I have 4 outlets on one circuit breaker switch. The outlet closest to the breaker box is working and the three others past the first are dead. With the breaker on, a humming sound is coming from somewhere inside the wall of the first outlet (the good one). No humming when breaker is turned off. However, when I plug in a tester on the one outlet that is working, the 120 light 'blinks' on and off . BUT, if I plug it in on a good outlet somewhere else in the house, it does not 'flash' on 120...the light is nice and steady. How do I troubleshoot this?
