ADJUSTMENT INSTRUCTION
1. Application Range
This specification sheet is applied to all of the LCD TV with
LA92G 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 ±5ºC of temperature and 65±10% of relative humidity if
there is no specific designation.
4) The input voltage of the receiver must keep 100~240V,
50/60Hz.
5) The receiver must be operated for about 5 minutes prior to
the adjustment when module is in the circumstance of over
15.
* In case of keeping module is in the circumstance of 0°C, it
should be placed in the circumstance of above 15°C for 2
hours.
In case of keeping module is in the circumstance of below -
20°C, it should be placed in the circumstance of above
15°C for 3 hours,.
*Caution
When still image is displayed for a period of 20 minutes or
longer (especially where W/B scale is strong. Digital pattern
13ch and/or Cross hatch pattern 09ch), there can some
afterimage in the black level area.

3) Use the certificated cable. 
5.1.3 Method
5.1.3.1 ADC 480i Comp1
Set Component 480i mode and 100% Horizontal Color Bar
Pattern(HozTV31Bar), then set TV set to Component1 mode
and its screen to “NORMAL”
After get the signal, wait more a second and enter the “In
START” with press In-Start key of Service remocon. After then
select  “6. External ADC-> Comp 480i” with navigator button
and press “Enter”. It is automatically adjustment
You can see “ADC Component Success” message after
Adjustment success Error Messages: When its adjustment is
not correct, “ADC Component Fail”message displayed.
If its signal don’t out, then “Check Signal Status” message
displayed. These messages will be displayed just a second.

5.2 White Balance adjustment
5.2.1 Overview
• W/B adjustment : Objective & How-it-works
- Objective: to reduce each Panel’s W/B deviation
- How-it-works: when R/G/B gain in the OSD is at 192, it
means the panel is at its Full Dynamic Range. In order to
prevent saturation of Full Dynamic range and data, one of
R/G/B is fixed at 192, and the other two is lowered to find
the desired value.
5.2.2 Equipment
1) Color Analyzer : CA-210 (NCG: CH 9 / WCG: CH12
/LED Module:CH14)
2) Adjustment Computer (During auto adj., RS-232C
protocol is needed)
3) Adjustment R/C
4)Video Signal Generator MSPG-925F 720p/216Gray
(Model:217, Pattern:78)
-> Only when internal pattern is not available
•Color Analyzer Matrix should be calibrated using CS-1000
