ADJUSTMENT INSTRUCTION
1. Application Range
This specification sheet is applied to all of the LCD TV with
LC03M chassis.
2. Designation
(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 ºC ± 5 ºC of temperature and 65 % ± 10 % of relative
humidity if there is no specific designation.
(4) The input voltage of the receiver must keep AC 100-240
V~ 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. Automatic Adjustment
3.1. ADC Adjustment
(1) Overview
ADC adjustment is needed to find the optimum black level
and gain in Analog-to-Digital device and to compensate
RGB deviation.
(2) Equipment & Condition

2) MSPG-925 Series Pattern Generator(MSPG-925FA,
pattern - 65)
- Resolution : 480i Comp1
1080P Comp1
1920*1080 RGB
- Pattern : Horizontal 100% Color Bar Pattern
- Pattern level : 0.7±0.1 Vp-p
- Image
(3) Adjustment
1) Adjustment method
