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.

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

SECTION 1

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 (C003)]

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-P7 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.
