I reached out to Jeff through the web interface for this group.?
?
He found a few issues with my mid band QMX, a couple of shorts (one of which took out my smps and cpu) and a few other minor issues (we both believe that my buttons might have gotten some Flux in them as they felt gummy to both of us).
?
Fortunately he had the tools to replace the cpu because I don't!? He also does great work.?
?
With that, I'll likely be a little bit captain obvious:
?
Make sure that the QMX is connected to the computer before even plugging in power to the unit.? Then turn it on.? This often resolved new units not connecting.?
?
Look very closely for possible solder shorts. I thought I did a good job of this, but the smps and cpu says differently.
?
Until you get the new firmware loaded and are ready to start testing the unit in full, use a current limiting power supply and set it to no more than 400 mA.?
