* Auto-control interface and directions
(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.

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.
▪ After enter Service Mode by pushing "ADJ" key,
▪ Enter White Balance by pushing "►" key at "8. White
Balance".
* 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)
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.

6.3. Method & notice
(1) Serial number D/L is using of scan equipment.
(2) Setting of scan equipment operated by Manufacturing
Technology Group.
(3) 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.
* Manual Download(Model Name and Serial Number)
If the TV set is downloaded by OTA or Service man, sometimes
model name or serial number is initialized.(Not always)
There is impossible to download by bar code scan, so It need
Manual download.
