If you’re having trouble changing the light on your PlayStation 4 controller, there are a few things you can do. First, make sure that the light is actually broken. If it’s not, try these steps:

  1. Open up your PlayStation 4 system and remove the back cover.
  2. Look for a small screw near the top-right corner of the system board. Remove this screw with a Phillips head screwdriver.
  3. Locate and remove two screws from the top of the controller PCB (the circuit board that holds all of the electronics). Once these screws are removed, gently pull off the PCB from around the light sensor and buttons.
  4. Replace the PCB, screws, and sensor in reverse order and reattach the back cover to your PS4 system. ..
