Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be
damaged by heat.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety check before releasing the set to the customer:
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 before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs, screws,
and all other exposed metal parts for AC leakage.
Check leakage as described below.
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.
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” indication
is 0.75 V, so analog meters must have an accurate low-voltage
scale. The Simpson 250 and Sanwa SH-63Trd are examples
of a passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2 V AC range are suitable. (See
Fig. A)

SERVICING NOTES
BEGIN IT BEFORE THE REPAIR
When the SA-WSIS50 is checked, connect to HCD-IS50 (for
DVD receiver of DAV-IS50). Be sure in advance the HCD-IS50
is prepared.
When the SA-WSIS50 is checked, connect to HCD-IS50 (for
DVD receiver of DAV-IS50). Be sure in advance the HCD-IS50
is prepared.
NOTE OF WHEN OUTPUT IS CONFIRMED (SS-IS15)
To connect with SA-WSIS50 and to use it, SS-IS15 is designed.
Therefore, when it connects with an usual amplifi er and the audio
signal of an excessive low-frequency (800 Hz or less) is input, there
is a possibility that the speaker breaks.
When you confi rm the output with large audio signal input, connect
SA-WSIS50 with SS-IS15.

NOTE OF REPLACING THE EEPROM (IC1009) ON DSP
BOARD
When you replace EEPROM (IC1009), connect HCD-IS50 and
SA-WSIS50 and execute “Cold reset” (See page 24 of HCD-IS50
Service Manual) and “Execute Initialize Setup Data” (See page 27
of HCD-IS50 Service Manual).

:
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 fl ow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.
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.
