Jdm-040: Schematic !!better!!

The most repaired sections of the JDM-040 schematic are the analog stick and trigger circuits. Potentiometers:

: If you desolder the analog sticks, the LSX and LSY lines become "floating," meaning they have no defined voltage. This causes the controller to register chaotic, random movements until new pots are installed. jdm-040 schematic

The JDM-040 uses dedicated H-bridge driver ICs (often labelled DRV2605 clones or custom Sony mark codes) to drive the voice coil actuators. The schematic shows two separate circuits: one for the left haptic motor and one for the right. A common failure on the JDM-040 is a blown capacitor on the rail, which the schematic identifies as a 10µF 6.3V ceramic cap. The most repaired sections of the JDM-040 schematic
