i noticed something else today . when the pixels/leds are set to white they appear a teal green color . what could be causing this ? it was not always like this , so ?
yes all of column 1 (left most) was dark . i actually troubleshooted the problem myself . the negative battery lead had pressed down onto a sharp solder joint causing it to ground out . with some persuasion i managed to fix it . now im back to having loads of fun with this great product . thanks
