Things You'll Need
Instructions
Press various buttons on your Wii Remote to determine whether the entire controller has failed or if only the cursor aim has stopped working. If the buttons still work, the problem lies with the sensor bar. If the buttons do not work either, the problem may rest in the remote or the sync to the system.
Replace the batteries in your remote. Even if they still appear charged, they may not have enough power to work properly.
Look at the lights on the bottom of the controller. One light should remain lit steadily, indicating your player number. If no lights appear, and pressing a button causes them to flash temporarily and shut off again, you can try a resyncing process.
Turn off your console and disconnect the power for a few seconds. Reconnect it, and then turn on the system with the "Power" button on the machine itself. Once it turns on, open the front panel on the console and hold the "Sync" button in for 15 seconds. This will reset all controller syncs.
Open the battery cover on your remote and press the red "Sync" button. Quickly press and release the "Sync" button on the Wii to resync the two devices. If the player light on the controller still won't remain on or lights but will not work, you need to replace your remote. If you have a second remote, resync it as well. If it won't work either, the system itself may be defective.
Press on the sensor bar plug to ensure it remains connected to the Wii console if you've determined the remote buttons still work. Remove any obstructions between the remote and the sensor bar. Any source of heat or light near the sensor bar can distract the remote, so move them out of the way.
Move away from the TV and try moving the remote at various heights. Users can set up the sensor bar to work either above or below the television, and it will not work properly if in the wrong location. If this helps, try moving the bar to the alternate position temporarily. Enter the settings, scroll to page two and click on "Sensor Bar" to reset the location option.
View your powered sensor bar through the LCD screen on a digital camera. A working sensor bar will appear to have three glowing lights when observed in a digital picture. If any of the three lights do not appear, you need to replace your sensor bar.
