Earth Ground
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground
and from all exposed metal parts to any exposed metal part having
a return to chassis, must not exceed 0.5 mA (500 microamperes).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers' instructions to use these
instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indica-
tion is 0.75V, so analog meters must have an accurate low-
voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex-
amples of a passive VOM that is suitable. Nearly all battery
operated digital multimeters that have a 2V AC range are suit-
able. (See Fig. A)
1. Check the area of your repair for unsoldered or poorly-sol-
dered 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 transis-
tors, that were installed during a previous repair. Point them
out to the customer and recommend their replacement.
4. Look for parts which, though functioning, show obvious signs
of deterioration. Point them out to the customer and recom-
mend their replacement.
5. Check the line cord for cracks and abrasion. Recommend the
replacement of any such line cord to the customer.
6. Check the B+ voltage to see it is at the values specified.
7. Check the antenna terminals, metal trim, “metallized” knobs,
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:

Precautions
On safety
Should any solid object or liquid fall into the cabinet,
unplug the speaker system and have it checked by
qualified personnel before operating it any further.
On power sources
•AC power cord must be changed only at the qualified
service shop.
•Before operating the speakers, check that the operating
voltage is identical with your local power supply. The
operating voltage is indicated on the nameplate on the
rear of the speakers.
•The unit is not disconnected from the AC power
source as long as it is connected to the wall outlet, even
if the unit itself has been turned off.
•If you are not going to use the speakers for a long time,
be sure to disconnect the speakers from the wall outlet.
To disconnect the AC power cord, grasp the plug itself;
never pull the cord.
On placement
• Do not install the appliance in a confined space, such
as a bookcase or built-in cabinet.
• Do not place the speakers near heat sources, or in a
place subject to direct sunlight, excessive dust or
mechanical shock.
• Good ventilation is essential to prevent internal heat
buildup. Place the speakers in a location with adequate
air circulation, and in a way that does not block the
rear ventilation holes.
On operation
•When turning on or off the subwoofer or other
equipment, lower the volume of the subwoofer to
minimum.
•To avoid damaging the subwoofer:
– Be careful in setting the volume control of the
subwoofer to avoid an excessive input power.
– Do not open the enclosure or remold speaker units
and networks.
– The grill net is not removable. Do not remove it.
On the speaker system
Although this speaker system is magnetically shielded,
there may be cases where the picture on some TV sets
becomes magnetically distorted. In such a case, turn off
the power of the TV set once, and after 15 to 30 minutes
turn it on again.
If there seems to be no improvement, locate the
speaker system further away from the TV set. Also, be
sure not to place objects in which magnets are attached
or used near the speaker system, such as audio racks, TV
stands, and toys. These may cause magnetic distortion to
the picture due to their interaction with the system.
On cleaning
Clean the cabinet, panel and controls with a soft cloth
slightly moistened with a mild detergent solution. Do
not use any type of abrasive pad, scouring powder or
solvent such as alcohol or benzine.
If you have any question or problem concerning your
speaker system, please consult your nearest Sony dealer.

satellite speakers, use the supplied speaker
stands. (fig. B)
Speaker stands WS-FV10A, WS-TV10A, and WS-
WV10A are also available on option.
You can install the satellite speakers on the wall
using commercially available screws. (fig. C)
You need to determine the appropriate hanging
screws and/or other necessary hardware needed
to securely and safely fasten the speakers to the
wall. Please be sure you have selected fasteners
or screws that will fit in the hanging holes on the
rear of the speaker.
Placement of the screws should be at the same
height and should be 2 3/8 in. (59 mm) apart. The
screws or other fasteners should protrude by
3/16 in. to 7/32 in. (4 to 5 mm). You may also
mark placement of the screws or fasteners by use
of something like a template.
Hang the speakers on the screws and push the
speakers so that they fit against the wall.

PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed
in each block.)
For printed wiring boards:
•X: indicates a lead wire mounted on the component
side.
•x: indicates a lead wire mounted on the printed side.
•b: Pattern from the side which enables seeing.
(The other layers’ patterns are not indicated.)
For schematic diagram:
• Caution when replacing chip parts.
New parts must be attached after removal of chip.
Be careful not to heat the minus side of tantalum capacitor,
because it is damaged by the heat.
• All resistors are in ohms, 1/4 W (Chip resistors : 1/10 W) un-
less otherwise specified.
kΩ : 1000Ω, MΩ : 1000kΩ.
• All capacitors are in µF unless otherwise noted. pF : µµF
50V or less are not indicated except for electrolytics and
tantalums.
• All variable and adjustable resistors have characteristic curve
B, unless otherwise noted.
•2: nonflammable resistor.
•5: fusible resistor.
•C: panel designation.
•f: internal component.
•C: adjustment for repair.
•U: B+ Line.
•V: B– Line.
• Circled numbers refer to waveforms.
• Voltages are dc between measurement point.
• Voltage and waveforms are dc with respect to ground under
no-signal conditions.
• Readings are taken with a digital multimeter (DC 10MΩ).
• Voltage variations may be noted due to normal production
tolerances.
When indicating parts by reference
number, please include the board
name.
Note:
The components identi-
fied by mark 0 or dotted
line with mark 0 are criti-
cal for safety.
Replace only with part
number specified.
Note:
Les composants identifiés par
une marque 0 sont critiques
pour la sécurité.
Ne les remplacer que par une
pièce portant le numéro
spécifié.
