mute button won't stick

Posted: 15 days ago Quote #6183

I've successfully programmed my Visio TV manually (I'm using AppleTV with the preprogrammed 'A' button) to power on/off, volume etc. by programming manually. The only one that won't work is mute. I successfully programmed it from the Visio remote, but the behavior is that it mutes for about a second, but then goes back to regular volume. Is there a trick to this?

Try re-learning the Mute button from the Vizio remote. You may have held the Vizio mute button down too long causing the INT422 to learn the on then the off at the same time.
