062-393 CCD PWB Sync Signal Fail RAP
BSD-ON:
BSD 6.6 - Image Input
•
Write failure to the Shading Memory has occurred.
•
Averaging processing error has occurred in the ASIC.
NOTE: When turning the power OFF, turn OFF the power switch first and then the main power
switch.
Procedure
1.
Turn the power ON and enter the Diag mode. Change the value for NVM location [715-
030] to "1" and then execute "NVM Write".
2.
A 3 or 4-digit number is displayed in the current value column.
3.
Check the upper 1 or 2 digits, or the lower 2 digits using the following table and replace
the appropriate parts.
Sample Display
•
110 (3-digit display):
LED Lamp PWB failure and LED Lamp Flexible Flat Cable is damaged or has poor
contact.
(The first digit "1" in "110" is the upper digit, which indicates the LED Lamp PWB ("0"
in "01" is not displayed). The lower 2 digits "10" indicates the LED Lamp Flexible Flat
Cable.)
•
1000 (4-digit display):
The LED Lamp Flexible Flat Cable is damaged or has poor contact.
(The first 2 digits "10" in "1000" are the upper digits, which indicates the LED Lamp
Flexible Flat Cable. The lower 2 digits "00" indicates that nothing is applicable (no
failures).)
NOTE: Execute the IIT diagnosis and then call NVM location[715-030] again (press the
Change Settings button) to check the value (diagnosis result).
4.
After replacing the appropriate parts, again change the value for NVM location [715-030]
to "1" and then execute "NVM Write".
5.
Check that the current value column becomes "000".
6.
If the problem persists after performing the above procedure, check the following:
•
Check the Flat Cable between the CCD Lens Assembly
P/J700
and the IIT PWB
P/
J710
for open circuits, short circuits, and poor contacts (especially, check whether
the Flat Cable was inserted in a skewed manner).
•
The coaxial cable between the IIT PWB
P/J7191
and the ESS PWB
P/J336
for
open circuit, short circuit, and poor contact
If no problems are found, replace the following parts in sequence:
•
If the problem persists, reload the machine software (
GP 16
).
•
ESS PWB (
PL 35.2
)
•
IIT PWB (Switch the EEPROM) (
PL 1.6
)
