3.4 Function Check

-Check display and sound

■Check Input and Signal items.

1)TV

2)AV (SCART / CVBS)

3)COMPONENT (480i)

4)RGB (PC : 1024 x 768 @ 60hz) (* RGB input : LD21B only support)

5)HDMI

6)PC Audio In (* except LD21A chassis model)

* Display and Sound check is executed by Remote control.

<Caution>

Not to push the INSTOP key after completion if the function inspection.

4. Total Assembly line process

4.1. Adjustment Preparation

▪ W/B Equipment condition CA210

: CCFL/EEFL -> CH9, Test signal: Inner pattern(80IRE) LED -> CH14, Test signal: Inner pattern(80IRE)

▪ If it is executed W/B adjustment in 2~3 minutes H/run, it is adjusted by Target data

Mode	Temp	Coordinate spec	Target
Cool	13,000k	X=0.269 (±0.002)	X=0.271	<Test Signal>
		Y=0.273 (±0.002)	Y=0.276	Inner pattern
		X=0.285 (±0.002)	X=0.287
Medium	9,300k			(204gray,
		Y=0.293 (±0.002)	Y=0.296
				80IRE)
Warm	6,500k	X=0.313 (±0.002)	X=0.315
		Y=0.329 (±0.002)	Y=0.332

*Connecting picture of the measuring instrument (On Automatic control)

Inside PATTERN is used when W/B is controlled. Connect to auto controller or push Adjustment R/C POWER ON → Enter the mode of White-Balance, the pattern will come out.

Full White Pattern CA-210

COLOR

ANALYZER

TYPE : CA-210

RS-232C Communication

*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.
