9. No Power On The Receptacle
If there is a case where there is absolutely no power on the receptacle at all, you have another problem. It may be that the wiring from the circuit breaker or fuse is damaged and not completing the circuit. It may be a circuit breaker has tripped or a fuse has blown. In these cases, you can reset a breaker or replace a fuse if the the circuit looks to have no visible defects. It is likely, however, that something caused the tripping of the breaker or blowing of the fuse. Try unplugging everything connected to that circuit, reset the breaker or replace the fuse, then one at a time, pluf the devices back into the circuit to find the problem, if any.
