ADJUSTMENT INSTRUCTION
1. Application Range
This specification sheet is applied to all of the LCD TV, LP92A
chassis.
2. Specification
(1) Because this is not a hot chassis, it is not necessary to use
an isolation transformer. However, the use of isolation
transformer will help protect test instrument.
(2) Adjustment must be done in the correct order.
(3) The adjustment must be performed in the circumstance of
25 °C ± 5 °C of temperature and 65 % ± 10 % of relative
humidity if there is no specific designation.
(4) The input voltage of the receiver must keep AC 100-220 V~
50 / 60 Hz.
(5) Before adjustment, execute Heat-Run for 5 minutes at RF
no signal.
3. Adjustment items
3.1. PCB assembly adjustment items 
(1) Download the MSTAR main software(IC604, Mstar ISP Utility)
- Using D/L Jig
(2) Input Tool-Option
(3) ADC Calibration - Component
(4) Check SW Version.
3.2. SET assembly adjustment items
(1) Input Area option
(2) Adjustment of White Balance : Auto & Manual
(3) Input Tool-Option/Area option
(4) Preset CH information
(5) Factoring Option Data input
4. PCB assembly adjustment method
4.1. Mstar Main S/W program download
- Using D/L Jig
(1) Preliminary steps
1) Connect the download jig to D-sub(RGB) jack
(2) Download steps
1) Execute ‘ISP Tool’ program, the main window(Mstar ISP
utility Vx.x.x) will be opened
2) Click the “Connect” button and confirm “Dialog Box”
3) Click the “Config” button and Change speed

Filexxx.bin
5) Click “(2)Auto” tab and set as below
6) Click “(3)Run”.
7) After downloading, you can see the “(4)Pass” message.
* If TV is Turn On, Check the updated SW Version and
Tool Option.
4.2. Input tool option.
Adjust tool option refer to the BOM.
- Tool Option Input : PCBA Check Process
- Area Option Input : Set Assembly Process
After Input Tool Option and AC off
Before PCBA check, you have to change the Tool option and
have to AC off/on (Plug out and in)
(If missing this process, set can operate abnormally)
(1) Profile : Must be changed the option value because being
different with some setting value depend on
module maker, inch and market 
(2) Equipment : adjustment remote control.
(3) Adjustment method
- The input methods are same as other chassis.(Use IN-
START Key on the Adjust Remote control.)
(If not changed the option, the input menu can differ the
model spec.)
Refer to Job Expression of each main chassis ass’y
(EBTxxxxxxxx) for Option value  
[Caution]
- Don’t Press “IN-STOP” key after completing the function
inspection.
- Don’t connect HDMI cable when downloading the EDID.
If the cables are connected, Downloading of EDID could
be failed.
4.3. EDID Data
* 32LD310 <HDMI : 256 Byte>
(1) EDID D/L method
1) Press the In-start key
2) Move to the System Control2 and Press the OK(   )
3) Move to the EDID D/L and press the right direction
key(
G
)
4) After about a few seconds, appear “OK’, then complete.
5) Press the OK key(   ).
6) Press the EXIT key.
4.4. ADC Calibration-Component
- Using External pattern
(1) Required Equipments
- Remote control for adjustment
- MSPG-925F/MSPG-1025/MSPG-3233 Pattern Generator
(2) Process
1) Change the Input to Component mode.
2) Input the Component 720P@60 Hz 100 % Color Bar
YPbPr signal into Component
(MSPG-925F Model: 217 / Pattern: 65)
3) Press ADJ key on R/C for adjustment.
4) Enter Password number. Password is “0 0 0 0”.
5) Select “Auto-RGB” and press OK(   ) key.
6) ADC adjustment is executed automatically .
7) When ADC adjustment is finished, this OSD appear
“COMPONENT-OK”
(3) Confirmation
1) Adjust by commanding AUTO_COLOR_ADJUST (0xF1)
0x00 0x02 instruction.
2) We confirm whether “0xF3 (offset), 0xF4 (gain)” address
of EEPROM “0xBC” is “0xAA” or not.
3) If “0xF3”, “0xF4” address of EEPROM “0xBC” isn’t
“0xAA”, we adjust once more.
4) We can confirm the ADC values from “0x06~0x0B”
addresses in a page “0xBC”.
