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 Æ EZ adjust using adj. R/C Æ 7. White-Balance then press the cursor to the right (KEY ). 

(When KEY( ) is pressed 216 Gray internal pattern will be displayed) 

4) One of R Gain / G Gain / B Gain should be fixed at 192, and the rest will be lowered to meet the desired value. 
5) Adj. is performed in COOL, MEDIUM, WARM 3 modes of color temperature. 
   
▪ If internal pattern is not available, use RF input. In EZ Adj. menu 7.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 216 Gray pattern. 

 
▪ Adj. condition and cautionary items 
1) Lighting condition in surrounding area 

Surrounding lighting should be lower 10 lux. Try to isolate adj. area into dark surrounding. 

2) Probe location 

- PDP: Color Analyzer (CA-100, CA-100+, CA210) probe should be firmly attached to the Module 
- LCD: Color Analyzer (CA-210) probe should be within 10cm and perpendicular of the module surface (80°~ 100°) 

3) Aging time 

- After Aging Start, Keep the Power ON status during 5 Minutes. 

- In case of LCD, Back-light on should be checked using no signal or Full-white pattern.
