Geometry Adjustment.

Preparation:

Before starting this adjustment, adjust the horizontal and vertical static convergence.

1.Remove the deflection yoke spacer.

2.Tilt the deflection yoke as indicated in the figure below and optimise the geometry.

Tilting the DY Up and Down will balance the upper and lower pin adjustment.

Tilting the DY Left and Right will balance the H-Trap adjustment.

3.Re-install the deflection yoke spacer.
