Vertical position adjustment
1. Set the item [H-V
A
[V-HET].
2. Adjust with the remote control buttons [VOL +/-] to a narrower
vertical amplitude and confirm the vertical center of the image
B
(crosshatch pattern).
3. Set to the item [V-POS].
A=B
4. Adjust with the remote control buttons [VOL +/-] so that the vertical
center of the crosshatch pattern comes to the center of the screen.

5. Set to the item [V-HET], set to "3F", and adjust by turning R464 so
that the number of horizontal lines of the crosshatch pattern
becomes 5.5 lines at the top and at the bottom.

• Caution items
For adjustment of V-HET, keep "3F" fixed and adjust by turning
R464. However, when adjustment of the vertical amplitude with
R464 is not possible, adjust the value for [V-HET] in the range
from 3A to 44 (hexadecimal).

Vertical linearity adjustment
6. Set to the item [V-LIN].

7. Adjust with the remote control buttons [VOL +/-] so that the interval
between the lines of the upper half and the lower half of the
crosshatch pattern becomes uniform.
C
Vertical S-shape compensation adjustment
8. Set to the item [V-SCR].
9. Adjust with the remote control buttons [VOL +/-] so that the grid
size of the crosshatch pattern becomes the same at the center and
at the top and the bottom.
10. Perform the adjustments 6. to 9. alternately until the line interval
between the straight lines becomes uniform.
