3.2.3 ASSEMBLY/DISASSEMBLY OF [11] OP BLOCK ASSY
Precautions
(1) Be careful in handling the CCD IMAGE SENSOR, OP
LPF and the LENS components. Pay special attention
not to soil or damage the surfaces., especially with re-
gard to surface contamination, attached dust or scratch-
ing. If fingerprints are present on the surface they should
be wiped away using either a silicon paper, clean cham-
ois or the cleaning cloth.
(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 ASSEMBLY / CCD BOARD AS-
SEMBLY
(1) Unsolder the 14soldered points (SD11a) of the CCD
BOARD ASSY.
(2) Remove the two screws (1,2), and then remove the CCD
BOARD ASSY and the CCD BASE ASSY.
NOTE11a:
When removing the CCD BASE ASSY, be careful in
handling as the CCD IMAGE SENSOR may be re-
moved together with the SHEET and the OP LPF at-
tached.
NOTE11b:
Replace the CCD IMAGE SENSOR as a CCD BASE
ASSY, not as a single part replacement.

Assembly of OP BLOCK ASSEMBLY / CCD BOARD AS-
SEMBLY
(1) Set the OP LPF first, and then the SHEET to the OP
BLOCK ASSY.
NOTE11c:
Be careful with the attachment direction of the OP
LPF.
(2) Attach the CCD BASE ASSY first, then the CCD BASE
ASSY so that the SHEET stays in place, and then tighten
with the two screws(1,2).
(3) Solder the 14 points (SD11a) on the CCD BOARD AS-
SY.
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 11d:
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 11e:
The IRIS MOTOR UNIT includes the FPC ASSY and two
sensors.
