Things You'll Need
Instructions
Remove the battery and Memory Stick from your PSP to prevent shock or loss of data.
Remove the five screws securing the PSP faceplate. Four are located inside the battery compartment and the fifth is along the bottom edge of the device. Keep these screws in a safe place as they are small and easy to lose.
Free the analog stick by pulling straight up if it is still attached. This should require only a small amount of force.
Replace the stick by aligning the center of the plastic over the small hump of plastic, and press until it clicks. A new analog stick should pop on with no problems; if your old stick does not click when you press down, you will need to purchase a new one.
Find the plastic rectangle which houses the analog stick contacts to the right of the analog stick, and use your tweezers to pull the plastic rectangle up.
Use a small piece of clean cloth to clean the gold contacts underneath. Avoid using alcohol or alcohol swabs, because any liquid that accidentally touches the LCD screen just to the right of these contacts can cause permanent damage.
Replace the covering on the contacts with your tweezers, replace the faceplate and its screws, and return the battery to its casing. Turn on your PSP and test the analog stick.
