4) MID/HIGH/LOW Mode of VIDEO
1. Input the VIDEO signal of NTSC or PAL.
2. Set the BIAS R, G and B and GAIN R, G and B of
MID, HIGH and LOW mode of W/B that are equal to
the values of corresponding items in INPUT-A.
(Altogether 18 items)
2-5. Tilt Adjustment
1. Set the Factory mode to “Device Adjust/OTHER”.
2. Adjust the stand and put the main unit into the
horizontal state. (The horizontal state of this unit is
forward tilted by
_

d
.)
3. Then, enter the X TILT value to C0.
4. Set the unit upward in vertically.
5. Then, enter the X TILT value to C1.
6. Set the unit downward in vertically.
7. Then, enter the X TILT value to C2.
8. Save the each values of C0, C1 and C2 described in
step3, 5 and 7.
2-4. White Balance Adjustment on
Servicing
2-4-1. White Balance Adjustment
Input the 10 STEP signal to INPUT-A, and observe the
chromaticity of each luminance.
When varying the chromaticity of each luminance, perform
the following adjustments.
1) MID Mode of INPUT-A
1. Input the 80 IRE FLAT FIELD signal to INPUT-A.
2. Adjust the chromaticity (x at 0.290, y at 0.320) values
by the GAIN R and B of W/B MID mode.
3. Set the INPUT signal to the 30 IRE FLAT FIELD
signal.
4. Adjust the chromaticity (x, y) to (0.290, 0.320) by the
BIAS R and B.
5. Repeat above steps 1 to 4 until the chromaticity
become the following values.
(0.290
± 0.002, 0.320 ± 0.004)
2) HIGH Mode of INPUT-A
1. Input the 80 IRE FLAT FIELD signal to INPUT-A.
2. Set the GAIN G to the integar of MID mode value
x
0.96 with the HIGH mode of the W/B.
3. Input the 30 IRE signal to INPUT-A.
4. Adjust the chromaticity (x at 0.284, y at 0.298) values
by the BIAS R and B of W/B HIGH mode.
5. Input the 80 IRE signal to INPUT-A.
6. Adjust the chromaticity (x at 0.284, y at 0.298) values
by the GAIN R and B.
7. Repeat above steps 3. to 6. until the chromaticity
become the following values.
x: 0.284 ± 0.002, y: 0.298 ± 0.004
3) LOW Mode of INPUT-A
1. Input the 80 IRE FLAT FIELD signal to INPUT-A.
2. Input the 30 IRE signal to INPUT-A.
3. Adjust the chromaticity (x at 0.313, y at 0.329) values
by the BIAS R and B of W/B LOW mode.
4. Input the 80 IRE signal to INPUT-A.
5. Adjust the chromaticity (x at 0.313, y at 0.329) values
by the GAIN G and B.
6. Repeat above steps 2 to 5 until the chromaticity
become the following values.
x: 0.313
