Last issue with this JP is that I have one line of the DMD that is stuck on. Not always stuck on though. Just when something is displayed. For example, the brief moment that it is blank cutting from one scene to another, the line is off.

While running the DMD test the lit line moves horizontally from left to right(activating each column), once it gets to the area of where the stuck on column is, it briefly flashes one ahead of the scanning line and then once or twice behind it.

I have tried to basic re-seating of cables. will try re-seating roms next.
 
Reseat the cable on BOTH ends. If it works you might consider reflowing the solder on both headers and/or replacing the ribbon cable.
 
If you have another pin, borrrow the ribbon cable and try it. I'd reflow the headers on both boards as they are known to develop cold solder joints.
