WOW, 3-ASU is fed by 3-ftcu fed by chas7. Not knowing what role the chip places in the scenario kind of makes it hard to find a cause. It's also connected to the 3-cpu. Ground faults on the system? bad 485 cards can wreak havoc on other cabs without affecting the actual cab they're in.

I cannot see the photo but the way that any card is burn is by ground fault,
I remeber one time,the transformer get ground and all the instrument card next to it was burn;not only fire system.
