My Wii died after about 3 hours of playing it....so sad.
My wife was playing and it just turned off and would not turn back on. Luckily I was able to test with another AC adapter to confirm that was the problem.
2 Notes:
1. I first called gamestop, there response was that if I did not buy the extended warranty from them then they can't help and I cannot return it.....
2. I then called Nintendo, it took a few tries to get through to a person, the first few times it just said all reps were busy and to try later.
Once I got the rep on the phone he was totally helpful, and offered me 3 chooses:
1. they will overnight a new AC adapter
2. they will overnight a new Wii, just the console
3. they will send a return label and I send in the whole thing for free repair.
I choose option 1, he said it will take a day or two to be shipped, but it will be mailed overnight.
That was yesterday so I don't have it yet, but I was happy with Nintendo's customer service...and disappointed by Gamestop.
