Question Please advise: Behringer DEQ2496 with microphone hum

I just bought a Behringer DEQ2496 with an ECM8000 microphone on ebay but i have a loud 50HZ hum (visible whenever i use the RTA). I changed microphonecable and connectors, tried another AC outlet, unplugged all that was not needed etc. but the hum stays. A 50Hz sounds like a power supply and/or grounding problem but i have no idea what to do about it.

Anyone can help me get rid of this hum?

Default ECM 8000 hum repair

I repaired mine today. There are 3 screws holding the connector inside the tube. Undo them, then gently slide out the pcb. There is a wire connected on the other end connecting to the capsule, so be careful not to tear it out. The PCB goes out all the way and then a cm or two. There is a brass connector near the black plastick holding the three connector pins. The brass connector is meant to conduct ground to the mic housing. Apparently this was the case. I bent out the brass connector so it had better contact with the housing.
I also cut along the edge of the pcb to remove the insulating sleeve and to access the pcb. I was looking for some cold solder joints, but there were none. I resoldered yellow caps on the bottom of the pcb with some fresh solder just to make sure. I then put back the insulating sleeve secured it with the electric tape and slid everything back in and fixed the connector. The mic now works like new.
I guess the inflexible brass connector was the cause since there were no apparent cold solder joints. So try fixing it first.
