Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type.

CAUTION

DSC-S40

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.

ATTENTION AU COMPOSANT AYANT RAPPORT

À LA SÉCURITÉ! LES COMPOSANTS IDENTIFÉS P AR UNE MARQUE 0 SUR LES DIAGRAMMES SCHÉMA TIQUES ET LA LISTE DES PIÈCES SONT CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT. NE REMPLACER CES COMPOSANTS QUE PAR DES PIÈSES SONY DONT LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU DANS LES SUPPÉMENTS PUBLIÉS PAR SONY.

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.

1-1. NOTE FOR REPAIR

When installing a connector, don’t press down at wire of connector. It is possible that a wire is snapped.

1. SERVICE NOTE

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.

1-2. DISCHARGING OF THE ST-116

BOARD’S CHARGING CAPACITOR (C901)

The charging capacitor (C901) of ST -116 board is charg ed up to the maximum 300 V potential. There is a danger of electric shock by this high voltage when the capacitor 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.

R:1 kΩ/1 W (Part code: 1-215-869-11)

1-3. THE CAUTIONS AT THE TIME OF LENS BLOCK HANDLING

In case you deal with a lens block, be careful of the following things.

CD-575 flexible board is integrated with the lens block. Do not touch or separate the CD board. CD-575 flexible board becomes only exchange by lens block.

Have the portion of upper and lower arrows with two fingers.

Touch the flexible board of motor side recklessly or don’t bend it., because the mounted chip parts could be peeled if the flexible board is curved.

1-5. 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-116 board, erase the data in internal memory of the board before replacement. Note: 2 When replacing the SY-116 board or the IC1401 on the SY-116 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”.

Cancel

1 Insert a “Memory Stick” having 32 MB or larger capacity. 2 Select [OK] with v on the control button, then pre ss 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

• Use batteries with enough capacity or the AC Adaptor (not supplied). If you attempt to copy image files using batteries with little remaining capacity, 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” after copying, then execute the [Format] command in Internal Memory Tool.

• You cannot select a folder copied on a “Memory Stick”.

• The setting of (Print order ) marks is not copied even when you copy data.

See the following procedure. Cancels the copying.

Method for Formatting the Internal Memory

Format

Formats the internal memory.

• Note that formatting irrevocably erases all data in the internal memory, including even protected images.

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 com

lete.

See the following procedure. Cancels the formatting.

1-6. 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.

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.
