Just to make sure, have you already seen text on the display or is it the first time you power it up.
Because if it is, there is a little pot meter on the back of the display and you have to rotate it to change the contrast of the letters.
The first time if tried my lcd i couldn't see any text. But when I changed the pot value a bit I could read the text.
This is probably not the problem, but just to be sure :p
