SYSTEM ALIGNMENT
1. SIZE H. Size Set to fill screen at C and D. (Use
external source not internal test
pattern)
2. SIZE V. Size Set to fill Screen at A and B. (Use
external source not internal test
pattern.)
3. LIN TB LR H. Lin L-R Set equal widths CZ=ZD
4. LIN TB LR V. Lin T-B Set equal height AZ=ZB
5. LIN C H. Lin C Set box width at center equal to
average of left and right box widths
and size.
6. LIN C V. Lin C Set box heights at center equal to
average of top and bottom box widths
and size.
7. SMALL H&V Video Set the position of the external source
ARROWS Phase to be centered on the screen.
8. SKEW V. Skew Level line C-D.
9. BOW Bow V. Straighten line C-D (note that some
screen frames are curved).
10. SKEW H. Skew Line A-B edges equal distance to
screen edge.
11. BOW H. Bow Straighten Line A-B
12. KEY V. Key Set bottom edge G-H straight with
respect to screen border.
13. PIN V. Pin Set for straight bottom edge, line G-H
(corners G & H move, center B is
stable.)
14. S-ING V. ‘S’ Set for straight bottom edge, line G-H
(middle areas K & M move in opposite
direction, center B; and ends G & H are
stable).
15. W-M V. W-M Adjust for straightest line G-H (middle
areas K & M move in same direction,
center B and ends G & H are
stationary).
16. KEY H. Key Set right edge F-H straight with respect
to screen border (top and bottom move
in opposite directions; center D is
stable.)
17. PIN H. Pin Set for straight right edge, line F-H
(corner F&H move, center D is stable.)
18. S-ING H. ‘S’ Set for straight right edge, line F-H
(middle areas O & Q move opposite and
center D and ends F & H are stable.)
19. T/L KEY V. Top Key Set top edge E-F straight with respect
to screen border.
20. T/L PIN V. Top Pin Set for straight top edge, line E-F.
21. T/L S V. Left S Set for straight edge, line E-F (middle
areas J & L move opposite; center A
and ends E & F are stable).
22. T/L KEY H. Left Key Set left edge E-G straight with respect to
screen border top and bottom move in
opposite directions, center C is stable).
23. T/L PIN H. Left Pin Set for straight left edge, line E-G
(corners E & G move, center C is stable).
24. T/L S H. Left S Set for straight left edge, line E-G
(middle areas N &P move opposite; center
C and ends E & G are stable).
25. IN-KEY H. In Key Set J-K and L-M straight with respect to
line E-G, A-B, and F-H (adjust for
minimal internal keystone; top bottom
move in opposite directions; centers 3 and
4 are stable).
26. IN-PIN H. In Pin Set J-K and L-M straight (adjust for
minimal internal pincushion).
27. W-MV W-M Average error for straightest lines G-H
and E-F (middle areas K & M, and J & L
move in same direction; center B, A and
ends G & H, are stationary).
28. Touch up all controls Due to the interaction of IN-XXX con-
trols, key controls, and pin controls for
best overall convergence, it may be
necessary to ‘tweak’ the other controls.
