Vizio TV Keeps Rebooting/Restarting: Causes and Fixes

Having owned a Vizio TV for a few years now, I was extremely frustrated when it recently started to reboot or restart itself randomly. I was determined to get to the bottom of the issue and find a fix, so I decided to do some research. After hours of digging, I uncovered the causes of the auto-rebooting and several solutions to try. In this post, I’ll share what I learned and the different fixes I tried to get my Vizio TV working properly again.

Well, just like any Smart TV, Vizio TVs have their share of reported problems. Common problems of a restarting Vizio TV concern unstable electricity, faulty power cables, software issues, or a defective remote.

Issue/ProblemDetailsPossible Solution(s)
Changes in TV ConfigurationError in system compatibility, cache overloadPower cycle the TV
Unstable Electric SystemInsufficient power, electricity fluctuationUse a voltage meter, call a technician, or install a voltage stabilizer
Faulty Cables, Connectors, AdaptersDamaged components affecting performanceReplace faulty cables, connectors, or adapters with compatible, high-quality ones
Remote Control IssuesIndented button, battery terminal glitch, enabled CECRestart the remote, replace batteries, disable CEC feature
Pending UpdatesMultiple updates in queue, TV restarts after each updateCheck for updates, apply updates, turn off the TV during updates to avoid restarting loop

Common Issues Why a Vizio TV Keeps Rebooting/Restarting

Below, we’ve listed five common causes of restarting/rebooting that Vizio TV owners experience. 

  1. Changes in the TV’s Configuration

There may have been changes in your TV’s configuration that caused an error in the overall system compatibility. 

It may also cause an overload of cache that makes the system run slower. In short, the system might simply be glitching.

  1. Unstable Electric System

Power fluctuations are the enemy of TVs. 

Your Smart TV may not be getting sufficient power to run its features because of improper connections or electricity fluctuation, thus the restarting issue.

  1. Faulty Cables, Connectors, or Adapters

Having damaged cables, connectors, or adapters can heavily affect the software and hardware of your Vizio TV

The TV will have a harder time running on optimal performance simply because of worn out or ruined wirings—it can’t deliver electric currents properly.

  1. The Remote Is Not Working Properly

In some situations, your TV may not be the problem at all—it may be the remote. 

The problems related to the remote can be an indented button, a glitch in the battery terminal, or an enabled CEC feature.

  1. Time for an Update!

Pending updates may be the reason for the restarting loop. Chances are, there are multiple updates in the queue, and your TV restarts for each completed update.

 Ideally, your TV needs the updates to give you the latest firmware and steer clear of any potential bugs. 

Solutions to a Rebooting/Restarting Vizio TV

Here’s how we suggest you go about your Vizio restarting issue:

  1. Do a Power Cycle Test

Power cycling is effective in removing internal glitches and bugs that cause an error in your TV’s system. To perform a power cycle, follow these steps:

  • Press the hard power button to turn off your TV.
  • Unplug the power cable from the electrical socket.
  • Press and hold the power button for 30–40 seconds.
  • Cool down your TV for 30 minutes or an hour to run its diagnostics.
  • Plug the cord back in and turn on the TV to check for further issues.
  1. Use a Voltage Meter or Call a Technician

Concerning an unstable electric system, using a voltage meter can save a lot of work by checking the amount of voltage sent to your electronic devices. 

It can detect any damaged connections, so you’ll know which one to replace.

If your power outlet is the culprit, then it’s best to call for a technician to get it fixed. Alternatively, you could install a voltage stabilizer to maintain constant voltage regulation.

  1. Shop for New Cables, Connectors, or Adapters

If the issue lies in your physical components, you can replace them with new ones of the same or better quality to ensure optimal performance on your TV. 

Contacting customer support can provide you with compatible and accurate replacements. 

  1. Restart the Remote and Disable the CEC Feature

Restarting the remote to get rid of internal glitches can be easy. Here’s how you can do it:

  • Open the battery compartment and remove the batteries.
  • Press and hold any button for 20 seconds.
  • Insert the batteries back and see if your TV still restarts.
  • If it doesn’t work, simply change the batteries, then test your TV again.

Another solution is to disable the CEC or the Consumer Electronics Control feature. This feature allows other devices to switch your TV on if it’s connected to a CEC-enabled HDMI port. 

Turn this function off by pressing Menu > System > CEC > Disable by sliding the bar. Afterward, reset your Vizio TV by turning it off for 10 minutes to let it cool.

  1. Check for Any Updates

Let’s try checking for updates to get the latest feature for your firmware to run smoothly and without restarting. 

To do this, use your remote and press Menu > Settings > Check for Updates > Apply. While the updates are processing, consider turning your TV off to avoid going through a restarting loop.

It’s possible that even after all the previous solutions, your Vizio TV might still keep rebooting/restarting. If so, contact the Vizio Support team to help you determine the issue and provide an effective solution.

Wrapping Up

If your Vizio TV keeps rebooting/restarting, this may be due to common issues like unstable electricity, faulty components, rebelling remote control, or a simple update and reboot requirement.

Regardless, all these problems have solutions, and hopefully, our guide will help you get your TV running normally.
