3-2. CONVERGENCE

Before starting convergence adjustments:

1.Perform FOCUS, V.LIN AND V.SIZE adjustments.

2.Set BRIGHTNESS control to minimum.

3.Feed in dot pattern.

Vertical Static Convergence

1.Adjust V.STAT magnet to converge red, green and blue dots in the center of the screen (Vertical movement adjust V.STAT RV 701 to converge).

Horizontal Static Convergence

If the blue dot does not converge with the red and green dots, perform the following:

1.Move BMC magnet (a) to correct insufficient H. Static convergence.

2.Rotate BMC magnet (b) to correct insufficient V. Static convergence.

3.After adjusting the BMC magnet, repeat Beam Landing Adjustment.

2.Tilt the V.STAT magnet and adjust static convergence to open or close the V.STAT magnet.

When the V.STAT magnet is moved in the direction of arrows a and b, red, green, and blue dots move as shown below:
