I. Voltage adjustment at V
a
and V
s:
(the required values are labeled on the top right corner
of the panel)
1. Coarse adjustment
1) Unplug the output of the power panel, Apply 220VAC to mains power input.
2) Adjust V
a
Adj until voltage at V
a
reaches the required value(±1V).
3) Adjust V
s
Adj until voltage at V
s
reaches the required value(±1V).
2. Fine adjustment
1) Apply a white signal.
2) Press “M“ button to select picture menu, press ▼/▲ to select CONTRAST and
BRIGHTNESS, press ◀/▶ to change the settings to 100.
3) The set warms up about 15 min, then adjust V
a
and V
s
respectively.
Adjust V
a
Adj until voltage at V
a
reaches the required value (±0.5V).
Adjust V
s
Adj until voltage at V
s
reaches the required value (±0.5V).
II. Adjustment of White balance
i. Adjustment of White balance under RGB mode
1. Receive the 16 Gray-scale pattern,
2. Press “PICTURE” key to select STANDARD mode.
3. Adjustment of Warm temperature( 9300K)
1) Set BCUT-9K3 to 200, BGAIN-93 to 15. Use a color analyzer to measure the black
side of the screen (the scale where the luminance is about 5±1nit). Set the reading of
the color analyzer to x=0.284±0.005, y=0.299±0.005 by adjusting the value of RCUT-
9K3 and GCUT-9K3 repeatedly.
2) Then measure the white side of the screen (the scale where the luminance is
100±5nit). By changing the value of GGAIN-93 and RGAIN-93, set the reading of the
color analyzer to x=0.284±0.005, y=0.299±0.005.
3) Repeat step 1) & 2) until you can get the correct reading for both black and white
sides.
4. Adjustment of Cool temperature (11000K)
1) Set BCUT-11K to 200, BGAIN-11 to15. Use a color analyzer to measure the black side
of the screen (where the luminance is 5±1nit). By changing the value of RCUT-11K
