4.2. EYE-Q function check
(1) Turn on TV.
(2) Press “EYE” key on Adjustment remote control.
(3) Cover the Eye Q sensor at the front of set for 6 seconds.
(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.
(5) Wait for 6 seconds after withdrawing form the Eye Q
sensor.
(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.
4.3. Outgoing condition Configuration
■ When pressing IN-STOP key by SVC remocon, 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). (Re-
move 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 proc-
ess 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 CABLE 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
CMD : A0h
LENGTH : 85~94h (1~16 bytes)
ADH : EEPROM Sub Address high (00~1F)
ADL : EEPROM Sub Address low (00~FF)
Data : Write data
CS : CMD + LENGTH + ADH + ADL + Data_1 +...+ Data_n
Delay : 20ms
6.2. Comand 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
(1) Serial number D/L is using of scan equipment.
(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.
