The Nokia 8.1 uses a PureDisplay panel. The schematic shows the AMOLED/Display Port voltages (typically +5.5V and -5.5V for dual power). If one of these rails is missing, you know exactly which capacitor or boost IC to re-solder.
Locate the battery connector (J3200) on the schematic. Step 2: Trace the BATT+ line to the main fuse (F2000). Check for continuity on the PCB. Step 3: After the fuse, the line goes to the PM660. Using the diagram, measure the main power rail (VPH_PWR). If shorted to ground, the schematic helps you find the culprit capacitor (C3204, C3207) by its reference designator. nokia 8.1 schematic diagram
