Summary : Adjustment component 480i/1080i and RGB

1080p is Gain and Black level setting at Analog
to Digital converter, and compensate the RGB
deviation

A

Using instrument

- 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)

<Pic.4 Adjustment pattern : 480i / 1080p 60Hz Pattern >

* You must make it sure its resolution and pattern cause every

instrument can have different setting

Adjustment method 480i Comp1, Adjust 1080p Comp1/
RGB (Factory adjustment)

1) ADC 480i Component1 adjustment

- Check connection of Component1 
- MSPG-925FA Ë Model: 209, Pattern 65

2) Set Component 480i mode and 100% Horizontal Color

Bar Pattern(HozTV31Bar), then set TV set to
Component1 mode and its screen to "NORMAL" 

3) After get the signal, wait more a second and enter the

"Ez-Adjust" with press ADJ key of Service remocon.
After then select "3.ADC 480i Comp1" with navigator
button and press "Enter". It is automatically adjustment

4) You can see "ADC Component1 Success" message

after Adjustment success

5)1 Error Messages: When its adjustment is not correct,

"ADC Component1 480i Fail" message displayed. If
component is not connection "Component1 Not
Connected", its format is not 480i then "Not Valid
Format", its signal don’t out then "Check Signal Status"
message displayed. These messages will be displayed
just a second.

6) ADC 1080p Component1 / RGB adjustment

- Check connection both of Component1 and RGB
- MSPG-925FA Ë Model: 225, Pattern 65

7) Set Component 1080p mode and 100% Horizontal Color

Bar Pattern(HozTV31Bar), then set TV set to
Component1 mode and its screen to "NORMAL" 

8) After get the signal, wait more a second and enter the

"Ez-Adjust" with press ADJ key of Service remocon.
After then select "4.ADC 1080p Comp1/RGB" with
navigator button and press "Enter". First, it is
automatically adjustment Component1.
