3.2.5 DISASSEMBLY of [13] OP BLOCK ASSEMBLY/CCD BOARD ASSEMBLY
z
CAUTIONS
(1) Be careful in handling the CCD image sensor, OP LPF,
and lens etc., especially not to damage or soil their sur-
face.
If it is soiled with fingerprints, etc., gently clean it with
chamois or the cleaning cloth.
(2) When the CCD image sensor is shipped from the factory,
there are protection seals applied onto the transparent
glass. Leave the protector as it is, and take it off just be-
fore assembling the CCD image sensor to the OP block.
z
Disassembly
(1) Remove the two screws (1 and 2), and remove the CCD
BOARD ASSEMBLY together with CCD BASE ASSEM-
BLY.
(2) Remove the LOW PASS FILTER HOLDER from the
CCD BASE ASSEMBLY, and remove the MASK.
NOTE 13a:
Since the MASK is between the LOW PASS FILTER
HOLDER and CCD IMAGE SENSOR, be careful in
handling the MASK.
NOTE13b:
In removing the CCD IMAGE SENSOR, unsolder the
fourteen soldered parts (SD13a), and remove the
CCD BASE ASSEMBLY from the CCD BOARD AS-
SEMBLY.
In replacing the CCD IMAGE SENSOR, don't remove
the CCD IMAGE SENSOR from the CCD BASE AS-
SEMBLY. Instead, replace the whole CCD BASE AS-
SEMBLY.
NOTE13c:
Since the OP LPF is inside the LOW PASS FILTER
HOLDER and the OP LPF is attached to the LOW
PASS FILTER HOLDER by using the SHEET, remove
the OP LPF from the LOW PASS FILTER HOLDER if
necessary.
In removing the OP LPF from the LOW PASS FILTER
HOLDER, be careful not to damage the LOW PASS
FILTER HOLDER, and remove the SHEET carefully if
you want to use the same SHEET in attachment pro-
cedure.
NOTE13d:
In removing the OP LPF, be careful of the direction of
its attachment. Since one side of the OP LPF is coated
for the purpose of protection, attach the OP LPF so
that the coated side faces the OP lens (a subject of
photograph).
z
Replacement of service repair parts
Service repair parts of the OP BLOCK ASSEMBLY are as fol-
lows.
When replacing the parts, be careful not to cut or damage the
FPC, and not to damage the parts due to soldering (overheat).
(1) FOCUS MOTOR
(2) ZOOM MOTOR
(3) IRIS MOTOR
NOTE 13e:
When replacing the FOCUS MOTOR or the ZOOM
MOTOR, lift the FPC approx.1mm away from the jack
in soldering the FPC (SD13b).
NOTE13f:
IRIS MOTOR contains the FPC ASSEMBLY and the
SENSOR
