The lightbar flex circuit connects directly to the mainboard via a top-mounted connector rather than wrapping around the housing.
The outer shell displays CUH-ZCT2 or CUH-ZCT2U. jdm-040 schematic
Another extensive analysis from October 2019 provides more specific component data for a JDM-040 that had lost USB sync and charging capability. The user identified three missing components, and the community provided these values: The lightbar flex circuit connects directly to the
Button presses are registered when a conductive rubber pad bridges two exposed copper traces on the flexible circuit film. The user identified three missing components, and the
If the controller fails to charge, the Power Management IC (PMIC) may be faulty. Some modders use an alternative TP4056 charging module as a workaround if the original IC is irreparable.
When troubleshooting, use a multimeter to check continuity between the USB connector and the mainboard to ensure power is reaching the battery.
