If you want to learn TV sweep alignment it's best to get some old servicing text books, or a sweep alignment generator operators manual that explains the process. But before go there you need to have a fairly solid understanding of how the video and audio signals travel through the various circuits. Without that basic understanding you're really at a loss as to how the equipment gets connected into circuit and what you're actually looking at on the scope display.
I had TV servicing classes back in the early 1980's and I don't recall us ever doing video IF alignment. I do recall our textbook for that class had an endorsement on the Sencor visual alignment process, but it never went into any detail on a practical way to utilize it. Even the manual for those units seems to tip toe around that specific application. IMO those units are more less a bells and whistles version of a video test pattern(to see what the video IF response of the set in question looks like), but not so friendly when it comes to adjusting the video response curve.
