The Macintosh Performa 400 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 400 is a rebadged LC II (16 MHz 68030, "pizza-box" case). Use the LC II page for its power-supply, recap and video diagnosis.
Common faults (shared with the Macintosh LC II)
[edit | edit source]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.
