Hi alung92,

I already test your code and it is working. Could you try to adjust the LCD contrast (variable resistor)? If still problem, you can contact the Technical Support by filling up this form (link).

If you already upload the code successfully to Arduino, it should be a character displayed on the LCD.

But if the LCD still blank, probably the SHIELD-LCD is defect. Please contact the Technical Support by filling up this form (link).
