If you’re experiencing the Vizio TV light blinking issue, then there is no need to panic, as you’re not alone on this boat, and we’ve got your back.

This issue could be occurring due to a handful of reasons, such as outdated software, which is easy to fix. On the other hand, there could be something wrong with the internal components, such as a damaged mainboard or a capacitor, which could be the culprit.

That said, we’ve put together a list of methods that you can try to resolve the Vizio TV blinking light issue.

Methods to fix the Vizio TV light blinking issue

Here’s how you can quickly fix the power light flashing issue.



Power cycle your Vizio TV

The power cycling process is harmless and eliminates any issues caused by bugs or glitches by depleting any power the circuitry might be holding. That said, if your Vizio TV light is blinking – doing a power cycle might fix that.

Here is how you can do it: 

  • Turn off your Vizio TV. 
  • Unplug it from the power outlet, and remove the power strip and surge protector if you use any.
  • Press and hold the power button on your Vizio TV for 30 seconds to a minute.
  • This should get rid of any charge or power that the capacitors and circuitry might be holding.
  • Let your TV remain in that condition for a couple of minutes 
  • After waiting, plug the TV’s power cord back into the power outlet or connect it to the power strip or surge protector. 
  • Turn on your Vizio TV and see if it functions normally. 
  • If it doesn’t, try connecting it directly to the wall socket removing the power strip and the surge protector for the time being. 

If your Vizio TV light is still blinking, the next method may help you resolve this issue.



Update your Vizio TV software

If your Vizio TV is turning on but the power light is blinking, then outdated or bugged software might be the cause. This, however, is a straightforward fix, as it only requires a simple update. 

Follow these steps to update your Vizio TV.

  • Turn on your Vizio TV. 
  • Look for the “Menu” or “V” button and press it.
  • This should open up the menu and list multiple options 
  • Select the “System” option.
  • Then, look for the “Check for Updates” option and select this.
  • Your TV should start searching for updates released by the manufacturer.
  • If it finds anything, it should give you a prompt asking you to install it. 
  • Allow it to install the latest update and wait for it to complete the process.
  • Once it’s complete, check if the blinking light issue persists.

Check for interference

External devices or peripherals can cause issues like these due to, for example, conflicting firmware. However, this issue, like the previous one, has an easy fix. It may take some back and forth, but it’s straightforward.

To check whether external devices are causing your Vizio TV power light to blink, follow these steps: 

  • Turn off your TV before disconnecting any devices.
  • Disconnect all the connected devices, such as a mouse, Bluetooth dongle, external hard drive, etc.
  • Connect one device, turn the TV on, and check whether the Vizio TV blinking light issue is resolved. 
  • If the issue persists, turn off the TV, disconnect the device, and connect the next device. 
  • Turn your TV on again and check for normal operations. 
  • Repeat this process for all devices and put aside those that didn’t resolve the issue upon connection. 
  • With this process of elimination, you should find the culprit and disconnect that device(s), which should fix your Vizio TV power light blinking issue. 



Factory reset your Vizio TV (with and without remote)

If updating your firmware and power cycling your Vizio TV didn’t work, then factory resetting it might resolve the blinking power light issue. Remember that doing this will remove all your settings and configurations and take your TV back to its original settings. 

Here is how you can factory reset your Vizio TV with the remote. In case your Vizio TV remote is not working, we’ve got you covered.

Factory reset your Vizio TV with a remote.

  • Turn your TV on.
  • Press the “Menu” button on your TV remote. 
  • It should display a list of options. 
  • From those options, select the “Reset & Admin” option.
  • This should open another menu, and from that, select “Reset TV to Factory Defaults.”
  • It might ask for a password; the default is “0000.”
  • Once you’ve entered that, select “Reset,” and it should begin the process.
  • Wait for the process to be completed.
  • Once it’s done, power up your TV and check if the light is still blinking. 

Factory reset your Vizio TV without a remote.

  • Check whether your Vizio TV has an “Input” button on the side or back. 
  • If it doesn’t, then no need to worry, as some models have the input as the power button.
  • Press the “Input” or the “Power” button for 30 seconds. 
  • Your TV should power off, restart, and begin the factory reset process.
  • Wait for that process to be completed.



Contact Vizio support

If the blinking light issue is still there, even after trying the listed methods, the next best thing is to contact Vizio support for further assistance.

Why is my Vizio TV not turning on but the light is on?

Your Vizio TV might not be turning even if the light is on due to several reasons. You might have the wrong input selected, your backlight might be faulty, or your Vizio TV might need to be restarted. However, if the display still doesn’t show anything, then contacting Vizio support is the way to go.


To sum up, your Vizio TV’s power light might be blinking due to corrupt software, and it might need to be updated. However, there are other options before that, such as trying to power cycle it, and if these methods don’t work, you can always factory reset it. While you may lose your settings and would have to do it all over again, this option generally clears all issues on electronic devices, such as mobile phones, laptops, and TVs.

That said, if the problem turns out to be severe and you’re looking for a replacement, then we’ve got you covered in that case as well with our best Vizio TV guide to help you make an informed decision.
