4-2. Manual ADC Process using Service 
Remocon
After  enter  Service  Mode  by  pushing  “ADJ”  key,  execute
“ADC Adjust” by pushing “
G
” key at “0. ADC CALIBRATION”. 
4-3. Confirmation
(1) We  confirm  whether  “0xBF(480i)/0xC8(1080i)”  address  of
EEPROM “0xA2” is “0xAA” or not. 
(2) If  “0xBF(480i)/0xC8(1080i)”  address  of  EEPROM  “0xA2”
isn’t “0xAA”, we adjust once more
(3) We can confirm the ADC values from “0xB9 ~ 0xBE(480i) /
0xC2 ~ (1080i)” addresses in a page “0xA2”

same  as  Vs  voltage  which  on  label  of  panel  left/top    (
deviation ; ±0.5V)
(2) Va adjustment (refer fig.1)                                               
1) After receiving 100% Full White Pattern, HEAT RUN.
2) Connect  +  terminal  of  D.M.M.  to  Va  pin  of
P812(42”:P811),  connect  -terminal  to  GND  pin  of
P811(42”:P812).
3) After  turning  VR502,voltage  of  D.M.M  adjustment  as
same  as  Va  voltage  which  on  label  of  panel  left/top
(deviation; ±0.5V)

8. Adjustment of White Balance
Caution: Press the POWER ON KEY on R/C before W/B adjustment.
8-1. Test Equipment
- Color Analyzer(CS-1000, CA-100+(CH.10), CA-210(CH.10) )
[ Please adjust CA-100+ / CA-210 by CS-1000 before measuring
--> You should use Channel 10 which is Matrix compensated
(White, Red, Green, Blue revised) by CS-1000 and adjust
in accordance with White balance adjustment coordinate.

8-2. Connecting Picture of the Measuring 
Instrument
(On Automatic control )
Inside PATTERN is used when W/B is controlled. Connect to
auto controller or push control R/C ADJ Key‡ Enter the mode
of White-Balance, the pattern will come out.
8-3. 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) In  case  of  PDP:  Measure  and  adjust  after  sticking  the
Color  Analyzer  (CA-100+,  CA210  )  to  the  side  of  the
module. 
In  case  of  LCD:  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  
1)  After  aging  start,  keep  the  power  on  (no  suspension  of
power supply) and heat-run over 5 minutes.
2) In case of PDP, keep white pattern using inside pattern.
3) In case of LCD, using ’no signal’ or ‘full white pattern’ or
the others, check the back light on.
