2). Monitor microprocessor software version upgrade
 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 file for monitor microprocessor software version
upgrade to the SD card drive.
 How to upgrade the software
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.
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.
  Note:  If the SD card isn't inserted properly, the card will go deep inside the unit beyond retrieval.  Take due care
to insert the SD card correctly.
  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 While depressing the SYSTEM RESET button, turn on the AC power (i.e. plug in the AC cord).(The power
supply by the side of a monitor is ON state.)
 ~ After startup of the unit, 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).
4 After startup of the unit, the power LED starts flashing within 10 or so seconds.
5 Wait until the power LED stops flashing, the unit restarts automatically and then the normal startup screen
appears (it will take 2-3 minutes).
6 Shut off the AC power to the unit (unplug the AC cord), and remove the SD card for version upgrade.
7 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.
3). Card microprocessor software version upgrade
 Get ready before you start
  * CF (Compact Flash) of 32MB or higher capacity
  * PCMCIA adapter for CF
  * PC with PCMCIA slot running on Windows 98/98SE/ME/2000/XP operating system
 Creating the PC card for version upgrade
Formatting the PC card
1  Insert the PC card into the PC card slot.
2 Open [My Computer] window, choose the relevant drive (e.g. H drive) and right-click it.
3 Select [Format] in the menu.
4 Under the file system, there are [FAT32] and [FAT] options.  Select [FAT], and click [Start].
5 A dialog box requesting your confirmation appears.  Click [OK].

TU-65GD1E
LC-65GD1E
6 Wait until the formatting is over.  Then click [OK].
After this, click [Close].
Creating a new "boot" folder directly under the card root directory
1 Create H:¥boot if the card is in H:¥drive.
2 Click [File], point to [New Creation], and click [Folder].
3 Rename the folder as [boot].
Copying the version upgrade file to the PC card
Using a drag-and-drop action, copy the "aqb5cu.img" (temporarily named) file for version upgrade to the "boot"
folder.
 Removing the PC card
1 Click [Safely removing hardware] in the task bar, select [PCMCIA IDE/ATAPI Controller], and click [Stop].
2 Select PC card in [Stop hardware device], and click [OK].
3 After confirming that you can safely remove the hardware, remove the PC card.
Now the PC card for version upgrade is ready.
How to rewrite the software
After rewriting the software, check the version No. in the process mode.
1 With the set still powered on, pull the AC power plug out of the wall outlet to turn it off forcedly.
2  Insert into the set the PC card created in "Creating the PC card for version upgrade" described above.
3 Insert the AC power plug back into the wall outlet.
4 Select the card mode by pressing the menu button.
5 The card microcomputer programs are read from the PC card automatically.
Wait for about 2 minutes until the reading is completed.
"NOW BLOCK NUMBER ERASING" appears on the OSD.
"NOW FLASH WRITING NUMBER" appears.
"VERIFYING" appears.
"UPDATE SUCCEEDED" appears.
If "Card error…" appears, wait a while. To check the process, press the menu button.
Step 2:
After "Card is being read" appears, the PC card thumbnail screen returns.
* If the reading ends in failure, perform the above steps 1 to 5 again after power-off.
6 Disconnect the AC power plug from the wall outlet to turn off the set forcedly.
