inside all disc drives are lasers that move inside grooves to read the discs, well there are little gears that spin that moves the laser, on these gears are some king of (white sticky substance) that act as a lubracant so the gears wont dry out and get stuck, at least all the cd and dvd players i'v taken apart, well anyway the laser on my gamecube seems kind of tight and I was wondering if the gears inside that moved the laser were off balance or got stuck, this happened to my ps1 and i took it apart and put cooking oil on the gears that moved the laser and it solved all my problems, does anyone know how to get inside the disc drive on a gamecube and reveal all the gears?
