Logic board documentation for the Apple iMac A1419, board 820-4652 revision A, combining a schematic and a boardview file in an 11.3 MB RAR archive. It is useful for following power sequencing, locating components by reference designator and finding test points while chasing shorts or missing rails. Confirm that the 820 number and revision on your own board match, since Apple revises boards within the same model. Open the boardview in a dedicated viewer such as FlexBV or OpenBoardView and read the schematic as a PDF.
