Vizio TV Freezing At Random: How To Fix [2022]

Owning a TV is a big step, a big step towards your entertainment needs. You can watch your favorite shows and movies, play your preferred games, or even use it as an external display for your PC.

I have been a Vizio M Series user for quite some time, and the TV has never let me down, whether in terms of quality or performance.

But, once or twice the TV did stutter and freeze for a while. Nothing serious, though, and the TV did return to color after a quick restart.

But a few days back, the freeze came back again, and this time it took a little more than a restart to fix it.

Vizio TVs freezes at random because of an outdated system firmware or because of a slow internet connection. Check your internet connection and perform a power cycle on the TV as possible troubleshooting measures. If the problem arises while using an app, check for app updates or try reinstalling the app. Sometimes, you may have to Hard reset the TV to fix the problem.

I solved my freeze issue by resetting the TV. But this might not be necessary in your case. Try some of these troubleshooting measures before pulling the plug on your TV.

First, Power Cycle the TV

Power Cycle the TV

Nothing fancy here, just the plain-old restart, but with an additional step or two. As soon as your TV starts acting up and the whole screen looks like a surrealist painting, try power cycling the device.

A power cycle test will remove all nascent bugs and stored-up static charges in your TV and make it faster and more efficient.

All you have to do is to turn OFF your TV and then unplug it off the socket. Leave the TV in this state for a couple of minutes.

Then, press and hold the power button for about a minute or so. Repeat this step a couple of times. Doing so will bleed the TV off any static charges.

Plug back the Power cable and power ON the TV. Check for any discrepancies. Try this step especially if your Vizio TV restarts randomly.

You could also perform a soft power cycle test on your TV using the TV interface commands. If you are facing the freeze issue while using a specific app, try this step.

Follow these instructions to perform a soft power cycle on your Vizio TV.

1. Press the Menu Button on the Remote to open the Setting tab on the TV.

2. Click and open the Systems menu and then click on Reset & Admin.

3. Select the Soft Power Cycle option and click on Yes to confirm.

Wait for the process to complete and then check for the issue.

Check the Internet Connection

Check the Internet Connection

If you have a SmartCast TV or any other Smart TV offerings from Vizio, proper internet connectivity is vital for the optional performance of the TV.

An unstable internet will cause constant freezing issues while streaming or using apps on the TV. The minimum required data limit for various streaming qualities is as follows:

  1. SD- min. 3 Mbps.
  2. HD- min. 8 Mbps.
  3. Live TV- min. 10-15 Mbps.
  4. 4K- 16 Mbps.

These data requirements can vary from platform to platform, like Youtube may have a lower data limit than Netflix. You can check the internet speed using a speed-testing app on your smartphone or PC.

Make sure you have a good enough connection and stable speeds from the router. You can check your internet connection by following these steps on your TV:

1. Press the Menu button on the remote, and then select the Network option.

2. Select the "Test connection" option to run a connectivity test on the TV.

If a message that reads "Download not available" pops up, you have an internet problem. Try restarting the modem using the same Power cycle test as we did with the TV.

Unplug the Router/Modem from the outlet and wait for a couple of minutes. Press and hold the various buttons, most preferably the power button, for a good minute or so.

Plug back in the router and check the speed using the same speed testing app.

Switch to a higher WiFi channel/bandwidth

The traditional 2.4GHz WiFi band has some issues with the bandwidth allocation if the traffic is high on the network.

If there are a lot of devices connected to the same network, one might experience higher latencies while using the internet.

A 5GHz band doesn't have any such limitations and can accommodate higher traffic without sacrificing the latency. If your Router supports a 5 GHz band, try switching the network to this particular band.

Most modern Vizio TVs support a 5GHz connection. Follow these steps to switch the internet connection.

1. On the Menu tab, click and open the Network option.

2. Select WiFi and click on the 5GHz band.

3. Enter the password to set up the connection.

Check for Updates

Next up, check for updates on your TV. Running an electronic gadget on an outdated version opens the sluice gates for bugs and errors, waiting to disrupt the proper functioning.

Usually, Vizio TVs are programmed to automatically check and update the firmware to the most current version. But for some odd reason, this feature may get disabled.

Make sure to check and update your TV every once in a while. To check for updates on your TV, follow these steps.

1. On the Menu tab, click and open the System option.

2. Select Check for Updates.

If you have any updates left to be applied, do so. Wait for the process to complete. Check for further issues.

Tinker With the TV Settings

Tinker With the TV Settings

Sometimes, a wayward setting can cause the TV to freeze up abruptly. Try taking a gander at these TV settings once you experience frequent freezing issues on startup or any black screens.

So let's get right into it, shall we?

Check the Auto Power OFF Setting

Almost all modern Vizio TVs have auto power-off settings, which will shut down the TV after 10 mins of inactivity.

Sometimes, altering this setting can solve the freezing issue. The exact reason for such a fix remains a mystery but has been proven helpful.

To check the setting, follow these steps.

1. On the Menu tab, click and open the Timers option.

2. Click on the Auto Power OFF tile and disable the option.

3. Within the same settings tab, you could also change the Sleep time option. This option will let you choose the time period after which to put the TV to sleep.

Restart the TV after changing the setting.

Change the Picture Mode

Try altering the picture mode of your TV as a possible fix for the freezing issue. Sometimes, changing the color profile can obviate any discrepancies with the picture.

To change the picture mode on your TV, follow these steps.

1. On the Menu Tab, click and open the Picture option.

2. Click on Picture Mode to open up the different options.

3. Toggle between different picture modes and check for issues after doing so.

Make sure to restart the TV after changing the mode.

Turn OFF CEC

Consumer Electronics Control(CEC) is a communication protocol by which you can control the devices connected to the TV through an HDMI port using a single universal remote.

This means that you can control either of the devices using the TV remote or the device remote. A pretty handy feature, right?

All modern TVs come preinstalled with such HDMI ports, but you will have to turn ON the feature on some TVs.

Sometimes, these ports may cause freezing issues on your TV. If that is the case, try disabling the option.

To do so, follow these steps.

1. On the Menu tab, click and open the System option.

2. Click on CEC and toggle the setting OFF.

Restart the TV and check for further problems.

App Related Fixes

App Related Fixes

If you are facing freezing issues while watching content on an app, first check your internet connection. Then, try logging out of the service.

Apps like Netflix and Hulu frequently flaunt freezing issues. Inherent bugs and errors that might have taken shop in your device after a recent update may be the reason.

After logging out of the service, perform a restart/power cycle on your TV, and then try logging in back. Check if this helped solve the issue.

If not, you might want to check for updates or uninstall the app and install it again.

Updating and Reinstalling the App

Vizio SmartCast TVs do support streaming services and apps, unlike their regular offerings. And these apps might require frequent updating to get rid of any bugs and errors.

If updating doesn't help, try uninstalling the app and reinstalling it after restarting the device.

To update or uninstall the service, follow these steps.

1. Press the V Button on the remote to SmartCast Menu and view all apps.

2. Highlight the app in question and then press the yellow button to open up an options tab.

3. In this tab, you can find either of the options.

Keep in mind to restart the TV after updating or uninstalling the app.

Hard Reset the TV

Finally, if none of the above fixes have been able to yield results, try Factory resetting your Vizio TV.

A factory reset will change all the settings to default ones, clear the cache memory and even remove all the apps you have added. Sounds harsh, right? Well, all in or nothing, that's how things work.

There are a couple of ways in which you can reset your device. First, let's look at the universal method, shall we?

Follow these instructions to reset your TV using the interface commands.

1. On the Menu tab, click and open the System menu.

2. Select the Reset and Admin option.

3. Click on Reset TV to Factory defaults.

4. Enter the Parental control code(enter 0000 if you have not set one).

5. Click on OK to confirm.

Upon process completion, you can set up your TV again from scratch.

For those who own a SmartCast TV, you can reset the TV using a combination of button presses on the TV itself. Follow these instructions to do so.

1. Press and hold the Volume down and Input button for about 10 seconds.

2. A popup message will appear instructing you to press and hold the Input button to reset the TV.

3. Press and hold the Input button to start the reset process.

Do note that factory resetting can also wipe out all channels from the Vizio TV.

And that pretty much wraps up this troubleshooting guide.

Conclusion

Freezing issues, or pretty much any other issue, as a matter of fact, can make your day a bit harder. But it's these challenges and how we overcome them that defines our very fighting spirit.

This guide will aid you to overcome one such issue.

A thorough check for loose cables and connections, especially the power and HDMI cables, can assure that side of things. Checking the Router settings, mainly the DNS settings, can also prove helpful.

If none of these tips were helpful, your TV might have a damaged PCB/motherboard. If that's the case, contact the customer services of Vizio for further assistance.

Frequently Asked Questions

How to cast/share my phone screen on Vizio TV?

Vizio SmartCast line of TVs does support smart features like casting, using the inbuilt Chromecast feature. Make sure that both your TV and the casting device are connected to the same WiFi network. Open the application/service you want to cast, and then click on the Cast icon. Select the SmartCast TV from the list to start sharing.

Why does my Vizio TV keep glitching?

A glitchy/flickering screen is due to problems with the display. Ensure that you have all your cables and connections firmly attached. Try power cycling the TV; also, check for updates. You might as well reset your TV at this point. If none of these tips were helpful, chances are, you might have a damaged backlight panel. Contact a professional for further inspection.

What causes vertical lines on Vizio TV?

The reason for vertical lines on your Vizio TV is dead pixels. A dead pixel essentially means that the smallest unit of the TV's LED/LCD panel has become unresponsive to picture generation. The pixel doesn't appear to be black because it is backlit by the backlight panel. Over time, a whole row or column of these dead pixels may show up, resulting in a line of unresponsive dead pixels. The only fix to such a problem is to replace the display of the TV.
