Qualcomm RB5 Drone cant be turned on

[Alejandro M.]

Hello everyone.
After properly setting up the drone and preparing it for its first flight, while we were doing some RC configuration and testing the QGC mission control, the drone suddenly turned off and the wall power supply looked as if it was down or not working. I then tryed to connect the wall power supply to a different socket and it seems to be working properly but as soon as I try to connect the drone back it turns off so thats why I'm guessing that the problem may be coming form the wiring or the integrated circuit that is in charge of the power supply of the drone. I cant see any burnt on it or any weird smell that could be used to verify that something has gone wrong while it was on. Is it there anyway I can get another integrated circuit to change this one, or is it there anyway I can fix this?
Thank you very much and I'm looking forward to your answers.
Regards.

If you arm with the wall power supply, the electronics in the drone will be destroyed

Hello @Chad-Sweet thanks for your fast response. Im doing check with the multimeter and everything looks more or less okey, is it possible that something else happenned? In case it isn't what should we be doing next?

Hi @Alejandro-M
It's highly likely the ESC or Power Module board was irreversibly damaged from this configuration (normal lab wall power supplies cannot power a drone without near certainty of failure).
If there is a short on the +5V_DCIN to GND, you can easily observe that, but the other failure mode could be an open circuit which will not show up on a DMM easily.
Your best course of action may be an RMA with us so we can explore the drone and find the failure(s) and offer you replacement options to get this platform back up and running.
