Is this the right section? We don't have much in the way of hardware support so maybe it's the best you could find.
If the Wii is totally dead and doesn't even give you a Red LED when power is provided to the unit then I would look at the plug fuse, the transformer and the power connector before anything else.
Not sure what else to suggest beyond this simple stuff. If it's a Wii hardware fault then Wiihacks is probably not the best place for it, Nintendo would be.
