Don't know what model of Sharp you have but most sharps you can take keyboard apart and clean the rubber keypad magnets and the mylar circuit with warm water. let dry and reinstall. Check to see if Coke did not get in other parts. Do not use anything strong such as thinner. Rubbing alschol is good because it evaporates. Good luck

My calculator only works when it wants to. when i turn it on and press any button a 4 shows up on the screen. if i take the batteries out for a while and then put them in for a day and then try to use the calculator it seems to work but that is obviously abnormal. it hasn't worked all school year and i am pretty upset. i depend on that calculator for all my work and i need it fixed. my teacher said i could send my calculator back and have a new one but i dont know how if that is true or how to go about that.
