(2) Medium / Warm Mode
1) Purpose : Adjust the color temperature to reduce the
deviation of the module color temperature.
2) Principle: To adjust the white balance without the saturation,
- In Medium mode, Fix to G gain to 192 and change the
others(R/B Gain)(20LB45X model)
- Fix the one of R/G/B gain to 192(default data) and
decrease the others.
3) Adjustment mode : Two modes - Medium / Warm
5.6. Reference(White Balance Adjustment
coordinate and color temperature)
(1) Luminance: 204 Gray, 80IRE
(2) Standard color coordinate and temperature using CS-1000
(over 26 inch)
■ The spec of color temperatre and coordinate for Auto W/B.
* Note : x,y coordinates are drifted about 0.007 after 30 mins
heat-run. So checking color coordinate within 5-min at
total assembly line, consider x,y coordinates might be
up to 0.007 than x,y target of each color temperature.

6. Tool Option setting & Inspection per
countries
(1) Press 'IN START' key at Factory Service remote control.
(2) Select 'Tool Option 1'.
(3) Punch in the number and press 'OK'. (Each of models has
their number)
(4) Correct 'Tool Option2' ~ 'Tool Option5'.
(5) Completed adjusting Tool option.
7. Ship-out mode check (In-stop)
▪ After final inspection, press In-Stop key of the Adjustemnt
Remote Control and check that the unit goes to Stand-by mode.
8. AUDIO output check
8.1. Audio input condition
(1) RF input: Mono, 1 KHz sine wave signal, 100% Modulation
(2) CVBS, Component: 1 KHz sine wave signal (0.4 Vrms)
8.2. Specification
9. GND and HI-POT Test
9.1. GND & HI-POT auto-check preparation
(1) Check the POWER CABLE and SIGNAL CABE insertion
condition
9.2. 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.
9.3. 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 CABLE
GND.
- Hi-pot Test = POWER CORD GND and LIVE &
NEUTRAL.
(4) LEAKAGE CURRENT: At 0.5 mArms
