Many users reported about the issue on the Reddit community:

When I turn my Vizio smart-TV on, the Smartcast screen usually comes onto the screen. As of maybe 2 days ago, this screen does not even load – all I get is a black screen. Netflix and other such apps will work if I press the dedicated button on my TV’s remote, but then there’s no way to access any apps that do not have a dedicated button (i.e. Youtube TV). Casting to the TV seems to be intact.

Anyone else having this same issue? If so, has anyone figured out how to fix it?

And after examining the problem in depth, we have found a series of possible causes that are responsible for the problem. Here is a list of issues that lead to problems.

Why Is My Vizio SmartCast TV Not Working?

  1. Unstable internet connection: If you have an unstable internet connection then this is probably the most common cause. In this case, switch to a different internet connection or contact your ISP.
  2. Software glitches: It's not uncommon for problems to occur due to some kind of software glitch with the smartcast. In this case, the TV power cycle works for you to clear the temporary configuration and reconfigure it.
  3. Non-optimal DHCP Settings of your Network: The problem may occur due to incorrect or non-optimal DHCP settings on your network. So, changing network DHCP settings might work for you.

Now that you know the possible causes of the smartcast not working on Vizio TV, let's head over to the verified fix series that other affected users used to fix the issue successfully.

How To Fix Vizio TV Smartcast Not Working?

Before starting with the solutions given below, make sure you have: stable internet connection and check your device is working properly.

As said above, incorrect settings can also cause problems and refreshing your network's DHCP settings may work for you.
