I'm not sure what this means or if I should be worried and yelling for an electrician. I woke up this morning, and all of the top outlets are not working in my living room. I unplugged the lamp from the top and put it in the bottom one, and that one works. I did this on three of the outlets in this room and the lamp or tv now will turn on, but not if I plug the cords into the top. Does anyone know why this would happen, and what do I do about it? Thanks so much for any help!
