Need Help Troublshooting OnQ LyriQ Local Source Input Problem

Hi Gang -

I am trying to complete an abandoned install of the OnQ LyriQ system in my home and have run into a little trouble...

I have everthing working with the Four Source, Eight Zone Distribution Module, meaning when I go to each of my Zones, I am able to select/recieve the 4 different sources with the Audio Keypad Volume Control for each Zone.

My problem occurs when I add a Local Source Input to a Zone. Once this is added, here are the 2 different situations I have:

1) with a local source component plugged in and active, I do hear the audio from this local source component. (good!)

2) with no local source component plugged in, I recieve Source 1 from my 4 Source, Eight Zone Module, but I am no longer able to select/receive Sources 2, 3 or 4. Pushing Source button has not effect. (problem!)

I have gone over my wiring again and again and as far as I can tell, I have it all wired correctly. But, clearly, something is wrong!!

Any suggestion on what my be the issue would be great!

Thanks a bunch!

Cindy
