Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type.
CAUTION
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH
MARK 0 ON 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 .
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.

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.

1. SERVICE NOTE
1-3. METHOD FOR COPYING OR ERASING THE DATA IN INTERNAL MEMORY
The data can be copied/erased by the operations on the Setup screen. (When erasing the data, execute formatting the internal memory.)
Note 1: When replacing the SY-144 board, erase the data in internal memory of the board before replacement.
Note 2: When replacing the SY-144 board or the IC202 on the SY-144 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 Stick Duo”.
OK
Cancel
1 Insert a “Memory Stick Duo” having 32 MB or larger capacity.
2 Select [OK] with v on the control butto n, then press z.
The message “All data in internal memory will be copied Ready?” appears.
3 Select [OK] with v, then press z.
Copying starts.
Copying
102_COPY
See the following procedure .
Cancels the copying.
•Use a fully charged battery pack or the AC Adaptor (not supplied). 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.
•You cannot copy individual images.
•The original images in the internal memory are retained even after copying. To delete the contents of the
internal memory, remove the “Memory Stick Duo” after copying, then execute the [Format] command in
(Internal Memory Tool).
•You cannot select a folder copied on a “Memory Stick Duo”.
•Even if you copy data, a (Print order) mark is not copied.
Method for Formatting the Internal Memory
This item does not appear when a “Memory Stick Duo” is inserted in the camera.
The default settings are marked with .
Format
Formats the internal memory.
•Note that formatting irrevocably erases all data in the internal memory, including even protected images.
OK
Cancel
1 Select [OK] with v on the control butto n, then press z.
The message “All data in internal memory will be erased Ready?” appears.
2 Select [OK] with v, then press z.
The format is complete.
See the following procedure .
Cancels the formatting.

Precautions for Replacement of Imager
• If the imager has been replaced, carry out all the adjustments
for the camera section.
• As the imager may be damaged by static electricity from
its structure, handle it carefully like for the MOS IC.
In addition, ensure that the receiver is not covered with
dusts nor exposed to strong light.
When indicating parts by reference number, please
include the board name.
The components identified by mark 0 or dotted line with
mark 0 are critical for safety.
Replace only with part number specified.
Les composants identifiés par une marque 0 sont
critiques pour la sécurité.
Ne les remplacer que par une pièce portant le numéro
spécifie.
