This unit has main and monitor
microcomputer softwares.
These can be rewritten via a
general-purpose SD memory card.
The
procedures to rewrite the main and monitor microcomputer softwares are
described below.
MAIN SOFTWARE VERSION UPGRADE.
- SD memory card of 16MB or higher capacity
- PC running on Windows 98/98SE/ME/2000/XP operating system
- SD memory card reader/writer with USB connectivity and PC card adapter
- SD memory card formatting software [Download it by this link]
PREPERATIONS
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.
- 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.)
- When the formatting is over, Click [OK].
- Click [End] to finish the formatting.
- When you are done, take out the SD card once to make sure it is finished, and then insert it again.
- Copy the binary image file KA1UAxxx.SDC (named temporarily) for version upgrade to the root directory (folder) of the SD card drive.
Note: In the SD card drive, do not
store other folders or unrelated files, or more than one binary image files for
version upgrade.
- Now the SD card for version upgrade is ready.
TO UPGRADE SOFTWARE
- Pull out the AC cord to turn off the TV.
- Insert the SD card for version upgrade (prepared as above) into the service socket located below left of the right side cooling fan in the rear of the unit, in a way that the cut corner of the SD card comes at the righthand 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.
- Hold down the "SYSTEM RESET" button at the lower left of the rear of the unit, and plug in the AC cord to turn on the TV.
- Note: The "SYSTEM RESET" button can be released after the TV turns on.
- Several to ten-odd seconds after the unit starts, the following version upgrade screen appears.
- 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.
- 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.
- Put off the AC power to the unit (unplug the AC cord), and remove the SD card for version upgrade.
- 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.
MONITOR MICROPROCESSOR SOFTWARE VERSION UPGRADE
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 file for
monitor microprocessor software version upgrade to the SD card drive.
During the monitor microprocessor
software version upgrade, the progress of upgrading is not shown on the display
screen. The upgrading process is seen in the blinking of the power LED.
- Shut off the AC power to the unit (i.e. unplug the AC cord).
- Insert the SD card for version upgrade (prepared as above) into the service socket located below left of the right side cooling fan in the rear of the unit, in a way that the cut corner of the SD card comes at the righthand 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.
- While depressing the SYSTEM RESET button located below the RS-232C connector in the rear left side of the unit, turn on the AC power (i.e. plug in the AC cord).
Note: After the unit is started, you
may release the SYSTEM RESET 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 have a serious
damage beyond recovery (inability to start).
- After the unit startup, the power LED starts blinking in green within 10-20 seconds.
- Wait until the power LED stops blinking, the unit restarts automatically, and the normal startup screen appears (it will take 2-3 minutes).
- Shut off the AC power to the unit (unplug the AC cord), and remove the SD card for version upgrade.
- 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.
