Remember that the red and green move at 120 degree angles, so the so-called "vertical" and "horizontal" dynamic adjustments interact. "Vertical" and "horizontal" controls refer to what part of the screen is affected, not matching horizontal lines or vertical lines.

This result indicates that the vertical dynamic adjustments are wrong as well as the horizontal, in such a way to make the horizontal lines good while the vertical lines are way off. If only the "horizontal" adjustments were off, then both the vertical and horizontal lines at the right side would be mismatched. One of the red and green colors would be wrong northeast or southwest, and the other wrong northwest or southeast. (Don't ask me to remember which is which, find out by turning the static convergence.)

Do you know if the convergence coils are exactly over the internal pole pieces of the CRT? If not, you can get strange results as you try to get enough adjustment range. On the tube in my set you cannot see the pole pieces, and you need to look at the position of the convergence coils in the manual and then adjust them forward or back a little for maximum effect. Unfortunately, I haven't seen service info that actually gives measurements of the proper position.

By the way, don't bother to keep readjusting the static convergence every time you adjust dynamic. These sets do not have the diode clamps that later sets used to keep the center convergence constant. Instead, do the static center convergence first, then adjust the dynamics for equal errors from side to side (horizontal adjustments) and top to bottom (vertical adjustments) and finally readjust the static convergence. Then you can try a second finer tweak on the dynamics.
