I have half the LEDs soldered in to my Peggy 2, and it seems to be working well. I can upload and run sketches, and everything seems to work, with the exception of row 2. It's not that Row 2 is just a little brighter than the other rows, something that I understand can go away after completion of construction. Rather, Row 2 stays entirely, brightly lit during running of the sketches with no discernable response at all to the sketch.
I understand that the transistors control the rows, and I have checked the solder joints and don't see anything obvious. Can anyone point me in a potential direction for troubleshooting? Thanks in advance,
