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.

1. Power

1-1. Power cuts out in mid-operation.

Fault details: In both Camera mode and Playback mode, the camera sometimes emitted a short beep

and then turned off. Pressing lightly on the battery cover caused this to happen.

Analysis results: Vibration or stress applied to the camera body caused the battery cover detection switch

(SW401) to malfunction and turn the camera off.

Repair details:

The solution was to fit a replacement DCST PWB ASSY with modifications to the SW401 and its surrounding
circuits, or to replace the individual parts (See Bulletin GS-2005-022).

2. LCD

2-1. LCD monitor does not show images

Fault details: The LCD monitor display was abnormal. The display was white and no images appeared.
Analysis results: The LCD flexible cable was pushed onto connector CN501 but was not locked in place.

We simply locked the cable in place and confirmed that images were displayed correctly.

Repair details:

Relocked connector CN501.

2-2. LCD monitor does not show images

Fault details: LCD monitor does not show images. No image appears.
Analysis results: Rectified by replacing the LCD CONST.

Repair details:

Replace the LCD CONST.

2-3. LCD monitor cracked

Fault details: The LCD monitor was cracked.
Analysis results: A crack ran up from the lower-left corner of the LCD. The corresponding section of the R

panel showed impact marks and a depression towards the LCD panel, indicating that the
damage was caused by external impact or pressure.

Repair details:

Replace the LCD CONST.

3. Lens

3-1. Zoom error displayed

Fault details: A zoom error was displayed. The lens was distorted or dislodged.
Analysis results: The lens was damaged and bent. This appeared to be lens damage caused by an impact

while the lens was extended.

Repair details:

Replace the LCD CONST

3-2. Camera stops working after the lens extends

Fault details: When the camera was turned on in photography mode, it stopped working after the lens

extended. The camera also would not turn off.

Analysis results: Replacing the DCST PWB restored normal camera operation. We observed large amounts

of solder scrap spattered around DCST PWB D411, L404 and C406 (mostly on the CCD­6V power supply circuit) with some short-circuiting.

Repair details:

Replace the DCST PWB

6

FinePix F455 TROUBLESHOOTING GUIDE

3-3. Lens barrier fails to open

Fault details: Lens barrier fails to open.
Analysis results: There was a thin film on the upper and lower blades of the lens barrier that caused the

blades to catch.

Repair details:

Replace the LENS CONST.

3-4. Lens barrier fails to open

Fault details: Lens barrier fails to open.
Analysis results: Fine dust had got into the barrier mechanism. Large amounts of the same type of dust

were also observed on the lens surface, indicating that the dust adhered to the lens
while the camera was being used.

Repair details:

Replace the LENS CONST.

4. Operation

4-1. The mode does not change

Fault details: The camera does not switch to still photography mode when still photography mode is

selected.

Analysis results: The mode could not be changed because the lever on KEY PWB SW801 was missing.

(SW801 remains fixed in the center position (open = Movie mode).

Repair details:

Replaced SW801 on the KEY PWB ASSY.

4-2. The mode does not change

Fault details: The camera does not switch to still photography mode when still photography mode is

selected.

Analysis results: Because the KEY PWB locking screw (SCREW_BT2M1.7 X 3.0) was not fitted, KEY PWB

SW801 was floating loose on the PWB so that the lever did not engage with the mode
button fitting (MODE PSP) and SW801 did not change.

Repair details:

Attached SCREW_BT2M1.7 X 3.0.

4-3. The mode does not change

Fault details: The mode does not change.
Analysis results: The switch was unstable, since simply applying the tester to measure the voltage at pin 10

on CN201 for the mode signal line sometimes switched the camera to Movie mode. This
indicated a high impedance state such as a break in the same signal line in the KEY FPC.
Replacing the KEY PWB ASSY rectified the problem.

Repair details:

Replace the KEY PWB ASSY.

4-4. None of the control buttons on the back of the camera work

Fault details: None of the control buttons on the back of the camera work.
Analysis results: Connector CN201 on the MAIN PWB was broken and the KEY FPC was dislodged.

Breaks and peeling in the copper film on the LCD indicate that the damage is due to the
camera being disassembled by someone other than Fujifilm.

Repair details:

Replace the MAIN PWB ASSY.

5. Other

5-1. Card error displayed

Fault details: Card error displayed.
Analysis results: When the media was inserted and the camera was turned on, a card error was displayed.

The solder on pin 18 (D7) in card socket CN401 on the DCST PWB ASSY was found to be
dislodged. We confirmed that the camera functioned normally after the pin was resoldered.
Presumably, imperfect soldering produced a false connection and after the camera was
shipped the connection was dislodged while the camera was being used.

Repair details:

Resoldered pin 18 (D7) in card socket CN401 on the DCST PWB ASSY.

5-2. The flash makes a sputtering noise when it fires

Fault details: The flash makes a sputtering noise when it fires.
Analysis results: The solder for the xenon tube in the flash was dislodged. This caused problems such as

discharging noises, sparking and vapor emissions under the strong current used when the
flash fired. Resoldering restored normal operation.

Repair details:

Resoldered the xenon tube in the flash.

5-3. The cradle remains in USB mode and will not switch to PLAY

Fault details: The cradle remains in USB mode and will not switch to PLAY.
Analysis results: The mode could not be changed because the boss on the USB <=> PLAY switch (SW2)

was snapped off.

Repair details:

Replace the CRADLE.
