Advanced Flight "AHRS OFFLINE"...?

I have a legacy Advanced Flight Systems 4500s and 3400s in my 9 year-old RV-9A that I've owned for a couple of months, about 40 flight-hours. It's a great system and has been working perfectly until the other day. After going through its usual location finding routine, I got the big red X and the warning "AHRS OFFLINE". I still had navigation and non-AHRS function, but no attitude etc. It has a G5 for redundancy and the 430W is providing navigation function as usual.

So, I'm pretty new at this glass cockpit stuff, and I did post over on AFS Forums too. How do I troubleshoot this lack of AHRS connectivity? Is the AHRS module dead? Bad connection? Software problem?
