CAUTION

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 .

1. Check the area of your repair for unsoldered or poorly-soldered

2. Check the interboard wiring to ensure that no wires are

3. Look for unauthorized replacement parts, particularly

4. Look for parts which, through functioning, show ob vious signs

5. Check the B+ voltage to see it is at the values specified.

6. FLEXIBLE Circuit Board Repairing

SAFETY-RELATED COMPONENT WARNING!!

SAFETY CHECK-OUT

After correcting the original service problem, perform the following safety checks before releasing the set to the customer.

of deterioration. Point them out to the customer and recommend their replacement.

• 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.

1-2. 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

DSC-N1_L2

Initialize

Initializes the settin g to the default setting. The message “Initialize all settings Ready?” appears.

Cancel

• Make sure that the power is not disconnected during resetting.

Resets the settings to the default se tting. Cancels the resetting.

1-3. METHOD FOR COPYING OR ERASING THE DATA IN INTERNAL MEMORY

(INTERNAL MEMORY/ALBUM/MUSIC)

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-138 board, erase the data in internal memory of the board before replacement. Note: 2 When replacing the SY-138 board or the IC401 on the SY-138 board, execute formatting and initialize the internal memory after

replacement.

Method for Copying the Data in Internal Memory or Album

Copy

Copies all images in the internal memory or the Album to a “Memory Stick Duo”.

Internal Memory

Album

1 Insert a “Memory Stick Duo” having 32 MB or lar ge r cap acit y. 2 Touch media ( [Int erna l Memory] or [Album]) you want to copy the image files from.

The messag e “All data in internal memory will be copied (All data in A lbum will be copied) Ready?” appears.

3 Touch [OK ].

Copying starts.

Copying

102_COPY

Copies the image files in the internal memory. Copies the image files in the Album.

• 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 or Album are retained even after copying. To delete the

contents of the internal memory or Album, execute the [Format] command in (Internal Memory)

or (Album).

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

• Even if you copy data, a (Print order) mark is not copied.

• When copying from the Album, the image protection setting is not copied.

• When playing back images in the Album, the order of images displayed on the screen may be different

from that of images copied on the “Memory Stick Duo”.

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.

The message “All data in internal memory will be erased Ready?” appears.

Cancel

Formats the internal memory. Cancels the formatting.

Method for Formatting the Album

Format

Formats the Album.

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

The message “All data in Album will be erased Ready?” appears.

Cancel

Formats the Album. Cancels the formatting.

DSC-N1_L2

Method for Formatting the Music

Format Music

If you cannot play back a Music file for the Slide Show, the Music file might be corrupted. If this happens, perform [F ormat Music], the n transfe r the music by [Do wnload Music] using th e supplied “Music Transfer” software.

•If you format the write-in-area of the Music file, all Music files are deleted and cannot be restored.

The message “All data will be erased Ready?” appears.

Cancel

Formats the Music files. All data other than Music files remain as it is.

Cancels the formatting.

• 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.

• When remove a connector, dont’ pull at wire of connector. It is possible that a wire is snapped.

• When installing a connector, dont’ press down at wire of connector. It is possible that a wire is snapped.

• Do not apply excessive load to the gilded fle xible board.

Cut and remove the part of gilt which comes off at the point. (Be careful or some pieces of gilt may be left inside)

DISCHARGING OF THE ST-129 FLEXIBLE BOARD’S CHARGING CAPACITOR (C901)

The charging capacitor (C901) of the ST-129 FLEXIBLE board is charged 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.

Note: High-voltage cautions

Discharging the Capacitor

Short-circuit between the two points with the short jig about 10 seconds.

1 kΩ/1 W

Wrap insulating tape.
