PDF schematic labelled AM9 MB, apparently a mainboard design with a D revision marker and a date code of 22 June 2015 in the name. The device brand and model are not given, so the file must be matched against the board by checking the code printed on the PCB itself. A circuit diagram like this helps trace power rails, follow the power-on sequence, locate MOSFETs, coils and test points, and isolate a shorted line. At 2.76 MB it should open in any standard PDF reader, where searching net names speeds up fault tracing.
