I have done some more testing and there is power to pin 5 (V_IN) of the Plug-in PCB #1. However, when a long hold of the left encoder is pushed there is no output on on pin #6 of this board. So for some reason Q103 and Q105 are being turned on.
I'll take a look at the PWR_ON line with the scope when I'm back from my birthday lunch -- hi!
PS: Somewhere on the group Hans described the power on sequence for the QMX. Can someone please send me the link to that message - thanks!
