SAFETY-RELATED COMPONET WARNING!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE

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.

SAFETY CHECK-OUT

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.

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)

TABLE OF CONTENTS

SECTION 1

SERVICING NOTES

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead­free 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 viscou-s (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 IC3511 AND IC3513 ON
THE HDMI BOARD

IC3511 and IC3513 on the HDMI board cannot exchange with sin­gle. When IC3511 and IC3513 on the HDMI board are damaged,
exchange the entire mounted board.

NOTE OF REPLACING THE IC1131 ON THE DIGITAL
AB BOARD

IC1131 on the DIGITAL AB board cannot exchange with single.
When IC1131 on the DIGITAL AB board is damaged, exchange
the entire mounted board.

signal

generator

set

Procedure:

1. Turn on the set.

2. Input the following signal from signal generator to FM antenna
input directly.

Carrier frequency: A = 87.5 MHz, B = 98 MHz, C = 108 MHz

Deviation : 75 kHz
Modulation : 1 kHz
ANT input : 1 kHz

Note: Use 75 ohm coaxial cable to connect signal generator and the set.

You cannot use video cable for checking.

Use signal generator whose output impedance is 75 ohm.

3. Set to FM tuner function and scan the input FM signal with
automatic scanning.

4. Confi rm that input frequency of A, B and C are detected and
automatic scanning stops.

When the station signal is received in good condition, automatic

For Schematic Diagrams.

Note:

• All capacitors are in μF unless otherwise noted. (p: pF)
50 WV or less are not indicated except for electrolytics

and tantalums.

• All resistors are in Ω and 1/4 W or less unless otherwise
specifi ed.

• f : internal component.

• 2 : nonfl ammable resistor.

• 5 : fl usible resistor.

• C : panel designation.

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)

• A : B+ Line.

• B : B– Line.

• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.

no mark : TUNER

• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.

• Waveforms are taken with a oscilloscope.

Voltage variations may be noted due to normal production

tolerances.

• Circled numbers refer to waveforms.

• Signal path.

J : AUDIO (DIGITAL)
F : AUDIO (ANALOG)
f : TUNER
E : VIDEO

For Printed Wiring Boards.

Note:

• X : Parts extracted from the component side.

• Y : Parts extracted from the conductor side.

• f : Internal component.

• : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)

• Indication of transistor.

Caution:

Parts face side:

Parts on the parts face side seen from
the pattern face are indicated.
Parts on the pattern face side seen from
the parts face are indicated.

• Circuit Boards Location

Caution:

(Component Side)

Parts on the pattern face side seen from
the pattern face are indicated.
Parts on the parts face side seen from
the parts face are indicated.

Note: The components identifi ed by mark 0 or dotted

line with mark 0 are critical for safety.

Replace only with part number specifi ed.
