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 ob vious 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.

SERVICE NOTE
• NOTE FOR REPAIR
Make sure that the flat cable and flexible board are not cracked of
bent at the terminal.
Do not insert the cable insufficiently nor crookedly.
Cut and remove the part of gilt
which comes off at the point.
(Be careful or some
pieces of gilt may be left inside)
When remove a connector, don’t pull at wire of connector.
It is possible that a wire is snapped.
[Discharging of the ST-70 flexible board’s charging
capacitor (C510)]
The charging capacitor (C003) of the ST -70 flexible board is char ged
up to the maximum 300 V potential.
There is a danger of electric shock by this high voltage when the
battery is handled by hand. The electric shock is caused by the
charged voltage which is kept without discharging when the main
power of the unit is simply turned off. Therefore, the remaining
voltage must be discharged as described below.
Preparing the Short Jig
To preparing the short jig, a small clip is attached to each end of a
resistor of 1 kΩ /1 W (1-215-869-11).
Wrap insulating tape fully around the leads of the resistor to prevent
electrical shock.
1 kΩ/1 W
Wrap insulating tape.
Discharging the Capacitor
Short-circuit between the positive and the negative terminals of
charged capacitor with the short jig about 10 seconds.

[Precaution on Replacing the Video Lens or the SY-77
Board]
The DSC-P9 uses the position sensor to detect the zoom position.
Accordingly, the zoom position will v ary if the position data changes
due to the replacement of the video lens or the SY-77 board, thus
causing the video lens to collide against the mechanism end when
the power is turned off.
Though the position data is calibrated at the “Flange Back
Adjustment”, add the following work when making an adjustment
at the replacement of video lens to prevent a collision of video lens.
When Replacing the Video Lens
1) With current video lens assembled, turn the power on, and set
the bit value of Bit0 on Page:9, Address:17 to “0” using the
adjusting remote commander, then turn the power off.
2) Replace the video lens with a new one, turn the power on, and
perform the “Flange Back Adjustment”.
Thus, new position data will be written.
3) After the “Flange Back Adjustment”, return the bit value of Bit0
on Page:9, Address:17 to “1” using the adjusting remote
commander.
When Replacing the SY-77 Board
1) Replace the SY-77 board with a new one, set the mode dial to
“PLAY”, turn the power on, and set the bit value of Bit0 on
Page:9, Address:17 to “0” using the adjusting remote
commander, then turn the power off.
2) Set the mode dial to “CAMERA”, turn the power on, and
perform the “Flange Back Adjustment”.
Thus, new position data will be written.
3) After the “Flange Back Adjustment”, return the bit value of Bit0
on Page:9, Address:17 to “1” using the adjusting remote
commander.
[Note in Lens Frame Installation]
When tightening a screw , have both sides of the lens b lock assemb ly
so as not for the load to depend.

µF. 50 V or less are not indicated e xcept 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 and waveform)
•Voltages and waveforms are measured between the
measurement points and ground when camera shoots
color bar chart of pattern box. They are reference values
and reference waveforms.
(VOM of DC 10 MΩ input impedance is used)
•Voltage values change depending upon input
impedance of VOM used.)

CCD IMAGER
Precautions for Replacement of CCD Imager
• The CD-397 board mounted as a repair part is not equipped
with a CCD imager.
When replacing this board, remove the CCD imager from the
old one and mount it onto the new one.
• If the CCD imager has been replaced, carry out all the
adjustments for the camera section.
• As the CCD 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.
