It is a little hard for me to tell from the picture. I kind of question the two resistors on the right. And two of the resistors are touching but I think them touching are probably not the cause unless the current travels so I would try to shove a thin piece of paper between them to see if it operates any differently. I would need another picture angle because the picture doesn't show the other side of the chip. Maybe a horizontal closeup between the matrix and the board too to see what it reveals? I know it is hard to get good quality pictures of stuff that small but pictures in the daytime probably provide the best possible light.
Adafruit posted this soldering guide:http://learn.adafruit.com/adafruit-guid ... n-problems
Can you identify any soldering problems from the guide?
If someone was desperate, I could offer to solder one for free with lead free solder, test it and make sure it works if someone was to send me one. I found my Panavise Jr and I can possibly post a picture of my work.
