4. Total Assembly line process
4.1. Adjustment Preparation
(1) W/B Equipment condition
CA210: CH 9, Test signal: Inner pattern (85IRE)
(2) Above 5 minutes H/run in the inner pattern. (“power on”
key of adjust remote control)
(3) 15 Pin D-Sub Jack is connected to the AUTO W/B
EQUIPMENT.
(4) Adjust Process will start by execute I2C Command (Inner
pattern (0xF3, 0xFF).
(5) Adjust Process will finish by execute I2C Command (Inner
pattern (Inner pattern (0xF3,0x00)).
** Caution **
Color Temperature: COOL, Medium, Warm
One of R Gain/G Gain/ B Gain should be kept on 0xC0, and
adjust other two lower than C0.
(when R/G/B Gain are all C0, it is the FULL Dynamic Range
of Module)
* Manual W/B process using adjusts Remote control.
After enter Service Mode by pushing “ADJ” key,
Enter White Pattern off of service mode, and change off -> on.
Enter “W/B ADJUST” by pushing “
G
” key at “3.W/B ADJUST”.
* After done all adjustments, Press “In-start” button and
compare Tool option and Area option value with its BOM, if it
is correctly same then unplug the AC cable.
If it is not same, then correct it same with BOM and unplug
AC cable.
For correct it to the model’s module from factory JIG model.
* Don’t push The “IN STOP KEY” after completing the function
inspection.
4.2. DPM operation confirmation
(Only Apply for MNT Model)
Check if Power LED Color and Power Consumption operate
as standard.
- Set Input to RGB and connect D-sub cable to set
- Measurement Condition: (100~240V@ 50/60Hz)
- Confirm DPM operation at the state of screen without Signal
4.3 DDC EDID Write (RGB 128Byte )
- Connect D-sub Signal Cable to D-Sub Jack.
- Write EDID DATA to EEPROM (24C02) by using DDC2B
protocol.
- Check whether written EDID data is correct or not.
4.4. DDC EDID Write (HDMI 256Byte)
- Connect HDMI Signal Cable to HDMI Jack.
- Write EDID DATA to EEPROM(24C02) by using DDC2B
protocol.
- Check whether written EDID data is correct or not.
4.5 Serial number (RS-232C)
- Press “Power on” key of service remocon. (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).
