Disc Doesn't Spin. 'No Disc' Appears.

The motor is shot,Or the gears are jamming up in it, Just look for a different one, It will cost you more to have it repaired, I have got good used disc (Players) For $10 to $40 at the most for friends of mine,

If the game disc is scratched, you can get it resurfaced at a used game store or movie rental store. If it isn't scratched, the disc might just be defective. It doesn't happen very often, but it's possible.

The pladder motor that spins the disc is open, or the laser pickup is defective, the whole laser assembly would need to be replaced, not cost effective to repair cheaper to buy.

The pladder motor is bad, "disc sits on top" most be replaced to regain normal operation.

Hello
Check whether the disc inserted into the player spins. If it does not spins, replace the sled motor.

The most likely situation you have here is that the cd drive lens isn't reading, just because with a gamecube, it relies on that lens to detect if there is a disc inserted. Your best bet is to try and clean the lens with a que tip and some rubbing alcohol. Be gentle, only very gentle wipes back and forth in a circular motion, then dry it the same way. If that doesn't work, I can give you some tips on how to rip the thing apart and see if it is a connection inside somewhere

1. Ensure the games are being loaded properly. With the power turned off on the system, replace a Game Disc (printed side up) in the system, press down gently on the Game Disc until it locks on the center hub. Close the Disc Cover and press the power button ON to see if the game comes on the screen. Try this with a few of your games.
   

If Troubleshooting doesn't fix the problem, and it is happening with all your games, then your system will need repair. Check out our convenient repair options.

One time I ccidently touched the lens in my 10 year old gamecube so now the lens and the laser dont read the discs anymore because it is knocked out of anglement so you could buy a new gamecube now or buy a wii because wii's can still play gamecube disc's too.
Game Cube Disk Read Error Fix (Advanced Skill)

Sounds like you need the Gamecube sensor switch replaced. That is a small door device for detecting when the Gamecube DVD door or lid is closed allowing disc initiation to begin. When your Gamecube doesn't detect disk at all and simply continues the message: "Please insert a NINTENDO GAMECUBE DISC," this is the problem. You can test this by inserting a game disc, opening the Gamecube door, and then closing it. If the message "Please insert a NINTENDO GAMECUBE DISC" remains unchanged, and there is no spinning of the disk, then your GameCube lid closed door sensor is probably broken and should be replaced. You can search Google for Part GCPT032, or for GameCube Lid Closed Door Sensor.



An easy fix if you know how to open the Cube. It's cable simply plugs in, and it is held by one tiny screw.

If the disc does not spin or spins strangely, it is almost always because the gamecube is having problems reading the disc, and not a problem with the motor. The laser can be adjusted to a higher power, but you will need several special tools to do so. You should be able to find a guide by googling for gamecube laser adjust. If that doesn't solve the problem, you either need to replace the laser or the laser control board.
