*. Adj. condition and cautionary items
1) Lighting condition in surrounding area Surrounding lighting
should be lower 10 lux. Try to isolate adj. area into dark
surrounding.
2) Probe location
- LCD: Color Analyzer (CA-210) probe should be within 10cm
and perpendicular of the module surface (80°~ 100°)
3) Aging time
- After Aging Start, Keep the Power ON status during 5
Minutes.
- In case of LCD, Back-light on should be checked us-
ing no signal or Full-white pattern.
5.3.6. Reference (White balance Adj. coordinate and
color temperature)
▪ Luminance: 255 Gray
▪ Standard color coordinate and temperature using CS-1000 (over
26 inch) [applied only LGD Module]
▪ Standard color coordinate and temperature using CA-210(CH 14)
[applied only LGD Module]
5.3.7. Color coordination according to aging time
▪ Luminance: 255 Gray, 100IRE
▪ Standard color coordinate and temperature using CA-
210(CH-14) – by aging time

5.4. Ship-out mode check (In-stop)
▪ After nal inspection, press In-Stop key of the Adj. R/C and
check that the unit goes to Stand-by mode
6. GND and HI-POT Test
6.1 Method
1) GND & HI-POT auto-check preparation
- Check the Power Cable and Signal Cable insertion condi-
tion.
2) GND & HI-POT auto-check
a. Pallet moves in the station. (POWER CORD / AV CORD is
tightly inserted)
b. Connect the AV JACK Tester.
c. Controller (GWS103-4) on.
d. GND Test (Auto)
- If Test is failed, Buzzer operates.
- If Test is passed, execute next process (Hi-pot test). (Re-
move A/V CORD from A/V JACK BOX)
e. HI-POT test (Auto)
- If Test is failed, Buzzer operates.
- If Test is passed, GOOD Lamp on and move to next
process automatically
6.2 Check Point
1) Test voltage
- GND: 1.5KV/min at 100mA
- SIGNAL: 3KV/min at 100mA
2) TEST time: 1 second
3) TEST POINT
- GND Test = POWER CORD GND and SIGNAL CABLE
GND.
- Hi-pot Test = POWER CORD GND and LIVE & NEUTRAL.
4) LEAKAGE CURRENT: At 0.5mArms
