5. ADC-Set adjustment
5-1. Synopsis
ADC-set is Gain and Black level setting at Analog to Digital
converter, and compensate the RGB deviation
5-2. Test Equipment
Service R/C, 801GF(802V, 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)'
<Fig. 1> Adjustment Mode
<Fig. 2> Adjustment Pattern: 480i/1080P 60Hz HozTV30 Bar Pattern
5-3. Adjustment
(1) ADC 480i Component1 adjustment
1) Set Component 480i mode and 100% Horizontal Color
Bar Pattern(HozTV31Bar), then set TV set to
Component1 mode and its screen to "NORMAL"
2) After get the signal, wait more a second and enter the
"Ez-Adjust" with press ADJ key of Service remocon.
After then select "2.ADC 480i Comp1" with navigator
button and press "Enter". It is automatically adjustment
3) You can see "ADC Component1 Success" message
after Adjustment success
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.
(2) ADC 1080p Component1 / RGB adjustment
- Check connection both of Component1 and RGB
- MSPG-925FA -> Model: 225, Pattern 65
1) Set Component 1080p mode and 100% Horizontal Color

Component1 mode and its screen to "NORMAL"
2) 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.
3) If adjustment is correctly finished, "ADC Component1
Success" message will be displayed. But adjustment is
not correctly finished, "ADC Component1 1080p Fail"
message will be displayed.
4) After adjustment Component1 mode, move to RGB-DTV
mode automatically and RGB adjustment start. After
RGB Adjustment successfully finished, "ADC RGB
1080P Success" message will be displayed.
5) If Adjustment doesn't success, check conditions all of
the adjustment condition and adjustment again. See
"Error Messages" sentence.

6. EDID
(The Extended Display Identification Data)
DDC
(Display Data Channel)
6-1. Summary
It is established in VESA, for communication between PC and
Monitor without order from user for building user condition. It
helps to make easily use realize "Plug and Play" function.
6-2. Write HDMI EDID data
(1) Using instruments
1) Jig. (PC Serial to D-Sub connection) for PC, DDC
adjustment.
2) S/W for DDC recording (EDID data write and read)
3) D-sub jack
4) Additional HDMI cable connection Jig.
(2) Preparing and setting.
1) Set instruments and Jig. Like fig.4), then turn on PC and
Jig.
2) Operate DDC write S/W (EDID write & read)
3) It will operate in the DOS mode.
