•  SA-WCT500 is the amplifi er, HDMI, tuner, video 
and active subwoofer section in HT-CT500.
•  SS-CT500 is the speaker system in HT-CT500.
• When the operation of the subwoofer (SA-
WCT500) or satellite speaker (SS-CT500) is 
confi rmed, it is necessary to connect both these 
set.
 Confi rm the subwoofer (SA-WCT500) and sat-
ellite speaker (SS-CT500) are prepared before-
hand when you repair.

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

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.
ADVANCE  PREPARATION  WHEN  CONFIRMING  OP-
ERATION
When the operation of the subwoofer (SA-WCT500) or satellite 
speaker (SS-CT500) is confi rmed, it is necessary to connect both 
these set.
Confi rm the subwoofer (SA-WCT500) and satellite speaker (SS-
CT500) are prepared beforehand when you repair.
NOTE  OF  CONFIRMING  THE  BOARDS (SA-WCT500)
Protecting is generated when energizing with the heat sink de-
tached. Fix the heat sink to the MAIN board by using the screw 
and the nut without fail when you confi rm the board.
CONFIRMING  THE  POWER  BOARD (SA-WCT500)
The POWER board can be confi rmed by removing the bottom 
plate of the active subwoofer.
NOTE  THE  IC3506  AND  IC3508  ON  THE  D-VIDEO  
BOARD  REPLACING (SA-WCT500)
IC3506 and IC3508 on the D-VIDEO board cannot exchange with 
single. When these parts are damaged, exchange the entire mount-
ed board.
