A Nintendo Wii console without a working sensor bar won't be much good to you if you want to play a motion-controlled game. As of February 2013, you could pick up a replacement sensor for less than £5 from websites such as Amazon, eBay and But if you're keen to get playing and aren't willing to wait until a new sensor's delivered, there's no reason you can't carry out a quick repair job yourself.

Skill level:

  1. 1

    Contact Nintendo customer services if your sensor bar wire breaks within its warranty period. The company should pay for it to be repaired or replaced provided the problem was caused by a product fault and you didn't damage the item yourself. You'll typically invalidate your warranty if you attempt any repair before contacting Nintendo. You'll have to wait a while until you'll be able to use your console with a sensor by going down this route, but you could end up with a brand new product.

  2. 2

    Remove the damaged section of your sensor bar's wire using a wire cutter/stripper. Cut away around 2.5cm of the outer casing at the end of the wire connected to your sensor bar. Then do the same with end of the the wire connected to the plug that connects to your Wii console.

  3. 3

    Cut away the insulation fibres around the internal wires you expose at the end of both pieces of wire. Use your wire cutter/stripper to remove around 1.5cm of the insulation around the internal copper wires you've exposed.

  4. 4

    Twist the corresponding copper strands at the end of both of your pieces of wire together. Heat up your solder iron and apply a small dab of solder to the joins you've made. Do this over a heat-proof surface.

  5. 5

    Wrap electrical tape around each solder join you've made to ensure your wires don't connect and short circuit. Make sure no solder or copper wire is left exposed. Next, wrap all the internal wires you've been working on together with more tape. Position your bar in a place where it won't get knocked about. The repairs you've made could come apart if put under pressure. Connect your sensor bar and test.
