Set the PICTURE 70% and BRIGHTNESS 0%.
•
Cross hatch / Dot pattern.
(1) Horizontal and Vertical Static Convergence
1. (Moving horizontally), adjust the H.STAT control so that
the red, green and blue dots are on top of each other at the
center of the screen.
2. (Moving vertically), adjust the V.STAT magnet so that the
red, green and blue dots are on top of each other at the
center of the screen.
3. Adjust Horizontal Trapezoid with “DAC 04 HTR” in
Service Mode to make H-Trapezoid distortion best.
4. If the H.STAT variable resistor cannot bring the red, green
and blue dots together at the center of the screen, adjust
the horizontal convergence with the H.STAT variable
resistor and the V.STAT magnet in the manner given
below.
(In this case, the H.STAT variable resistor and the V.STAT
magnet influence each other, so be sure to perform
adjustments while tracking.)
