1.6 DISASSEMBLY OF 7 OP BLOCK ASSEMBLY/CCD
BOARD ASSEMBLY
1.6.1 Precautions
1. Carefully handle the CCD image sensor, optical LPF, lens,
etc. during the disassembly work. Pay the most careful
attention to the surface of those parts not to get it soiled,
scratched or dusty. If some of those surfaces gets soiled
with fingerprints, etc., wipe it out with silicone paper, clean
chamois, cleaning cloth or the like.
2. The new CCD image sensor is occasionally shipped from
the factory as a protection seal is applied onto its
transparent glass. If so, leave the protection seal as it is
and remove it just before installing the CCD image sensor
in the OP block assembly.
1.6.2 How to remove OP block assembly and CCD board
assembly
1. Unsolder at the two points (SD1) and remove the shield
case.
2. Unsolder at the sixteen points (SD2) and remove the CCD
board assembly.
3. Remove the two screws (1, 2) and then remove the CCD
base assembly.
Note 6 a: Carefully remove the CCD base assembly, because
the space rubber and optical LPF may be removed
together with the CCD image sensor.
Note 6 b: When replacing the CCD image sensor, don’t
replace it individually but replace the CCD base
assembly in whole with a new one.

1.6.3 How to install OP block assembly and CCD board
assembly
1. Install the optical LPF with the space rubber fitted to its
CCD side in the OP block assembly.
2. Paying heed to the space rubber not to get it to come off
the setting position, install the CCD base assembly in
place and fasten it together with the space rubber with the
two screws (1, 2).
3. Set the CCD board assembly in the CCD base assembly,
and fasten it by soldering at the fourteen points (SD2).
4. Install the shield case and fasten it by soldering at the two
points (SD1).
1.6.4 Replacement of service parts
Service parts to be supplied for the OP block assembly are as
follows.
When replacing a part, be very careful not to get the FPC wire
broken or damaged by soldering (overheating).
1. Focus motor
2. Zoom motor
3. Iris motor unit
Note 6 c: When soldering the FPC wire of the focus motor or
zoom motor during the replacement work, be sure
to keep the tip of a soldering iron approximately 1
mm above the terminal.
Note 6 d: The iris motor unit includes one FPC assembly and
two sensors.
