mode. (Warm, Medium, Cool)
6) Remove probe and RS-232C cable to complete adj.
▪  W/B Adj. must begin as start command “wb 00 00” , and 
finish as end command “wb 00 ff”, and Adj. offset if need.
(2) Manual adjustment. method
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  10  cm  of  the 
surface.
3)  Press ADJ key → EZ adjust using adj. R/C → 7. White-
Balance then press the cursor to the right(key ►).
(When right 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)  Adjustment  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,
