try unplugging the TV and plugging it into a different outlet to see if it works. Sometimes, an outlet fails to provide power.

Voltage testing

Additionally, if a multimeter is handy, it can be used to check the voltage of the power outlet. If the outlet is still delivering voltage then you should call an electrician to fix the socket.

Step 2: Troubleshoot the power cable

Look for wear and tear on the cable

Worn or cut areas on the power cable can prevent the correct amount of current from running through it. If this is the case, the cable must be replaced.

Check all connections again

In addition, ensure that the power cable plugs into the wall and TV properly.

Step 3: Perform a soft reset on the TV

Switch off the TV and wait

Disconnect the power supply from the TV unit by pulling out the plug from a wall socket. You should leave it for a minimum of 60 seconds.

Power off the TV set and remove the cord from the socket

If the TV is off, unplug it completely from the power source and use the power button on the TV (and not the remote) for 30 seconds. 

This is useful in ensuring that any remaining power is exhausted.

Reconnect the TV power cable to the mains supply and try to turn it on again

Reconnect the mains supply to the television and see if it will power on.

Step 4: Conduct Remote Control Testing

Change the Batteries

The simple solution in case of troubles with the remote is to replace the batteries that the device has with new ones.

Utilize the TV’s Physical Buttons

In case there is no response from the remote, consider the buttons that can be pressed on the TV itself to switch it on.

Step 5: Remove External Connections

Detach Cables like HDMI

HDMI cables, USB connections, game consoles, or any related ones should be disconnected. At times, these things create power problems.

Attempt Power On

Now when all external connections are removed, again try to power on the TV.

Step 6: Make a Hard Reset

However, if the display comes on but some of the features are not working correctly – like apps are stuck or the display is damaged – the only option is a factory reset.

Find the Reset Button

This is model-specific, but the reset button is frequently placed on the rear of the television or contained in the menu settings.

Provide Remote Control Commands as Per the Instructions Shown on the Screen

Use the onscreen information to restore the settings of the TV to its original factory state.

Step 7: Be Advised about Possible Overheating

Provide Proper Ventilation

Make sure there is enough clearance around the television to allow for air movement. It should not be closed into a cabinetry or pressed against a wall.

Keep the Temperature Down

If you believe that the TV is overheating, turn it OFF and allow for a cooling period of thirty minutes before turning it ON again.
