Why Are Apps Not Working on My Vizio TV?

The apps can stop working because of a variety of reasons. It could be because of an issue with the television or a problem with your network. Either way, you can narrow the problem down by trying different troubleshooting tips. 

The apps can stop working if the TV’s firmware has a bug or fails to start correctly. It can also be because of settings that hinder internet connectivity or the general operation of the TV. A poor internet connection is also a possible cause considering most of the apps on Vizio TVs require the internet. 

The suggestions below will help you get your TV up and running.
