*  ADC Adjustment(Manual)
->  Netcast4.0  (PU32A/PB32A/PK32A)  Chassis  don't  need 
ADC  adjust  process.  The ADC  value  has  been  OTP 
process. But, if you need to adjust ADC manually follow 
this method.
.
■ Using instruments
-  Adjustment  remocon,  801GF(802B,  802F,  802R)  or 
MSPG925FA pattern generator
   (It  can  output  480i/1080i  horizontal  100%  color  bar 
pattern signal, and its output level must setting 0.7V±0.1V 
p-p correctly)
(1)  Adjustment  method  480i  Comp1, Adjust  1080p  Comp1/
RGB (Factory adjustment)
(2) ADC 480i Component1 adjustment
(3) Check connection of Component1 
(4) MSPG-925FA -> Model: 209, Pattern 65
(5)  Set Component 480i mode and 100% Horizontal Color Bar 
Pattern(HozTV31Bar),  then  set  TV  set  to  Component1

(8)  Set  Component  1080p  mode  and  100%  Horizontal  Color 
Bar Pattern(HozTV31Bar), then set TV set to Component1 
mode and its screen to “NORMAL” 
(9)  After  get  each  the  signal,  enter  the  “EZ ADJUST”  status 
with  pres ADJUST  key  of  Service  remocon. After  then 
select “8. ADC Calibration” with navigator button and press 
“Enter”.
(10)  After  then  select  “ADC  Type”  and  set  value  “OTP  -> 
External” with navigator button.
(11) After then press “Start” button.
(12) You can see “ADC Component1 Success”
(13) Component1 1080p, RGB 1080p Adjust is same method.
(14)  Component  1080p Adjustment  in  Component1  input 
mode.
(15) RGB 1080p adjustment in RGB input mode.
(16)  If  you  success  RGB  1080p Adjust.  You  can  see  “ADC 
RGB-DTV Success
4.3.  EDID(The Extended Display Identification 
Data)/ DDC(Display Data Channel) 
-  It  is  a  VESA  regulation.   A  PC  or  a  MNT  will  display  an 
optimal  resolution  through  information  sharing  without  any 
necessity of user input.  It is a realization of “Plug and Play”.
->  Netcast4.0  (PU32A/PB32A/PK32A)  Chassis  don’t  need 
EDID  Download  process.  Whenever  TV  power  on,  the 
EDID data was written on inner memory.
