Hi,
Today i recieved the 32x16 RGB Matrix and connected it how the manual tells me to
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.
Please Help!

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

Re: 32x16 RGB Matrix
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)?

Re: 32x16 RGB Matrix
Did you use external power for led matrix?

Re: 32x16 RGB Matrix
