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.
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

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. NOTA DE SERVIÇO
1-1. MÉTODO PARA A COPIAR OU APAGAR O DADO DA MEMÓRIA INTERNA
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-150 board, erase the data in internal memory of the board before replacement.
Note: 2 When replacing the SY-150 board or the IC202 on the SY-150 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 button, 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 Nickel-Metal Hydride battery or the AC Adaptor (not supplied). If you attempt to
copy image files using a batteries with little remaining charge, the batteries 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 app ear when a “Memory Stick Duo” is inserted in the camera.
The default settings are marked with .
Format
Formats the internal memo r y.
• 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 button, 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.
• PROCESS AFTER FIXING FLASH ERROR
When “FLASH error” (Self-diagnosis Code E : 91 : ** ) occurs, to prevent any abnormal situation caused by high voltage, setting of the
flash is changed automatically to disabling charge and flash setting.
After fixing, this setting needs to be deactivated. Flash error code can be initialized by the operations on the Setup screen.
Method for Initializing the Flash Error Code
Initialize
Initializes the setting to the default setting.
OK
Cancel
1 Select [OK] with v on the control button, then press z.
The message “Initialize all settings Ready?” appears.
2 Select [OK] with v, then press z.
The settings are reset to the default setting.
Make sure that the power is not disconnected during resetting.
See the following procedure.
Cancels the resetting.
THIS NOTE IS COMMON FOR SCHEMATIC DIAGRAMS
(In addition to this, the necessary note is printed in each block)
(For schematic diagrams)
• All capacitors are in µ F unless otherwise noted. pF : µ
Link
µ F. 50 V or less are not indicated except for electrolytics
and tantalums.
• Chip resistors are 1/10 W unless otherwise noted.
kΩ=1000 Ω, MΩ=1000 kΩ.
• Caution when replacing chip parts.
New parts must be attached after removal of chip.
Be careful not to heat the minus side of tantalum
capacitor, Because it is damaged by the heat.
• Some chip part will be indicated as follows.

(Measuring conditions voltage)
• Voltages are measured between the measurement
points and ground when camera shoots color bar chart
of pattern box. They are reference values.
(VOM of DC 10 MΩ input impedance is used)
• Voltage values change depending upon input
impedance of VOM used.)
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.
