horizontal and vertical line.
8. Adjust Blue horizontal line to convergence with
green horizontal line and blue vertical line 3/4" to
left of green vertical line.
9. Press
PIP

lines.
5. Adjust horizontal controls to obtain straight vertical
lines.
6. Repeat steps 2-5, as necessary, to achieve best
