I had a problem with mine, we had a momentary power outage in the house and after the power came back on the Wii did not even light up. I unplugged the Wii and plugged it back it a different outlet. No help. Then I unplugged it and left it unplugged over night. The next morning when I plugged it in it worked fine. I spoke with some co-workers who also have Wii's and I have found that this can be pretty common. Anyway it's working fine now.
