Blue was the toughest of the three, taking over 15 minutes to get the best possible result. Focusing the CRTs was not at all unlike getting a new pair of glasses with a new prescription. Everything was noticeably clearer and sharper. More on that later. Next, Robert got to work touching up the geometry and convergence.
Geometry refers to shapes being correctly rendered by a display.
In other words, if a circle is portrayed on the screen it is a shown as a round circle, not an elliptical egg shape resembling a circle. Robert also checked to make sure that my display was showing as much picture area as possible without retracing or flagging. My set was within this range and required no adjustment. This is another adjustment that can be touched up via the main menu, but ultimately must be done in the service menu to get the best result. This also made using the crosshatch pattern on VE, this time with all three CRTs firing.
