After correcting the original service problem, perform the following 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.

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 chas-

sis, 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 Simp-

son 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)

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.

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.

The components identifi ed by mark 9 contain confi dential

information.

Strictly follow the instructions whenever the components are

repaired and/or replaced.
Notice pour composants spéciaux

Les composants identifi és par la marque 9 contiennent des

informations confi dentielles.

Suivre scrupuleusement les instructions chaque fois qu’un com-

posant est remplacé et / ou réparé.
NOTE OF REPLACING THE IC4100 ON THE USB BOARD

entire mounted board.
NOTE OF REPLACING THE IC3500 AND IC3501 ON THE 

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.

MICOM (IC2105) ON DIGITAL BOARD SERVICE POSITION
•  In checking the MICOM (IC2105) on the DIGITAL board, 

prepare a set of extension jigs (A-1825-238-A) which consists 
of two extension cables.
