B757/767/737: On various occasions a reset CB after a system failure avoided a diversion or AOG. It takes a modicum of common sense & knowledge to know when to give it a try and when not to. Much of manufacturers' speak is legal speak, not technical. If you are in the poo and need to extract yourself then certain sensible resources are necessary. Pulling/Resetting a CB on a failed minor system might be one such occasion. Either that or ignore MEL and pretend failure happened when in flight. The books will try to have you all which way. Black & white it ain't.
