Why won't my TV remote work anymore?

Episode 1346 (1:09:27)

Hutch from Irvine, CA
Peel Remote

Hutch has a really old TV and he's hooked up an antenna to it with a digital tuner. He's tried connecting his phone to it with the Peel remote system because it has a remote app, but now all he gets is snow. Leo says that it worked once and it sounds like it's forgotten what the remote code is. It could have changed the source or that it sent a code that won't allow him to access TV channels. Leo says the problem is in the setup.
