mality occurs to be NG once, the NG state is
kept until the main power is turned OFF.
• Measurement value: The measurement value at the time when
HARDWARE CHECK menu is displayed is
displayed. 
The measurement value at the time when an
abnormality occurred is saved in the log data.
*The measurement value of the internal voltage displayed is the A/D
conversion value. The normal range is as shown below.
4) For the countermeasures against NG positions, refer to “7. Hard-
ware check NG” in “CHAPTER 5. TROUBLESHOOTING.”
5) Press MENU button to return to the previous screen, and terminate
the operation.

The white balance setting is used to correct shade variations in each
panel. When the panel is not changed, take over the panel setting to
suppress variations. When the panel is changed, perform resetting to
set the standard state. 
(2) When replacing the PWB (when the panel is not 
changed)
(2)-1. White Balance setting information read
The White Balance setting information of the information display before
replacement is read. There are two methods to read the White Balance
setting information as follows. 
•  Method 1: The setting information is read from the SERVICE MENU. 
•  Method 2: Use the White Balance setting read tool. 
Use either way to read the White Balance setting information. 
Since the white balance is set in the PC system input mode, read the
setting information in the PC system input mode. 
[Method 1]
The setting information is read from the SERVICE MENU. 
[Operating procedures]
1)  Select the PC system input mode with [INPUT] button. 
• Select one of PC1 DIGITAL, PC2 ANALOG, and PC3 ANALOG
modes.
2)  Any image is displayed on the screen.
3)  SERVICE MENU2 is displayed. 
4)  Select “WHITE BALANCE SETTING” with [
2 ] [ 4 ] buttons, and
press [
3] button. 
The WHITE BALANCE SETTING menu is displayed. 
“(PC)” is displayed on the title column. 
5)  Check to confirm that the PATTERN item is “9000K”.
If it is “6500K”, use [
2 ] [ 4 ] buttons to select “PATTERN” and use
[
3]  button to select “9000K.”
6) Use 
[
2 ] [ 4 ] buttons to select “LEVEL” and press [3] button. The
LEVEL menu is displayed. 
7)  Check to confirm that the setting information is same as the above
display.
If the setting information differs from the above display, the setting
information cannot be taken over. Refer to “(3) When replacing the
panel or when the old PWB does not operate” to reset the setting
information to the default values. (Unless a change is made individ-
ually, these procedures are not required in normal cases.)
8)  Select “CANCEL” with [
2 ] [ 4 ] [1] [3] buttons and press [MENU]
button. 
The display returns to the WHITE BALANCE SETTING menu.
9) Write down all the displayed set values of R, G, and B in L1 - L6. 
10) Select “CANCEL” with [
2 ] [ 4 ] [1] [3] buttons and press [MENU]
button.
The WHITE BALANCE SETTING menu is terminated. 
[Method 2]
Use the White Balance setting read tool. 
For detailed operation procedures of the tool, refer to the separate
sheet (3-6. WHITEBALANCE SETTING READ TOOL OPERATING
PROCEDURE).
[Operating procedures]
1) Connect the information display and the PC with the RS-232C
straight cable. 
2) Boot the tool, “InfoDispWhiteBalance.exe”.
3) Turn ON the power of the information display. 
4) Press [READ] button of the tool.
5)  After normal completion of reading data, check to confirm that the
setting information of L1 - L6 on the PC side is as shown in the fig-
ure below. 
If the setting information differs, the setting information cannot be
taken over. Refer to “(3) When replacing the panel or when the old
PWB does not operate” to reset the setting information to the
default values. (Unless a change is made individually, these proce-
dures are not required in normal cases.)
6)  Write down the setting values of 1 - 6 of R/G/B on the PC side.
(Refer to the figure below.)
* Though the setting values of the AV input system are read too,
since only the setting values of the PC system input are used,
write down only the setting values of the PC system input.
