Does anyone repair nintendo game cube? How about dvd players?

I've done some work on these items before.

In the case of the GameCube, you have to use a special screwdriver bit in order
to unfasten the security screws on the console.

If you are having problems with the GameCube, why don't you try to consult with
Nintendo customer service first?

I had a GameCube with disc read problems and Nintendo did an exchange of the
console free of charge, even though it was out of warranty by more than half a
year. I didn't have to haggle to get it, either. - Reinhart
