This kind of reminds me of the time I was trying to fix a friends VCR. It worked in every other outlet except one, evrything else I plugged into the non working outlet worked. I found that if I moved the plant that was right next to Vcr, it would play, If put back the plant, VCR would not play. I tested the thoery 20 times and it was confirmed 100%. Explain that one!
