High-definition multimedia interface cables, or HDMI, carry delicate signals. Contained within the outer jacket of each HDMI cable are multiple individual conductors, carrying anything from audio and video to a small 5-volt charge. This similarity to Ethernet cables means that, in the event of a nick or cut to an HDMI cable, the same repair procedure may be followed. The crimping materials needed to complete the project are available at any major home improvement store.
- Skill level:
Things you need
- Ethernet crimp joiners
- Crimp tool
- Sharp utility knife
- Electrical tape
Cut around the location of the nick or cut with a sharp utility knife, so that there is no outer jacketing surrounding the cut. Take care to only cut out the outer jacket so as to not damage the inner conductors.
Take the utility knife and carefully remove 2-3 millimetres of insulation on the damaged inner conductor.
Twist the two bare wire ends together. Set the twist into the open end of the crimp. Place this end into the crimp tool, and squeeze firmly. Note that you may have to bend the cable slightly to get the two halves to join comfortably.
Wrap the entire point of repair with a few passes of electrical tape. Avoid placing undue stress on this cable after the repair.
