Things You'll Need
Instructions
Remove the 2 small screws on the corners of the PSP charger.
Slide off the casing, checking that none of the wires in the charger is split. If any wires are split you need to buy a new charger for your PSP, as this can't be fixed.
If the wires aren't split, apply slight pressure to press them into the soldering until they stay.
Reattach the casing. You should now have a fully working PSP charger.
If you have any more problems, then you need to look at buying a replacement charger for your PSP.
