> The other LED’s in the quadrant of the panel I mentioned are off. 


Then, there are (at least) two independent problems here.  

Problem 1:  The LEDs are not responsive, stuck in one “direction”
Problem 2:  The LEDs in the other half of the quadrant are all off.

There is no single place on the circuit that a single problem could cause both of these to happen.  First, then, try to figure out why the other quadrant is fully off.  It’s likely a soldering problem.
