Schematic for the Apple iMac A1419 logic board 820-00291, with the -05 revision suffix given in the name, packed in a RAR archive of about 1.89 MB. Apple numbers its logic boards with the 820- prefix, and the dash suffix marks the revision, so compare the full number silkscreened on the PCB before following the drawings. Technicians use these pages to trace power rails, check the standby and main power sequencing, find the source of a short and identify parts by reference designator. Extract the archive first and open the result in any PDF reader.
