3. Adjustment
3.1 APC
After Manual-Insult, executing APC
3.2 ISP UOC file
3.2.1 Required Equipment
- JIG for ISP
- PC that is installed with "WISP" program.
- Control + Power LED PCB Ass'y
3.2.2 ISP Sequence
1) Connect main board with JIG for ISP
2) Execute "WISP" Program.
3) Compare UOC version in BOM with version of hex file.
4) Push "Brouse..." button and select hex file.
5) Push " Auto Execute" button.
6) Occur an Error, push "Erase" button and try again and
again. 2)~5)
7) After finishing ISP, Must AC off / ON
8) Wait LED is not blink anymore
3.3 ADC Process
"IIC_ SW" must set "0"(After ISP, automatically set "0")

ADJUSTMENT INSTRUCTION

3.3.1.2 Confirmation
We confirm whether "0x00" address of EEPROM "0xA0"
is "0xAA" or not.
If "0x00" address of EEPROM "0xA0" isn't "0xAA", we
adjust once more
We can confirm the ADC values from "0x06~0x0B"
addresses in a page "0xA0"
3.3.2 AV(CVBS) Mode Adjustment
3.3.2.1 Auto Gain/Offset Adjustment
Select AV(Video) in Input menu
Signal equipment : MSPG925
Output Jack : CVBS
Output Voltage : 730 mVp-p (patt # 28 in MSPG925)
Resolution : NTSC J - 720 x 480 @59,94Hz (Model
Enter SVC menu and select "AUTO ADC"=>"AUTO
GAIN" =>
After check autocontrol of ADC, push menu key for
exiting SVC Manu.
3.3.2.2 Confirmation of adjustment process
We confirm whether "0x01" address of EEPROM
"0xA0" is "0xAA" or not.
If "0x01" address of EEPROM "0xA0" isn't "0xAA", we
adjust once more in adjustment line by adjust method
of 3.2.1.2.
We can confirm the ADC values from "0x0C~0x11"
addresses in a page "0xA0"
3.3.3 Component Mode Adjustment
3.3.3.1 Auto Gain/Offset Adjustment
Select Component in Input menu
Signal equipment : MSPG925
Output Jack : D4(Japan) or Componen(Except Japan)
Output Voltage : 700 mVp-p (patt # 8 in MSPG925)
Resolution 483/60P - 720 x 483p @59.94Hz (Model
Adjust by commanding AUTO_COLOR_ADJUST
(0xF1) 0x00 0x00 instruction.
3.3.3.2 Confirmation of adjustment process
We confirm whether "0x01" address of EEPROM
"0xA0" is "0xAA" or not.
If "0x01" address of EEPROM "0xA0" isn't "0xAA", we
adjust once more in adjustment line by adjust method
of 3.2.1.2.
We can confirm the ADC values from "0x??~0x??"
addresses in a page "0xA0"
*Caution*
If DDC CMD don't work, please check below.
1. Enter SVC menu by SVC Remote controller
2. Enter "ETC" menu
Check please, IIC_SW is "0" or "1".
- IIC_SW "0" : DDC Communications.(DDC2AB)
- IIC_SW "1" : EDID Write/Read (DDC2B) and Factory
default.
