This is my first contact and I need help solving a problem with my calculator's display.
My calculator's display is defective, I turned on the calculator and the screen was whitish.
I saw a topic with a problem like mine, but it didn't have a very enlightening result.
Help me please. I already opened and reopened the connections, but had no result.
If it is not possible to correct the defect, would anyone know where I can buy a new screen?
Could someone point me to a maintenance site?
I live in Brazil.
