SERVICING NOTES
NOTE THE EACH BOARDS REPAIRING
The mount parts on each boards installed in this set cannot ex-
change with single. When the each board are damaged, exchange
the entire mounted board.
REWRITING THE LUT
The LUT is exclusive for each lot number of the ELEMENT INK
INDICATOR 5 INCH(L). Therefore, when replacing the complete
MAIN board or LGD PANEL ASSY, you need to rewrite the LUT.
However, rewriting is not required if the lot number is the same.
Location where the LUT is stored:
• IC1203
How to check the version of the stored LUT:
• Enters the test mode referring to “HOW TO ENTER THE
TEST MODE” (page 8) in TEST MODE. Check the current
LUT version displayed at the right side of “Update Waveform”
as in the screen below. The LUT version is “0400040113” in
this example.
(Screen display)
How to check the lot number of the ink (indication)
ELEMENT ASSY:
• The lot number is written on the label on the flexible card wire.
The lot number is “B19” in the picture below.
How to change the LUT:
1. Connect this set with PC by the USB cable.
2. Unzip the application for the test mode, and the “Sony Reader”
folder is made.
Note: Confirm the method of obtaining the application for the test mode
to each service headquarters.
3. Execute the copy of the “Sony Reader” folder made in step 2
to the Reader’s drive on the My Computer.
4. Copy the LUT file you want to update to the folder under “/
Sony Reader/software” in the Reader’s drive, and then change
the name to “lut.bin”.
5. Release the connection of this set and PC and it enters the test
mode.
6. The current LUT version displayed at the right side of Update
Waveform on TEST MODE MENU.
7. In the state that a Update Waveform tab is selected if it is press
the [3] button, next press the [ENTER] button, it starts rewrit-
ing LUT version.
Note: It is necessary to match the LUT version to the version in elation
to the lot number of the ELEMENT INK INDICATOR 5INCH
(L). Refer to Technical News about details.
8. After a few minutes (about 10 seconds), the screen display is
refreshed, a LUT version display of the right side of Update
Waveform on TEST MODE MENU is refreshed.
Note: For the VCOM adjustment value of RV1801 for each lot, refer to

ELECTRICAL ADJUSTMENT
VCOM VOLTAGE ADJUSTMENT
Vcom voltage for the display panel varies for each panel. VCOM
adjustment is required when replacing a board or panel.
Preparation:
Voltage is generated only when the screen is changed, so the
adjustment needs to be performed while changing the screen. Use
the slideshow function to change the screen sequentially.
1. With the “Settings” tab in the menu selected, press the
[ENTER] button or the [0] button.

[ENTER] button or the [9] button.
2. Specify a desired screen, and press the [ENTER] button to
check that the slideshow starts.
3. Observe the TP354 on an oscilloscope (refer to Fig.2), and use
RV1801 to adjust the voltage that is generated when the screen
is changed so that it satisfies the standard.
Standard: Written on the flexible card wire of the display panel with
a marker. (–1 V to –2.5 V) (Refer to following Fig.1)
(In case of Fig.1: The value of VCOM is –1.75 V.)
