Total Assembly line process - Adjustment Preparation
■ W/B Equipment condition
CA210 : CH14, Test signal : Inner pattern (80IRE) – in case of LED back light
■ Above 5 minutes H/run in the inner pattern. (“power on” key of adjust remote control)
► The spec of color temperature and coordinate.
► CA210 : CH 14, Test signal : Inner pattern (80IRE)
- Standard color coordinate and temperature using CA-1000 (by H-R time)
▪ L14 LGD, INX Module
March to December & Global
Normal line (LB5500, LB5600)
Connecting picture of the measuring instrument (On Automatic control)
Inside PATTERN is used when W/B is controlled. Connect to auto controller or push Adjustment R/C POWER-ON -> Enter the mode of White-Balance, the pattern will come out.
Auto-control interface and directions
(1) Adjust in the place where the influx of light like floodlight around is blocked. (Illumination is less than 10ux).
(2) Adhere closely the Color Analyzer ( CA210 ) to the module less than 10cm distance, keep it with the surface of the Module and Color Analyzer’s Prove vertically.(80~100°).
(3) Aging time
- After aging start, keep the power on (no suspension of power supply) and heat-run over 5 minutes.
- Using ‘no signal’ or ‘full white pattern’ or the others, check the back light on.

Manual W/B process using adjusts Remote control.(TBD)
■ 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
(5) Adjust two modes (Medium / Warm) Fix the one of R/G/B gain to 192 (default data) and decrease the others.
(6) Adj. is completed, Exit adjust mode using “EXIT” key on Remote controller.
▪ If internal pattern is not available, use RF input. In EZ Adj. menu
8. White Balance, you can select one of 2 Test-pattern: ON, OFF. Default is inner (ON). By selecting OFF, you can adjust using RF signal in 206 Gray pattern.
CASE Cool
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
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 the model’s module from factory JIG model.
▪ Push the “IN STOP KEY” after completing the function inspection.
