● When Color temperature (White balance) Adjustment
(Automatically)
- Press “Power only key” of service remocon and operate
automatically adjustment.
- Set BaudRate to 115200.
● You must start “wb 00 00” and finish it “wb 00 ff”.
● If it needs, then adjustment “Offset”.
■ White Balance Adjustment (Manual adjustment)
● Test Equipment: CA-210
- Using PDP color temperature, Color Analyzer (CA-210)
must use CH 10, which Matrix compensated (White, Red,
Green, Blue compensation) with CS-2100. See the
Coordination bellowed one.
● Manual adjustment sequence is like bellowed one.
- Turn to “Ez-Adjust” mode with press ADJ button of service
remocon.
- Select “10.Test Pattern” with CH+/- button and press
enter. Then set will go on Heat-run mode. Over 30
minutes set let on Heat-run mode.
- Let CA-210 to zero calibration and must has gap more
10cm from center of PDP module when adjustment.
- Press “ADJ” button of service remocon and select
“7.White-Balance” in “Ez-Adjust” then press “►” button of
navigation key. (When press “►” button then set will go to
full white mode)
- Adjust at three mode (Cool, Medium, Warm)
- If “cool” mode
Let B-Gain to 192 and R, G, B-Cut to 64 and then control
R, G gain adjustment High Light adjustment.
- If “Medium” and “Warm” mode Let R-Gain to 192 and R,
G, B-Cut to 64 and then control G, B gain adjustment
High Light adjustment.
- All of the three mode
Let R-Gain to 192 and R, G, B-Cut to 64 and then control
G, B gain adjustment High Light adjustment.
- With volume button (+/-) you can adjust.
- After all adjustment finished, with Enter (■ key) turn to
Ez-Adjust mode. Then with ADJ button, exit from
adjustment mode
* Attachment: White Balance adjustment coordination and
color temperature.
● Using CS-1000 Equipment.
- COOL : T=11000K, ∆uv=0.000, x=0.276 y=0.283
- MEDIUM : T=9300K, ∆uv=0.000, x=0.285 y=0.293
- WARM : T=6500K, ∆uv=0.000, x=0.313 y=0.329
● When tester will measure on Cool condition, adjust W30 on
TV display menu.
● When tester will measure on medium condition, adjust 0 on
TV display menu.
● When tester will measure on warm condition, adjust W30 on
TV display menu.

6. GND and ESD Testing
6.1. Prepare GND and ESD Testing.
■ Check the connection between set and power cord
6.2. Operate GND and ESD auto-test.
■ Fully connected (Between set and power cord) set enter the
Auto-test sequence.
■ Connect D-Jack AV jack test equipment.
■ Turn on Auto-controller(GWS103-4)
■ Start Auto GND test.
■ If its result is NG, then notice with buzzer.
■ If its result is OK, then automatically it turns to ESD Test.
■ Operate ESD test
■ If its result is NG, then notice with buzzer.
■ If its result is OK, then process next steps. Notice it with
Good lamp and STOPER Down.
6.3. Check Items.
■ Test Voltage
● GND: 1.5KV/min at 100mA
● Signal: 3KV/min at 100mA
■ Test time: just 1 second.
■ Test point
● GND test: Test between Power cord GND and Signal
cable metal GND.
● ESD test: Test between Power cord GND and Live and
neutral.
■ Leakage current: Set to 0.5mA(rms)
