The Vizio Smartcast function gives consumers more options when it comes to streaming videos. It allows customers to watch 4K films and exchange photographs on their Vizio Smartcast TV with ease. However, if this function suddenly stops working, it may be quite aggravating. 

Users may get perplexed and unsure of what to do in such circumstances. As a result, here is an article to assist people who are experiencing the Vizio Smartcast not functioning difficulty.

Check out the list of solutions shown below, which I follow myself, to get the Smartcast function back up and running.

Solutions To Fix Vizio Smartcast Not Working Issue

1. Soft Power Cycle

By following these steps, you may effortlessly conduct a soft power cycle on your smartcast.

  1. On the remote, press Menu > System > Reset and admin > Soft power cycle. 
  2. Choose it and wait for it to complete.
  3. You may also unplug your TV’s power cable immediately.
  4. So, take the power cord out for at least 120 seconds. 
  5. Then, reconnect the cable and turn on the television.

2. Refresh Smartcast Home

To refresh Smartcast Home, follow these steps:

  1. Change the device’s input to Smartcast
  2. Then, go to the Menu.
  3. Change the language of the smartphone to Spanish or French from the System Menu.
  4. Afterward, close the window.
  5. As the Smartcast Home refreshes, keep an eye on the background.
  6. Change the wording back to what it was before. 

This should resolve the problem and allow you to utilize the Smartcast function again.

3. Check the Internet Connection

As discussed in the official video from Vizio, you need to verify that your device is connected to the internet. For this, follow these steps:

  1. Select Test connection from the Menu button on your remote. 
  2. There is an issue with your network connection if the response returned is ‘Network isn’t connected’ or ‘Connection speed is 0/unavailable.’ 
  3. If your Internet isn’t working, you’ll need to have that fixed first.
  4. This might entail calling your Internet service provider and requesting that they resolve the issue. 
  5. If your router is too far away from your Smartcast TV to offer a decent signal, try moving it or bypassing it and linking your Smartcast TV straight to the modem.

4. Test a Different Network

This solution might work in most cases. Follow these steps:

  1. If feasible, connect the TV and casting device to a different network to rule out anything related to it.
  2. It will assist you in determining whether or not your ISP is to blame for the issue.
  3. So, link the TV to a different network or a hotspot on the phone.
  4. Check to see whether your TV’s functionality has changed.

5. Reinstall the Casting App If Necessary

You can also try reinstalling the app. In such a case, I resort to the following steps:

  1. To begin, try turning the smartphone on and off.
  2. If that doesn’t work, remove the app.
  3. Then, reinstall it.
  4. Lastly, try pairing it with the TV again.

6. Change Your DHCP Configuration

Next, try changing your network’s DHCP settings; this will assign separate IP addresses to all of your devices, which should prevent the issue from happening.

For this, follow the below-mentioned steps:

  1. Turn the Smartcast TV off.
  2. Use any browser and input the router’s URL.
  3. Your username and password are required fields.
  4. Then, go to Settings>Advanced/Network Settings>DHCP Setting.
  5. Then, enable the DHCP Configuration
  6. If it was previously enabled, disable it and then enable it again.
  7. Then, close the Settings page by clicking Save.
  8. Turn on the television now.
  9. Lastly, check to see whether it was beneficial, and in some cases, this provides the required solution. 

7. Update the Software On Your Television

It’s a good idea to check every now and again to see if there are any new updates for your TV that you might have ignored. Hopefully, this will prevent the issue from occurring again.

  1. Go to Settings -> System -> System Updates
  2. Then, check to see if any updates are available.
  3. Update your software.
  4. Lastly, wait for the television to switch back on.

8. Restart the Router

To remove the potential of any connectivity difficulties, run a power cycle on your router. Follow the steps below:

  1. Remove the power cord from the wall plug and then turn off the router.
  2. Wait a few minutes before connecting the power cord.
  3. Then, the router will try to establish a stable network.
  4. Lastly, link the Vizio Smartcast TV to the internet and try using the Smartcast feature once more.

9. Factory Reset Settings

If none of the previous solutions work, a factory reset may be necessary. Accept that you will lose all of your account settings, apps, and other data on your device in order to solve the problem once and for all. For this, 

  • Go to the factory setting in the Menu.
  • Reset the TV to factory defaults by going to System > Reset and Admin > Reset the TV. 
  • Allow the procedure to finish on its own before attempting to utilize the Smartcast function again.

This usually solves the problem.
