5. Factory Adjustment
PB01A : USE EXTERNAL ADC(BCM) : using instrument.
PB02A : USE INTERNAL ADC(S7) : using internal pattern.
5-1. Auto Adjust Component
480i/1080p RGB 1080p
(1) Summary : Adjustment component 480i/1080i and RGB
1080p is Gain and Black level setting at Analog
to Digital converter, and compensate the RGB
deviation
(2) Using instrument
1) 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
0.7 V ± 0.1 V p-p correctly)
* You must make it sure its resolution and pattern cause every
instrument can have different setting
2) Adjustment method 480i Comp1, Adjust 1080p
Comp1/RGB (Factory adjustment)
O
ADC 480i Component1 adjustment -
- Check connection of Component1
- MSPG-925FA Ë Model: 209, Pattern 65
O Set Component 480i mode and 100% Horizontal
Color Bar Pattern(HozTV31Bar), then set TV set to
Component1 mode and its screen to “NORMAL”

mode
O RGB 1080p adjustment in RGB input mode
O
If you success RGB 1080p Adjust. You can see “ADC
RGB-DTV Success”
Caution : Set Volume 0 after adjustment
5-2. Use Internal ADC(S7)
- ADJ(EZ ADJUST) -> 6.ADC Calibration -> ADC
Calibration(START)
5-3. EDID(The Extended Display
Identification Data) / DDC(Display Data
Channel) download
(1) Summary
1) 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.
2) For EDID data write, we use DDC2B protocol.
5-4. Auto Download
(1) After enter Service Mode by pushing “ADJ” key,
(2) Enter EDID D/L mode.
(3) Enter “START” by pushing “OK” key.
