3.2.4 DISASSEMBLY of [12] OP BLOCK ASSY/CCD BOARD ASSY
CAUTIONS
(1) Since the OP BLOCK on this model is more complicated
in structure than previous OP BLOCKS, pay extra
attention to external shocks and vibrations.
(2) During the procedure, be careful in handling the CCD
IMAGE SENSOR, OP LPF and the LENS etc. Pay extra
attention to the soil, dust and scratch on the surface.
If fingerprints are left on the screen, wipe them with clean
chamois leather or a cleaning cloth.
(3) CCD IMAGE SENSORS may sometimes be shipped
from the factory with the protection seal applied on the
transparent glass. After the replacement, do not remove
the protection seal until right before assembling the CCD
IMAGE SENSOR to the OP BLOCK ASSEMBLY.
Disassembly procedure of OP BLOCK ASSEMBLY/CCD
BOARD ASSEMBLY
(1) Remove the SPACER RUBBER.
(2) Take out the OP LPF.
NOTE12a:
When replacing the CCD IMAGE SENSOR, unsolder
the sixteen soldered parts (SD12a), and remove the
CCD BASE ASSEMBLY from the CCD BOARD
ASSEMBLY.
Replace the CCD IMAGE SENSOR as a CCD BASE
ASSEMBLY, not as a single part replacement.
NOTE12b:
When attaching the OP LOPF, be careful to attach in
the correct direction.

Replacing service repair parts
The service repair parts of the OP BLOCK ASSEMBLY are as
follows.
When replacing the parts, pay special attention not to break
the FPC, or not to damage the parts by soldering (overheat).
(1) FOCUS MOTOR
(2) ZOOM MOTOR
(3) IRIS MOTOR UNIT
NOTE12c:
When replacing the FOCUS MOTOR or the ZOOM
MOTOR, space the FPC approximately 1 mm above
from the jack and then solder it (SD12b).
NOTE12d:
When assembling, make sure to interlock the slide
part of the OP BLOCK properly to the axis of the
ZOOM MOTOR.
NOTE12e:
When removing the IRIS MOTOR UNIT, fully pull the
slide part which is interlocked to the axis of the
FOCUS MOTOR to the CCD side.
NOTE12f:
IRIS MOTOR UNIT includes the FPC ASSEMBLY and
the SENSOR x 2.
