Preparation :
•

Before starting this adjustment, adjust the focus, horizontal
size and vertical size.

•

Receive cross hatch/dot pattern and set picture mode to
"STANDARD".

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 “DEF1 005 HTPZ” 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.)
