I had the same problem. Both of my wii balance board had corrosion issue . End up solder back the circuit which is simple to do and works like a charm . Basically only need to solder the power link and the sync button wire. If the sync button totally out just bypass ghe button and connect to wire each and you can actually manually touch both wire for one second to sync .
