Sony schematic PDF of 15.7 MB, named z3, which points to the Xperia Z3 smartphone; no board number or revision appears in the name. The document can be used to trace power rails from the PMIC, follow charging, USB and display signals and locate components when diagnosing shorts or no-power faults. Open it in a standard PDF reader and search for net names. Because related Z3 variants such as Compact or Dual models use different boards, confirm the exact model and PCB marking before trusting the drawing.
