vizio tv has sound but no picture

If your Vizio TV has sound but no picture, then you’re at the right place to find out…

The reason why Vizio TV only produces sound but the screen remains pitch black might have multiple different origins.

The main criteria are whether your Vizio TV is standalone or any video device is currently connected, where the back screen might not be on your television’s side.

Whenever the Vizio TV screen is black but there is sound, power cycle your equipment and unplug all externally connected devices.

This way you would be able to test whether the screen of your Vizio TV is black or only the input (video) source was black.

There is much more to unwrap so let’s continue!
