REPLACING THE CCD IMAGE SENSOR
1.3.1 Removing the CCD image sensor
(1) As a consequence of 1.2, disassemble the boards as shown
in fig. 1-2-4.
(2) Remove the two screws

and remove the CCD board.
(3) Remove the CCD image sensor which soldering on the CCD
board.

Note:
• The image sensor is interchangeable only with a speci-
fied image sensor.
• New image sensors and crystal filters should be han-
dled so as not to leave fingerprints or grease on their
glass surfaces.
To remove attached dirt or grease blow on the glass
surface until it becomes misted then wipe it gently
with a cotton swab. (Do not use alcohol or other simi-
lar substances.)
• After replacement, all of the adjustments should be
performed from the beginning.
• Note that the image sensor is susceptible to static
damage. Be sure to take anti-static measures before
replacing it.
• After an image sensor has been removed, an electri-
cal charge may remain on the terminals of the cam-
era circuit for a certain period of time.
If a new image sensor is inserted into the socket in
this condition, the image sensor may b instantly dam-
aged by the remaining electric charge. To prevent this
happening, wait a while (2 to 3 minutes) after remov-
ing an image sensor until inserting another one in
the socket.
• After the CCD board has been removed from the SEN-
SOR BASE, the back-focus adjustment should be per-
formed again.
