Hey.I just took out the power cable on my ps3, but then my light was gone in the same moment?How could that be :-D?
Bad wiring in the house? Sounds at least like a situation like that. Not uncommon in buildings of certain times.. older types of wiring used. And worse not ready for todays amount of electronics. So yeah check the wiring. In between time buy a few extension boxes, you know the type with more then 1 electronic socket. But most important a switch. That way you can switch it off and that way such discharges won't happen any more.
