Another bit of info, I replaced the PS#1 board with one from another QMX. It worked ok, but the voltage varied quite a bit just sitting there, like .3 or .4 volts.
Cliff, I hope the overvoltage didn't damage something connected to the VCC rail and the now wrong load pulls the SMPS over the limit.
Could you show please a screen shot using the other SMPS? What are Duty max and Duty cycle (min, max)?
