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)

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)

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.

NOTE  OF  REPLACING  THE  CN3005, IC3008 AND  
IC3700  ON  THE  D-VIDEO  NW  BOARD
CN3005, IC3008 and IC3700 on the D-VIDEO NW board cannot 
exchange with single. When these parts are damaged, exchange the 
complete mounted board.

NOTE  OF  REPLACING  THE  CN2513  AND  IC2811  ON  
THE  DIGITAL  BOARD
CN2513 and IC2811 on the DIGITAL board cannot exchange with 
single. When these parts are damaged, exchange the complete 
mounted board.

NOTE  OF  REPLACING  THE  IC5001  ON  THE  DSP  BOARD
IC5001 on the DSP board cannot exchange with single. When this 
part is damaged, exchange the complete mounted board.

CAPACITOR  ELECTRICAL  DISCHARGE  PROCESSING
When checking the board, for the electric shock prevention, con-
nect the resistors to both ends of respective capacitors (C930 and 
C931 on the MAIN board) to discharge the capacitors (C930 and 
C931 on the MAIN board).

Before using the receiver for the first time, 
initialize the receiver by performing the 
following procedure. This procedure can also 
be used to revert back to the factory default 
settings. 
Be sure to use the buttons on the receiver to 
perform this operation.

Press ?/1 to turn off the 
receiver.

Hold down ?/1 for 5 seconds.

The “CLEARING” appears on the 
display panel for a while, then changes to 
“CLEARED !”.
Changes or adjustments made to the 
settings are now reset to the defaults.

If there is a malfunction, a message appears on 
the display panel. You can check the condition 
of the system by the message. If any problem 
persists, consult your nearest Sony dealer. 

Irregular current is output to the speakers, or 
the receiver is covered and ventilation holes 
are blocked. The receiver will automatically 
turn off after a few seconds. Remove the 
object covering the upper panel of the 
receiver, check the speaker connection and 
turn on the power again.

An over current from the 

 (USB) port was 

detected. The receiver will automatically 
turn off after a few seconds. Check the 

iPod/iPhone or USB device, then unplug it 
and turn on the power again.

alligator clip
Note: Connect altogether the metal part
 

on the boards connected with the

 

chassis using the alligator clip.

NOTE  OF  OPERATION  CHECKS
When checking the operation of each board, be sure to connect the GND of each board to rear panel with alligator clips.
