I fried mine once on the neq6 and solved it by soldering one of the diodes. The diode is a built in redundancy one to blow if you cause an overload. If it happens again it'll fry the circuit but I do have a spare mb in case.
I can't recall which diodeit is, Have a look at the MB and see if one of these is blackened it is tiny and you may need magnifying glasses.
