Got it opened up and the interconnect ribbon cable was, indeed, not completely seated. I got it reseated (although it remains rather loose - head scratcher), so it may come loose once again. The little Mini booted right up with all the necessary video, audio, USB, and Airport functions intact. If the cable connection continues to be a problem, I guess I'll have to get a Genius Bar appointment over at the Tampa Apple Store to see if they can better secure the cable.

I feel so good that I had a clue as to what the problem was and have it fixed (even if it might be temporary). cool
