2-5. White Balance Adjustment on
Servicing
2-5-1. Signal Level Adjustment
1. Input the 95 IRE and 100 IRE signals to INPUT-A.
2. Warm up the unit at least 10 minutes.
Then enter the Service mode.
Press the keys in the following order.
“ENTER”→“ENTER”→“↑”→“↓”→“ENTER”
The message “Do you wish to enter into the
SERVICE MODE? Yes:↑ No:↓ ” will be displayed.
Select “Yes:↑”.
n
When leaving the SERVICE MODE, perform
the key operations of item 2, “Do you wish to
return to the USER MODE? Yes:↑ No:↓ ” will
be displayed. Select “Yes:↑”.
3. Set the unit in G-only mode.
4. Enter the P.DRV on the MENU screen by the DEV.
ADJ.
5. Discriminate the 95 IRE and 100 IRE by the VAMP/CONT (E) controls of the P.DRV.
6. Set the unit in Red-only mode.
7. Discriminate the 95 IRE and 100 IRE by the VAMP/SUB CON R (E) controls of the P.DRV.
8. Set the unit in Blue-only mode.
9. Discriminate the 95 IRE and 100 IRE by the VAMP/SUB CON B (E) controls of the P.DRV.
6. Adjust the chromaticity (x, y) to the values measured in
step 2. by the HIGH mode BIAS R, B of W/B.
7. Change the INPUT signal to the 80 IRE.
8. Adjust the chromaticity (x, y) to the values measured in
step 2. by the GAIN R, B.
9. Repeat above steps 5. to 8. 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) LOW Mode of INPUT-A
1. Input the 80 IRE FLAT FIELD signal to INPUT-A.
2. Set the GAIN G to HIGH mode value at “_25” with the
LOW mode of the W/B. Set GAIN to HIGH mode value
at “+15”.
3. Set the GAIN B that is equal to HIGH mode value.
4. Set the BIAS R, G and B that are equal to HIGH mode
values.
5. Measure the chromaticity (x, y).
6. Input the 30 IRE FLAT FIELD signal to INPUT-A.
7.
Adjust the chromaticity (x, y) to the values measured in step
5. by the BIAS G and B of the LOW mode of the W/B.
8. Input the 80 IRE signal to INPUT-A.
9. Adjust the chromaticity (x, y) to the values measured in
step 5. by GAIN G and B.
10. Repeat above steps 6. to 9. until the chromaticity
become the following values.
x ± 0.002, y ± 0.004 (The x and y are the values
measured in step 5.)
2-5-2. White Balance Adjustment
1) HIGH Mode of INPUT-A
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. Input the 100 IRE FLAT FIELD signal to INPUT-A.
2. Measure the chromaticity (x, y).
3. Input the 80 IRE FLAT FIELD signal to INPUT-A.
4. Adjust the chromaticity (x, y) to the values measured
in step 2. by the VAMP/SUB CON R (E) and B (E)
of the P. DRV.
5. Change the INPUT signal to the 30 IRE.
VPL-CS4/CX4

Gamma mode functions are actualized by offsetting the
output values to the Contrast and Brightness devices.
When the power plug is connected to the power line
(Standby status), all data inside the internal ROM are
written into the NVM (Nonvolatile Memory). When the
power is turned to on, required data for the current picture,
such as status memory data, etc., are selected, and they are
written into the internal RAM.
When adjustment is carried out, adjustment data are
written into the NVM automatically (items on the user
mode) or by the trigger of memory operation (items on the
service mode and factory mode), then stored them.
Adjustable items (W/B and Device Adjust) of the service
mode and factory mode are memorized into the NVM by
the memory operation. At the same time, the factory preset
(adjusted) data are all eliminated from the memory.
