Panasonic LUMIX waterproof digital camer

Panasonic lumix DMC-FT1 Digital Caméra. Waterproof and shock proof. 12MP, 28mm wife. HD. In working condition. Menu/set button not working. Camera is working and everything else is working except this one button (unfortunately, it’s the menu/set button so choosing different settings becomes a problem). I don’t know if you can fix the button? Includes carry case and charger.
