Full Size Wing goes BLACK

My full size wing has worked fine on my H4 since we got it. Come in today, and when the console connects the wing; all the lights go off, the backlights and LCD screens turn off. Buttons and faders still work, but no desk lamps, no displays.

I plug it into my roadhog, it's fine. Same with my HOGPC.

I'll buzz in on Monday, but figured maybe we could figure it out before then.
