debugging interactive LED display

I am 6 panels in to an 8 panel interactive LED display. I am also a newbie at this. Until Monday, I didn't know how to solder. Two of my six panels have an arrangement of 5 lights (trapezoidal pattern) that stay lit up and do not interact in any way. I haven't been able to find the problem. Any ideas? 

I also have an unrelated question. Is there an easy way to add music to the device so that when the lights are going, music is automatically triggered? 

Thanks in advance to anyone who might answer.
