Been A while since I did a convergence but this is basically what you do.

Disable blue and green guns so only the red is operating. On some sets there is are leads with spade connectors that you can pull off to disable the blue and green guns.

Degause your set with a degausing coil

Now with just a red screen raster, adjust the purity rings so you have a nice red screen, uniformly on the whole crt.

now re-enable your blue and green guns.

Some sets have a setup switch to disable the verticle. This switch will give you a horizontal line on the screen. Set the switch to setup position and then adjust your red blue and green gun drive controls to achieve equal intensity of all 3 guns. Then return the setup switch to normal position.

Now hook your dot generator up and tune in the set to create nice sharp dots. On the dynamic convergence board set your controls to mid point as a place to start.

The first thing to do is the static convergence. Adjust the permanent magnets on the convergence yoke so that you have perfect convergence in the center of the screen. You should have nice white dots. The 3 colors should converge nicely in the center area of the screen. There is also a blue lateral magnet that moves the blue dot left and right. The 3 magnets on the convergence yoke will move the dots at an angle of 120 degrees from each other, toward and away from, an imaginary point in the center of the crt.

Now attempt to converge dots with the dynamic convergence panel for the areas on the top, bottom, left ,and right areas of the screen using the controls on the dynamic convergence panel.

There will be some interaction of the dynamic controls. By that I mean that if you are, for example, adjusting red at the top of the screen you should also watch red dots at the bottom and elsewhere on the screen so you dont correct real nice in one area while making another area look real bad. I always tried for a good comprimise between one area and another. Then after I had a pretty good convergence, I would start all over with the static convergence again and do the whole thing over again. Usually you can improve on the first attempt after you have the controls on the dynamic board adjusted to there approximate range from the first attempt.

AS for crosshatch... Basically dots are the intersection of the crosshatch lines. The crosshatch allows you to see how linear your picture is. For convergence I woul use dots because you can see the effect of the direction you are moving the image more easily.

Like I said it has been a long time since I did a convergence, so other members please feel free to step in and add some refinments to what I have laid out here. I am sure that others have some little tricks that I have long forgotten.

Good Luck!
