SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0OR DOTTED LINE WITH
MARK 0ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS
LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE
COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS
APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS
PUBLISHED BY SONY.
ATTENTION AU COMPOSANT AYANT RAPPORT
À LA SÉCURITÉ!
LES COMPOSANTS IDENTIFIÉS PAR UNE MARQUE 0SUR LES
DIAGRAMMES SCHÉMATIQUES ET LA LISTE DES PIÈCES SONT
CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT. NE
REMPLACER CES COMPOSANTS QUE PAR DES PIÈCES SONY
DONT LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU
DANS LES SUPPLÉMENTS PUBLIÉS PAR SONY.
Caution
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type.
Dispose of used batteries according to the instructions.
Unleaded solder
Boards requiring use of unleaded solder are printed with the leadfree
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
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40°C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350°C.
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!
• Strong viscosity
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.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.
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.

1. SERVICE NOTE
1-1. PRECAUTION ON REPLACING THE SY-255 BOARD
DESTINATION DATA
When you replace to the repairing board, the written destination data of repairing board also might be changed to original setting.
Start the Adjust Manual in the Adjust Station and execute the “DESTINATION DATA WRITE”.
RESTORE DATA
When you replace to the repairing board, get the data from the former one.
Start the Adjust Manual in the Adjust Station and perform “RESTORE DATA” to get the data.
The data getting for this model is as follows.
• USB SERIAL No.
• AWB standard data input & check, Color reproduction check
• Strobe adjustment
• Wide Limit adjustment
Regarding the PMB Portable
PMB Portable has been written in internal memory.
SY-255 board for service is supplied with written the PMB Portable.
USB SERIAL No.
The set is shipped with a unique ID (USB Serial No.) written in it.
This ID has not been written in a new board for service, and therefore it must be entered after the board replacement.
Start the Adjust Manual in the Adjust Station and execute the “USB SERIAL No. INPUT”.
Angular Velocity Sensor
When you replace to the repairing board, write down the sensitivity displayed on the angular velocity sensor (SE401).
Start the Adjust Manual in the Adjust Station and execute the “Angular velocity sensor sensitivity adj”.

SY-255 BOARD (SIDE B)
Note: The sensor sensitivity of SE401 of SY-255 board is written only repair parts.
1-2. METHOD FOR COPYING OR ERASING THE DATA IN INTERNAL MEMORY
The data can be copied/erased by the operations on the HOME screen. (When erasing the data, execute formatting the internal memory.)
Note 1:When replacing the SY-255 board, erase the data in internal memory of the board before replacement.
Note 2:When replacing the SY-255 board, execute formatting and initialize the internal memory after replacement.
Method for Copying the Data in Internal Memory
Copy
Copies all images in the internal memory to a memory card.
1Insert a memory card with sufficient free capacity into the camera.
2MENU t(Settings) t(Memory Card Tool) t[Copy] t[OK]
tzon the control button
• Use a fully charged battery pack. If you attempt to copy image files using a battery pack with little
remaining charge, the battery pack may run out, causing copying to fail or possibly corrupting the data.
• Images cannot be copied individually.
• The original images in the internal memory are retained even after copying. To delete the contents of the
internal memory, remove the memory card after copying, then format the internal memory ([Format] in
[Internal Memory Tool]).
• A new folder is created on the memory card and all the data will be copied to it. You cannot choose a
specific folder and copy images to it.
Notes
Method for Formatting the Internal Memory or Memory Card media
Format
Formats the memory card or the internal memory. When you use a memory card with this
camera for the first time, it is recommended to format the card using the camera for stable
performance of the memory card before shooting. Note that formatting permanently erases all
data on the memory card, and is unrecoverable. Save precious data on a computer, etc.
1MENU t(Settings) t(Memory Card Tool) or (Internal
Memory Tool) t[Format] t[OK] tzon the control button
• Note that formatting permanently erases all data including even protected images.

1-3. HOW TO WRITE DATA TO INTERNAL MEMORY
Usually, the camera has been set so as to disable the data writing from the PC to the internal memory of the camera.
This setting must be changed temporarily when the data is to be written to the internal memory such as a case after the board replacement.
To change settings is enabled with using the writing enabler tool (Write Enable Tool) on the Adjust Manual is activating from the Adjust
Station.
Data writing method
1) Start the Adjust Manual from the Adjust Station.
2) Click (Write Enable Tool) button.
3) Click “Activate Write Enable Mode” button.
4) Upon completion of the setting change, the following message will be displayed.
5) Return the driver to the original one, and connect the PC to the camera (USB mode: Mass Storage).
6) Write the data read out into the PC to the internal memory of the camera.
7) Disconnect the PC from the camera, and turn off the camera.
Note: By turning off the camera, the write enable setting is reset.
1-4. SELF-DIAGNOSIS FUNCTION
1-4-2. Self-diagnosis Display
When problems occur while the unit is operating, the LCD screen
shows a 4-digit display consisting of an alphabet and numbers, which
blinks at 3.2 Hz. This 5-character display indicates the “repaired
by:”, “block” in which the problem occurred, and “detailed code”
of the problem.
1-4-1. Self-diagnosis Function
When problems occur while the unit is operating, the self-diagnosis
