Quoted from jibmums:

Before I begin, this is NOT a slam on the LED/OCD board, it's a great product and I have three of them. This is just in case a fellow LED/OCD user is experiencing the same problem I just did; the solution is very simple.
I installed an LED/OCD board on my Pinbot and was very happy with it for a few days. Then an entire lamp row stopped functioning. When I reseated the connector at 1J6, another lamp row stopped functioning. I figured at this point that the male connector on my MPU had cold solder joints, so I would have to disconnect everything, pull the board, and reflow. However, simplest solution first, I figured: check the wire harnesses that connect the LED/OCD board to the MPU, which are supplied with the board. I did a little gentle tugging on the IDC connector to 1J6 and a wire popped right off. Pushed all the wires in fully with an IDC tool and voila, fully working lamps again.
Just wanted to point out this simple fix in case anyone else with an LED/OCD board in their pin encounters the same issue, before the headache of trying to figure out what the problem is or pulling any boards from their machine. Again, LED/OCD is a GREAT product, their connector wiring was just a little loose.
