Are the two neck boards you tried exactly the same revision?
I'd also check all of the wires on the neck board. They like to break very easily, and can even break inside the insulation, so you can't see that they're broken. Tone everything out with the DMM.
Also, make sure all four ground wires are good, that connect to the aluminum frame plate. There should be 2 from the neck board, one from the harness, and one for the dag spring.
You light also have issues with the HV cage or focus block pot, which is preventing the brightness (i.e., screen) pot from working. Try swapping HV cages with your good monitor.
