1. SERVICE NOTE

1-1. CHEMICALS

Some chemicals used for servicing are highly volatile.
Their evaporation caused by improper management affects your health and environment, and wastes resources.
Manage the chemicals carefully as follows.

• Store chemicals sealed in a specific place to prevent from exposure to high temperature or direct sunlight.

•Avoid dividing chemicals into excessive numbers of small containers to reduce natural evaporation.

•Keep containers sealed to avoid natural evaporation when chemicals are not in use.

•Avoid using chemicals as much as possible. When using chemicals, divide only required amount to a small plate from the container and

use up it.

1-2. EXTERIOR PARTS

Be careful to the following points for plastic parts used in this unit.

• Use a piece of cleaning paper or cleaning cloth for cleaning plastic parts. Avoid using chemicals.

Even if you have to use chemicals to clean heavy dirt, don’t use paint thinner, ketone, nor alcohol.

• Insert the specific screws vertically to the part when installing a plastic part.

Be careful not to tighten screws too much.

1-3. UNLEADED SOLDER

This unit uses unleaded solder.
Boards requiring use of unleaded solder are printed with the lead free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size.)

: LEAD FREE MARK

Be careful to the following points to solder or unsolder.

• Set the soldering iron tip temperature to 350 °C approximately.

If cannot control temperature, solder/unsolder at high temperature for a short time.
Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful!

Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur
such as on IC pins, etc.

• Be sure to control soldering iron tips used for unleaded solder and those for leaded solder so they are managed separately. Mixing

unleaded solder and leaded solder will cause detachment phenomenon.

1-4. SAFETY CHECK-OUT

After correcting the original service problem, perform the following safety checks before releasing the set to the customer.

1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and

bridges.

2. Check the interboard wiring to ensure that no wires are “pinched” or contact high-wattage resistors.

3. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out to the

customer and recommend their replacement.

4. Look for parts which, through functioning, show obvious signs of deterioration. Point them out to the customer and recommend their

replacement.

5. Check the B+ voltage to see it is at the values specified.

6. Flexible Circuit Board Repairing

•Keep the temperature of the soldering iron around 270 °C during repairing.

• Do not touch the soldering iron on the same conductor of the circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering or unsoldering.

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH
MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS

1-5. NOTE FOR REPLACING FUSE ON THE AM-001 BOARD

The caution label for fuse replacing on the AM-001 board is put under the DD-268 board. When replacing the fuse, remove the DD-268 board
and refer to this label.

1-6. DEMAGNETIZATION METHOD

It is easy to receive the influence of the outside magnetism because the slant sensor switch (S624) has the magnet in the inside.
Horizontal and vertical cannot be detected when the influence of magnetism is received, and the display of the LCD panel doesn't change.
Therefore, it is necessary to degauss the screw in the vicinity of the switch.

S624

– AM-001 Board: Side B –

Note it because the user magnetizes set occasionally.

Refer to next page for the demagnetization method.

2-1-6. CCD INCLINATION ADJUSTMENT/REPAIR

Check

1. Use a copy stand, or place a mirror on the wall and adjust the accuracy so that the camera is opposed to its mirror image.

2. Use the AE master lens for inspection.

3. Obtain the tilt angle with the Photoshop, and perform as follows according to the angle:
For the angle above +/–1.0 degree, be sure to repair.
For the angle above +/–0.5 degree and less than +/–1.0 degree, repair according to the user's required level.
For the angle below +/–0.5 degree, re-check and it is within the specification.

Adjustment

1. Remove the eccentric pin stopper. (Fig. 6-1)

2. Check, and adjust the hexagonal eccentric pin. (Fig. 6-2)

*The eccentric pin can be rotated 60 degree (CCD tilt 0.42 degree) in clockwise and counterclockwise directions respectiv ely from

the neutral position.
Adjustment exceeding 60 degree is impossible. (Eccentric pin stopper cannot be installed)
If an image tilts toward the lower right, rotate the eccentric pin 60 degree clockwise.
If an image tilts toward the lower left, rotate the eccentric pin 60 degree counterclockwise.

Eccentric Pin

Eccentric Pin Stopper

Eccentric Pin

Fig. 6-1

Repair (if the adjusting method failed)

1. Disassemble until the CCD Set can be removed.

2. Cut at two bosses for positional reference and directional reference of the CCD holder and the radiation plate. (Fig. 6-3)

3. Attach an insulation sheet to the terminal of CCD Set. (Prevention of short-circuit with CCD holder)

4. Assemble the CCD Set by shifting it by the amount of play
If an image tilts toward the lower right, shift clockwise the CCD Set by the amount of play.
If an image tilts toward the lower left, shift counterclockwise the CCD Set by the amount of play.
The double-sided adhesive tape on the LPF, if shifted by the amount of play, can be corrected in a range of about +/–0.7 degree
maximum.
In this case, however, prepare the service part "Slider Unit: A-1196-100-A" and modify it as described in step 2 above to make it
as a jig, and then shift the LPF on the jig (for prevention of damage to the Steadyshot Set of user's camera).

5. Assemble up to the exterior.

6. Check the tilt following the checking method.

*If not within +/–0.5 degree, replace the "Slider Unit: A-1196-100-A" and recheck.

7. After the repair completed, perform "CCD Aori and Center Adjustment" and "Steadyshot Sensitivity Adjustment".

2-1-10. IRIS RING REMOVAL/INSTALLATION

Removal

Rotate the iris ring clockwise, and remove it at the stop position (iris-in end). (Fig. 10-1)
At this time, do not rotate the iris joint gear of the Aperture Unit.

Installation

1. With the Aperture Unit set in the charge position (see "2-1-12. Aperture Unit Charge Position Setting" ), install it on the front frame set.

*The Aperture Unit has been set in the charge position, if it is not removed.

However, the iris ring must be in the removed state (where the iris joint gear is not rotated).

2. Install the iris ring with it's a punch mark aligned with a line that connects the iris joint gear shaft and the optical axis center. (Fig. 10-1)

2-1-11. APERTURE UNIT INSTALLATION

*The Aperture Unit is supplied by being set in the charge position (initial position), but if this position is disordered when the Aperture Unit is

removed, or if the charge position is to be set again, perform as follows.

*Refer to “2-1-12. Aperture Unit Charge Position Setting” for the confirm method at the charge position.

2-1-12. APERTURE UNIT CHARGE POSITION SETTING

1. Check that the Aperture Unit is in a free state.

2. After confirming that the Aperture Unit is in a free state, rotate the gear by 3 turns.

3. After rotating the gear by 3 turns, set the Aperture Unit where the holes in the gear and the Aperture Unit coincide. This position is the charge
position.

*Refer to “2-1-13. Aperture Unit Free Position Setting” for the setting and the confirm method at the free position.

2-1-13. APERTURE UNIT FREE POSITION SETTING

1. Set the Aperture Unit to a free position once, if the gear was rotated accidentally and the charge position is disordered, or if the charge position
was shifted during disassembly. (Fig. 13-1, 13-2, 13-3)

In a free state, a hole in the gear almost
coincides with a hole in the Aperture Unit.

In a free state, the edge of this spring
will move up and down about 1 mm if
the gear is moved a little.

If the edge of spring is located downward,
rotate the gear in the arrow direction to
search a free position.

* In a free position, the edge of spring is

located upward.

Note: The spring is deformed and cannot

be used if the gear is rotated too
much from a free state.

2-1-14. AF CHARGE UNIT INSTALLATION

1. The lever must be in a free state when the AF Charge Unit is installed. (Fig. 14-1)

Check the lever of the AF Charge Unit for position.
If it protrudes outside, rotate the gear in the arrow direction.

When the lever becomes a free state, it will
retract as shown.

* In this state, install the AF Charge Unit.
