My wii fit board is not recognized by wii. What could be wrong? It has been at least a year since last usage. Batteries were corroding and I cleaned this as best as I could. Although wii fit board does turn on but it is not been recognized by wii. I have tried the in sync buttons on the system and the wii board. I have even tried resetting the game multiple times. I am not electronically smart and unsure what else to do. Are batteries responsible for my wii fit board not been recognized by wii? Please advice appropriately. Thanks.
