hmm. not familiar with that mic. i wonder do you have global phantom power on?
may have a damaged pin block, bad connection somewhere in the mic or a bad connection between pinblock and FXLR assuming you have ruled out the FXLR itself.
If the mic has had the pin block pulled out on accident (when removing the cable) a wire could be hanging by a thread. First I'd test the cable using the behringer cable tester, it has LEDs for intermittent signal which is vital for this.
Inspect the mic near the connector end. You should find a small screw. Tighten it! The problem will likely be gone, especially if it's a phantom powered condenser mic.

You forgot to mention that it might be a left handed thread. This MIGHT fix it but the mic should get the lo side of the DC through pin 1 anyway (if not none of my cables would work for phantom because I cut any jumper between the pin 1 & the case loop (with a lot of equipment, the chassis is seperate from the shield ground and bridging this causes ground loop hum)).
I'd CAREFULY give it a look. It's not that expensive of a mic (probably not worth a service shop visit) and a connection problem might be obvious.
Are you absolutly sure it isn't the cable or another channel causing the problem? Check these thoroughly first.
