Hitachi 32HE2200 Wi-Fi doesn't work but LAN works. Nothing happens when trying to scan wireless networks, it says please wait and then doesn't do anything. My other TV is working so I don't think there's anything wrong with my connection. I tried a factory reset and a using a working Wi-Fi board 17WFM21 with the same spec as the original but it still doesn't work. Any help would be welcome.
