Please try the solutions....If one doesn't work, try the next solution. Solution #1 Is your game disk dirty? If so, place water (you may use a sink..) on the disk, and use a towel or any other possible materials to get the water off. Proceed by placing the disc inside the Game Cube and see if it works. Solution #2 Did you insert a disc inside? Solution #3 Unplug everything and re-plug them. Hope this helps! :)
