How to Fix Issue with Vizio TV Keeps Auto Switching or Changing to Smartcast when Turning it On

The reason why Vizio TVs change or switch to Smartcast automatically is that Smartcast serves as the device’s default input when you’re turning it on. Every time the TV doesn’t detect a signal on the other inputs for 10 seconds, it will change back to Smartcast input by default. The problem is that even with a signal on another input, sometimes your TV will decide to switch back to Smartcast anyway. Now, to fix and stop this problem, just follow the guides below.

Changing the Default Input

  • This one’s relatively simple. We’re going to change the default input away from Smartcast device.
  • First, press the menu button on your Vizio TV remote.
  • Go to System and highlight the “Input at Power On” setting.
  • Change it from Smartcast to Previous Input, or any one of the inputs that you usually use.
  • With that done, simply turn your TV on and off, and the new settings should work.
  • Now, your Vizio TV won’t change to a different channel in the middle of usage.

  • Disconnecting your Vizio TV from your WiFi network disables Smartcast input, along with other internet-based inputs like AirPlay and Chromecast.
  • First, press the menu button on your Vizio TV remote.
  • Go to Network and find your WiFi network.
  • Pick the option “Forget” to disconnect from WiFi.
  • Now, turn your TV on and off.
  • With the successful change, your Vizio TV should be fixed and no longer randomly swapping inputs.
