2. Designation
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) Power Adjustment : Free Voltage
3) Magnetic Field Condition : Nil.
4) Input signal Unit : Product Specification Standard
5) Reserve after operation : Above 30 Minutes 
6) Adjustment equipments: Color Analyzer(CA-210 or CA-
110), Pattern Generator (MSPG-925L or Equivalent), DDC
Adjustment Jig equipment, SVC remote controller
3. Main PCB check process
3.1. Download
1) Execute ISP program “Mstar ISP Utility” and then click
“Config” tab.
2) Set as below, and check the following tabs.
Port type - Choose the your port type, Normally “LPT1” or
“LPT2.
Speed - Choose the speed from 70 to 99.
JIG - Choose the your JIG type, Normally “Mstar” or “LGE”.

* APC - After Manual-Insert, executing APC
3.2. ADC Process
(1) PC input ADC
1) Auto RGB Gain/Offset Adjustment
(a) Convert to PC in Input-source
(b) Signal equipment displays.
Output Voltage : 730 mVp-p
Impress Resolution XGA(1024x768@60Hz)
Pattern:gray pattern that left & right is black and
center is white signal(Refer below picture)
(Model:60, Pattern:28 at MSPG925L)
(c) Adjust by commanding AUTO_COLOR_ADJUST
(0xF1) 0x00 0x02 instruction.
2) Confirmation
(a) We confirm whether “0x8C” address of EEPROM
“0xB4” is “0xAA” or not.
(b) If “0x8C” address of EEPROM “0xB4” isn’t “0xAA”,
we adjust once more.
(c) We can confirm the ADC values from “0x00~0x05”
addresses in a page “0xB4”.
3.3. Function Check
: Check Input and Signal items (cf. work instruction)
(1) TV

(2)15 Pin D-Sub Jack is connected to the signal of Pattern
Generator.
4.2. Confirm color coordinate of AV2
(1) Set Input to AV2.
(2) Input signal : CVBS, PAL @ 50Hz
Full White 216/255 gray level (85 IRE, Model : 202 
Patter : 78 at MSPG925L)
(3) Set PSM : Dynamic / CSM : Cool
(4) Confirm whether x=0.276±0.03, y=0.283±0.03, y≥0.250 or
not.
4.3. Other quality
(1) Confirm that each items satisfy under standard condition
that was written product spec..
(2) Confirm Video and Sound at each source.
1) AV
(a) Select input AV1 and check whether picture is
displayed or not. - Check whether SCART output
picture is displayed or not.
(b) Select input AV2(S-video) and check whether picture
is displayed or not.
(c) Select input AV2(CVBS) and check whether picture
is displayed or not.
2) TV : Select input TV and check below item.(In Gumi factory)
C05(E05) – Check TELETEXT Function (Applicable
to the model that has Teletext code set-
up item in Product spec)
