Schematic in PDF for the Samsung Galaxy A40, model SM-A405F, packed in a 2.65 MB RAR archive with no revision noted in the name. Diagrams of this kind let a repair technician trace power and signal lines, identify parts around the charging IC and connectors, and decide where to measure when a phone will not power up. Any PDF viewer works. Confirm that the main board version stamped on the PCB matches the document before replacing parts based on it.
