I would call Nindy support they're very helpful but first try disconnecting the power supply. My Wii died a couple of times when I first got it, it turned out to be the power supply (I tested it with a multi-voltage tester). It turns out the power brick wasn't truly broken, it shuts off if it senses an unclean fluctuating power source to protect the console systems flash memory. To reset it you need to unplug it AND remove ALL other connections from the console (sensor bar, TV cable) you also need to remove any memory cards. Wait 20 mins and reconnect everything now it should work if not call Nintendo. My problem was the mini fridge in the game room would make the voltage fluctuate on the same circuit where the Wii was plugged in. I just bought a cheap computer UPS and I've never had the problem since. Another thing to keep in mind is that there is also a standard 3 amp fuse inside the brick but I wouldn't try to replace it unless your system is out of warranty.
