GREEN HORIZONTAL SIZE ADJUSTMENT
1. Adjust with GH MSIZE so that the sizes of both ends and of
both sides of the center section of the screen are equal.
2. Adjust with GH SIZE so that the horizontal sizes of both
ends and of both sides of the center section of the screen are
equal.
3. While tracking, adjust with GH MSIZ and GH SIZE so that
the lattice intervals for the horizontal line section of the cen-
ter section of the screen are equal and so that the horizontal
size is the prescribed value.
4. If M LIN is changed when the GH MSIZ and GH SIZE ad-
justment is complete, adjust again while tracking.
 With just the H SIZE adjustment in MAIN, if there is no need
to adjust GH SIZE in SUB this can save power.
GREEN VERTICAL SIZE ADJUSTMENT
1. Adjust with GV MSIZE so that the sizes for the top and bot-
tom sections of the screen and for both sides of the center
section of the screen are equal.
2. Set the vertical size to the prescribed value with GV SIZE.
3. Adjust GV MSIZ and GV SIZE watching the vertical line at
the center section of the screen.
4. While tracking, adjust with GV MSIZ and GV SIZE so that
the lattice intervals for the vertical line section of the center
section of the screen are equal and so that the vertical size is
the regulation value.
5. If GV LIN is out of place when the GV MSIZ and GV SIZE
adjustment is complete, adjust again while tracking.
If there is no need to adjust GV SIZE in SUB with just the V
SIZE adjustment in MAIN, this can save power.

GREEN HORIZONTAL TRAPEZOIDAL DISTORTION
ADJUSTMENT
1. Adjust with GH SSKW so that the tilt of the vertical lines at
both ends of the screen is symmetrical left and right.
2. Adjust with GH KEY so that there is no tilt in the vertical
lines at both ends of the screen.
3. If there is a tilt on either the left or right after the GH KEY
adjustment, adjust while tracking.

GREEN HORIZONTAL QUATERNARY ADJUSTMENT
1. Correct the quaternary distortion with GH 4PIN.
2. While balancing, correct the quaternary distortion of both
end sections of the screen with GH 4SBOW.
3. While tracking, adjust with GH 4PIN and GH 4SBOW.

GREEN HORIZONTAL ASYMMETRICAL PIN
DISTORTION ADJUSTMENT
1. Adjust with GH MBOW so that the pin asymmetry at both
sides of the center section of screen is symmetrical.
2. Adjust with GH SBOW so that the bow at both end sections
of the screen is symmetrical left and right.
3. While tracking, adjust with GH MBOW and GH SBOW so
that the bow of vertical lines on the entire screen is sym-
metrical left and right.

GREEN HORIZONTAL SYMMETRICAL PIN DISTORTION
ADJUSTMENT
1. Adjust the pin distortion at both sides of the center section of
the screen with GH MPIN.
2. Adjust the pin distortion at both end sections of the screen
with GH PIN.
3. While tracking, adjust with GH MPIN and GH PIN so that
the PIN of vertical lines on the entire screen have no bowing.
4. If there is asymmetrical pin distortion after the GH MPIN
and GH PIN adjustments, adjust with GH MBOW and GH
SBOW while tracking.
 With just the PIN AMP adjustment in MAIN, if there is no
need to adjust GV PIN in SUB, this can save power.

GREEN VERTICAL WAVE (TERTIARY DISTORTION)
ADJUSTMENT
1. Take the screen top and bottom horizontal lines with GV
WAVE and find the secondary and quaternary waveform.
2. There is KEY distortion after the GV WAVE adjustment, so
adjust with GV WAVE and GV KEY while tracking.

GREEN VERTICAL QUATERNARY DISTORTION
ADJUSTMENT
1. Correct the quaternary distortion of the horizontal lines at
the top and bottom sections of the screen with GV 4PIN.
1) Since there is no 4SBOW for vertical correction, there will
be a slight imbalance, but adjust to eliminate the distortion
from the horizontal line at either the top or the bottom of the
screen.
2) In many cases, the horizontal lines at the top and bottom sec-
tions of the screen are not straight lines after the adjustment.
As long as the secondary distortion is mild enough that it can
be corrected with the PIN adjustment, this is OK.
GV 4PIN
GREEN VERTICAL TRAPEZOIDAL DISTORTION
ADJUSTMENT
1. Adjust with GV SSKW so that the tilt of the horizontal lines
at the top and bottom sections of the screen is symmetrical
about the center position horizontal line.
2. Adjust with GV MKEY so that there is no tilt for the line
sections at both sides of the horizontal lines at the center sec-
tion of the stream.
3. Adjust with GV KEY so that there is no tilt for the horizontal
lines at the top and bottom sections of the screen.
4. While tracking, adjust with GV MKEY and GV KEY so that
there is no tilt for the horizontal lines on the entire screen.
5. If the tilt is unbalanced after the GV MKEY and GV KEY
adjustment, adjust again with GV SSKW.

of the screen with GV MPIN.
2. Adjust with GV PIN so that the horizontal lines at the top
and bottom sections of the screen are straight lines.
3. Adjust with GV MPIN and GV PIN so that there is no curve
in the horizontal lines on the entire screen.
4. After the adjustments in Items 1-3, adjust the tracking with
GV SBOW, GV MPIN, and GV PIN.
