How to Repair the Wii Sensor Bar

With the Nintendo Wii, players use a device called the Wii-mote to manipulate on-screen gameplay. With the help of the Wii sensor bar, the Wii-mote is supposed to exactly mimic a player's movements on a TV. However, the system breaks down when both devices do not operate optimally. When the sensor bar works incorrectly, movements fail to register, leading to a frustrating gaming experience. Fixing the Wii sensor bar may simply require the removal of an obstruction, or it may require you to repair the wire connecting the sensor to the system.

Instructions

    • 1

      Check for basic problems first. Plug the sensor bar into the back of your Wii. Look for anything that may be disrupting the recommended Wii-playing environment, such as objects blocking the signal between your Wii-mote and the Wii sensor bar, infrared interference from light sources like candles, sunlight or fireplaces or radio interference from devices like wireless phones, wireless computer accessories and similar devices. Also ensure you're standing 3 to 10 feet from your TV.

      Look for damage to the wire connecting the Wii sensor to the console. Once you find it, unplug the Wii sensor before beginning any repairs.

    • 3

      Use wire cutters to completely sever the cord at the point of damage. Use wire strippers to strip both ends of rubber covering, leaving about 1 cm bare.

    • 4

      Remove the white insulating fibers on both ends until the bare wires are visible. Cut away as much fiber as you can with scissors. Use a lighter or matches to burn away the rest, so only wire remains. Take care not to burn yourself. It only takes a few seconds for the flame to burn away the coating. There should be two wires, a red one and a copper one. Keep them separate.

    • 5

      Solder the two ends together. Solder copper wire to copper wire and red wire to red wire. The wires are small, and don't need much solder.

    • 6

      Wrap the red wire and the copper wire individually with electrical tape, so they cannot touch each other. Wrap a considerable amount more of electrical tape around both wires to protect your work. Plug the wire in, and test your repairs. If the problem is solved, put the wire in a place where no one will trip on it.
