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. 2. 3. 4. Input the 100 IRE FLAT FIELD signal to INPUT-A. Measure the chromaticity (x, y). Input the 80 IRE FLAT FIELD signal to INPUT-A. Adjust the chromaticity (x, y) to the values measured in step 2, by the GAIN R and B of W/B MID mode. 5. Set the INPUT signal to the 30 IRE FLAT FIELD signal. 6. Adjust the chromaticity (x, y) to the values measured in step 2, by the BIAS R and B. 7. Repeat above steps 3 to 6 until the chromaticity become the following values. x ± 0.002, y ± 0.004 (The x and y are the values measured in step 2.) 2) HIGH Mode of INPUT-A 1. Input the 80 IRE FLAT FIELD signal to INPUT-A. 2. Set the GAIN G to MID mode value at �_20� with the HIGH mode of the W/B. 3. Set the BIAS R, G and B that are equal to MID mode values. (Set the BIAS R, G and B to the same as MID mode values.) 4. Input the 30 IRE signal to INPUT-A. 5. Adjust the chromaticity (x at 0.284, y at 0.298) values by the BIAS R and B of W/B HIGH mode. 6. Input the 80 IRE signal to INPUT-A. 7. Adjust the chromaticity (x at 0.284, y at 0.298) values by the GAIN R and B. 8. Repeat above steps 4. to 7. 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. Set the GAIN R that is equal to MID mode value. (Set the GAIN R to the same as MID mode value.) 3. Set the BIAS R, G and B that are equal to MID mode value. (Set the BIAS R, G and B to the same as MID mode value). 4. Input the 30 IRE signal to INPUT-A. 5. Adjust the chromaticity (x at 0.313, y at 0.329) values by the BIAS R and B of W/B LOW mode. 6. Input the 80 IRE signal to INPUT-A. 7. Adjust the chromaticity (x at 0.313, y at 0.329) values by the GAIN G and B. 8. Repeat above steps 4 to 7 until the chromaticity become the following values. x: 0.313± 0.002, y: 0.329± 0.004 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) 3. Set the GAIN G only of MID mode of W/B value at �_16� in INPUT-A.
2-5. Tilt Adjustment
n Do not put the unit upward and downward in the vertical direction for more than ten seconds. 1. 2. 3. 4. 5. 6. 7. 8. Set the Factory mode to �Device Adjust/OTHER�. Set the adjuster in contracted position. Then, enter the X TILT value to C0. Set the unit upward in vertically. Then, enter the X TILT value to C1. Set the unit downward in vertically. Then, enter the X TILT value to C2. Save the each values of C0, C1 and C2 described in step3, 5 and 7.
