No, no, no. Not back and forth just the axis. Back and forth will affect purity and is covered in the service manual as such.

Up and down, left and right after removing the bungs.

Have a look at "Sony Trinitron TV Color Purity & Convergence repairs" on YouTube which will walk you through the adjustment and illustrate the changes when making them on a domestic Sony.
