LCD only showing blue background, nothing else

Post by jhyland87 »

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?

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

Post a photo of your hardware and we'll see if we can spot anything.
