5.7. EYE-Q Green Function Inspection
Step 1) Turn on the TV..
Step 2) Press 'EYE button' on the adjustment remote-
controller.
Step 3) Cover 'Eye Q sensor' on the front of set with your
hands, hold it for 6 seconds.
Step 4) Check "the Sensor Data" on the screen, make certain
that Data is below 10. If Data isn’t below 10 in 6
seconds, Eye Q sensor would be bad. You should
change Eye Q sensor.
Step 5) Uncover your hands from Eye Q sensor, hold it for 6
seconds.
Step 6) Check "Back Light(xxx)" on the screen, check data
increase . You should change Eye Q sensor.
5.8. Ship-out mode check (In-stop)
▪ After final inspection, press In-Stop key of the Adj. R/C and
check that the unit goes to Stand-by mode.

7. GND and HI-POT Test
7.1. GND & HI-POT auto-check preparation
(1) Check the POWER CABLE and SIGNAL CABE insertion
condition
7.2. GND & HI-POT auto-check
(1) Pallet moves in the station. (POWER CORD / AV CORD is
tightly inserted)
(2) Connect the AV JACK Tester.
(3) Controller (GWS103-4) on.
(4) GND Test (Auto)
- If Test is failed, Buzzer operates.
- If Test is passed, execute next process (Hi-pot test).
(Remove A/V CORD from A/V JACK BOX)
(5) HI-POT test (Auto)
- If Test is failed, Buzzer operates.
- If Test is passed, GOOD Lamp on and move to next process
automatically.
