Booted up the new QMX on my bench power supply, managed to flash firmware, hooked up a dummy load to test TX and forgot to increase current limit on the power supply, so it browned out on TX. Then it died, and I'm showing a short from 5V rail to ground that is not on the power supply daughter card, it's on the main PCB.... somewhere. Any tips for figuring out where it is (and why that would have happened) are appreciated.
