5.1.1.1. 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.

6. GND and Hi-pot Test
6.1. Method
6.1.1. GND & HI-POT auto-check preparation
(1) Check the POWER CABLE and SIGNAL CABE
insertion condition
6.1.2. 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)
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).
- 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
- If Test is passed, GOOD Lamp on and move to next
process automatically.
6.2. Checkpoint
• TEST voltage
- GND: 1.5KV/min at 100mA
- SIGNAL: 3KV/min at 100mA
- SIGNAL: 3KV/min at 100mA
• TEST time: 1 second
• TEST POINT
• TEST POINT
- GND TEST = POWER CORD GND & SIGNAL CABLE
METAL GND
NEUTRAL
• LEAKAGE CURRENT: At 0.5mArms
7. EYE-Q Check
Step 1) Turn on the TV.
Step 2) Press EYE button in adjust remote control.
Step 3) Stay 6 seconds with Eye Q sensor hidden located on
Step 2) Press EYE button in adjust remote control.
Step 3) Stay 6 seconds with Eye Q sensor hidden located on
the front of the set.
Step 4) Check the “Sensor Data” on the screen and check
whether the value is lower thanafter 6 seconds, the
value does not go below 10, Eye Q sensor is not
working properly. Then, change the sensor.
value does not go below 10, Eye Q sensor is not
working properly. Then, change the sensor.
Step 5) Remove hand from the Eye Q II sensor and stay for 6
seconds.
Step 6) Check whether the “Back Light (xxx)” value has risen
on the screen. If after 6 seconds and the value still
does not go high, the eye Q II sensor is not working
properly. Replace the sensor.
