2). Convergence Adjustment

Preparation:

Before attempting any convergence adjustment,the TV should be operated for at

least 15 minutes.

2.1 Center convergence adjustment

2.1.1 Receive dot pattern.

2.1.2 Adjust the brightness/contrast controls to obtain a sharp picture.

2.1.3 Adjust two tabs of the 4-pole magnet to change the angle between them and red

and blue vertical lines are superimposed each on the center of the screen.

2.1.4 Turn both tabs at the same time keeping the angle constant to superimpose red

and blue horizontal lines on the center of the screen.

2.1.5 Adjust two tabs of the 6-pole magnet to superimpose red/blue lines and green

line.

2.1.6 Remember red and blue movement.Repeat steps 2.13~2.15 until optimal

convergence is obtained.

2.2 Circumference convergence adjustment

2.2.1 Loosen the clamp screw holding the deflection yoke assembly and allow it

tilting.

2.2.2 Temporarily put the first wedge between the picture tube and deflection yoke

assembly. Move front of the deflection yoke up or down to obtain better

convergence in circumference. Push the mounted wedge in to fix the yoke

temporarily.

2.2.3 Put the second wedge into bottom.

2.2.4 Move front of the deflection yoke to the left or right to obtain better

convergence in circumference.

2.2.5 Fix the deflection yoke position and put the third wedge in either upper space.

Fasten the deflection yoke assembly on the picture tube.

2.2.6 Detach the temporarily mounted wedge and put it in either upper space. Fasten
