Most TVs when in convergence mode bring up a crosshatch pattern by which you then adjust certain points where the lines intersect horizontally then vertically.
Using a DVD wouldn't really help since the TV generates its own crosshatch pattern to adjust and doesn't display any video other then the grid.
As for adjusting the electrostatic focus yes it can only be done with the TV on.
Each color is adjusted by calling up the grid in question in service mode then adjusting the focus pot for the finest sharpest line. On the HV block you will notice 2 rows of pots one marked F for focus and one marked S for screen.
Leave the screen pots alone the 2 rows of pots will also be labelled R, G, & B for red, green, and blue.
Also another focus point is on the CRT lenses if you loosen the wingnut you can turn the lenses clockwise and counter clockwise. You adjust these by looking into the lens with the TV on and adjusting for the sharpest picture.
Like I said the red and green will be easy but the blue will be a compromise.
