The other day, I had one of the lamps on the end table start blinking. I unplugged it, went out to the barn, got a spare receptacle and replaced it. The receptacle was original to the house so it needed changed anyway. There was a piece of the plastic housing broken but no evidence of shorting that I could see.
Plug the lamp back in, about 10 minutes later it started blinking again. I switched the lamps and realized the same lamp was blinking in the other receptacle, the first...
Once again technology fails me.
