Fridge Interference

Can anybody explain why my television experiences interference every time I close my fridge? I get interference every time the light of my fridge goes out. But I don’t really understand why… Anybody an idea?

    Sure! It’s quite simple - the connector to the light is shorting, creating a small arc that is creating RF interference and making those lines on your TV.

    Well, either that or you have them both plugged into the same outlet and one is poorly grounded :)

    Hmm… I see. Well… None (yes, none) of the electrical appliances in my room are grounded :-/. None of the 6 sockets in my room has grouding :(. So that could be a problem indeed…

    Hmm… I wonder if this is normal for Dutch student housing. Anyone know about this? I wonder if it’s just the sockets that aren’t grounded or it’s the whole electrical wiring that isn’t grounded… No idea…

    I live in a (200+ year old) apartment in the Netherlands and only the sockets in the kitchen are grounded. No idea if that is normal though. Never noted any interference. But that might be because the fridge is in the kitchen ;)

    Heh, my TV is *on* my fridge ;)… And since the effect assumably goes by r squared, putting the TV five times further away reduces the effect 25-fold :P.
