Always use an Anti-Static (ESD) mat and wrist strap. Qualcomm PMICs are highly sensitive to electrostatic discharge.
Check the inputs and outputs around the secondary fast-charging IC. If the phone charges slowly or refuses to register a fast charger, inspect the surrounding resistors indicated in the schematic. Display Light / Graphic Fix
: Diagrams include labels for ICs (like the PM8150B charging IC), resistors, capacitors, and test points.

The POCO X3 (including the Standard, NFC, and Pro variants) utilizes a highly integrated motherboard. Understanding the main integrated circuits (ICs) is essential before performing hardware troubleshooting or micro-soldering.
: A technical forum containing boardview and schematic PDFs specifically for the Poco X3 (Surya) and Poco X3 NFC (Karna). Key Features of These Diagrams
A tells you how components are electrically connected (e.g., resistor R101 connects to pin 5 of IC U202). However, a BoardView (or Silkscreen) shows you exactly where those tiny components are physically located on the PCB. Using both together allows you to: Poco X3 Pro Motherboard Schematic | PDF | Chess - Scribd Always use an Anti-Static (ESD) mat and wrist strap
To access these files, you will need to utilize trusted GSM repair repositories. Always verify that the file architecture matches your phone's processor (Qualcomm Snapdragon 732G for the POCO X3 / NFC). Step-by-Step Download Instructions:

A schematic can be overwhelming at first, but it's manageable once you understand a few basics.
Turn off the power, switch your multimeter to diode mode, and place the red probe on ground. Touch the black probe to the test points indicated in the schematic to check for short circuits or open lines. Safety and Practical Precautions
A sudden black screen after a drop or water exposure might mean a damaged display connector or a blown backlight circuit. The schematic reveals which pins on the FPC connector supply power to the backlight LEDs and which handle MIPI data signals. 3. Network and Wi-Fi Signal Loss
A (or board view) is a visual, interactive representation of the physical motherboard. It shows the exact location of every component and highlights interconnected test points. When you click a pin on a bitmap viewer, it shows every other point on the board connected to that specific line.
