Y axis no movement

I have not had any movement in my Y axis. After a diagnostic check I discovered that it is my driver. I took the driver apart but only noticed some dirt no fuse to be blown . Capacitors and everything looks good to the eye but there is not connection on my A- with solder like the others are connected. Could this possibly be my problem or are they not supposed to be connected? I am pretty new to this so there's no stupid questions right.

Are you saying there is no solder at all on the A- pin? If so, that sounds like an issue. Can you post a picture maybe?
