After getting it to work on the matrix I had hanging on the wall, I carefully took it down and framed the matrix in pvc for added support. Now all the LEDs light up white. I understand that this could be a short a cross signal and v+, but I don't understand how something so mundane as moving the matrix would cause this. Could it be a failure within a pixel causing this? Any good troubleshooting methods, short of testing each pixel individually, for figuring out where the short is at?
