(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
mode and its screen to “NORMAL” 

(6) Check connection both of Component1 and RGB
(7) MSPG-925FA Ë Model: 225, Pattern 65
(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,  wait  more  a  second  and  enter

the  “IN-START”  with  press  IN-START  key  of  Service
remocon.  After  then  select  “7.  External  ADC”  with
navigator button and press “Enter”. 

(10) After  then  select  “23.  Auto  ADC”  and  set  value  “On  ->

Off” with navigator button.

(11) Press IN-START Key again.
(12) Select  “External  ADC”  with  navigator  button  and  press

“Enter”

(13) After  Then  Press  key  of  Service  remocon  “Right

Arrow(VOL+)”

(14) You can see “ADC Component1 Success”
(15) Component1 1080p, RGB 1080p Adjust is same method.
(16) Component  1080p  Adjustment  in  Component1  input

mode

(17) RGB 1080p adjustment in RGB input mode
(18) If  you  success  RGB  1080p  Adjust.  You  can  see  “ADC

RGB-DTV Success”

Depend on situation, Step can be changed.
