This professional hardware repair guide covers all motherboard input and output voltages (VBUS, VPH_PWR, PMIC) to fix no-power issues.In this video, we perform a deep-dive diagnosis of the Redmi Note 14 Pro 5G power sequence. If your device is stuck on a black screen or shows 0.0mA on the DC Power Supply, follow these exact test points to find the short circuit or faulty IC using a multimeter. Technical Troubleshooting Steps:Input Stage: Check VBUS (5.0V) at the charging connector and OVP IC.Battery Rail: Measure VBAT (3.7V - 4.4V) at the battery connector.Main Power: Test VPH_PWR (3.7V) after the DC-to-DC Charging IC.PMIC Outputs (LDO & Buck):VDD_CPU: 0.8V - 1.2V (Booting rail)VDD_SOC: 0.9VLDO 1.8V: Always ON rail for Power Key sensing.Clock & Reset: Verify 19.2MHz Crystal Oscillator and Power Key high-to-low trigger.
