1.1 REPLACING THE FUSE
(1) Set the power switch to OFF.
(2) Remove the POW board. (See section 1.6.3)
(3) Fuse F1 is located on the POW board.
(For the part No. of fuse, see Symbol No. 29 on page 4-2.)
CAUTION
Before replacing a fuse and in order to prevent a recur-
rence of the same trouble, investigate what caused the
fuse to blow, repair it and confirm normal operation. To
protect the equipment and provide safety, be sure to
replace with a fuse having the specified part number.

1.5 REPLACING THE CCD IMAGE SENSOR
䡵The image sensor is interchangeable only with a specified
image sensor.
䡵New image sensors and crystal filters should be handled so
as not to leave fingerprints or grease on their glass surfaces.
To remove attached dirt or grease, blow on the glass surface
until it becomes misted then wipe it gently with a cotton
swab. (Do not use alcohol or other similar substances.)
䡵After replacement, all of the adjustments should be performed
from the beginning.
䡵Note that the image sensor is susceptible to static damage.
Be sure to take anti-static measures before replacing it.
䡵After an image sensor has been removed, an electrical charge
may remain on the terminals of the camera circuit for a cer-
tain period of time.
If a new image sensor is inserted into the socket in this con-
dition, the image sensor may be instantly damaged by the
remaining electric charge. To prevent this happening, wait a
while (2 to 3 minutes) after removing an image sensor until
inserting another one in the socket.
䡵After the CCD board has been removed from the lens as-
sembly, the back-focus adjustment should be performed
again.

1.7 REPLACEMENT OF IC223 ON THE SW-CPU BOARD
(1) A special tool is available for use in removing IC223 (please
purchase SUN HAYATO Model GY-X8 or similar tool
separetely). Two small screwdrivers can also be used in place
of the special tool.
(3) When inserting the IC, align the IC orientation and fit it into
position with a finger, taking care that the attached IC is not
tilted.
(2) When using the special tool, fit sections A of the tool into
grooves B on the opposite corners of the IC socket and re-
move the IC as if pinching it up.
When using small screwdrivers, fit their tips into the grooves
ay the opposite corners of the IC socket and remove the IC
as if pulling it up.

2.6 ADJUSTMENT OF THE WIDE-ANGLE LIMIT POSITION
• This is to adjust the wide-angle limit position for the zoom ring. This instrument is delivered after the camera has been adjusted.
Thus, there are no adjustment needs except for the replacement of the lens assemblies.
• This unit uses a variable-focal lens, if the wide-angle limit position is not in the right position, the correct focus may not be
obtained depending on the zoom position. Thus, the following adjustment must be performed when replacing the lens assem-
bly.
(1) Loosen the wide-angle limit setting screw Å
of the lens.

(2) Turn the focus ring of the lens to the ıposi-
tion as shown in the left diagram.
(3) Bring a subject at a distance of 3 meters into

 SCHEMATIC DIAGRAM NOTES
• Schematic safety precaution
!Parts are safety related parts.
When replacing them, be sure to use the specified parts.
• Voltage and waveform measurements
Voltage: Measured with digital voltmeter in DC range;
lens closed.
Waveform: Gray scale illuminated at more than 4000 lux at
3200K lighting.
• Unit of value
Unless otherwise specified
1) Resistance is in Ω(1/6 W)
2) Capacitance is in µF
3) Inductance is in µH
 REPLACING SURFACE MOUNT “CHIP” COMPONENTS
• Some resistors, shorting jumpers (0 Ωresistance), ceramic
capacitors, transistors, and diodes are chip parts. These chip
parts cannot be reused after they are once removed.
• Chip resistors used in some circuits are of high precision
type having little error in resistance.
To demonstrate the full capacity of this set, place an order
for proper parts referring to the diagrams and parts lists in
the section 5.
• Soldering cautions:
1) Do not apply heat for more than 3 seconds.
2) Avoid using a rubbing stroke when soldering.
3) Discard removed chips; do not reuse them.
4) Supplementary cementing is not required.
5) Use care not to scratch or otherwise damage the chips.
