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” indica-
tion 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)

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.

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.

Special Component Notice
The components identifi ed by mark 

9 contain confi dential infor-

mation.
Strictly follow the instructions whenever the components are re-
paired and/or replaced.

Notice pour composants spéciaux
Les composants identifi és par la marque 

9 contiennent des infor-

mations confi dentielles.
Suivre scrupuleusement les instructions chaque fois qu’un com-
posant est remplacé et / ou réparé.

NOTE OF REPLACING THE IC3500 AND IC3501 ON THE 
HDMI PC BOARD
IC3500 and IC3501 on the HDMI PC board cannot exchange with 
single. When these parts on the HDMI PC board are damaged,
exchange the entire mounted board.
