■ Color analyzer(CA100+, CA210) should be used in the
calibrated ch by CS-1000
■ Operate the zero-calibration of the CA100+ or CA-210, then
stick sensor to the module when adjusting.
■ After enter Service Mode by pushing "ADJ" key,
■Enter White Balance by pushing "►" key at "8. White Balance".
■ For manual adjustment, it is also possible by the following
sequence.
1) Set TV in Adj. mode using POWER ON
2) Zero Calibrate the probe of Color Analyzer, then place it on the
center of LCD module within 10cm of the surface
3) Press ADJ key -> EZ adjust using adj. R/C -> 8. White-Balance
then press the cursor to the right (KEY►). When KEY(►) is
pressed 206 Gray internal pattern will be displayed.
4) Adjust Cool modes
(i). Fix the one of R/G/B gain to 192 (default data) and
decrease the others
(If G gain is adjusted over 172 and R and B gain less than
192, increase G gain to 192 and increase R gain and B gain
same amount of increasing G gain.)
(ii). If G gain is less than 172,
Increase G gain by up to 172, and then increase R gain and
G gain same amount of increasing G gain.
(iii). If R gain or B gain is over 255,
Readjust G gain less than 172, Conform to R gain is 255 or
B gain is 255

192
※ CASE Cool
192
First adjust the coordinate far away from the target value(x, y).
192
1) x, y > target
i) Decrease the R, G.
128
2) x, y < target
128
i) First decrease the B gain,
128
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
How to adjust
1) If G gain is adjusted over 172 and R gain and B gain less
than 192 , Adjust is O.K.
2) If G gain is less than 172 , increase G gain by up to 172, and
then increase R gain and B gain same amount of increasing
G gain.
3) If R gain or B gain is over 255 , Readjust G gain less than
172, Conform to R gain is 255 or B gain is 255
※ CASE Medium / Warm
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
▪ After You finish all adjustments, Press "In-start" button and
compare Tool option and Area option value with its BOM, if it is
correctly same then unplug the AC cable. If it is not same, then
correct it same with BOM and unplug AC cable. For correct it to
