If the Coaxial Is Broken off on My TV How Do I Fix It?

By David Lipscomb

A television with a broken coaxial cable connector prevents cable box or antenna signals from entering the set. Proper removal and replacement of this coaxial component is necessary in order to regain the audio and video input for the television. If you have basic electrical wiring knowledge and few tools, you can undertake this repair, since the process is fairly straightforward and inexpensive. In most cases, removing and replacing a broken coaxial connector does not require contacting a repairman.

Things You'll Need

  • Needle nose pliers
  • Wire cutters
  • Coaxial strip tool
  • Coaxial compression connector
  • Coaxial compression crimp tool

Step 1

Unplug the television from the electrical outlet. Locate for the broken coaxial connector protruding from the rear of the set.

Step 2

Turn the broken connector counterclockwise using the needle nose pliers. Unscrew it by hand when it loosens sufficiently.

Step 3

Cut 1/2-inch of insulation from the cable line. Make sure the end of the cut is as straight as possible.

Step 4

Set the cable into the stripper tool, so that the end of the cable presses against the stopper on the tool.

Step 5

Grasp the handles of the tool and rotate it three or four times in both directions. Pull off the unwanted outer jacket.

Step 6

Separate the braided inner shield by hand and fold it back so it is evenly distributed around the outer cable jacket. This reveals the inner white plastic dielectric insulation.

Step 7

Set the exposed white plastic dielectric insulation into the strip tool. Spin the tool around the insulation jacket, removing half of its length to expose the copper wire.

Step 8

Push the new connector onto the end of the cable so that the copper wire goes through the center of the connector. Make sure the white dielectric insulation is flush with the inner flange of the connector.

Step 9

Place the new connector into the crimp tool. Squeeze the handles, forcing the plastic and metal components of the compression connector together with a snap.

Step 10

Insert the end of the cable onto the coaxial input on the television and screw the threaded end onto the socket by hand to tighten the connection.
