So I purchased this product: http://www.adafruit.com/products/1115
And im fairly certain that I put it together well. All of the python scripts within the git repo Adafruit-Raspberry-Pi-Python-Code/Adafruit_CharLCDPlate all light up the blue background, and when I push the buttons, it prints "up" "down" "select" etc etc to the terminal.. but the problem is, its just blue. theres absolutely no font at all. I played with the contrast, and nothing changed at all.
Any ideas?
LCD only showing blue background, nothing else

The contrast is the usual suspect.. it needs to be cranked most of the way to one side before the characters actually appear.
