VIZIO Support | Troubleshooting SmartCast Not Working
How do I get cast on my smart TV?
Cast content from your device to your TV
Many modern smart TVs have support for the Chromecast-like DIAL protocol built in. You can cast videos to your TV from YouTube and Netflix — on your phone or computer — without getting a Chromecast.
Solution #2: Reboot Your TV, Casting Device, and Router
Surprisingly, turning ON and OFF your TV, Chromecast, and router can fix the issue.
Start with your router, as it is the most common culprit. If this does not work, try rebooting your Vizio TV. Finally, do the same with your casting device.
How to reboot your Vizio TV:
To reboot your router, press the power button or unplug your device. Plug it back in and wait 30 seconds.
Note: Rebooting should be the only time your router turns off. It should always be plugged in and turned ON for your Vizio TV Chromecast to function properly.
Vizio TV Chromecast Volume Not Working
Occasionally, your device will be paired and streaming to your Vizio TV, but there will be an issue with the volume. The sound might not be coming through, playing a different sound, or isn’t adjustable through the device.
When a Vizio TV has no volume control when using Chromecast, make sure the sound is going to the intended audio device. Restart your Vizio TV. If the issue persists, restart the streaming app or try another app. Test the volume again, then try restarting the streaming device.
First, double check issues like a mute setting or having an extra pair of Bluetooth speakers pulling the volume from your streaming device. The Vizio TV relies on a mixture of control from itself and the Chromecast device to manage its volume. If the volume seems stuck or isn’t playing, there may be an issue with the TV that will be fixed by a quick restart. If the issue is being caused by the connection or the app, restarting them is also likely to fix the most common volume issues, as long as the devices are otherwise paired. You can try restarting the streaming device entirely if the other solutions fail.
