Macintosh Performa 405 Troubleshooting

The Macintosh Performa 405 is a Macintosh Performa rebadge of the Macintosh LC II — the two are the same hardware, sold under different names and bundles.^[1] Because the logic board, analog board and power supply are identical, the Macintosh LC II Troubleshooting page applies in full: use it for power, video, capacitor, storage and audio diagnosis.

The Performa 405 is an LC II variant. Use the LC II page for diagnosis.

Common faults (shared with the Macintosh LC II)

As with the Macintosh LC II, the first steps on any un-serviced unit are to replace the electrolytic capacitors and inspect for PRAM-battery leakage and its corrosion, then confirm the power-supply rails. Full detail, test points and fixes are on Macintosh LC II Troubleshooting.
