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)

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  IC5001  ON  THE  DSP  
BOARD
IC5001 on the DSP board cannot exchange with single. When this 
part is damaged, exchange the complete mounted board.
NOTE  OF  REPLACING  THE  IC3601  ON  THE  D-VIDEO  
BOARD
Replacement of IC3601 on the D-VIDEO board used in this unit 
requires a special tool.
NOTE  OF  REPLACING  THE  IC3511  AND  IC3513  ON  
THE  D-VIDEO  BOARD
IC3511 and IC3513 on the D-VIDEO board cannot exchange with 
single. When these parts are damaged, exchange the complete 
mounted board.
NOTE  OF  REPLACING  THE  IC101,  IC304,  IC501  AND  
IC2503  ON  THE  NETWORK  BOARD
IC101, IC304, IC501 and IC2503 on the NETWORK board cannot 
exchange with single. When these parts are damaged, exchange the 
complete mounted board.
NOTE  OF  REPLACING  THE  IC106,  IC107,  IC206  AND  
IC207  ON  THE  NETWORK BOARD
Replacement of IC106, IC107, IC206 and IC207 on the NET-
WORK board used in this unit requires a special tool.

UPDATE  OF  SOFTWARE  OF  IC3601  ON  THE  D-
VIDEO  BOARD,  IC2501  ON  THE  CONTROL  BOARD, 
IC763  ON  THE  DISPLAY  BOARD
Perform operation of the following when the update of software 
of the IC3601 on the D-VIDEO board, IC2501 on the CONTROL 
board and IC763 on the DISPLAY board are necessary.
Connect:
for PC
HAT Board
J861
– Rear side –
Procedure:
1.  Connect the RS232C terminal on rear side of this unit (J861 on 
the HAT board) and PC by using the RS-232C cable.
2.  Press the [\/1] button to turn on the main power.
3.  The update is executed by using application on PC.
4.  When the update ends, turn off the main power.
5.  Remove the RS-232C cable from the RS232C terminal on rear 
side of this unit (J861 on the HAT board) and PC.
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.

While holding down the TONE 
MODE and 2CH/A.DIRECT, 
press 
?/1 to turn on the 
receiver.
3
Release the TONE MODE and 
2CH/A.DIRECT after a few 
seconds.
The “CLEARING” appears on the 
display window for a while, then changes 
to “CLEARED !”
Changes or adjustments made to the 
settings are now reset to the defaults.

cleared completely. Do not turn the receiver off until 
“CLEARED !” appears on the display.
You can check the status of the receiver by the 
message. See the following table to solve the 
problem. If any problem persists, consult your

are blocked. The receiver will automatically 
turn off after a few seconds. Remove the 
object covering the upper panel of the 
receiver and turn on the power again.
SPEAKER SHORTED
Irregular current is output to the speakers 
due to a short circuit on the speaker 
terminals. The receiver will automatically 
turn off after a few seconds. If the protective 
device on the receiver is activated due to a 
short-circuit problem, turn off the receiver. 
Check the connection of the speakers and 
turn on the power again.
FAN STOPPED
Check that the ventilation hole on the top of 
the receiver are not blocked. Place the 
receiver in a location with adequate 
ventilation to prevent heat build-up in the 
receiver.
