Vizio Tv Youtube App Not Working

Have you recently tried watching YouTube on your Vizio smart TV only to find the app isn’t working? Frustrating error messages, endless buffering, or videos not loading are unfortunately common problems with smart TV apps.

But don’t worry – in most cases, you can get YouTube streaming again on your Vizio TV with a few easy troubleshooting steps. This comprehensive guide will walk you through the top fixes to try when YouTube stops working on Vizio smart televisions.

Check Vizio-YouTube Compatibility

The first step is ensuring your Vizio TV model and firmware version are actually compatible with the current YouTube app.

Vizio originally launched its smart TV line in 2010 with the Yahoo-powered “VIA Plus” platform. This was later succeeded in 2016 by the “SmartCast” platform based on Google’s Chromecast technology.

Unfortunately, many older Vizio smart TVs lost YouTube support entirely back in 2017 due to changing app requirements. So if your Vizio television was manufactured before 2016, YouTube functionality is not guaranteed.

Here are the key details on Vizio-YouTube compatibility issues over the years:

  • August 2017 – YouTube app stopped working on all VIA and VIA Plus Vizio smart TVs due to dropping Flash support. Affects 2010-2015 model years.
  • June 2019 – Further YouTube support removed for select older VIA Plus models with insufficient hardware. Primarily entry-level E-series.
  • Present – Only 2016+ Vizio SmartCast TVs are officially supported by YouTube. All other models blocked.

So before wasting time troubleshooting, check your Vizio television model number against Vizio’s compatibility list to see if it should work with the YouTube app.

If your Vizio TV is older than 2016 and confirmed blocked from YouTube access, then your only real options are:

  • Upgrade to a newer Vizio SmartCast smart TV that supports YouTube
  • Use a streaming device like Roku or Amazon Fire TV Stick to view YouTube

Streaming media devices essentially add smart functionality to any TV, allowing you to install apps like YouTube regardless of the underlying platform.

Power Cycle the Vizio TV

The most basic first step with any smart TV technical issue is performing a full power cycle:

  1. Unplug the Vizio TV power cable from the wall outlet.
  2. Keep the TV unplugged for 2 full minutes to dissipate residual power.
  3. Plug the power cable back into the wall outlet and turn on your TV.
Unplug The TV

Allow a few minutes for the Vizio TV to reboot and reload apps after the power cycle.

Pro Tip: Press and hold the physical power button on the Vizio television for 30 seconds while the TV is unplugged. This helps fully discharge and resets the device.

Power cycling forces your Vizio smart TV to fully shut down and restart the software, often resolving random glitches causing YouTube playback problems. It’s an easy first step before investigating more complex root causes.

Check YouTube Server Status

Before diving too deep into troubleshooting your Vizio TV itself, confirm whether the issue lies with YouTube’s own servers.

The YouTube platform does occasionally suffer regional outages that could prevent video streaming globally or in certain areas.

To check, attempt loading YouTube in a web browser or app on another device like your smartphone. If YouTube isn’t working on other devices either, that points to a larger server outage.

You can also reference the YouTube status page or sites like DownDetector to view reported YouTube problems in your region.

Check Youtube Server Status

In these cases, there is unfortunately nothing you can do but wait for YouTube engineers to resolve the outage. Server issues are usually fixed fairly swiftly however.

Reset the Vizio TV Cache

Over time, cached data and software bugs can accumulate on smart TVs leading to playback problems with streaming apps like YouTube.

Resetting your Vizio television cache clears this temporary data and often resolves random technical issues. It’s one of the simplest troubleshooting steps to attempt.

Here is how to clear cache and reboot newer Vizio SmartCast TVs:

  1. Select the Settings (gear) icon on your Vizio remote.
  2. Choose System > Reset & Admin.
  3. Highlight Reset TV to Factory Defaults.
  4. Press OK to confirm clearing all cache/data which will restart your TV.
Vizio Tv Reset & Admin
Vizio Tv Reset Tv To Factory Defaults

Allow the Vizio TV a few minutes after this “soft reboot” to reconnect to WiFi and relaunch apps. The YouTube app should then load correctly without any cached data conflicts.

Reset Your WiFi Router

Your Vizio television connects to YouTube’s servers over the internet, so problems with your home WiFi network can easily disrupt video streaming.

Issues like router hardware failures, firmware bugs, congested bandwidth, DHCP conflicts, and more can all manifest as YouTube app errors if connectivity is disrupted.

Resetting your WiFi router and modem eliminates software and performance problems to rule it out as the cause.

To quickly reboot your home network:

  1. Unplug both router and modem power cables if separate.
  2. Leave disconnected for 1 full minute.
  3. Plug power back in and wait for reconnection.
  4. Load YouTube on Vizio TV once online to retest.
Restart The Router

If YouTube still doesn’t work after router restart, investigate further network problems like inconsistent speeds.

Test Your Internet Speeds

YouTube recommends a minimum of 5 Mbps broadband speeds for smooth 1080p streaming with limited buffering or quality issues.

Using Fast.com or SpeedTest.net, test your Vizio TV’s wired network speeds to ensure adequate bandwidth.

Many homes have much slower WiFi speeds over 2.4Ghz that can disrupt streaming playback. For best results, connect your Vizio via ethernet if possible.

If speed tests show less than 10 Mbps downloads, contact your ISP regarding an upgraded internet plan. 100+ Mbps is ideal for 4K streaming across multiple devices simultaneously.

Also try moving your WiFi router closer to the TV or investing in mesh network extenders if speed is insufficient over wireless.

Update Vizio TV Software

Vizio periodically releases updated SmartCast firmware with bug fixes, security patches, and compatibility improvements for streaming apps like YouTube.

Not having the latest Vizio system software can sometimes cause YouTube functionality problems after changes on Google’s end.

Here are the steps to manually check and install updates on Vizio SmartCast TVs:

  1. Using remote, select Settings icon > System > Check for Updates.
  2. If new Vizio system update is found, select Download & Install to apply firmware.
  3. Restart TV if prompted and reopen YouTube app after completion.
Vizio Tv Check For Updates 1

Vizio smart televisions will normally update automatically over WiFi if left in standby mode. But forcing a manual firmware check ensures no updates are accidentally missed.

Update the YouTube App

Similarly, the YouTube app itself frequently receives compatibility-related bug fix and performance updates that are important to install.

Having an outdated version of the YouTube smart TV app can sometimes lead to playback failures or missing features.

You’ll need to navigate to the YouTube app page and manually update as follows:

  1. Press the Home button and highlight the YouTube app icon.
  2. Press and hold the OK button on the remote to launch the menu.
  3. Choose Check for updates and install any pending YouTube app updates shown.

The YouTube app should then reload with the newest fixes applied. Opening settings and manually updating all apps periodically is good practice to avoid technical headaches.

Clear the YouTube App Cache

In addition to resetting your entire Vizio SmartCast platform cache, also clearing data just for the YouTube app specifically can resolve software conflicts.

Here are the steps to wipe the cache for only the YouTube application itself:

  1. Load the YouTube app page using Vizio TV remote.
  2. Press and hold the OK button to bring up the YouTube app options.
  3. Select Clear cache and confirm clearing temporary YouTube app data only.

With the app cache deleted, reopen YouTube and see if videos now begin loading correctly.

Disable VPN on the Vizio TV

Virtual Private Networks (VPNs) allow bypassing regional content restrictions by masking your device’s location and IP address.

Best Vpn

However, YouTube and many streaming platforms actively block videos being accessed over known VPN server IPs.

So if you have a VPN configured on your Vizio SmartCast TV, switching this off can sometimes immediately restore YouTube functionality:

  1. Press Settings icon > Network > TV Network Name.
  2. Set VPN toggle to disabled/off position.
  3. Try reloading the YouTube app with the VPN disabled.
  4. Re-enable VPN if YouTube works normally without it.

While inconvenient, VPNS often have to be disabled temporarily for media streaming apps until more resilient solutions emerge.

Try YouTube on Another Device

Determining whether the problem is isolated to just the Vizio TV or exists network-wide is helpful for further troubleshooting.

Attempt to stream YouTube over another platform like your smartphone, tablet, or computer.

  • If YouTube isn’t working on any other devices either, focus efforts on resolving network issues with steps like router resets and speed tests.
  • Alternatively, if YouTube streams fine on other hardware, the problem likely lies with the Vizio television software itself.

In these cases, perform factory resetting of the YouTube app and full reset of the Vizio firmware.

Factory Reset the Vizio TV

If no other troubleshooting fixes have resolved your Vizio SmartCast TV’s YouTube woes, performing a full factory reset should clear any problematic cached data or software corruption issues.

Resetting the Vizio to default factory conditions essentially gives you a clean slate comparable to when first unboxing the television.

However, the process will delete all customized settings, app logins, and downloaded platforms. So first try rebooting above steps before resorting to full factory resetting.

Here are the steps to completely reset your Vizio SmartCast television:

  1. Navigate to Settings > System > Reset & Admin > Reset TV to Factory Defaults
  2. Enter parental control PIN if enabled. Default code is 0000.
  3. Select Reset to confirm erasing all content and resetting TV.
  4. Run through initial Vizio TV setup again once powered back on.

Now when relaunching YouTube, any previous data conflicts or bugs should be eliminated allowing videos to stream once again.

Use a Streaming Device as Alternative

If your particular Vizio television model is deemed fully incompatible with YouTube, adding a plug-and-play streaming accessory can often restore access.

Streaming sticks like Roku, Amazon Fire TV, and Google Chromecast plug into HDMI ports to bring smart capabilities to non-connected TVs. These include installing the YouTube app just like a smart television.

Top-rated streaming devices providing an easy workaround for YouTube on unsupported Vizio TVs:

Amazon Fire TV Stick 4K – $29.99

  • Streams YouTube in 4K quality
  • Alexa voice assistant built-in

Roku Express 4K+ – $29.99

  • Simple setup with YouTube shortcut button
  • Voice remote and private listening

Chromecast with Google TV – $29.99

  • Integrates YouTube Watch Later, Subscriptions
  • Google Assistant voice controls

With streaming sticks, you won’t have to replace the entire Vizio TV – just plug one of these alternatives into open HDMI ports instead.

Contact Vizio Support

Even after trying every recommended fix, some Vizio smart TV problems require additional manufacturer troubleshooting or repairs:

  • Outdated Vizio firmware not updating over WiFi
  • Faulty HDMI ports causing streaming issues
  • Hardware failures disrupting video apps

If no fixes restore your Vizio television’s YouTube functionality, contact Vizio support via email, live online chat or by phone at (855) 835-1032.
