Uncompromising quality at an affordable price, that's what Vizio is all about.
I have been a Vizio M6 series owner for quite some time now, and do believe me when I tell you that it is indeed one of the better ones out there.
However, just recently my Vizio TV started restarting randomly. I went online and read through several user forums and support pages. Turns out, a few Vizio TV users have been going through the same.
I compiled all the troubleshooting tips I came across into the article so that you can fix your Vizio TV that keeps turning on and off by itself, without any input.
If your Vizio TV keeps restarting, check the power cables and the power outlet of the TV. Refresh the TV and check if the remote is working properly. If the issue persists, update the TV and check the sleep timer settings and power modes. If none of the above works, hard reset the TV.
Vizio keeps restarting usually due to power cable issues or untimely commands from peripheral devices connected to the TV, like an AVR.
I have mentioned a couple of other fixes for a Vizio TV that keeps turning off and on by itself.
Check the Power Cables and Power Outlet of Vizio TV
If your Vizio TV randomly restarts, the power cable might be the culprit. Sometimes, my Vizio TV just won't turn off due to issues with the power supply!
An improper connection can entail unprecedented issues, like the refresh issue.
A good indicator of such power issues is the LED indicator on the TV. Check for the blink pattern.
Once the TV has been powered, the LED indicator fades ON and OFF. This pattern indicates Standby mode.
If the LED blinks OFF and then ON, it's suggestive of a power-related issue or a faulty motherboard. Make sure you have a snug fit at the power socket and the TV's port.
If the issue is persisting, try checking the power outlet to which you have connected the TV.
You could check the supply voltage of the outlet using a multimeter. If you don't have one at hand, try changing the outlet and check for issues.
Again, make sure you have a tight fit at both ends of the cable.
Refresh the TV Using a Power Cycle Test
Once the issue starts showing the head, one of the first things to do is to restart the TV. And this can be done quickly and safely using a Power cycle test.
A Power cycle test will refresh the system by getting rid of any temporal bugs and piled-up static charges.
These Static charges and bugs are known to cause issues on electronic devices, especially if it has been running for a long time.
The process is simple; follow these steps to do so:
- First, turn OFF the TV and unplug it from the socket.
- Wait for a few seconds (even minutes, if you may), and then press and hold the power button for a minute. Doing so will drain all the static power in the TV.
- Plug back in the cord and turn ON the TV.
Check for further issues.
Check for Remote Malfunctions
An age-old problem that we have faced ever since the very invention of the TV - a wayward remote.
Make sure your remote is not a problem. An unintentionally pressed power button or a faulty one will cause problems.
If any buttons are indeed indented, release them from the pressure and check if it helped.
You could also refresh the remote by turning the TV OFF and then removing the batteries of the remote.
Wait for a few minutes, after which, press random buttons on the remote to discharge any static charges in the remote.
Turn the TV back ON and plug back in the batteries. Check for issues.
If you have enabled CEC on your TV, try disabling the feature. Consumer Electronics Control (CEC) basically allows universal control of devices connected to a CEC-enabled HDMI port and the TV using a single remote.
To turn OFF the setting, go to Settings> System> CEC> Disabled.
Check for Updates
Another area to not ignore is the system firmware version.
Make sure you have updated the system to the latest version. An outdated device is prone to bugs and errors, especially if yours is a smart TV.
To check and update your Vizio TV, follow these steps.
1. On the Settings menu, click and open the System option.
2. Click on Check for Updates.
3. If you have any updates left to be applied, do so.
After completing the update, the TV will automatically restart. Check for issues.
Another thing to consider if and when your TV is restarting intermittently is that, if at all there are updates left to be installed, the TV usually installs them one by one.
And after each install, the TV restarts to complete the update.
Try turning OFF these updates during the updating process. You can install them later by using the steps I mentioned above.
Check the Sleep Timer Settings
Vizio TVs have sleep timers that turn OFF the TV after some time of inactivity. This setting can cause the TV to turn OFF and ON abruptly.
Even though a handy feature that helps save energy, sometimes the turn OFF period may be so low that it becomes tetchy.
Try turning OFF the setting as a troubleshooting measure. Follow these instructions to do so.
1. In the Settings menu, click and open Timers.
2. Switch the Sleep time option to OFF.
Within the same menu, you would find the Auto power OFF setting. You could also disable the option if you don't want to turn off the TV after a period of inactivity.
Restart the TV after applying the settings. Check for further problems.
Change the Power Modes of the TV
Power modes determine the overall operation of the TV.
It will decide when and how fast the TV turns OFF and ON, how long it turns ON, and also how quickly it reacts to remote commands while asleep.
Different modes exhibit different characteristics resulting in changes to the power consumed. But sometimes, these changes can be erroneous.
Abrupt shutdowns and frequent restarts are some of the byproducts of such setting changes.
To alter the settings, follow these steps.
1. On the Settings tab, click and open System.
2. Click on Power mode.
3. Then, select either Quickstart mode or Eco mode, depending on the pre-existing option.
Restart the TV after making the changes. Check for issues.
Check for Interference
Wireless interference from a nearby TV or any other wireless device can cause the TV to exhibit signs of distress.
A known issue with Vizio TVs is an interference problem with a particular model of Panasonic TV nearby. Make sure you have a fair bit of separation between the Vizio TV and any other TV in general.
Wirelessly transmitting devices, like Nintendo Switches and WiFi Routers, can also cause issues on the TV. Make sure to move such devices away from the proximity of the TV.
Also, if you have multiple Vizio TVs in the same household, move the remotes away from each other to negate cross-talk.
Hard Reset the TV
Resetting the TV will remove all the inconsistencies and discrepancies, clean the system cache, and return the system to factory settings.
It will also remove all your personal preferences and applications if you have a smart TV.
But, resetting has been able to yield results nonetheless.
You can reset your Vizio TV in a number of ways.
The most simple one is to press and hold the Reset button (most likely the Power button itself) until the screen turns OFF and then back ON again.
You also use the TV's on-screen commands to reset the TV. Follow these steps to do so.
1. On the Settings menu, click and open the System menu.
2. Click on Reset TV to Factory Settings. You will be prompted to enter a parental control code if you have set one.
5. Click on Reset TV to confirm the process.
Wait for the process to complete. You will have to reconfigure the system now. After doing so, check for further problems.
If you have a SmartCast TV, you can reset the TV using a combination of TV button commands. Follow these commands to reset your TV.
1. Press and hold the Volume down and Input button, situated on the side/back of the TV, for about 10 seconds.
2. Then, a popup banner appears on the top of the screen, informing you to press and hold the Input button to reset the TV.
3. Press and hold the Input button to start the process.
And there you have it, three different ways to reset your Vizio TV.
As a last resort, try removing all the different devices connected to the TV, and then check for the issue. Multiple connections can, at times, cause issues.
Most of these fixes can also be applied if and when your Vizio TV freezes randomly.
If your Vizio TV keeps shutting off even after trying all the mentioned fixes, contact Vizio support for further assistance.
