If you identify a shorted power rail (e.g., VPH_PWR reading 0.000V in diode mode), do not plug in the charger. Inject a low voltage (typically 1.0V to 2.0V, matching the rail's rating) using a DC power supply. Apply freeze spray or rosin flux smoke to the board; the shorted component will heat up rapidly and melt the frost first.
Use the diagram to test the PCB for malfunctioning capacitors, resistors, or voltage regulators.
Vivo U10 Schematic Diagram Download: Ultimate Repair Guide The Vivo U10 is a budget-friendly smartphone known for its reliable performance and hardware. However, like any electronic device, it can develop motherboard faults over time due to liquid damage, drops, or component wear. For mobile technicians and DIY repair enthusiasts, troubleshooting these complex hardware issues requires a precise map of the logic board. vivo u10 schematic diagram download
The oldest and largest global community for phone repair. Look for verified threads in the Vivo hardware repair section.
Open the Vivo U10 schematic and locate the main battery/charging connector interface. Identify the . Plug a charging cable into the device and measure the voltage at this test point. It must read a steady 5.0V to 5.2V . If the voltage is missing, the issue lies in the sub-board or the main flex cable. Step 3: Inspect the Overvoltage Protection (OVP) IC If you identify a shorted power rail (e

Signal dropping, "No Service" errors, or Wi-Fi/Bluetooth failures require looking at the RF section of the blueprint. This area maps the Power Amplifier (PA) ICs, Antenna switches, and the Transceiver chip. The schematic assists in identifying which filters or supply voltages to the PA are missing or damaged.
