GND and HI-POT Test, Checkpoint | LG Electronics 42CS669C-ZD

4.2. EYE-Q function check

Step 1) Turn on the TV set.

Step 2) Press “EYE” key on Adjustment remote control.

Step 3) Cover the Eye Q sensor at the front of set for 6 seconds. Step 4) Check the value of Sensor Data. It must be below 10.

If not so, the Eye Q sensor may have some defect. Change the Eye Q sensor.

Step 5) Wait for 6 seconds after withdrawing form the Eye Q sensor.

Step 6) Check the value of Backlight. It must rise.

If not so, the Eye Q sensor may have some defect. Change the Eye Q sensor.

<Step 2>	<Step 3>	<Step 4>

* EYE-Q Test is except for LV23xx/LK33x/LK43x series.

4.3. Outgoing condition Configuration

-When pressing IN-STOP key by Service remote control, Red LED are blinked alternatively. And then automatically turn off. (Must not AC power OFF during blinking)

5.GND and HI-POT Test

5.1. GND & HI-POT auto-check preparation

Check the Power cable and Signal cable insertion condition

5.2.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.

5.3.Checkpoint

(1)Test voltage

-GND: 1.5 KV / min at 100 mA

-SIGNAL: 3 KV / min at 100 mA

(2)TEST time: 1 second

(3)TEST POINT

-GND Test = Power cord GND and Signal cord GND.

-Hi-pot Test = Power cord GND and LIVE & NEUTRAL.

(4)LEAKAGE CURRENT: At 0.5 mArms

6.Model name & Serial number D/L

•Press “Power on” key of service remote control. (Baud rate : 115200 bps)

•Connect RS232 Signal Cable to RS-232 Jack.

•Write Serial number by use RS-232.

•Must check the serial number at the Diagnostics of SET UP menu(Refer to below.)

6.3. Method & notice

A. Serial number D/L is using of scan equipment.

B. Setting of scan equipment operated by Manufacturing Technology Group.

C. Serial number D/L must be conformed when it is produced in production line, because serial number D/L is mandatory by D-book 4.0.
