Main logic board (MLB) schematic archive for the Apple iMac 27-inch A1419, project D8, document 051-9504 at revision 7.0.0. The 2.44 MB RAR should contain the multi-page drawing used to follow power rails, check standby and main voltages and locate faulty components on this all-in-one board. Apple numbers its schematic documents with the 051- prefix, while the board itself carries an 820- number. Compare the board variant and revision with your hardware, since the A1419 had several MLB versions.
