SAFETY CHECK-OUT
After correcting the original problem, perform the following
safety check before return the product to the customer.
1. Check the area of your repair for unsoldered or poorly
soldered connections. Check the entire board surface
for solder splasher 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, though 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. Make leakage - current measurements to determine
that exposed parts are acceptably insulated from the
supply circuit before returning the product to the
customer.

RoHS lead-free compliance
Because this product is RoHS lead-free compliant, use the designated after-sales parts and the designated lead-free solder
when performing repairs.
<Background & Overview>
With the exception of parts and materials expressly excluded from the RoHS directive (*1), all the internal connections and
component parts and materials used in this product are lead-free compliant (*2) under the European RoHS directive.
*1: Excluded items (list of the main lead-related items)
• Lead included in glass used in fluorescent tubes, electronic components and cathode-ray tubes
• Lead in high-melting-point solder (i.e. tin-lead solder alloys that contain 85% lead or more)
• Lead in ceramic electronic parts (piezo-electronic devices)
• Mercury contained in fluorescent tubes is also excluded.
*2: Definition of lead-free
A lead content ratio of 0.1 wt% or less in the applicable locations (solder, terminals, electronic components, etc.)
<Reference>
RoHS: The name of a directive issued by the European Parliament aimed at restricting the use of
certain designated hazardous substances included in electrical and electronic equipment.
Designated substances (6): Lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBBs) and
polybrominated diphenyl ether (PBDE)
<Lead-free soldering>
When carrying out repairs, use a designated lead-free solder, bearing in mind the differing work practices for conventional
solder (eutectic) and lead-free solder.
Differences in the soldering work for lead-free and eutectic solder
When the soldering work practices for eutectic solder and lead-free solder are compared, the main differences are as shown
below. In particular, when lead-free solder is used, the solder tends to be less workable than when eutectic solder is used.
Accordingly, the soldering techniques used must take that into account.
Difference
The solder starts melting later.
1
Poor wetting
2
Solder feed rate is difficult to control.
3
Wetting the insides of through holes is especially
4
difficult.
5
During repairs (or modifications) removing solder
from inside through holes is difficult.
6
There is serious carbonization of the soldering iron.
The surface is not glossy.
7
The initial melting point of lead-free solder is high, so you
have to get used to it.
Move the tip of the soldering iron around to heat the entire
connection to the melting temperature and assist wetting.
Use the solder (wire) diameter and soldering iron that are
best suited to connection being soldered.
First apply solder to the area immediately around the
through hold and then feed the solder into the hole.
Use a suitable wicking wire (with a suitable method and
heating) and a suction tool.
Either put solder onto the soldering iron tip after completing
the work, or turn the iron off frequently.
Learn to recognize the appearance of the surface.

FinePix F460 Service Manual
Setting temperature during lead-free soldering
• Lead-free solder melting temperature
The melting point of eutectic (Sn-Pb) solder is 183°C, while the melting point of lead-free solder (Sn-Ag-Cu) is 30°C higher
at 220°C.
• Soldering iron tip temperature
The temperature setting for the soldering iron used should be such that the tip of the soldering iron is at the correct
bonding temperature for the connection. This temperature is normally set at around 100°C higher than the melting point of
the solder.
However, the actual temperature should take into account the shape and size of the soldering iron tip, the heat tolerance
of the connection and the workability of that temperature.
• Correct bonding temperature
The correct bonding temperature refers not to the temperature of the heat source, but to the bonding temperature that will
give the best bond strength.
Precautions when soldering with lead-free solder
• Soldering iron maintenance
Because of the high soldering iron temperature in lead-free soldering, there is rapid carbonization of the flux adhering to
the tip of the soldering iron.
(1) Always cover the tip of the soldering iron with solder when it is not being used.
(2) If the tip is black from carbonization, wipe it gently with a paper towel soaked in alcohol until the solder will wet.
• Uniform heating of the board and components
To ensure that the lead-free solder wets the entire surface of the pattern and the lands despite its poor wetting
characteristics, you must move the tip of the soldering iron over a wide area to raise the temperature of the entire
connection.
Soldering iron
A soldering iron with a temperature control is best.

FinePix F460 Service Manual
1. General
1-2. Explanation of Terms
EV: A number denotes Exposure Value. The EV is determined by the brightness of the subject
and sensitivity (speed) of the film or CCD. The number is larger for bright subjects and
smaller for dark subjects. As the brightness of the subject changes, a digital camera
maintains the amount of light hitting the CCD at a constant level by adjusting the aperture
and shutter speed.
When the amount of light striking the CCD doubles, the EV increases by 1. Likewise, when
the light is halved, the EV decreases by 1.
Frame rate (fps): The frame rate refers to the number of images (frames) that are photographed or played
back per second. For example, when 10 frames are continuously photographed in a 1-
second interval, the frame rate is expressed as 10 fps.
For reference, TV images are displayed at 30 fps (NTSC).
JPEG: Joint Photographic Experts Group
A file format used for compressing and saving color images. The higher the compression
rate, the greater the loss of quality in the decompressed (restored) image.
Motion JPEG: A type of AVI (Audio Video Interleave) file format that handles images and sound as a
single file. Images in the file are recorded in JPEG format. Motion JPEG can be played
back by QuickTime 3.0 or later.
Smear: A phenomenon specific to CCDs whereby white streaks appear on the image when there
is a very strong light source, such as the sun or reflected sunlight, in the photography
screen.
WAVE: A standard format used on Windows systems for saving audio data. WAVE files have the
“.WAV” file extension and the data can be saved in either compressed or uncompressed
format. Uncompressed recording is used on this camera.
WAVE files can be played back on a personal computer using the following software:
Windows: MediaPlayer
Macintosh: QuickTime Player
* QuickTime 3.0 or later
White Balance: Whatever the kind of the light, the human eye adapts to it so that a white object still looks
white. On the other hand, devices such as digital cameras see a white subject as white by
first adjusting the color balance to suit the color of the ambient light around the subject.
This adjustment is called matching the white balance.
Exif Print: Exif Print Format is a newly revised digital camera file format that contains a variety of
shooting information for optimal printing.

3-1-3. IC901, IC902 (V driver) and IC905 (H driver)
The H driver and V driver are necessary to generate the
clocks that drive the CCD (vertical register transfer clock,
horizontal register transfer clock and electronic shutter
clock). IC 901 and IC902 comprise the V driver, XV1-XV6
output from IC101 comprises the vertical register transfer
clock, and XSG is superposed in IC901 and IC902 to
generate a 3-value pulse. The XSUB output by IC101 serves
as the clearing pulse for the electronic shutter. The H driver
is built into IC905 and the clocks for H1, H2 and RG are
created by IC905.
3-1-4. IC905 (CDS, AGC, A-D conversion)
Video signals output from the CCD are input via pin 27 on
IC905. Inside the IC are a sampling hold block, AGC block
and A-D conversion block. The sampling phase and AGC
amplifier settings are specified using serial data to pin 32.
The video signals are A-D converted and output as 10-bit data.

operation
3-2-1. Circuit Description
Digital clamp
The black levels for the CCD output data are evened up
across the line by subtracting the averaged value for the
optical black sections of the CCD from the subsequent data.
The average value for the optical black sections of the CCD
is obtained by multiplying the value for the previous line by a
coefficient k and multiplying the value for the current line by a
coefficient k-1 and then taking the sum of the multiples.
Signal processor
γγ
γ (gamma) correction circuit: γ (gamma) correction is
γγ
performed to ensure that there is a linear relationship
between the optical input to the camera and the optical
output of the screen receiving the image.
Color signal generation circuit: This circuit converts the
CCD data to R, G and B signals.
Matrix circuit: This circuit uses the R, G and B signals to
generate Y, R-G and B-G signals.
Horizontal/vertical aperture circuit: This circuit generates
the aperture signal.
3-2-2. Outline of Operation
When the shutter is released, the microprocessor sends a
reset signal and a serial signal (TAKE A PICTURE
instruction) to the ASIC and CPU and operation begins.
When the TG/SG drives the CCD, the image data passes
through A-D conversion and CDS and is sent to the ASIC as
12-bit data. The received (input) data is then input to SDRAM
via the digital clamp.
This data is used to calculate the AF, AE, AWB, shutter and
AGC values, and then 3 exposures are normally taken to
obtain the best possible image. The data for the images
stored in SDRAM is loaded into the CPU and the colors are
generated. Each pixel in the R, G and B data is interpolated
from the surrounding data to generate the R, G and B pixel
data. After AWB and γ (gamma) correction, a matrix is
generated and aperture compensation is applied for the Y
signal. The resulting data is then subjected to JPEG
compression and recorded onto card memory (xD-Picture
card). When the data is output to an external device, the data
is fetched from memory and output serially via USART. When
the image is played back on an LCD or monitor, the data is
transferred from memory to SDRAM, expanded into the
SDRAM display area and then displayed.
AE/AWB/AF calculation circuit
This circuit calculates the AE and AWB values by dividing the
screen into 64 zones and calculates the AF value by dividing
the screen into 6 zones.
SDRAM controller circuit
This circuit outputs the address, RAS, CAS and AS used for
SDRAM control. This circuit also refreshes the SDRAM.
Communication control
SIO: This is the interface with the 8-bit microprocessor.
SIO for LCD, PWM and PIO: This makes it possible to
switch between PWM output and individual I/O in 8-bit
parallel I/O.
TG/SG
This controls and generates timing for the 5-megapixel CCD.
Digital encoder
This generates chroma signals from the color difference
signals.
3-2-3. LCD Block
The LCD display circuit is located on the CP1 board and
includes its own power supply circuit.
Signals from the ASIC are input directly to the LCD as 8-bit
digital signals and are converted to RGB signals by the driver
circuit built into the LCD. The LCD is a 3-wire serial device
and controls parameters such as the brightness and image
quality.
The larger the difference in potential between VCOM
(common terminal voltage: AC) and R, G and B, the more the
LCD elements close and the display darkens. Conversely,
the smaller the potential difference, the more the LCD
elements open and the display brightens. In addition to the
video signals, timing pulses are also input directly to the LCD
from the ASIC.

3-2-4. Lens Drive Block
Focus drive
The focus is operated by the focus stepping motor, which is
driven (AFSPM (1) +A, AFSPM (2) -A, AFSPM (3) +B,
AFSPM (4) -B) by the motor driver (IC951) in response to 4
control signals (FIN1, FIN2, FIN3 and FIN4) output by the
ASIC (IC101). The focus reference position is detected by a
photo-interrupter (AFPI_E) inside the lens unit.
Zoom drive
The zoom is operated by the zoom DC motor, which is driven
(ZM (+), ZM(-)) by the motor driver (IC951) in response to 2
control signals (ZIN1 and ZIN2) output by the ASIC (IC101).
The zoom reference position is detected by a photo-reflector
(ZMPR_E) inside the lens unit. The zoom position is also
acquired using a count kept for a photo-interrupter (ZMPI_E)
inside the lens unit.
Shutter drive
The mechanical shutter is opened and closed by a fixedcurrent drive (SHUT (+), SHUT (-)) from the motor driver
(IC951) in response to 2 control signals (SIN1 and SIN2)
output by the ASIC (IC101).
Aperture (ND) drive
The aperture is operated by the ND filter motor, which is
driven (IRIS (+), IRIS (-)) by the motor driver (IC951) in
response to 2 control signals (IIN1 and IIN2) output by the
ASIC (IC101).
3-3. Description of PWA power
circuit operation
3-3-1. Outline
The power circuit consists primarily of the following blocks:
• Switching power controller (IC501)
• VDD 5V power output (L5001)
• VDD 3V (digital 3.25-volt) power output (L5008)
• VDD 1.2V (digital 1.2-volt) power output (L5007)
• CCD 15.0V power output (L5003)
• CCD -7.5V power output (L5005)
• LCD backlight power output (L5002)
• CCD 3.45V output (IC502)
• LCD 12V output (IC504)
Switching power controller (IC501)
Built into this controller are the basic circuits that drive and
control the 8 types of current used in the DSC. These
currents are comprised of the channels (CH) for SU, M, SD,
BST, INV, LED, AFE and AUX. On this model, CH AFE and
CH AUX are not used. The channel-to-output
correspondence is as shown below.
• SU - VDD 5V
• M - VDD 3V
• SD - VDD 1.2V
• BST - CCD 15.0V
• INV - CCD -7.5V
• LED - LCD backlight
The output from each type is fed back to IC501.
IC501 monitors the feedback voltages and performs PWM
control so as to maintain the designated voltages for each
channel.
Short-circuit protection
When a short-circuit of 100 msec or longer occurs on any of
the outputs, IC501 detects the short-circuit and sets all
output to OFF. Operation can be recovered by re-imposing
control via the ONSU terminal (pin 46).
VDD 5V power output
The switching power controller IC501 generates VDD 5V by
stepping up and controlling the voltage supplied from the
battery. The VDD current is the drive power supply used by
IC501 and is fed back to IC501 (pin 42) and subjected to
PWM control. The VDD 5V power output is also the supply
source for the VDD 3V and CCD 3.45V circuits.
VDD 3V power output
IC501 generates the VDD 3V power output by stepping down
and controlling the VDD 5V power output. VDD 3V is fed
back to IC501 (pin 2) and subjected to PWM control.

3. Schematics
FinePix F460 Service Manual
VDD 1.2V power output
IC501 generates the VDD 1.2V power output by stepping
down and controlling the power supplied from the battery.
VDD 1.2V is fed back to IC501 (pin 12) and subjected to
PWM control.
CCD 15V power output
IC501 generates the CCD 15V power output by stepping up
and controlling the power supplied from the battery. CCD
15V is fed back to IC501 (pin 26) and subjected to PWM
control. The CCD 15V power output is also the supply source
for the LCD 12V circuit.
CCD -7.5V power output
IC501 generates the CCD -7.5V power output by reversing
the polarity and controlling the power supplied from the
battery. CCD -7.5V is fed back to IC501 (pin 25) and
subjected to PWM control.
LCD backlight power output
A set current is output to the backlight LED for the LCD.
The backlight power output is fed back to IC501 (pin 37) and
subjected to PWM control to ensure that the current flowing
to R5024 is constant.
CCD 3.45V power output
Series regulator IC502 generates the CCD 3.45V power
output by stepping down the VDD 5V output.
LCD 12V power output
Series regulator IC504 generates the LCD 12V power output
by stepping down the CCD 15V output.
3-4. Description of ST1 flash
circuit operation
3-4-1. Charging circuit
When UNREG power is supplied to the charging circuit and
the CHG signal from the microprocessor is Hi (3.3 volt), the
charging circuit starts operating and charges the main
electrolytic capacitor with direct current at high voltage. If the
CHG signal is Lo (0 volt), the charging circuit does not
operate.
Power switch
When the CHG signal is Hi, IC542 is set to ON and charging
starts.
Power filter
C5407 acts as a power filter that smoothes out current
ripples caused by oscillation transformer switching.
Oscillation circuit
This circuit generates an AC voltage (pulses) for stepping up
the DC low-voltage UNREG power supply. The oscillation
circuit generates drive pulses with frequencies from
approximately 50 KHz to 100 KHz. Because the circuit is
self-oscillating, the oscillation frequency varies depending on
the drive conditions.
Oscillation transformer
The oscillation transformer converts the low-voltage AC
current generated by the oscillation control circuit to a highvoltage AC current.
Rectifier circuit
This circuit rectifies high-voltage AC current occurring on the
secondary side of T5401 so that it becomes high-voltage DC
current and stores the charge in the main electrolytic
capacitor (C5412).
24
Voltage monitor circuit
This circuit is used to maintain the voltage stored in C5412 at
a set level. Once the charging voltage has been divided and
reduced by R5405 and R5406, it is output as the monitor
voltage VMONIT.
When the VMONIT voltage reaches the stipulated value, the
CHG signal is set to Lo and charging stops.

3-4-2. Flash Circuit
When an FLCLT signal is input to this circuit from the ASIC
expansion board, the flash fires.
Flash control circuit
When a Hi FLCLT signal is input to the flash control circuit,
Q5409 is set to ON and the flash is readied for firing. If the
FLCLT signal is Lo, firing stops.
Trigger circuit
When Q5409 is set to ON by the FLCLT signal and the flash
is ready to fire, at the same time a high-voltage pulse of
several kilovolts is generated by the trigger coil and applied
to the flash unit.
Flash element
When the high-voltage pulse from the trigger circuit is
applied to the flash unit, the current flows into the flash
element and the flash fires.
