NOTES  ON  CHIP  COMPONENT  REPLACEMENT
• 
Never reuse a disconnected chip component.
• 
Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
SAFETY  CHECK-OUT
After correcting the original service problem, perform the follow-
ing 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.
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
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 fl ow) 
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.
ADVANCE  PREPARATION  WHEN  CONFIRMING  OP-
ERATION
When the operation of the TA-SA200WR is confi rmed, it is nec-
essary to communicate the set of main unit with S-AIR and TA-
SA200WR and confi rm.
Confi rm the main unit with S-AIR, TA-SA200WR and EZW-RT10 
etc. are prepared beforehand when you repair.
DIRECTION  OF  EZW-RT10/RT10A  INSTALLATION
When EZW-RT10/RT10A is install with the AMP board detached 
of the set, the label of EZW-RT10/RT10A is the under and install.

Checking the 
transmission status
You can check the status of sound 
transmission between the S-AIR main unit 
and surround amplifier by checking the 
S-AIR/STANDBY indicator on the 
surround amplifier.
S-AIR/

Status
Turns green.
The system is turned on, 
wireless transmission is 
activated and surround 
signals are transmitting.

s Check that the AC power cord (mains lead) of 
the surround amplifier is connected securely.
s Turn the surround amplifier on by pressing 
"/1 on the surround amplifier.
– Flashes orange.
s Check that the wireless transceiver is inserted 
into the surround amplifier correctly.
– Flashes green quickly.
s Change the S-AIR ID settings of the S-AIR 
main unit and surround amplifier.
cWhen you use this system with surround 
speakers:
s Set the SURROUND SELECTOR switch of 
the surround amplifier to SURROUND.
cWhen you use this system with surround 
back speakers:
s Set [Surround Back] in [Speaker Settings] of 
the S-AIR main unit to [Yes]. For details, 
refer to the operating instructions of the 
S-AIR main unit.
– Flashes red.
s Press 
"/1 to turn off the surround amplifier, 
and check the following items.
1 Are the + and – speaker cords short-
circuited?
2 Is anything blocking the ventilation 
holes of the surround amplifier?
After checking the above items and fixing 
any problems, turn on the surround amplifier. 
If the cause of the problem cannot be found 
Troubleshooting
even after checking all the above items, 
consult your nearest Sony dealer.
– Flashes green slowly or turns red.
s Confirm the S-AIR IDs of the S-AIR main 
unit and surround amplifier.
s Confirm the pairing setting.
s Sound transmission is poor. Move the 
surround amplifier so that the S-AIR/
STANDBY indicator turns green.
s Move the system away from other wireless 
devices.
s Avoid using any other wireless devices.
– Turns green.
s Check the speaker connections and settings.
s Depending on the source or the settings of the 
S-AIR main unit, the effect of the speakers 
may be less noticeable.
