1. Application
This document is applied to 15" LCD TV which is
manufactured in Monitor (or TV) Factory or is produced on the
basis of this data.
2. Designation
2.1 The adjustment is according to the order which is
designated and which must be followed, according to the
plan which can be changed only on agreeing.
2.2. Power Adjustment: Free Voltage
2.3. Magnetic Field Condition: Nil.
2.4. Input signal Unit: Product Specification Standard
2.5. Reserve after operation: Above 30 Minutes
2.6. Adjustment equipments: Pattern Generator (MSPG-925L
or Equivalent), DDC Adjustment Jig equipment, SVC
remote controller
3. Main PCB check process
* Caution *
If DDC CMD don't work, please check below.
1. Enter SVC menu by SVC Remote controller (push IN-
START key)
2. Enter "ETC" menu
Check please, IIC_SW is "0" or "1".
- IIC_ SW "0": DDC Communications.(DDC2AB) in
Factory Side
- IIC_ SW "1": EDID Write/Read (DDC2B) and Factory
default(Shipping Condition).
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 pcb ass'y with JIG for ISP
2) Execute "WISP" Program.
3) Compare UOC version in BOM with version of hex file.
4) Push "Browse..." button in WISP program and select
hex file.
5) Push " Auto Execute" button
6) Occur an Error, try again and again. 2)~5)
7) After finishing ISP, Must AC Off / ON
8) Amber LED is blink during write default value in
EEPROM(24C32)
9) ALL ISP process is finished when Amber LED is off and
Blue LED is ON EEPROM(24C32) write.

ADJUSTMENT INSTRUCTION

3.3 ADC Process
"IIC_ SW" must set "0"for Auto Adjust (After ISP,
automatically set "0")
3.3.1 PC input ADC
3.3.1.1 Auto Gain/Offset Adjustment
Convert to PC in Input-source
Signal equipment displays
Output Voltage : 700 mVp-p
Impress Resolution XGA (1024 x 768 @ 60Hz)
Pattern : gray pattern that left & right is black and center is
white signal (Refer below picture).
(Model : 37, Pattern : 29 at MSPG925L)
Adjust by commanding AUTO_COLOR_ADJUST(0xF1)
0x00 0x00 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 input ADC
3.3.2.1 Auto Gain/Offset Adjustment
Convert to AV in Input-source
Signal equipment displays
Output Voltage : 700 mVp-p
Impress Resolution : CVBS 50Hz .
Pattern : gray pattern that left & right is black and center is
white signal (Refer below picture).
(Model:202, Pattern: 29 at MSPG925L)
Adjust by commanding AUTO_COLOR_ADJUST(0xF1)
0x00 0x00 instruction.
3.3.2.2 Confirmation
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
We can confirm the ADC values from "0x0C~0x11"
addresses in a page "0xA0"
