# Recap mainboard (C115, C116, C118 on early boards).

# If Flipper GPU has failed (no video either), the integrated audio DSP is also lost.

== Component-level faults (deep dive) ==

=== Disc not read / "The disc could not be read" ===

This is the dominant GameCube fault and is almost always in the optical drive, not the game:

* '''Clean the laser lens.''' Wipe the lens with a cotton bud lightly dampened with isopropyl alcohol before anything more invasive. A dirty lens is the most common read failure.<ref name="gc">[https://www.ifixit.com/Wiki/Nintendo_GameCube_Troubleshooting Nintendo GameCube Troubleshooting], iFixit. Source for the laser-lens clean, the laser-power potentiometer adjustment (and the ~100 Ω lower limit), the DC-in dust check, and the burnt-out drive-motor diagnosis.</ref>

* '''Adjust the laser-power potentiometer.''' The small pot on the optical-drive/lens module sets the current to the laser diode. As the diode and pot age, resistance drifts up and read power falls, so a machine that reads originals but not backups — or has stopped reading altogether — can often be recovered by lowering the pot resistance slightly to raise laser power. '''Do not take the resistance below about 100 Ω''': over-driving the diode destroys it. Make small changes and test.<ref name="gc">[https://www.ifixit.com/Wiki/Nintendo_GameCube_Troubleshooting Nintendo GameCube Troubleshooting], iFixit. Source for the laser-lens clean, the laser-power potentiometer adjustment (and the ~100 Ω lower limit), the DC-in dust check, and the burnt-out drive-motor diagnosis.</ref>

* '''Drive not spinning at all.''' If the disc never spins and the drive is silent, the spindle/drive motor may be burnt out — the fix is a drive-motor repair or a replacement optical drive. A tired laser that is beyond adjustment likewise needs a replacement drive.<ref name="gc">[https://www.ifixit.com/Wiki/Nintendo_GameCube_Troubleshooting Nintendo GameCube Troubleshooting], iFixit.

=== No power ===

If the console is dead with a known-good supply, check the DC-in jack for dust or dirt (blow it out and reseat the plug) before suspecting the internal regulator board.<ref name="gc">[https://www.ifixit.com/Wiki/Nintendo_GameCube_Troubleshooting Nintendo GameCube Troubleshooting], iFixit.

=== Notes ===

The optical assembly is the wear item on this console; when lens cleaning and a cautious pot adjustment do not restore reliable reading, budget for a replacement drive rather than chasing the symptom further.
