WARNING!!

WHEN SERVICING, DO NOT APPROACH THE LASER

EXIT WITH THE EYE TOO CLOSELY. IN CASE IT IS

NECESSARY TO CONFIRM LASER BEAM EMISSION,

BE SURE TO OBSERVE FROM A DISTANCE OF MORE

THAN 25 cm FROM THE SURFACE OF THE

OBJECTIVE LENS ON THE OPTICAL PICK-UP BLOCK.

CAUTION

Use of controls or adjustments or performance of procedures

other than those specified herein may result in hazardous

radiation exposure.

SAFETY-RELATED COMPONENT WARNING!!

LEAKAGETEST

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. Measuringthevoltagedropacrossaresistor by means of aVOM

or battery-operated AC voltmeter. The “limit” indication is

0.75V, soanalogmetersmusthaveanaccuratelow-voltage scale.

The Simpson 250 and Sanwa SH-63Trd are examples of a

passiveVOM that is suitable. Nearly all battery operated digital

multimeters that have a 2VAC range are suitable. (See Fig. A)

1. Check the area of your repair for unsoldered or poorly-soldered

connections. Check the entire board surface for solder splashes

and bridges.

2. Check the interboard wiring to ensure that no wires are

“pinched” or contact high-wattage resistors.

3. Lookfor unauthorized replacement parts,particularlytransistors,

that were installed during a previous repair. Point them out to

the customer and recommend their replacement.

4. Look for parts which, though functioning, show obvious signs

ofdeterioration. Pointthemouttothecustomerandrecommend

their replacement.

5. Check the line cord for cracks and abrasion. Recommend the

replacement of any such line cord to the customer.

6. Check the B+ voltage to see it is at the values specified.

7. Check the antenna terminals, metal trim, “metallized” knobs,

screws,and all other exposedmetal parts forACleakage. Check

leakage as described below.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following

safety checks before releasing the set to the customer:

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.

PRECAUTIONS

1 SAFETY PRECAUTIONS

1) Before returning an instrument to the customer, always make a

safety check of the entire instrument, including, but not limited

to, the following items:

(1) Be sure that no built-in protective devices are defective or have

been defeated during servicing.

(1)Protective shields are provided to protect both the technician

and the customer. Correctly replace all missing protective

shields, including any removed for servicing convenience.

(2)When reinstalling the chassis and/or other assembly in the

cabinet, be sure to put back in place all protective devices,

including, but not limited to, nonmetallic control knobs,

insulating fish papers, adjustment and compartment covers/

shields,and isolation resistor/capacitor networks. Donot operate

this instrument or permit it to be operated without all protective

devices correctly installed and functioning.

(2) Be sure that there are no cabinet openings through which adults

or children might be able to insert their fingers and contact a

hazardous voltage. Such openings include, but are not limited

to, excessively wide cabinet ventilation slots, and an improperly

fitted and/or incorrectly secured cabinet back cover.

(3) Leakage Current Hot Check-With the instrument completely

reassembled, plug the AC line cord directly into a 120V AC

outlet. (Do not use an isolation transformer during this test.)

Use a leakage current tester or a metering system that complies

with American National Standards institute (ANSI) C101.1

Leakage Current forAppliances and Underwriters Laboratories

(UL) 1270 (40.7). With the instrument’s AC switch first in the

ONposition and then intheOFF position, measure from aknown

earth ground (metal water pipe, conduit, etc.) to all exposed

metal parts of the instrument (antennas, handle brackets, metal

cabinets, screwheads, metallic overlays, control shafts, etc.),

especially any exposed metal parts that offer an electrical return

path to the chassis.

Any current measured must not exceed 0.5mA. Reverse the

instrument power cord plug in the outlet and repeat the test. See

Fig. 1.

Anymeasurements not withinthe limits specifiedherein indicate

apotential shock hazard that must be eliminated before returning

the instrument to the customer.

(4) Insulation Resistance Test Cold Check-(1) Unplug the power

supply cord and connect a jumper wire between the two prongs

of the plug. (2) Turn on the power switch of the instrument. (3)

Measurethe resistance with an ohmmeter between the jumpered

AC plugand all exposedmetallic cabinet parts on the instrument,

such as screwheads, antenna, control shafts, handle brackets,

etc. When an exposed metallic part has a return path to the

chassis,the reading should be between 1 and 5.2 megohm.When

there is no return path to the chassis, the readingmust be infinite.

If the reading is not within the limits specified, there is the

possibilityof a shock hazard, and the instrument must be repared

and rechecked before it is returned to the customer. See Fig. 2.

3) DesignAlterationWarning-Do not alter or add to the mechanical

or electrical design of this instrument. Design alterations and

additions, including but not limited to, circuit modifications and

the addition of items such as auxiliary audio output connections,

mightalter the safety characteristics of this instrument and create

a hazard to the user. Any design alterations or additions will

make you, the servicer, responsible for personal injury or

property damage resulting therefrom.

4) Observe original lead dress. Take extra care to assure correct

lead dress in the following areas:

(1) near sharp edges, (2) near thermally hot parts (be sure that

leads and components do not touch thermally hot parts), (3) the

AC supply, (4) high voltage, and (5) antenna wiring. Always

inspect in all areas for pinched, out-of-place, or frayed wiring,

Do not change spacing between a component and the printed-

circuit board. Check the AC power cord for damage.

5) Components,parts,and/or wiring that appear to haveoverheated

or that are otherwise damaged should be replaced with

components, parts and/ or wiring that meet original

specifications.

Additionally, determine the cause of overheating and/or damage

and, if necessary, take corrective action to remove any potential

safety hazard.

6) Product Safety Notice-Some electrical and mechanical parts

have special safety-related characteristics which are often not

evident from visual inspection, nor can the protection they give

necessarilybe obtained by replacingthem with components rated

for higher voltage, wattage, etc. Parts that have special safety

characteristics are identified by shading, an ( ) or a ( ) on

schematics and parts lists. Use of a substitute replacement that

does not have the same safety characteristics as the

recommended replacement part might create shock, fire and/or

other hazards. Product safety is under review continuously and

new instructions are issued whenever appropriate.

2 SERVICING PRECAUTIONS

CAUTION: Before servicing units covered by this service manual

and its supplements, read and follow the Safety Precautions section

of this manual.

Note: If unforseen circumstances create conflict between the

following servicing precautions and any of the safety precautions,

always follow the safety precautions. Remember: Safety First.

2-1 General Servicing Precautions

(1) a. Always unplug the instrument’sAC power cord from theAC

power source before (1) re-moving or reinstalling any

component, circuit board, module or any other instrument

assembly, (2) disconnecting any instrument electrical plug or

other electrical connection, (3) connecting a test substitute in

parallel with an electrolytic capacitor in the instrument.

b. Do not defeat any plug/socket B+ voltage interlocks with

which instruments covered by this service manual might be

equipped.

c. Do not apply AC power to this instrument and/or any of its

electrical assemblies unless all solid-state device heat sinks

are correctly installed.

d. Always connect a test instrument’s ground lead to the

instrument chassis ground before connecting the test

instrument positive lead. Always remove the test instrument

ground lead last.

Note: Refer to the Safety Precautions section ground lead last.

(2) The service precautions are indicated or printed on the cabinet,

chassis or components. When servicing, follow the printed or

indicated service precautions and service materials.

(3)The components used in the unit have a specified flame

resistance and dielectric strength.

When replacing components, use components which have the

same ratings. Components identified by shading, by ( ) or by

() in the circuit diagram are important for safety or for the

characteristics of the unit. Always replace them with the exact

replacement components.

(4) An insulation tube or tape is sometimes used and some

components are raised above the printed wiring board for safety.

The internal wiring is sometimes clamped to prevent contact

with heating components. Install such elements as they were.

(5) After servicing, always check that the removed screws,

components, and wiring have been installed correctly and that

the portion around the serviced part has not been damaged and

so on. Further, check the insulation between the blades of the

attachment plug and accessible conductive parts.

2-2 Insulation Checking Procedure

Disconnect the attachment plug from the AC outlet and turn the

power ON. Connect the insulation resistance meter (500V) to the

blades of the attachment plug. The insulation resistance between

each blade of the attachment plug and accessible conductive parts

(see note) should be more than 1 Megohm.

Note: Accessible conductive parts include metal panels, input

terminals, earphone jacks, etc.

3 ESD PRECAUTIONS

Electrostatically Sensitive Devices (ESD)

Some semiconductor (solid state) devices can be damaged easily

by static electricity.

Such components commonly are called Electrostatically Sensitive

Devices (ESD). Examples of typical ESD devices are integrated

circuits and some field-effect transistors and semiconductor chip

components.Thefollowing techniquesshould be used to help reduce

the incidence of component damage caused by static electricity.

(1) Immediately before handling any semiconductor component or

semiconductor-equipped assembly, drain off any electrostatic

charge on your body by touching a known earth ground.

Alternatively, obtain and wear a commercially available

discharging wrist strap device, which should be removed for

potential shock reasons prior to applying power to the unit under

test.

(2) After removing an electrical assembly equipped with ESD

devices, place the assembly on a conductive surface such as

aluminum foil, to prevent electrostatic charge buildup or

exposure of the assembly.

(3) Use only a grounded-tip soldering iron to solder or unsolder

ESD devices.

(4) Use only an anti-static solder removal devices. Some solder

removal devices not classified as “anti-static” can generate

electrical charges sufficient to damage ESD devices.

(5) Do not use freon-propelled chemicals. These can generate

electrical charges sufficient to damage ESD devices.

(6) Do not remove a replacement ESD device from its protective

package until immediately before your are ready to install it.

(Most replacement ESD devices are packaged with leads

electrically shorted together by conductive foam, aluminum foil

or comparable conductive materials).

(7) Immediately before removing the protective materials from the

leadsofareplacement ESD device, touch the protective material

to the chassis or circuit assembly into which the device will be

installed.

CAUTION: Be sure no power is applied to the chassis or circuit,

and observe all other safety precautions.

(8) Minimize bodily motions when handling unpackaged

replacement ESD devices. (Otherwise harmless motion such as

the brushing together of your clothes fabric or the lifting of

your foot from a carpeted floor can generate static electricity

sufficient to damage an ESD device).

4 HANDLING THE OPTICAL PICK-UP

The laser diode in the optical pick up may suffer electrostatic

breakdown because of potential static electricity from clothing and

your body.

The following method is recommended.

(1) Place a conductive sheet on the work bench (The black sheet

used for wrapping repair parts.)

(2) Place the set on the conductive sheet so that the chassis is

grounded to the sheet.

(3) Place your hands on the conductive sheet (This gives them the

same ground as the sheet.)

(4) Remove the optical pick up block

(5) Perform work on top of the conductive sheet. Be careful not to

let your clothes or any other static sources to touch the unit.

◆Be sure to put on a wrist strap grounded to the sheet.

◆Be sure to lay a conductive sheet made of copper etc. Which is

grounded to the table.

Fig.3

(6) Short the short terminal on the PCB, which is inside the Pick-

UpASS’Y, before replacing the Pick-Up. (The short terminal is

shorted when the Pick-Up Ass’y is being lifted or moved.)

(7) After replacing the Pick-up, open the short terminal on the PCB.
