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)

Note: Refer to “NOTE WHEN THE DC-DC BOARD IS RE-

TYPE A/B.

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  IC3601  ON  THE  
D-VIDEO  BOARD  
Replacement of IC3601 on the D-VIDEO board used in this set 
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 IC3511 and IC3513 on the D-VIDEO board are dam-
aged, exchange the entire mounted board.

NOTE  OF  REPLACING  THE  IC5002  AND  IC5202  ON  
THE  DSP  BOARD
IC5002 and IC5202 on the DSP board cannot exchange with sin-
gle. When IC5002 and IC5202 on the DSP board are damaged, 
exchange the entire mounted board.

UPDATE  OF  SOFTWARE  OF  IC2003  ON  THE  CON-
TROL  BOARD,  IC3610  ON  THE  D-VIDEO  BOARD  AND  
IC5208  ON  THE  DSP  BOARD
Perform operation of the following when the update of software 
of the IC2003 on the CONTROL board, IC3610 on the D-VIDEO 
board and IC5208 on the DSP board is necessary.

Procedure:
1.  Connect J1499 on the MAIN board and PC by using the RS-

232C cable.

2.  Turn on the main power.
3.  The update is executed by using PC.
4.  When the update ends, turn off the main power.
5.  Remove the RS-232C cable from the J1499 on the MAIN 

board and PC.

ERROR  MESSAGES
If there is a malfunction, the display shows a code of two numbers and a message. You can check the condition of the system by the message. 
Refer to the following table 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. Cheack the speakers connection and turn 
on the power again.

NOTE  WHEN  THE  DC-DC  BOARD  IS  REPAIRED
