Soleil, if you do have your Wii repaired, there is a two year warranty from Nintendo on the repaired one.
I sent mine in because it wasn't reading Gamecube discs, and was making a funny noise, like something was buzzing inside of it. I took it apart, and found the part that needed to be tweaked, to stop the buzzing noise, but still was not able to get the Gamecube discs to read.
