It depends on the problem , you should specify.
You can fix your wii's Fan by gonig online and ordering a fan along with their special Ds and Wii Screwdriver this is if your wii is overheating and shutting down for a few hours, after only playing 30-45minutes of gameplay.
After taking apart everything theres a protective metal case if you just pull it comes off, you can then replace the fan. Do not lose the screws their custom made just for the wii.
all gamecube games are compatible with wii. i think your wii is broken.
No! Who in there right mind would buy or even trade a perfect wii for a broken one!
it means your wii console is therefore broken beyond repair
No it does not. If your Wii is broken, it broke for other reasons.
Contact Nintendo and get it in for Repairs.
Your sensor bar is broken, or you have marks on your Wii Remote.

play the wii with your mates
3 possibilities: either the disc is dirty, the disc drive is broken, or (you better hope this is not the case) the wii is broken. I'm not a wii specialist or anything so don't put all your trust with what I'm saying.
call Nintendo
If your Wii Sports game has broken, simply get another. Your memory will stay because the information is not saved on the disc itself, but on the memory card on the Wii.
