Mikrokopter Motor made its intializing chirp after landing - now doesn't run.

[NHW]

First off I'm brand new to this forum, and have only had my multi-rotor a couple months so I'm still quite the newbie to Mikrokopter.

I had a weird thing happen a couple nights ago and am wondering if anybody knows what happened based on my description.
Immediately after landing with the motors still running one of them made its initializing chirp.
I shut it down, then restarted and engine 6 wouldn't spin up.
I took it home and used the motor test in MK tools and again it wouldn't spin up.
I took a multi-meter reading at its solder points on the BL-CTRL and it was erratic.
I plugged the motor into BL-CTRL 5 and it works fine so it must be the ESC.
The LED is green on the BL-CTRL and everything is green in MK-Tools.
I haven't checked what temps the BLs have been running at since i added a camera mount and camera. Maybe it overheated?
There's no visual damage as far as i can tell and there was no smoke.
I'm not sure what happened but I'm really happy it happened on the ground.
I'm running a CineStar6 with QC3328 motors and a Cinestar gimbal lifting a t2i
Mikrokopter FC 2.1 running .84a
The BLs are V2.0 on a Hexa XL board.

Thanks!
Nick

@nick.. welcome to MRF.. sounds like a intermittent 12c error... double check all joints on the 12c system and use a magnifying glass on the dis board and BL to check for any TINY solder/wire/any fragments that should not be on there!..

Bozeman... do you know Deer Path?

Dave- Thanks for the welcome to the forum, seems like a great resource. I'll get my magnifying glass out.

I don't know Deer Path, is he a multi-rotorist?

i use a soft toothbrush to clean the electronics works fine. NHW try to connect the problematic blc into the mk usb and re initialise it pushing the triangle exclamation from mktools. (i know this is hard)
