it looks like you have the large, transistor-like diodes installed at D9 (which is almost right next to the chip that blew,) and that diode hasn't been stabilized yet. the legs on this diode can break due to vibration and can take out additional node boards and other stuff when it does.
[for reference, there are smaller versions also that hug the board and don't take need this reinforcement; my GB Pro has them.]
check out Stern Service Bulletin #189 for info on how to take care of this.
