* Target value

(6) When adjustment is completed, Exit adjustment mode
using EXIT key on R/C.

Step 1) Press the EYE Key on the Adjustment remote

controller.

Step 2) Screen the Eye Q sensor in front of the TV by hands,

and keep up about 6 seconds.

Step 3) Checking “Raw Data(R:  G:  B:  )” value are changed

less than “10”, or not. If the values are not changed,
exchange the sensor unit by soldering.

Step 4) Pull out the hands, keep up about 6 seconds.
Step 5) Checking “B.Light(XXX)” value increase from “0”, or

not. If the values are not changed, exchange the
sensor unit by soldering.

(1) GND & Auto Inspection for against surge voltage

-Confirm that the power cord is inserted TV SET perfectly.

(2) Operation the GND & Auto Inspection for against surge

voltage

1) The TV set is entered auto inspection Line. Undoubtedly

the TV set is confirmed that Power cord, Tuner cable,
A/V cables are inserted perfectly.

2) Connect the D-terminal AV JACK tester.
3) Turn on the Auto controller (GWS103-4)
4) Operate the GND test
5) If case of NG, the BUZZER will be alarmed.
6) Case of OK, the process will be changed Inspection for

against surge voltage automatically.

(Disconnect the cord, A/V from AV JACK box)

7) Start the Inspection for against surge voltage TEST
8) If case of NG, the BUZZER will be alarmed.
9) Case of OK, GOOD LAMP will be turned on and the TV
moved next process.

(3) Caring Items

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 fl‡ SIGNAL

CABLE METAL GND 

- Inspection for against surge voltage test = Power cord

GND fl‡ live & neutral

4) Leakage Current : Setting less than 0.5mArms

(1) The method of Cable connecting from jig to TV.

1) Power Cable is connected to jig for supplying voltage.

(as below picture point2)

2) Phone jack is Connected for IR out test from TV

REMOTE CONTROL OUT(JK900) to jig. (as below
picture point1)

3) In the right side of check jig, 11pin SPI/MPI signal cable

is connected to MPI dummy board. (as below picture
point3)

(2) Test sequence

1) Press EYE using adjust remote-control.
2) Then, tuning the channel 96- 1.(Lodgenet digital1.)

automatically.

3) Check it whether the video is clear and 1~5 factor “OK”

like below picture.

(IR IN / IR OUT / SPI TEST / MPI TEST / 12V IN)
If you find any problem, press <Eye> button and retest.

(1) adjust remote-control
(2) commercial check jig & adapter
(3) 11 pin cable
(4) Phone jack Cable

After D-box on, AC power Off and On.
When available AV signal comes to side AV jack, input mode
changing to AV2 automatically.
