Question about Casio 76 Key Smartmedia Keyboard
Key contacts are dirty. The contacts are conductive rubber pills that get pressed against circuit traces on a board undder the keys. Clean the rubber pills AND the circuit traces with ONLY 99% isoprophyl alcohol and Q Tips. Be careful of the cables when opening the unit. There is also a slight chance that a cable has come partway loose internally. If you are uncomfortable with opening the unit and keeping track of all the screws, better take it to a repair shop.
