5.3. Adjustment of White Balance (for
Manual adjustment)
A Color analyzer(CA100+, CA210) should be used in the
calibrated ch by CS-1000
A Operate the zero-calibration of the CA100+ or CA-210, then
stick sensor to the modul adjusting.
A For manual adjustment, it is also possible by the following
sequence.
1) Select white pattern of heat-run by pressing “POWER ON”
key on remote control for adjustment then operate heat run
longer than 15 minutes.
(If not executed this step, the condition for W/B may be
different.)
2) Push “Exit” key.
3) Change to the AV mode by remote control.
4) Input external pattern (85% white pattern)
5) Push the ADJ key -> Enter “0000” (Password)
6) Select “3. W/B ADJUST”
7) Enter the W/B ADJUST Mode
8) Stick the sensor to the center of the screen and select each
items (Red/Green/Blue Gain and Offset) using D/E (CH +/-)
key on R/C.
9) Adjust R/ G/ B Gain using
F/G(VOL +/-) key on R/C.
10) Adjust three modes all (Cool / Medium / Warm) : Fix the
one of R/G/B gain and change the others
11) When adjustment is completed, Enter “COPY ALL”
12) Exit adjustment mode using EXIT key on R/C.
1 CASE
First adjust the coordinate far away from the target value(x, y).
1. x, y > target
i) Decrease the R, G.
2. x, y < target
i) First decrease the B gain,
ii) Decrease the one of the others.
3. x > target , y < target
i) First decrease B, so make y a little more than the target.
ii) Adjust x value by decreasing the R
4. x < target , y > target
i) First decrease B, so make x a little more than the target.
ii) Adjust x value by decreasing the G
5.4. Intelligent Sensor Inspection Guide
Step 1. Turn on the TV set.
Step 2. Press “EYE” button on the Adjustment remote
controller.
Step 3. Block the Intelligent Sensor module on the front C/A
about 6 seconds.
When the “Sensor Data” is lower than 20, you can see the
“OK” message
=> If it doesn’t show “OK” message, the Sensor Module is
defected one.
You have to replace that with a good one.
Step 4. After check the “OK” message come out, take out your
hand from the Sensor module.
=> Check “Sensor Data” value change from “0” to “300” or not.
If it doesn’t change the value, the sensor is also defected one.
You have to replace it.
