If Toys R' Us will take the Wii and exchange there, do that, but that's assuming 1) they will do the exchange and 2) they have a spare Wii sitting around.
More than likely they won't take the Wii if you've had it more than a week or two (assuming here, don't really go to Toys R' Us) so you'll likely just have to contact Nintendo and I'm sure there's information how to do that on their site.
