Samsung SM-G531H schematic, a 7.56 MB ZIP archive for the Galaxy Grand Prime variant with this model code. Expect the standard Samsung service pages: block diagram, PMIC and charging, processor and memory, RF sections and connectors for display, camera and SIM. Use them to follow a missing rail back to its regulator, identify components by reference and pick measuring points for diagnosing no-power or no-charge faults. Extract the archive and read the content with a PDF viewer. Check the board revision printed on the PCB first.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @esquematicosparatodos. Enginerys does not host this file.
