  • Device memory leak
  • Internet connection problem
  • Unstable network

Vizio SmartCast Issues– Five Fixes

If you have issues with your Vizio SmartCast not working, below are five fixes that can help you restore viewing:

1. Soft Power Cycle

Your Vizio SmartCast might have software issues if it is not working. To fix this issue, you need to conduct a soft power cycle. A soft power cycle involves restarting the module, so all temporary configurations get deleted.

Once you conduct a power cycle and turn on your device, it will re-initialize all the temporary settings. Below is a guide on how to conduct a soft power cycle on your device:

  • Get the TV remote and press the Menu bottom
  • Click on system and select Reset & Admin
  • Proceed to click on Soft Power Cycle
  • Your router will power off and restart

Your Vizio SmartCast should start working once you do this. Alternatively, you can do the following:

  • Use the power button on the TV to power off the device
  • Unplug the TV from the power source
  • Press the power button of the TV for 20-30 seconds – remember to keep the TV unplugged from the power source.
  • Replug the TV to its power source
  • Press the power button of the TV for 20-30 seconds
  • Power on the TV
  • Then wait for the Vizio SmartCast Home to appear on  the screen

This solution should do the trick and fix the issue.

2. Check Network Connection

Ensure that your network connection is strong and that you have correctly connected your device to a network. To check if your connection is correct, you can run a connection test as thus:

  • Go to the Network Menu bar
  • Click on Run a Test Connection

After the test, if the result shows that you did not connect your device to a network or that the speed is zero or unavailable, you can do the following to fix it:

  • Soft power cycle your router – you can do this by unplugging your TV from the power source.
  • Wait for about ten minutes, then plug back your device

Your device should be working well once plugged back in. Ensure that you have a stable internet connection or your network’s signal strength is strong enough to initiate your device.

3. Switch to HDMI 1

You can switch your Vizio Tv connection to HDMI 1 through the following steps:

  • Check the input selection controls on the TV remote
  • Press the button to display available inputs
  • Choose HDMI 1 out of the available inputs
  • Wait till the program loads

If a No Input signal prompt comes up, follow this guide to clear it:

  • Click the Menu button on the remote
  • Highlight and select System
  • Choose Reset & Admin
  • Click on Soft Power Cycle
  • The TV will shut down, power it back on

Once it is on, a prompt will display on your screen – SmartCast is starting up; please wait. The prompt should clear off in a minute, then change your device back to SmartCast input.

4. Factory Reset

You can do a factory reset on your TV to erase any custom settings. Below is how to factory reset your TV:

  • Press the Menu button on the remote
  • Go to Reset & Admin
  • Click on Reset to Factory Settings
  • Select Reset

Once you do a factory reset, the next step will be to set up your device.

5. Refresh DHCP Setting

Your device might stop working if you are using an incorrect or non-optimal Dynamic Host Configuration Protocol (DHCP) setting of your network. DHCP is the connection that ensures that no two devices have the same IP address to avoid connection issues.

However, in some cases, the DHCP might be unresponsive and might not assign an IP address to the SmartCast system. If your Vizio SmartCast is not working due to the reasons mentioned above, you will need to re-enable the DHCP setting.

Below is a guide on how to re-enable the DHCP setting of your network:

  • Power off the TV
  • Launch your browser
  • Open the router’s URL
  • Input the registered username and password
  • Open the router’s setting
  • Search for the DHCP section of the router in either Advanced, Setup, Network, or Local Network settings.
  • Enable the DHCP – if it is enabled, disable and re-enable it
  • Save the settings and exit the setup section
  • Proceed to turn on the TV
  • Check if it is working properly
  • Alternatively, edit the router settings to use Google DNS and check if it is working.

The guides mentioned above should fix the issue your Vizio SmartCast might be having. However, you can contact Vizio SmartCast support for help if it doesn’t.
