Examine for signs of rust or other signs that the buttons are worn out or damaged, like missing the conductive paint. Use a Q-tip, dipped in rubbing alcohol to gently clean any membrane contact that has become worn out or has conductive paint missing. Avoid rubbing too hard since this could cause damage to the conductive paint and block the button from firing when it is the button is pressed.
