SET-UP ADJUSTMENTS

The following adjustments should be made when a

Perform the adjustments in order as follows:

complete realignment is required or a new picture

1.

Beam Landing

tube is installed.

 

2.

Convergence

These adjustments should be performed with rated

3.

Focus

power supply voltage unless otherwise noted.

4.

Screen (G2)/White Balance

The controls and switch should be set as follows

Note: Test Equipment Required

unless otherwise noted:

 

1.

Color Bar Pattern Generator

 

 

PICTURE control ................. normal

 

2.

Degausser

 

 

3.

3-1. BEAM LANDING

Preparation:

Input a white pattern signal.

Face the picture tube in a East or West direction to reduce the influence of geomagnetism.

NOTE: Do not use the hand degausser because it magnetizes the CRT .

1.Input white pattern from pattern generator.

2.Loosen the deflection yoke mounting screw, and set the purity control to the center as shown below:

3.Input green pattern from pattern generator.

4.Move the deflection yoke backward, and adjust with the purity control so that green is in the center and red and blue are even on both sides.

G

5.Move the deflection yoke forward, and adjust so that the entire screen becomes green.

6.Switch over the raster signal to red and blue and confirm the condition.

7.When the position of the deflection yoke is determined, tighten it with the deflection yoke mounting screw.

8.When landing at the corner is not right, adjust by using the disk magnets.
