Miracast on Sharp TV has stopped working with smart view and goes black

[LorrayneUk]

Why does Sharp TV go black even using Miracast on Sharp TV when it was working perfectly before? How can I fix this?

Restart your phone and unplug the TV from the wall for 5 minutes, then try again. This is the number  one fix for problems with Smart View. TV's rarely get fully shut down, so giving it a full refresh often fixes this.
