Wii won't spin up Wii games, only GC

Anyone have any pointers for fixing a Wii that won’t read Wii games? It reads Gamecube discs fine, but won’t even spin up Wii games (we’ve taken the top cover off and can see the discs moving/not moving).

I fixed it! There was a little metal tab that was in the way and I bent it back and now the disc spins freely.

My wii is doing the same thing as yours. Could you tell me how you fixed it?
