TABLE OF CONTENTS
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. Acommercial 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-operatedAC 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 VAC 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 flow)
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 CONTROL 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.
