4. Total Assembly line process
*Connection
4.1. Tool option & ADC Check
1) Press "Power on" key of service remote control.
2) Connect audio signal cable to phone jack for RS232.
3) Check the 'Tool Option' (Refer to the BOM Comments or
Adjustment spec)
4) Check the ‘ADC’ is ok.
4.2. Model name & Serial number Down-
load
4.2.1. Model name & Serial number D/L
1) Press "Power on" key of service remote control.
2) Connect RS232 Signal Cable to RS-232 Jack.
3) Write Serial number by use RS-232.
4) Must check the serial number at the Diagnostics of SET UP
menu. (Refer to below).
4.2.2. Method & notice
1) Model Name & Serial Number D/L is using of scan equip-
ment.
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
4) Check the model name Instart menu → Factory name
displayed (ex 24LN4500)
5) Check the Diagnostics (DTV country only) → Buyer model
displayed (ex 24LN4500)
4.3. Function Check
4.3.1. Check display and sound
*Check Input and Signal items. (cf. work instructions)
1) TV
2) AV (CVBS)
3) COMPONENT (480i)
4) HDMI
* Display and Sound check is executed by Remote controller.
→ Caution : Not to push the INSTOP KEY after completion if
the function inspection.
4.4. White balance adjustment
-Equipment
1) Color Analyzer: CA-210 (LED Module : CH 14)
2) Adj. Computer(During auto adj., RS-232C protocol is
needed)
3) Adjust Remocon
RGB_Gains are fixed data for each model.
Insert RS-232C Jack which is connected with PC for White
Balance or equivalent device.
* Total Assembly line should be check whether the color
coordinate(x,y) data refer to below table were meet or not.
Color coordinate is differ from panel’s characteristics of color
temperature. Please check panel characteristics about color
temperature.
-Warm Panel(22LB4510)
-Cool Panel (24LB4510)
*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.
