Preparations
To upgrade the main software, it is necessary
to get ready the SD card for version upgrade before you start.
Follow the steps below and create the SD card for version upgrade.
1. Insert the SD card into the SD card reader/writer. Start the SD card formatting software. Click [Format].
(When you have the drive options, select the drive where the SD card is inserted before you proceed.)
Follow the steps below and create the SD card for version upgrade.
1. Insert the SD card into the SD card reader/writer. Start the SD card formatting software. Click [Format].
(When you have the drive options, select the drive where the SD card is inserted before you proceed.)
2. When the formatting is over, Click [OK].

How to upgrade the software
5. Shut off the AC power (i.e. unplug the AC
cord).
6. Insert the SD card for version upgrade (prepared as above) into the service socket located lower side from center at terminals, under DIGITAL
AUDIO OUTPUT terminal in the rear of the unit, in a way that the cut corner of the SD card comes at the upper side.
NOTE: If the SD card is inserted in a wrong way, the card will go deep inside the unit beyond retrieval. Take due care to insert the SD card correctly.
7. Turn on the AC power (i.e. plug in the AC cord).
8. After the unit startup, the system upgrade screen will appears within 15~30 seconds.

8. After the unit startup, the system upgrade screen will appears within 15~30 seconds.
9. Even a single failure in the process will
trigger the upgrade failure screen as shown below. The word “NG” changes to red
for the item failed.
NOTE: In the event of a failure, repeat the upgrading process. If the process repeatedly fails, it is likely that the hardware is troubled.

10.Upon completion of the whole process, the
upgrade success screen appears. You can check the new software version on this
screen. The version information appears after the upgrade is complete.
11.Shut off the AC power to the unit (unplug the AC cord), and remove the SD card for version upgrade.
12.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
screen. The version information appears after the upgrade is complete.

software version information
Monitor microprocessor software
version upgrade
NOTE: If “Monitor version” in the process menu is “2.00M”, the monitor microprocessor software can not be rewritten (because IC2002 has been
replaced with the mask type).
NOTE: If “Monitor version” in the process menu is “2.00M”, the monitor microprocessor software can not be rewritten (because IC2002 has been
replaced with the mask type).
Get ready before you begin
Get ready the same items as listed in the
“Main software version upgrade”.
Preparation
Create the SD card for monitor microprocessor
software version upgrade in the same manner as explained in the “Main software
version upgrade”. Copy the binary image files D42UMxxx.SDC and D42UMxxx.BIN
(named temporarily) for monitor microprocessor software version upgrade to the
SD card drive.
How to upgrade the software
1. Shut off the AC power to the unit (i.e.
unplug the AC cord).
2. Insert the SD card for version upgrade (prepared as above) into the service socket located lower side from center at terminals, above S-VIDEO terminal in the rear of the unit, in a way that the cut corner of the SD card comes at the upper side.
NOTE: If the SD card is inserted in a wrong way, the card will go deep inside the unit beyond retrieval. Take due care to insert the SD card correctly.
3. Turn on the AC power (i.e. plug in the AC cord).
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 have a serious damage beyond recovery (inability to start).
4. After the unit startup, the system upgrade screen appears within 15~30 seconds.

White balance adjustment
[Adjustment procedure]
1) Using the remote controller, transmit the “monitor adjustment process” code.
2) Set the 6th point to the specified gradation level. With the strongest color being fixed, turn down the R, G and B settings to their reference levels.
3) Set the 5th point to the specified gradation level. Correct the G setting (800 x 6thpoint G setting / 928) (rounded off), and make the R and B settings to their reference levels.
4) Set the 4th point to the specified gradation level. Correct the G setting (680 x 6thpoint G setting / 928) (rounded off), and make the R and B settings to their reference levels.
5) Set the 3rd point to the specified gradation level. Correct the G setting (480 x 6thpoint G setting / 928) (rounded off), and make the R and B settings to their reference levels.
6) Set the 2nd point to the specified gradation level. Correct the G setting (232 x 6thpoint G setting / 928) (rounded off), and make the R and B settings to their reference levels.
7) Set the 1st point to the specified gradation level. Correct the G setting (184 x 6thpoint G setting / 928) (rounded off), and make the R and B settings to their reference levels.
8) With the MSET0003 command, write the adjustment values and turn off the AC power.
# Initial R, G and B settings at point 6: Gradation level set at 928
# Initial R, G and B settings at points 1 thru 5: Corrected G setting at each point (This is because the adjustment is made to achieve the same remainder of RGB setting /
4 at each point.)
