Hi,

My Arduino Uno R2 but i have one problem: the blue led's doesn't work. I have uploaded the
Plasma example code to the arduino, the red and green lights work but the blue one wont.

I also used other example codes. But by the text scrolling sketch the display does nothing.

Try swapping the wires that connect to the red and blue output bits (there's two of each, as I recall). Do the blue LEDs now light up (instead of red)?

Did you use external power for led matrix?
