GREEN VERTICAL QUATERNARY DISTORTION ADJUSTMENT

1.Correct the quaternary distortion of the horizontal lines at the top and bottom sections of the screen with GV 4PIN.

1)Since there is no 4SBOW for vertical correction, there will be a slight imbalance, but adjust to eliminate the distortion from the horizontal line at either the top or the bottom of the screen.

2)In many cases, the horizontal lines at the top and bottom sec- tions of the screen are not straight lines after the adjustment. As long as the secondary distortion is mild enough that it can be corrected with the PIN adjustment, this is OK.
