Help..My z5500 has gone dead. it is on a UPS/surge protector. The fuse was tested and its good but normally you hear a pop when the module is turned on and the Control pad button comes on red. None of the above is happening it is just dead. Tried different power outlets and switched UPS/surge. Anybody have any smart and informative suggestions as to whatelse to check for or who to take it by for check up(and doh tell meh a vet)
