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 F650 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.

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 (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 comprise the V driver, XV1-XV6 output from
IC101 comprises the vertical register transfer clock, and XSG
is superposed in IC901 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 12-bit
data.

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 6-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 PWB and
consists of the LCD driver IC (IC171) and its peripheral
circuits.
Signals from the ASIC, consisting of 8-bit digital signals,
serial control signals and synchronization control signals, are
input to the LCD driver IC.
These signals are then converted to RGB signals by the LCD
driver IC. The serial control signals are used to control
factors such as brightness and image quality.
The larger the potential differences between the COM
signals (common electrode voltage: AC fixed) and the R, G
and B signals, the greater the LCD pixel closure and the
darker the display. Conversely, the smaller the potential
difference, the less the LCD pixel closure and the brighter the
display.

3-2-4. Lens Drive Block
Focus drive
The 8-bit serial data signals (L_DATA along with L_STB,
FCLK, L_ST and L_SCLK) output from the ASIC (IC 101) are
driven by the motor driver (IC951) and in turn drive the
stepping motor used for focusing (AF_M0, AF_M1, AF_M2
and AF_M3).
The focus reference position is detected by a photointerrupter (AF_HOME) in the lens block.
Zoom drive
The signals (ZIN1 and ZIN2) output from the ASIC (IC101)
are subjected to a constant-current drive (ZM(+) and ZM(-))
from the motor driver (IC 951) and in turn drive the DC motor
for the zoom.
The zoom reference position is detected by a photo-reflector
(ZM_HOME) in the lens block. To ascertain the zoom
position, the ASIC (IC101) counts the output from a photointerrupter (ZM_ENC) in the lens block.
Shutter drive
The shutter drive signals (SIN1 and SIN2) output from the
ASIC (IC101) are subjected to a constant-current drive (SD1
and SD2) from the motor driver (IC 951) and in turn open
and close the mechanical shutter.
Aperture drive
The 8-bit serial data signals (L_DATA along with L_STB,
ICLK, L_ST and L_SCLK) output from the ASIC (IC 101) are
driven by the motor driver (IC951) and in turn widen or
narrow the aperture (ST1, ST2, ST3 and ST4).

• LCD 3.0V (L) power output (IC505)
Switching power controller (IC501)
The basic circuitry required to control the PWM switching
regulator power supply has 7 internal channels, of which 6
are used. One more channel is built into the linear regulator,
and this channel is also used.
These are CH1 (BOOST 5.0V), CH2 (digital VDD 3V), CH3
(digital VDD 1.2V), CH4 (analog -7.5V), CH5 (analog 12V
(A)) and CH7 (backlight).
The power supply output feedback from CH1 (BOOST 5.0V),
CH2 (digital VDD 3V), CH3 (digital VDD 1.2V), CH4 (analog -
7.5V) and CH5 (analog 12V (A)) is received and used to vary
the PWM duty so that the respective set voltages are
maintained.
For the backlight power supply (CH7), the end-to-end voltage
for the output resistance is used as feedback to regulate the
constant current so that the set current is maintained.
Short-circuit protection
If output is short-circuited for an interval determined by the
capacitor connected to IC501 (pin 1), all output is turned off.
To recover operation, resend the control signal (P ON).

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).
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 R5402, R5405, R5406 and R5412, 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 the FLCLT signal input to the flash control circuit is
"Hi", Q5409 is set to ON and flash firing commences. When
the FLCLT signal is "Lo", flash 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.

3-5-4. Power Supply Control
An 8-bit microprocessor controls power to the entire system. This description covers the starting and stopping of the power
supply.
When the battery is installed, IC501 is activated and generates 5.0 volts. This power supply is regulated to 3.2 V by IC302 and
supplied to a microprocessor (IC301). Even when the power switch is set to OFF, clock counting and key scanning continues
in readiness for the next activation.
When the power is turned off, the microprocessor stops the main clock (4 MHz) and runs on the sub-clock (32.768 kHz).
When the power is turned off, the supply voltage switching function for the IC302 microprocessor runs the microprocessor in
power-saving mode.
When the battery supplying power is removed, IC302 switches the power supply for the 8-bit microprocessor to the backup
battery and the microprocessor runs in low-power mode. In this situation, the microprocessor stops the main clock and runs
the clock only using the sub-clock used for keeping the time.
(The backup battery is charged for 10 hours after the battery is fitted.) When the power switch is set to ON, the
microprocessor performs activation processing. First, it sets PON (pin 30) to High to activate the power circuit. Roughly 97.6
ms after setting PON to High, it specifies the external port setting for the ASIC. This external port setting is then used to set
the ASIC internal operating frequency and control oscillation. The microprocessor also initiates communication with the ASIC
and checks that the system is capable of running.
When the LCD panel lights, LCDON (pin 42) is set to High and the panel power supply is activated. BLON (pin 43) is then set
to High to activate the backlight power supply.
When the power is turned off, the lens retracts, PON, LCDON and BLON are all set to Low and the power supply to the
system stops. The microprocessor stops main clock oscillation and the operation mode switches to clock oscillation.
