== Power supply == The compact LC "pizza-box" power supply also uses electrolytics that leak with age. A '''dead LC PSU can usually be revived by replacing all its electrolytic capacitors''' and cleaning the leakage; any working LC PSU should be recapped pre-emptively, as it will otherwise fail. Confirm the +5 V and +12 V rails after servicing.<ref name="lc_cap">[https://quagmirerepair.com/quadra605 "Quadra 605 / LC 475"], Quagmire Repair; the Apple Macintosh LC/LC II/LC III/LC 475/Quadra 605 Service Source; and [https://pappp.net/?p=1530 "Macintosh LC Recap"], PAPPP's Rambling.
