Wii Balance Board Doesn't Sync with Wii Console
If you are finding that your power light on the Wii balance board keeps blinking and isn't syncing to the system, you can check a few things. First, remember it must sync to each individual game. Let the game load and be running before you sync the balance board. Only games programmed for the board will be able to use it, so look for the balance board icon on the game package. Try fresh batteries if you think the battery power may be low.
Power Problems
If a fresh set of batteries doesn't get your balance board going, double check that they are installed correctly. If they are and you still have problems, call the Nintendo line for assistance: 1-800-255-3700.
Movements Not Being Detected
The easiest correction to make is to ensure the balance board is properly placed in front of the television. If the blue power light is facing away from the television, it is positioned properly. Always check batteries for a lack of power. Lift the board and see if anything is pressing against the bottom of the board. If the carpeting or anything else is pressing on the bottom, use the foot extensions to raise the board.
