PURPOSE
- The Vcom (Common Voltage) is a Reference Voltage of Liquid Crystal Driving. > Liquid Crystal need for Polarity Change with every frame.
- Press the PIP key of th ADJ remote control.(This PIP key is hot key to enter the VCOM adjuting mode). (Or After enter Service Mode by pushing “ADJ” key, then Enter V-Com Adjust mode by pushing “G” key at “10. VCom”)
- As pushing the right or the left key on the remote control, and find the V-COM value which is no or minimized the Flicker. (If there is no flicker at default value, Press the exit key and finish the VCOM adjustment.)
- Push the “OK” key to store value. Then the message “Saing OK” is pop.
- Press the exit key to finish VCOM adjustment.
(Visual Adjust and control the Voltage level)
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)
INTERNAL PRESSURE
- Confirm whether is normal or not when between power board’s ac block and GND is impacted on 1.5 kV(dc) or 2.2 kV(dc) for one second.
MODEL NAME AND SERIAL NUMBER [D/L]
- 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).

METHOD AND NOTICE
- Serial number D/L is using of scan equipment.
- Setting of scan equipment operated by Manufacturing Technology Group.
- 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.
