1. Precautions

1-1 Safety Precautions

1. Be sure that all of the built-in protective

devices are replaced. Restore any missing

protective shields.

2. When reinstalling the chassis and its

assemblies, be sure to restore all protective

devices, including: nonmetallic control knobs

and compartment covers.

3. Make sure that there are no cabinet openings

through which people—particularly

children—might insert fingers and contact

dangerous voltages. Such openings include

the spacing between the picture tube and the

cabinet mask, excessively wide cabinet

ventilation slots, and improperly fitted back

covers.

If the measured resistance is less than 1.0

megohm or greater than 5.2 megohms, an

abnormality exists that must be corrected

before the unit is returned to the customer.

4. Leakage Current Hot Check (Figure 1-1):

Warning: 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 (ANIS C101.1, Leakage Current for

Appliances), and Underwriters Laboratories

(UL Publication UL1410, 59.7).

5. With the unit completely reassembled, plug

the AC line cord directly into the power

outlet. With the unit’s AC switch first in the

ON position and then OFF, measure the

current between a known earth ground (metal

water pipe, conduit, etc.) and all exposed

metal parts, including: antennas, handle

brackets, metal cabinets, screwheads and

control shafts. The current measured should

not exceed 0.5 milliamp. Reverse the power-

plug prongs in the AC outlet and repeat the

test.

Fig. 1-1 AC Leakage Test

6. Antenna Cold Check:

With the unit’s AC plug disconnected from the

AC source, connect an electrical jumper across

the two AC prongs. Connect one lead of the

ohmmeter to an AC prong. Connect the other

lead to the coaxial connector.

7. X-ray Limits:

The picture tube is especially designed to pro-

hibit X-ray emissions. To ensure continued

X-ray protection, replace the picture tube only

with one that is the same type as the original.

Carefully reinstall the picture tube shields and

mounting hardware; these also provide X-ray

protection.

8. High Voltage Limits:

High voltage must be measured each time ser-

vicing is done on the B+, horizontal deflection

or high voltage circuits. Correct operation of

the X-ray protection circuits must be

reconfirmed whenever they are serviced.

(X-ray protection circuits also may be called

“horizontal disable” or “hold-down”.)

Heed the high voltage limits. These include

the X–ray Protection Specifications Label, and

the Product Safety and X-ray Warning Note on

the service data schematic.

1-1 Safety Precautions (Continued)

9. High voltage is maintained within specified

limits by close-tolerance, safety-related

components and adjustments. If the high

voltage exceeds the specified limits, check

each of the special components.

10. Design Alteration Warning:

Never alter or add to the mechanical or

electrical design of this unit. Example: Do not

add auxiliary audio or video connectors. Such

alterations might create a safety hazard. Also,

any design changes or additions will void the

manufacturer’s warranty.

11. Hot Chassis Warning:

Some TV receiver chassis are electrically

connected directly to one conductor of the AC

power cord. If an isolation transformer is not

used, these units may be safely serviced only

if the AC power plug is inserted so that the

chassis is connected to the ground side of the

AC source.

To confirm that the AC power plug is inserted

correctly, do the following: Using an AC

voltmeter, measure the voltage between the

chassis and a known earth ground. If the

reading is greater than 1.0V, remove the AC

power plug, reverse its polarity and reinsert.

Re-measure the voltage between the chassis

and ground.

12. Some TV chassis are designed to operate with

85 volts AC between chassis and ground,

regardless of the AC plug polarity. These units

can be safely serviced only if an isolation

transformer inserted between the receiver and

the power source.

13. Some TV chassis have a secondary ground

system in addition to the main chassis ground.

This secondary ground system is not

isolated from the AC power line. The two

ground systems are electrically separated by

insulating material that must not be defeated

or altered.

14. Components, parts and wiring that appear to

have overheated or that are otherwise

damaged should be replaced with parts that

meet the original specifications. Always

determine the cause of damage or overheat-

ing, and correct any potential hazards.

15. Observe the original lead dress, especially

near the following areas: Antenna wiring,

sharp edges, and especially the AC and high

voltage power supplies. Always inspect for

pinched, out-of-place, or frayed wiring. Do

not change the spacing between components

and the printed circuit board. Check the AC

power cord for damage. Make sure that leads

and components do not touch thermally hot

parts.

16. Picture Tube Implosion Warning:

The picture tube in this receiver employs

“integral implosion” protection. To ensure

continued implosion protection, make sure

that the replacement picture tube is the same

as the original.

17. Do not remove, install or handle the picture

tube without first putting on shatterproof

goggles equipped with side shields. Never

handle the picture tube by its neck. Some

“in-line” picture tubes are equipped with a

permanently attached deflection yoke; do not

try to remove such “permanently attached”

yokes from the picture tube.

18. Product Safety Notice:

Some electrical and mechanical parts have

special safety-related characteristics which

might not be obvious from visual inspection.

These safety features and the protection they

give might be lost if the replacement compo-

nent differs from the original—even if the

replacement is rated for higher voltage,

wattage, etc.

Components that are critical for safety are

indicated in the circuit diagram by shading,

( ) or ( ).

Use replacement components that have the

same ratings, especially for flame resistance

and dielectric strength specifications.

A replacement part that does not have the

same safety characteristics as the original

might create shock, fire or other hazards.

1-2 Servicing Precautions

1. Servicing precautions are printed on the

cabinet. Follow them.

2. Always unplug the unit’s AC power cord from

the AC power source before attempting to: (a)

Remove or reinstall any component or

assembly, (b) Disconnect an electrical plug or

connector, (c) Connect a test component in

parallel with an electrolytic capacitor.

3. Some components are raised above the printed

circuit board for safety. An insulation tube or

tape is sometimes used. The internal wiring is

sometimes clamped to prevent contact with

thermally hot components. Reinstall all such

elements to their original position.

4. After servicing, always check that the screws,

components and wiring have been correctly

reinstalled. Make sure that the portion around

the serviced part has not been damaged.

5. Check the insulation between the blades of the

AC plug and accessible conductive parts

(examples: metal panels, input terminals and

earphone jacks).

6. Insulation Checking Procedure: Disconnect the

power cord from the AC source and turn the

power switch ON. Connect an insulation

resistance meter (500V) to the blades of the AC

plug.

The insulation resistance between each blade

of the AC plug and accessible conductive parts

(see above) should be greater than 1 megohm.

7. Never defeat any of the B+ voltage interlocks.

Do not apply AC power to the unit (or any of

its assemblies) unless all solid-state heat sinks

are correctly installed.

8. Always connect a test instrument’s ground

lead to the instrument chassis ground before

connecting the positive lead; always remove

the instrument’s ground lead last.

9. When some parts inside the optical engine

(except lamp) are damaged, replace the whole

optical engine.

Precautions

Samsung Electronics 1-3

Warning 1 : First read the “Safety Precautions” section of this anual. If so e unforeseen circu stance creates a

conflict between the servicing and safety precautions, always follow the safety precautions.

Warning 2 : An electrolytic capacitor installed with the wrong polarity ight explode.

“CAUTION : Double-pole/neutral fusing”

1-3 Precautions for Electrostatically Sensitive Devices (ESDs)

1. Some semiconductor (“solid state”) devices

are easily damaged by static electricity. Such

components are called Electrostatically

Sensitive Devices (ESDs); examples include

integrated circuits and some field-effect

transistors. The following techniques will

reduce the occurrence of component damage

caused by static electricity.

2. Immediately before handling any semicon

ductor components or assemblies, drain the

electrostatic charge from your body by

touching a known earth ground. Alternatively,

wear a discharging wrist-strap device. (Be

sure to remove it prior to applying power—

this is an electric shock precaution.)

3. After removing an ESD-equipped assembly,

place it on a conductive surface such as

aluminum foil to prevent accumulation of

electrostatic charge.

4. Do not use freon-propelled chemicals. These

can generate electrical charges that damage

ESDs.

5. Use only a grounded-tip soldering iron when

soldering or unsoldering ESDs.

6. Use only an anti-static solder removal device.

Many solder removal devices are not rated as

“anti-static”; these can accumulate sufficient

electrical charge to damage ESDs.

7. Do not remove a replacement ESD from its

protective package until you are ready to

install it. Most replacement ESDs are

packaged with leads that are electrically

shorted together by conductive foam,

aluminum foil or other conductive materials.

8. Immediately before removing the protective

material from the leads of a replacement ESD,

touch the protective material to the chassis or

circuit assembly into which the device will be

installed.

9. Minimize body motions when handling

unpackaged replacement ESDs. Motions such

as brushing clothes together, or lifting a foot

from a carpeted floor can generate enough

static electricity to damage an ESD.

2-2 Description of Dyna ic Focus

Most large-screen video display devices that are using CRT (including CDT) usually apply the Dynamic

Focus (hereinafter D/F) circuit.

As CRT has non-spherical surface (perfect spherical surface = 1, non-spherical surface R>1), the distance

that the electron beam emitted from the electron gun reaches to the center of CRT is different from the one

that the electron beam reaches to the corners. (See Figure 1.)

Only the beam, which has the equal distance as the beam from the electron gun to the center of CRT

surface, can maintain the optimum focus.

By this reason, focus dagradation at corners occurs inevitably.

To recover this, the speed of the electron beam injected into the corners of CRT should increase and the

focus dagradation by the difference of distances can be compensated.

Increasing the voltage is used as a method of increasing the speed of the electron beam at the corners of

screen.

In this case, an ideal D/F voltage waveform is the form of parabola where the center of screen has low

voltage and the corners has the highest voltages.

The horizontal D/F waveform compensates the focus dagradation at left and right sides, but the vertical

D/F waveform does at top and bottom sides.

The horizontal D/F and vertical D/F waveforms are separately created and mix two signals to

compensate the focus of the whole screen.

And the vertical Dynamic Focus waveform is composed of the horizontal Dynamic Focus waveforms as

much as the number of scanning lines. (See Figure 2.)
