Advertisements This has happened a few times and I'm not sure what the problem is. I use a harmony one to control my roamio basic as well as tv, denon receiver, etc. I click on the "Tv" activity and everything comes on (tv, denon). Of course the roamio is always on. But when you try and change channels the orange light doesn't illuminate for any button press. You can control the volume of the denon which leads me to believe it's a roamio issue. I'll have to dig around and find the tivo remote to see if it exhibits the same issue. Just wanted to see if anyone had any similar experience?
