Quoted from soren:These "diode orientation" shots from the hip really baffles me.
Please try and reverse a switch diode and tell us what the result is.
I really don't understand why you think a reversed diode won't cause havoc on the switch matrix. I recently got a Last Action Hero (different manufacturer but same switch matrix design) that had all sorts of craziness. I tracked the issue down to two reversed diodes on two different switches. Having a diode on backwards can backfeed the signal through the matrix and cause phantom switch hits, which is exactly what the OP was experiencing...
