Hi Don,
?
I just finished my build of the QMX+. I have completed two other successful QMX builds.
?
So, today I applied power as suggested and wound up with the square box display. I figured it was the interface between the display board and the main board. I got the iron hot and reflowed as many joints as I could. After eliminating 99% of the possible I went back to the inside top header. So looking straight on from the front, over the top edge, start counting from the left to the right and pin #5 is the one. After I got the solder to flow from the pin to the pad?? --->? new QMX+ is on the air.
?
Hope that helps.
