: For common hardware failures (e.g., charging, audio, or Wi-Fi), technicians often use "service ways"
Often points to a bootloop, corrupted EMMC/UFS storage, or a missing secondary voltage rail (e.g., 1.2V RAM voltage). Step 3: Measure the Power Button Line

When examining the , you will typically see the following critical zones, usually divided into Top (Layer 1) and Bottom (Layer 2) sides of the mainboard. 1. Power Management Unit (PMIC) Section
Responsible for 4G LTE, Wi-Fi, Bluetooth, and GPS. This section contains transceivers, power amplifiers, and antenna switch modules. RF schematics are highly detailed, showing signal paths that require precise impedance matching. Display and Touch Control (OLED Circuit)
Check the capacitors, resistors, and coils associated with that rail for open circuits or shorts to ground. Whether you're a repair technician, DIY enthusiast, or
Use a multimeter to probe the capacitors indicated in the diagram.
The S9 features multiple high-definition microphones and stereo speakers driven by dedicated audio codecs. The schematic identifies the exact series resistors and decoupling capacitors that can break during drop impacts.
