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.

ATTENTION AU COMPOSANT AYANT RAPPORT

À LA SÉCURITÉ!

LES COMPOSANTS IDENTIFÉS PAR UNE MARQUE 0 SUR LES

DIAGRAMMES SCHÉMATIQUES 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.

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.

Unleaded solder

Boards requiring use of unleaded solder are printed with the lead-

free 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.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following

safety checks before releasing the set to the customer.

CAUTION

Danger of explosion if battery is incorrectly replaced.

Replace only with the same or equivalent type.

DISCHARGING OF THE ST-163 BOARD’S CHARGING CAPACITOR (C901)

The charging capacitor (C901) of the ST-163 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

As the discharging location is in depths, the short jig may touch

to the opening of frame.

Expose the tip of resistor of 1kΩ /1 W (1-215-869-11) by 1mm

and insulate the rest of it with insulation tape.

1 kΩ/1 W

Wrap insulating tape.

to about 1mm

Note: High-voltage cautions

Discharging the Capacitor

Short-circuit between the two points

with the short jig about 10 seconds.

To avoid the spark with the metal plate,

wrap the short jig with the insulation tape.
