Things You'll Need
Instructions
Make sure the power cable is plugged securely into its port in the back of the device. If this isn't the issue with the cord, then it is most likely a short in the wire. Proceed to step 2.
Cut along the length of the PSP power cable with your wire stripper. Be careful not to cut the actual wires underneath the plastic wire sheath.
Locate the short in the wire. It will be identifiable as a frayed or separated piece of wire somewhere along the cable.
Cut the cable where the short is located and then strip about an inch of sheath of off the wires at either of the cut ends.
Twist the metal wires together, making certain that they are completely connected.
Wrap electrical tape around the exposed wires, making sure that the wires are completely covered. Your PS2 cable should be fixed.
