Main
unit supplied as service unit was adjusted on some item. However, W/B adj is not finished because it
needs to be done by final set condition. So the main unit is in the adjustment
condition when it is supplied and K mark is shown up in display when you use
it. After finishing Factory setting, K -mark disappear so please do it as
following.
ADJUSTMENT PROCEDURE.
The
adjustment values are set to the optimum conditions at the factory before
shipping. If a value should become improper or an adjustment is required due to
part replacement, make an adjustment according to the following procedure.
After replacement of any PWB unit and/or IC for repair, please note the following.
When replacing the following units, make sure to prepare the new units loaded with updated software.
MAIN Unit: DKEYMF216FMG3: LC-60G9T
DKEYMF216FMG4: LC-70G9T
When replacing the LCD control PWB, perform the VCOM adjustment.
Upgrading of each microprocessor software
CAUTION: Never “POWER OFF” the unit when software upgrade is ongoing. Otherwise the system may be damaged beyond recovery.
Software
version upgrade
The model employs the following software.
• Main software LC-60/70G9T (please use a software version after XIAN_G9T_XXX.USB)
• Monitor microprocessor software (please use a software version XIANSUBXXX-SMB)
The main software, monitor microprocessor software can be upgraded by using a general-purpose USB Memory.
The followings are the procedures for upgrading, explained separately for the main software, monitor microprocessor software.

Main
software version upgrade
Get
ready before you start
• USB Memory of 128MB or higher capacity.
• PC running on Windows 98/98SE/ME/2000/XP operating system.
• USB Memory reader/writer or PC with a USB port.
• The file system of a USB memory is FAT. (FAT32 supports)
• Use the USB memory without other functions. (lock and memory reader...etc)

• Use the USB memory without other functions. (lock and memory reader...etc)
Preparations
To upgrade the main software, it is necessary to get ready the USB Memory for version upgrade before you start.
Follow the steps below and create the USB Memory for version upgrade.
1. Copy the file XIAN_G9T-XXX.USB for version upgrade to the root directory (folder) of the USB Memory.
NOTE: In the USB Memory drive, do not store other folders or unrelated files, or more than one file for version upgrade.
Now the USB Memory for version upgrade is ready.
How
to upgrade the software
1. Unplug the AC cord.
2. Insert the USB Memory for version upgrade into USB1.
3. Plug in the AC cord with power button pressed down.
4. After 5 seconds, un-press the power button.
5. After the unit startup, the system upgrade screen as shown below within 20-40 seconds.
1. Unplug the AC cord.
2. Insert the USB Memory for version upgrade into USB1.
3. Plug in the AC cord with power button pressed down.
4. After 5 seconds, un-press the power button.
5. After the unit startup, the system upgrade screen as shown below within 20-40 seconds.
6.
Even a single failure in the process will trigger the upgrade failure screen.
NOTE:
In the event of a failure, repeat the upgrade process. If the process
repeatedly fails, it is likely that the hardware need fixing.
7.
Upon completion of the whole process, the upgrade success screen as shown below
appears. You can check the new software version on this screen. The version
information appears after the upgrade is complete.
8. Unplug the AC cord and remove the USB Memory for version upgrade.
9. Now the software version upgrade is complete.
NOTE: When you are done with the software version upgrade, start the set, go to the top page of the adjustment process screen and check the main software version information.
If you upgrade the software version of 60/70G9T the model name is upgrade screen is displayed as 60/70G9T.
Monitor
microprocessor software version upgrade
Create the USB memory for monitor microprocessor software version upgrade in the same manner as explained in the “Main software version upgrade”.
Copy the file XIAN_G9T_XXX.USB and XIANSUBxxx.SMB. (named temporarily) for monitor microprocessor software version upgrade to the USB memory.
Create the USB memory for monitor microprocessor software version upgrade in the same manner as explained in the “Main software version upgrade”.
Copy the file XIAN_G9T_XXX.USB and XIANSUBxxx.SMB. (named temporarily) for monitor microprocessor software version upgrade to the USB memory.
How to upgrade the software
1. Unplug the AC cord.
2. Insert the USB Memory for version upgrade into USB1.
3. Plug in the AC cord with power button pressed down.
4. After 5 seconds, unpress the power button.
CAUTION: • The moment this operation is done, the upgrading of the monitor microprocessor software starts. While the upgrade is ongoing, never power off the unit. Otherwise the upgrade will fail and the system may be serious damaged beyond recovery (inability to start).
• After the monitor microprocessor software is upgraded, also perform the 'Industry Init'.
5. After the unit startup, the upgrade starts. The power led will blink continuously. Also, an upgrade screen will be shown during a minor upgrade.
6. If the upgrade fails, power led will stop blinking. Also, the upgrade failure screen will be shown if upgrade screen was shown.
NOTE: In the event of a transient failure, upgrade will be automatically retried up to three times. If the process repeatedly fails, hardware may be the cause.
7. The upgrade success screen will be shown if upgrade screen was shown.
8. Unplug the AC cord and remove the USB Memory for version upgrade.
9. Now the software version upgrade is complete.
NOTE: When you are done with the software version upgrade, start the set, go to the top page of the adjustment process screen and check the monitor microprocessor software version information and panel size information.
If you upgrade the software version of 60/70G9T, the model name in upgrade screen is displayed as 60/70G9T.
Entering
and exiting the adjustment process mode [Service Mode]

Next, hold down the “VOL(-)” and “CH(Dn)” keys at a time.
(The “VOL (—)” and “CH (Dn)” keys should be pressed and held until the display appears.)
Multiple lines of blue characters appearing on the display indicate that the unit is now in the adjustment process mode.
When you fail to enter the adjustment process mode (the display is the same as normal startup), retry the procedure.
