1st i can t say "it s broken" cuz u ll need to take off both CD, and power on the wii with only 1 CD. take appart the wii for the 1st step, the 2nd is to take appart the dvd drive, unscrew the screws on the top dvd drive to take off the dvd. (check the step by step guide) power on the wii and test your dvd drive
like markus said, nintendo do not sell repair parts so u can t found OEM spare parts, but you can easily found a shell like the original, check on ebay, dealextreme.com, focalprice.com ..... many website stores sell this kind of products
hello james, no power: check f2 and L2 fuses on the motherboard with a multimeter, about the green light and flash:it mean that u have a problem with a lcd ribbon cable (top or bottom lcd) push the ribbon cable in farther. make sure you push on both sides of it with your fingernails until it goes all the way in then latch it down sebastien
