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.

NOTE FOR REPAIR

2. DISASSEMBLY

• 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-133 BOARD’S CHARGING CAPACIT OR (C901)

The charging capacitor (C901) of the ST-133 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.

1 kΩ/1 W

Note: High-voltage cautions

Discharging the Capacitor

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

Part Number Part Name Quantity 1 2-673-650-01 Ring (A), Ornamental 1 2 2-673-652-01 Barrier Assy 1 3 2-673-651-01 Tapping screw (B1.2×4) 2

Tools used

Torque driver Soldering iron Weight about 60g Adhesive tape (ornamental ring fixed) (2-677-885-01)

2-2-1. PEEL OFF OLD ORNAMENTAL RING A

The Ornamental Ring A has adhered to the Barrier Assy strongly and accordingly, use a soldering iron to weaken the adhesive force. Heat four circled portions with the soldering iron. Heating temperature is about 300ºC. Beware of a burn since the entire Ornamental Ring becomes hot. * As the adhesive force of Ornamental Ring A is considerably large, the forced peeling will damage the group-1 frame.

Insert the tip of tweezers, etc. into a notch of the group-1 frame and prize the ring. * Take extreme care so as not to damage the coated surface of the group-1 frame. In case of difficult peeling, heat the ring again with the soldering iron. If this re-heating failed, it may be advisable that the ring be peeled while heating the portions 1 → 2 in the under figure one by one sequentially.

* Discard the removed Ornamental Ring A.

1 Remove two screws. * Discard the removed screws.

2 Remove the Barrier Assy. * Discard the removed Barrier Assy.

* After removing the Barrier Assy, if the “G1 Dust-Proof Ring” was removed, it must be returned to the home position.

In returning the ring, adjust the location of a projection to the lens direction. This is an important part to prevent the dust and light from coming in.

* After removing the Barrier Assy, take extreme care not to drop dust or foreign substances in the lens barrel.

2-2-3. INSTALL NEW BARRIER ASSY

1 Install new Barrier Assy.

2 Tighten two screws.

* Tightening torque = 0.5 kgf

DSC-W50_L2

2-7

2-2-4. ADHERE THE ORNAMENTAL RING A

Apply an adhesive tape to two recesses on the top surface of the Barrier Assy.

Meeting a “notch” of the Ornamental Ring A with a “projection” of the group-1 frame, push the Ornamental Ring A into the group-1 frame. * The projection of the spring for preventing static electricity must be tilted.

Put the 60g weight on the Ornamental Ring A so that the Ornamental Ring A does not float up until the adhesive hardens. Note: Be careful not to give a shock. * After the weight was put, no gap must be present in full circumference between Ornamental Ring A and group-1 frame.

A gap, if present, causes the crackle sound NG.

* The weight must push in the Ornamental Ring A only.

If the weight is put on the mold part of the Barrier Assy, the Ornamental Ring A will float up.

Do not put the weight on a black mold part.

Adhesive tape

Completion after 30 minutes.
