A visual map of the actual physical motherboard. It helps you locate exactly where a specific resistor or chip is positioned on the front or back of the board.
For a successful repair, you will need the phone's user manual (for safe handling and general part identification), and the complete service manual or schematic diagram, which contains the PCB diagram with IC names and descriptions. You may also find support community forums, like those on XDA Developers or iFixit, helpful for additional advice.
: Specific measurement points for checking if the 18-Watt fast-charging circuit is functioning correctly. Connectivity Traces Visual and Practical Guides Video Schematics Playlist :
Traces from the SIM tray connect to the CPU or a dedicated card detection IC.
Locate USB_D+ and USB_D- . These lines run through small EMI filters directly to the CPU. Torn filters or blown ESD diodes here will stop fast charging and data transfer entirely. Display and Backlight Architecture
: Once the repair is complete, reassemble the phone in the reverse order of disassembly, reconnect the battery at the very end.
Measure impedance (diode mode) on critical FPC connectors (LCD, Camera, Battery) to detect shorted circuits. Conclusion
