Macintosh Performa 460 Troubleshooting

The Macintosh Performa 460 is a Macintosh Performa rebadge of the Macintosh LC III — 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 III Troubleshooting page applies in full: use it for power, video, capacitor, storage and audio diagnosis.

The Performa 460 is an LC III variant clocked at 33 MHz (the LC III+). Use the LC III page for diagnosis.

Common faults (shared with the Macintosh LC III)

As with the Macintosh LC III, 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 III Troubleshooting.
