must use CH 9, which Matrix compensated (White, Red,
Green, Blue compensation) with CS-2100. See the
Coordination bellowed one.  

• Auto-adjustment Equipment (It needs when Auto-

adjustment  – It is availed communicate with RS-232C :
Baud rate: 115200)

• Set Baud Rate of RS-232C to 115200. It may set 115200

orignally. 

• Connect RS-232C cable to set 
• Connect HDMI cable to set 

A

RS-232C Command (Commonly apply)     

• “wb 00 00”: Start Auto-adjustment of white balance. 
• “wb 00 10”: Start Gain Adjustment (Inner pattern)  
• “jb 00 c0” :  
• …
• “wb 00 1f”: End of Adjustment 

* If it needs, offset adjustment (wb 00 20-start, wb 00 2f-

end) 

• “wb 00 ff”: End of white balance adjustment (inner pattern

White Balance Adjustment (Manual adjustment)    

• Test Equipment: CA-210 

- Using LCD color temperature, Color Analyzer (CA-210)

must use CH 9, which Matrix compensated (White, Red,
Green, Blue compensation) with CS-2100. See the
Coordination bellowed one.  

• Manual adjustment sequence is like bellowed one.  

- Turn  to  “Ez-Adjust” mode with press ADJ button of

service remocon. 

- Select  “10.Test Pattern” with CH+/- button and press

enter. Then set will go on Heat-run mode. Over 30
minutes set let on Heat-run mode. 

- Let CA-210 to zero calibration and must has gap more

10cm from center of LCD module when adjustment.  

- Press  “ADJ” button of service remocon and select

“7.White-Balance” in “Ez-Adjust” then press “

of navigation key.

(When press “ 

G 

” button then set will go to full white

mode)

- Adjust at three mode (Cool, Medium, Warm) 
- If “cool” mode 

Let B-Gain to 192 and R, G, B-Cut to 64 and then
control R, G gain adjustment High Light adjustment. 

- If “Medium” and “Warm” mode 

Let R-Gain to 192 and R, G, B-Cut to 64 and then
control G, B gain adjustment High Light adjustment. 

- All of the three mode 

Let R-Gain to 192 and R, G, B-Cut to 64 and then
