							(No.YF200)1-15 3.2.3 DISASSEMBLY OF [14] VF ASSY
zBefore disassembly
As the VF ASSEMBLY has complicated structure, do not dis-
assemble if not needed. 
When assembling, be careful to prevent dust or any foreign
materials entering inside, and avoid soils on both the LENS
and the SHEET.
zDisassembly procedure
(1) Remove the 3 screws (1-3), and then remove the
BKT(VF).
(2) Remove the screw (4), and remove the VF SHOE
PLATE.
NOTE14a:
When removing the VF SHOE PLATE, be careful in
handling as the SLIDE STOPPER 1 and 2 come off.
(3) Peel off the FPC from the OUT CASE (VF), and then
carefully remove the SLIDE CASE (VF) ASSY by sliding
it out.
NOTE14b:
During the procedure, be careful in handling the FPC.
NOTE14c:
When attaching, put the CLICK PLATE inside the OUT
CASE (VF).
(4) Remove the 2 screws (5,6), and then remove the TOP
COVER(VF).
NOTE14d:
When removing the TOP COVER, be careful as the
SHEET (PROTECT) comes off.
(5) Remove the SHEET(PROTECT).
(6) Set the LEVER(VF) to the MARK(z)of the S.CASE(VF)
ASSY, and then remove the LENS1 and 2 ASSYS.
NOTE14e:
When attaching the LENS1 and 2 ASSYS, set the
LENS2 ASSY into the LENS1 ASSY first. Adjust the
positioning mark of the LEVER (VF) to the MARK(z)of
the SLIDE CASE (VF) ASSY before attaching.
NOTE14f:
When removing the LEVER (VF), turn the LEVER (VF)
further clockwise and set the pointed positioning mark
to the top.
(7) Press hooks (L14a,b) on both sides of the HOLD-
ER(LCD) to remove the LCD SA from the CASE(VF).      
NOTE14g:
During the procedure, be careful in handling the
switches (VF OPEN/VF SUB OPEN) on both sides.
When attaching, pay special attention not to damage
the parts. 
(8) Pull out the FPC from the connector (CN14), and then re-
move the VF BL BOARD ASSY from the CASE (BL).
NOTE14h:
Do not disassemble the LCD SA unless it is required
for LCD module replacement. During the procedure,
be careful to prevent dust or any foreign materials from
entering inside.
NOTE14j:
During the procedure, be careful not to damage the
parts.

							(No.YF200)1-17 3.2.4 DISASSEMBLY OF [21] OP BLOCK ASSY/CCD BOARD ASSY
zPrecautions
(1) The OP BLOCK ASSY in this model has more complicated
structure than conventional OP BLOCK ASSY.
he relevant parts for CCD BASE ASSY and the OP LPF,
that used to be disassembled, are in one unit structure
as PRISM ASSY.
During the procedure, disassemble the OP BLOCK
ASSY only when needed, and be careful not to give any
external shock or vibration.
(2) During the procedure, be careful in handling the FPC
and 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, clean chamois leather,
or recommended cleaning cloth.
zDisassembly procedure
(1) Unsolder the total of 42 soldered points (SD21a) from
the 3 CCDS, 14 soldered points from each CCD, and
then remove the CCD BOARD ASSY from the PRISM
ASSY. 
(2) Remove the screw (1), and then remove the HEAT SINK
(CCD) ASSY.
NOTE21a:
During the procedure, be careful in handling the HEAT
SHEET(CCD).
(3) Remove the 3 screws (2-4), and then remove the PRISM
ASSY.zReplacing service repair parts
The service repair parts for the OP BLOCK ASSEMBLY are as listed
below.
Take special care not to disconnect any of the FPC wires or
cause any damage due to soldering (excessive heating).
• FOCUS MOTOR UNIT
• ZOOM MOTOR UNIT
• IRIS MOTOR UNIT
• SENSOR
• SCREW (for MOTOR)
• SCREW (for SENSOR)
• SPRING
• SPACERS (A), (B)
NOTE21b:
When removing the FOCUS MOTOR UNIT and ZOOM MO-
TOR UNIT, be sure to peel off the SHEET and remove the
SPRING before removing the screws.
During the procedure, be careful in handling the parts. Avoid
reusing the peeled SHEET, and be sure to replace it with a
new SHEET.
NOTE21c:
When attaching the SPRING, be careful not to break or lose
the parts and be sure to hook both sides to the HOOKS.
NOTE21e:
When soldering the FPC of the FOCUS MOTOR UNIT or the
ZOOM MOTOT UNIT, lift the FPC a little from the terminal
and leave the clearance between them.
NOTE21f:
Although the IRIS MOTOR UNIT includes the FPC ASSY, it
does not include the 2 sensors.
When replacing the IRIS MOTOR UNIT, it is necessary to
reattach the sensors.
NOTE21g:
 When attaching the IRIS MOTOR UNIT, be careful in han-
dling and wiring the FPC.

tached to the BOARD sticks out toward the LCD
screen.
(9) Remove the SPACER(PET). 
(10) Remove the BACK LIGHT,LCD MODULE,SPAC-
ER(LCD) and the BKT(LCD).
NOTE30c:
During the procedure disassemble the four parts (BACK
LIGHT, LCD, SPACER (LCD), and BLACKET (LCD)) if
necessary as they can be removed from the MONITOR
CASE ASSY as a whole.
zRemoving HINGE UNIT ASSY
(1) Remove the screw (9), and Remove the HINGE COV-
ER(U).
NOTE30d:
