How to Fix Toshiba PA3237U-1ACA AC Adapter power cord wire

If one of the wires of your Toshiba PA3237U-1ACA AC Adapter laptop power cord is damaged, you may be able to repair it yourself. Before attempting any repair, however, check your manufacturer's or extended warranty on your laptop. Repairing the Toshiba AC Adapter power supply wire yourself will definitely void any warranty on the laptop ac adapter power supply.

Here is the brief Instructions on how to Fix Toshiba PA3237U-1ACA AC Adapter wire:

Cut out the entire damaged portion of wire from your Toshiba PA3237U-1ACA AC Adapter power supply, cutting straight across both wires on either side of the damage to remove a complete section of cord. If the wires inside the remaining Toshiba AC Adapter cord look blackened, cut out more until you see bright copper or aluminum wire.

Slice between the two wires on the cord gently to separate the insulation that holds them together. Be careful not to damage the individual insulation on each Toshiba PA3237U-1ACA AC Adapter wire. Cut off the outer insulation surrounding the last inch of wire on each side of the cut. Strip the individual wire insulation off the last 1/4-inch of each wire on both sides of the cut. Cut a 2 1/2-inch-long piece of shrink tube big enough to fit over the outer insulation loosely, and slip it over the ends of the longer portion of wire, sliding it down the cord until it is out of your way for working with the laptop ac adapters wires.
Place one stripped end of the Toshiba PA3237U-1ACA AC Adapter wire all the way into your barrel connector, until the insulation meets the place where the barrel narrows and the bare wire tips are at the center of the connector. Squeeze the connector tightly shut with a crimping tool. Find the Toshiba AC Adapter wire that your first wire connected to before you cut out the damaged section and place it into the other end of the crimp. Squeeze the crimp shut.

Pull firmly on both Toshiba PA3237U-1ACA AC Adapter wires. If one comes out, remove the crimp from both (you may have to trim back your wires to cut it off) and start with a fresh crimp.Repeat the process for the second laptop ac adapter wire. Slide the shrink tube up over the connection until it is completely covered. Apply heat to the shrink tube with a heat gun until it shrinks to fit snugly against the Toshiba PA3237U-1ACA AC Adapter wires and connectors.
