LCD 16x2 onyl one line works (stucked on basic example)

Hey guys:

I am starting to have fun with Arduino one and LCDs (16x2 hd44780), I did as told here http://arduino.cc/en/Tutorial/LiquidCrystal.

Got the LCD to turn on, show blacks blocks, but when I upload the hello world example, y got nothing.

CAn Anyone help me debug?

That is a sign of wrong/bad wiring, so... check your wiring diagram.

We will need a better picture in order to do any real debugging of your connections. We have to be able to see both ends of each wire and be able to tell where they are connected.
