Update #3: I went over the chassis and neck board looking for cracks. No cracks and good continuity. Decided to change the adjustment board for fly. Wire going from adj board to neck board was hanging on by 2 strands. Soldered that back on and no change.
Followed flowchart once more and decided to replace X303 again. It tested good before I put old one in but who knows. Picture now goes black. Calling this one done.
Thank you all that helped with this. It is greatly appreciated.
