4.2 Function Check
4.2.1 Check display and sound
■ Check Input and Signal items. (cf. work instructions)
1. TV
2. AV
3. COMPONENT (480i)
4. HDMI
* Display and Sound check is executed by Remote controller.
☞
Caution : Not to push the INSTOP KEY after completion if the function inspection.
5. Total Assembly line process
5.1 Adjustment Preparation
■ W/B Equipment condition
CA210 : CCFL/EEFL

■ Above 5 minutes H/run in the inner pattern. (“power on” key of adjust remote control)
5.1.1 W/B adj. Objective & How-it-works
(1) Objective: To reduce each Panel
’s W/B deviation
(2) 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.
(3) Adj. condition: normal temperature
- Surrounding Temperature: 25±5
℃
- Warm-up time: About 5 Min
- Surrounding Humidity: 20% ~ 80%
-
Before White balance adjustment, Keep power on status, don
’t power off
※
If Model is POLA model ( LS3150/3450 )
Case : Cool Mode
l
Purpose : Adjust the color temperature to reduce the deviation of the module color temperature.
l
Principle : To adjust the white balance without the saturation,
Fix the G gain to 172 (default data) and
change the others ( R/B Gain )
.
l
Adjustment mode : mode – Cool
Case : Medium / Warm Mode
l
Purpose : Adjust the color temperature to reduce the deviation of the module color temperature.
l
Principle : To adjust the white balance without the saturation,
Fix the one of R/G/B gain to 192 (default data) and
decrease the others
.
