This weekend my son went to turn on our Wii and it was dead. Completely dead. Power-brick-ice-cold, no-LED-indicator dead.
It was a very sad day.
As I was poking around online looking for a replacement power cord (the husband said it was likely the culprit), I stumbled across a recommendation to merely unplug the whole thing for 30 minutes, then plug it back in.
So we did. And it came back to life! We are now referring to it as the Zombie Wii, but it saved me some money and aggravation, so there you go.
