How do you unpair your iPhone from a smart TV?

I keep hitting the tv button when I'm trying to tap the full screen button on the YouTube app, and it connects to the tv. How can I disconnect/unpair my phone from the tv so when I press the button, it won't connect to the tv.

You should be able to do this either from the YouTube app on your TV or by changing the account options if you load youtube via a webpage (not all versions of apps allow it).

Loaded via a web browser, you need to go into your account details and select the "Connected TVs" option.

The same way you unpair any other device.
