Schematic Redmi 13c Extra Quality [Reliable ✮]
Allows the technician to inject voltage into a shorted rail or observe the current consumption boot-curve to identify software vs. hardware boot loops.
Supplies variable voltage to the CPU cores based on processing load.
To help find the exact diagram or hardware layout you need, please let me know:
If a power rail shows 0 ohms to ground, a shorted ceramic capacitor is the likely culprit. By referencing the schematic, look up the maximum voltage capacity of that specific rail (e.g., 1.2V for VDD_CORE). Set an external DC power supply to that exact voltage, inject current into the rail, and use freeze spray or a thermal imaging camera to identify the component that heats up. 3.

Effective diagnosis requires using multiple resources together. As experienced technicians advise, “pay attention to aligning components across schematics, block diagrams, and component placement diagrams. When necessary, combine analysis across physical boards, position diagrams, and circuit schematics”. Allows the technician to inject voltage into a
5V input from the charger passing through an OVP (Overvoltage Protection) IC.
