Apple 820-1577 board documentation in RAR form, referencing schematic drawing 051-6537 at revision B000, roughly 1.15 MB. The file name does not reveal the format inside, though a PDF schematic is the usual content at this size. Repair work with such drawings involves following power rails from the input stage onward, locating test points and identifying suspect components near a short. Since other 051 drawings exist for this board, confirm that your PCB matches this one before relying on the references.
