(1)Adjust in the place where the influx of light like floodlight around is blocked. (illumination is less than 10 lux).

(2)Adhere closely the Color analyzer(CA210) to the module less than 10 cm distance, keep it with the surface of the Module and Color analyzer's prove vertically.(80° ~ 100°).

(3)Aging time

-After aging start, keep the power on (no suspension of power supply) and heat-run over 5 minutes.

-Using 'no signal' or 'POWER ONLY' or the others, check the back light on.

<Caution>

Color Temperature : COOL, Medium, Warm.

One of R Gain/G Gain/ B Gain should be kept on 0xC0, and adjust other two lower than C0.(When R/G/B Gain are all C0, it is the FULL Dynamic Range of Module)

* Manual W/B process using adjust Remote control.

5. GND and HI-POT Test

5.1. HI-POT auto-check preparation

- Check the POWER cable and SIGNAL cable insertion condition

5.2.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)HI-POT test (Auto)

-If Test is failed, Buzzer operates.

-If Test is passed, GOOD Lamp on and move to next proc- ess automatically.

5.3.Checkpoint

(1)Test voltage

-Touchable Metal : 3 KV / min at 100 mA

-SIGNAL : 3KV / min at 100 mA

(2)TEST time: 1 second. (case : mass production )

(3)TEST POINT

-Touchable Metal => LIVE & NEUTRAL : Touchable Metal.

-SIGNAL => LIVE & NEUTRAL : SIGNAL.

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

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

After enter Service Mode by pushing "ADJ" key,

Enter White Balance by pushing "►" key at

*After you finished all adjustments, Press "In-start" key and compare Tool option and Area option value with its BOM, if it is correctly same then unplug the AC cable. If it is not same, then correct it same with BOM and unplug AC cable. For correct it to the model's module from factory Jig model.

*Push the "IN STOP" key after completing the function inspection. And Mechanical Power Switch must be set “ON”.

4.5.Outgoing condition Configuration

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