3.2.5 DISASSEMBLY OF [15] OP BLOCK ASSY/CCD BOARD ASSY
Precautions
(1) Be careful in handling the CCD IMAGE SENSOR, OPTICAL
LPF and the LENS components.
Pay special attention to the surfaces to protect them from
stains, dust, or scratches.
If the surfaces are soiled with finger prints or other stains,
wipe them off with silicon paper,
(2) The CCD IMAGE SENSOR may have been shipped with
a protective sheet attached to the transmitting glass.
When replacing the CCD IMAGE SENSOR, do not peel
off this sheet from the new part until immediately before
it is mounted in the OP BLOCK ASSY.
Disassembly of OP BLOCK ASSY / CCD BOARD ASSY
(1) Remove the two screws (1,2), and then remove the
SHIELD(CCD-2M)1 ASSY.
(2) Remove the two screws (3,4), and then remove the CCD
BOARD ASSY and the CCD BASE ASSY.
NOTE15a:
When removing the CCD BASE ASSY, be careful in
handling as the CCD IMAGE SENSOR may be removed
together with the SHEET and the OP LPF attached.
NOTE15b:
Be careful in handling the CCD BASE ASSY as this
CCD BASE ASSY is surface mounted unlike previous
models.
When handling the CCD BOARD ASSY or removing
the FPC with the CCD BASE ASSY mounted, always

NOTE15c:
Replace the CCD IMAGE SENSOR as a CCD BASE
ASSY, not as a single part replacement.
(3) Remove the SHEET and the OP LPF.
(4) Remove the SHIELD from the SHIELD (CCD) 1 ASSY,
unsolder the 24 soldered points (SD15a) on the CCD
BOARD ASSY, and then remove the CCD BASE ASSY
and the SHIELD (CCD) 1 ASSY.
(5) Remove the two screws (5,6), and then remove the CCD
BASE ASSY.
Replacement of service repair parts
The service repair parts for the OP BLOCK ASSY are as listed below.
When replacing parts, be careful not to cut the FPCs or dam-
age any parts by soldering (excessive heat).
(1) FOCUS MOTOR UNIT
(2) ZOOM MOTOR UNIT
(3) IRIS MOTOR UNIT
NOTE 15d:
When replacing the FOCUS MOTOR UNIT or the ZOOM
MOTOR UNIT, solder the FPC at a space of about 0.5 mm
above the terminal pin.
NOTE 15e:
The IRIS MOTOR UNIT includes the FPC ASSY and two sensors.
