LCD keypad shield (dfrobot) doesn't work

floresta:
Once again... Are you sure that the program code is being downloaded into your Arduino?

Add some code to loop() that will blink an LED to find out. Make sure that it is a different LED or a different blink rate than the default 'blinky'.

Yeah, I've been testing a program code with a LED and it works perfectly. I think that the LCD is defective... =(

Thanks!!!
