LG Electronics 32CS560-ZD Flat Panel Television User Manual


 
4.2. EYE-Q function check
Step 1) Turn on the TV set.
Step 2) Press “EYE” key on Adjustment remote control.
Step 3) Cover the Eye Q sensor at the front of set for 6 seconds.
Step 4) Check the value of Sensor Data. It must be below 10.
If not so, the Eye Q sensor may have some defect.
Change the Eye Q sensor.
Step 5) Wait for 6 seconds after withdrawing form the Eye Q
sensor.
Step 6) Check the value of Backlight. It must rise.
If not so, the Eye Q sensor may have some defect.
Change the Eye Q sensor.
* EYE-Q Test is except for LV23xx/LK33x/LK43x series.
4.3. Outgoing condition Configuration
- When pressing IN-STOP key by Service remote control, 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. GND & HI-POT auto-check preparation
Check the Power cable and Signal cable insertion condition
5.2. 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.
5.3. 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 cord GND.
- Hi-pot Test = Power cord GND and LIVE & NEUTRAL.
(4) LEAKAGE CURRENT: At 0.5 mArms
6. Model name & Serial number D/L
• Press “Power on” key of service remote control.
(Baud rate : 115200 bps)
• Connect RS232 Signal Cable to RS-232 Jack.
• Write Serial number by use RS-232.
• Must check the serial number at the Diagnostics of SET UP
menu(Refer to below.)
6.1. Signal TABLE

6.2. Command Set
* Description
FOS Default write : <7mode data> write
Vtotal, V_Frequency, Sync_Polarity, Htotal, Hstart, Vstart, 0,
Phase
Data write: Model name and Serial number write in EEPROM,.
6.3. Method & notice
A. Serial number D/L is using of scan equipment.
B. Setting of scan equipment operated by Manufacturing
Technology Group.
C. 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.
