Nokia Lumia 820 circuit diagrams for RM-825, version 1.0, archived as a RAR of around 1.95 MB. A technician can follow the power tree from battery connector through the PMIC, trace USB and charging nets, and locate display, camera, SIM and memory card circuitry when isolating a short or missing voltage. Open the archive with WinRAR or 7-Zip; the pages are typically PDF. Other RM variants of the same model may differ in RF parts, so match the code on your phone first.
