Use the PDF board layout to identify major capacitors around the PMIC. Probe them to find which power rail is shorted. Apply the "rosin method" or a thermal camera while injecting low voltage (1V–2V) to see which component heats up.
Be cautious when downloading PDFs from unknown hosting sites; always use a PDF viewer with security features enabled, as "patched" mobile files are sometimes used as containers for unwanted software. or a specific troubleshooting flowchart for a power or display issue on this model?
