If you are facing one of the following scenarios, a schematic is indispensable:
Each analog stick consists of two independent 10kΩ potentiometers. 3.3V Reference Voltage (VCC) Pin 2: Wiper Pin (Analog Output Voltage to MCU) Pin 3: Ground (GND)

Before looking at a schematic, it helps to understand the main components of the controller's printed circuit board (PCB):
Note: While the controller may turn on with the capacitor completely removed, it is highly recommended to solder a replacement SMD capacitor of equivalent capacitance (usually 10uF or 0.1uF depending on the schematic rail) to maintain wireless signal stability. 5.
