							1-38 (No.YF100) 3.2.5 DISASSEMBLY of [11] OP BLOCK ASSY/CCD BOARD ASSY
zCAUTIONS
(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.
zDisassembly procedure of OP BLOCK ASSEMBLY/CCD
BOARD ASSEMBLY
(1) Remove the HOOD and the OP FRAME ASSEMBLY
first, before disassembling the OP BLOCK ASSEMBLY.
(2) Remove the two screws (1,2) and connector (CN11a),
then remove the CDS BOARD ASSEMBLY.
NOTE11a:
When removing, take out the WIRES prior to other
procedure.
NOTE11b:
When attaching, be careful with the wiring.
(3) Remove the screw (3), and then remove the JOINT PLATE
(4) Remove the two screws (4,5), and then remove the FO-
CUS RING ASSEMBLY.
(5) Remove the two screws (6-8), and then remove the OP
FRAME ASSEMBLY.
NOTE11c:
When attaching, be careful with the GASCKET.
(6) Remove the two screws (9, 10), then remove the CCD
BOARD ASSEMBLY and the HEAT SINK (CCD) at the
same time.
NOTE11d:
When replacing the CCD IMAGE SENSOR, unsolder
the fourty two soldered parts (SD11a), 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.
NOTE11e:
When attaching, firmly attach the HEAT SINK to the
HEAT SHEET with screws.
(7) Remove the three screws (11-13), and then remove the
PRISM ASSY.
zReplacing 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 UNIT
(2) ZOOM MOTOR UNIT
(3) AUTO IRIS UNIT
NOTE11f:
When replacing the FOCUS MOTOR or the ZOOM
MOTOR, space the FPC approximately 1 mm above
from the jack and then solder it (SD11b).
NOTE11g:
When assembling, make sure to interlock the slide
part of the OP BLOCK properly to the axis of the
ZOOM MOTOR.
NOTE11h:
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.
NOTE11j:
IRIS MOTOR UNIT includes the FPC ASSEMBLY and
the SENSOR x 2. Fig.OP1

SECTION 4
ADJUSTMENT
4.1 PREPARATION
4.1.1 Precaution
Camera system and deck system of this model are specially
adjusted by using PC. 
However, if parts such as the following are replaced, an
adjustment is required. The adjustment must be performed in a
Service Center equipped with the concerned facilities.
• OP BLOCK ASSEMBLY
• MONITOR ASSEMBLY
• EEP ROM (IC4504 of  DIGITAL board)
In the event of malfunction with electrical circuits, first find a
defective portion with the aid of proper test instruments as shown
in the following electrical adjustment procedure, and then
commence necessary repair/ replacement/adjustment.
• In observing chip TP, use IC clips, etc. to avoid any stress.
Prior to replacement of chip parts (especially IC), remove the
solder completely to prevent peeling of the pattern.
• Use a patch cord if necessary. As for a patch cord, see the
BOARD INTERCONNECTIONS.
• Since connectors are fragile, carefully handle them in
disconnecting and connecting the FPC. 
4.1.2 REQUIRED TEST EQUIPMENT
• Personal computer (for Windows)
• Color TV monitor
• Oscilloscope (dual-trace type, observable 100MHz or higher
frequency). The one observable 300 MHz or higher frequency
is recommended.
• Digital voltmeter
• DC power supply or AC adapter
• Frequency counter (with threshold level adjuster)4.1.3 TOOLS REQUIRED FOR ADJUSTMENT 
•  Torque driver
Be sure to use to fastening the mechanism and exterior parts
because those parts must strictly be controlled for tightening
torque.
•  Bit
This bit is slightly longer than those set in conventional torque
drivers.
•  Tweezers
To be used for removing and installing parts and wires.
•  Chip IC replacement jig
To be used for adjustment of the camera system.
•  Cleaning cloth
Recommended the Cleaning cloth to wipe down the video
heads, mechanism (tape transport system), optical lens sur-
face.
