Glad to see you have the sync back. From the first photo I could tell the sync was off because the rainbow was horiz and not vert. The further off the freq is the more lines you'll have. Ground the grid on the reactance tube. As you adjust, you may go through the horiz then vert. scenario several times. Your best adjustment will give the least number of, but widest (floating) vertical bars

Next thing you need to do is to get a halfway decent convergence on the set. You'll be amazed with your progress.
