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 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)

SECTION  1
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.
NOTE  OF  REPLACING  THE  IC2022  ON  THE  DIGITAL  
BOARD
IC2022 on the DIGITAL board cannot exchange with single. 
When this part on the DIGITAL board is damaged, exchange the 
entire mounted board.
NOTE  OF  REPLACING  THE  IC3201,  IC3202,  IC3500  
AND  IC3501  ON  THE  D-VIDEO  BOARD
IC3201, IC3202, IC3500 and IC3501 on the D-VIDEO board 
cannot exchange with single. When these parts on the D-VIDEO 
board are damaged, exchange the entire mounted board.

If there is a malfunction, the display shows a 
message. You can check the condition of the 
system by the message. See the following table 
to solve the problem. If any problem persists, 
consult your nearest Sony dealer. 
If an error message appears while you perform
Auto Calibration, see “When error codes 
appear” to solve the problem.
PROTECTOR
Irregular current is output to the speakers, or 
the upper panel of the receiver is covered 
with something. The receiver will 
automatically turn off after a few seconds. 
Check the speaker connection and turn on 
the power again.
Clearing the receiver’s memory may remedy 
the problem. However, note that all 
memorized settings will be reset to their initial 
settings and you will have to readjust all 
settings on the receiver.
