1. Precautions

Follow these safety, servicing and ESD precautions to prevent damage and protect against potential hazards such as electrical shock and X-rays.

1-1 Safety Precautions

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

2. When reinstalling the chassis and its assemblies, be sure to restore all protective devices, including 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.

4. Design Alteration Warning:

Never alter or add to the mechanical or electrical design of the 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.

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

Warning: Do not use an isolation transformer during this test. Use a leakagecurrent tester or a metering system that complies with American National Standards

Institute (ANSI C101.1, Leakage Current for

Appliances), and Underwriters Laboratories

(UL Publication UL1410, 59.7).

With the unit completely reassembled, plug the AC line cord directly into a 120V AC 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, etc.) and all exposed metal parts. Examples: Handle brackets, metal cabinets, screwheads and control shafts. The current measured should not exceed 0.5 milliamp. Reverse the powerplug prongs in the AC outlet and repeat.

Fig. 1-1 AC Leakage Test

6. Insulation Resistance Cold Check:

(1) With the unit's AC plug disconnected from the AC source, connect an electrical jumper across the two AC prongs. (2) Set the power switch to ON. (3) Measure the resistance between the shorted AC plug and any exposed metallic parts. Example:

Screwheads, antenna, control shafts or handle brackets.

If any of the exposed metallic parts has a return path to the chassis, the measured resistance should be between 1 and 5.2

megohms. If there is no return path, the measured resistance should be "infinite." If the resistance is outside these limits, a shock hazard might exist. See Figure 1-2

Fig. 1-2 Insulation Resistance Test

Samsung Electronics 1-1

Precautions

1-1 Safety Precautions (Continued)

7. 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 overheating, and correct any potential hazards

8. 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 no wires or components touch thermally hot parts.

9. 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 component differs from the original--even if the replacement is rated for higher voltage, wattage, etc.

10 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

Warning1: First read the "Safety Precautions" section of this manual. If some unforeseen circumstance creates a conflict between the servicing and safety precautions, always follow the safety 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 may be 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.

Precautions

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.

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).

2. Immediately before handling any semiconductor 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.

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.

4. Do not use freon-propelled chemicals.

These can generate electrical charges that damage ESDs.

9. Minimize body motions when handing 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.

Precautions

1-4 Special Precautions and Warning Labels for Laser Products (Continued)

1-4-1 Warnings

1. 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 30 cm from the surface of the objective lens on the optical pick-up block.

2. Do not attempt to handle the objective lens when the DISC is not on the tray.

1-4-3 Handling the Optical Pick-up

1. Static electricity from clothing or the body may cause electrostatic breakdown of the laser diode in the Optical Pickup. Follow this procedure:

2. Place a conductive sheet on the work bench

(i.e., the black sheet used for wrapping repair parts.) Note: The surface of the work bench should be covered by a copper ground plane, which is grounded.

1-4-2 Laser Diode Specifications

Material: GaAs+ GaAlAs

Wavelength: 760-800 nm

Emission Duration: Continuous

3. The repair technician must wear a wrist strap which is grounded to the copper sheet.

Laser Output: 0.2 mw (measured at a

1.6 mm distance from the objective lens surface on the optical pick-up block.)

4. To remove the Optical Pickup block:

Place the set on the conductive sheet, and momentarily touch the conductive sheet with both hands. (While working, do not allow any electrostatic sources--such as clothes--to touch the unit.)

5. Ground the "Short Terminal" (located on the

PCB, inside the Pickup Assembly) before replacing the Pickup. This terminal should be shorted whenever the Pickup Assembly is lifted or moved.

6. After replacing the Pickup, reopen the Short

Terminal. See diagrams below:

1-5 Special Precautions for HDD

* HDD Data Maintenance Step

1. Since the data on the HDD is weak to mechanical shock, place the HDD in a safe location that is free from mechanical shock once it is removed from the main unit.

2. In order to safe keep the data on the HDD, back up the data before the repair or make sure not to place the HDD near any electrical appliance that generates a strong magnetic field.

1. Definition of Home Theater

What is Home Theater?

Home theater system is the proper combination of audio and video system at home which enable you to enjoy more dynamic sound and vivid image in a wide screen of movie theater.

This effect can be implemented with wide screen, high quality projector, Dolby digital and DTS sound effects.

Now you can enjoy surround sound field wieh realistic presence and Dolby digital at your home as if you are in a movie theater.

As time goes by, home theater system has become recognized as a system that helps listen sound closer to the original sound rather than video. In this 21st century, most movie and animation films will be produced for home theater and reproduce sound closer to original sound.


2. Concept of Sound

What is Sound Range?

People can listen to the sounds with frequency between 200Hz~20.000Hz

As time goes by, home theater system has become recognized as a system that helps listen sound closer to the original sound rather than video. In this 21st century, most movie and animation films will be produced for home theater and reproduce sound closer to original sound.

What is Sound Pressure?

* A measure of how well speaker converts electric signal it receives to sound

* Unit of sound pressure is decibel and mainly measures the size of sound at 1 m away after sending 1 W power from speaker.

❋ High sound pressure doesn't necessary mean good performance

What is Timbre?

* How well the unique sound of musical instrument is expressed

* Better if violin and cello sound are accurately distinguished. Good timbre means high quality.


2. Concept of Sound

By reproducing standard channels used during soundtrack recording of movie, it outputs 3 sounds of movie (words / music / sound effects) from 6 different speakers and provides surround dynamic sound effects so that you can even feel the direction of sound.

5 channel

A

B

Center Speaker : Voice ( over 95%)

Front Speaker (L/R) : Music Sound

C Rear Speaker (L/R) : Sound Effect

0.1 channel

D Subwoofer : Low Sound Effect

* Power amp is embedded in active sub woofer

* Require separate amp since there is no amp in passive sub woofer

❋ No difference in performance of active sub woofer and passive sub woofer


4. Home Theater Sound Format

Overview

* As home theater has recently penetrated deep into consumer's market in Korea, Dolby digital and

DTS, the sound format for 5.1 channel home theater, are the mainstream in the market.

* Expanded type of 6.1 channel or 7.1 channel are recently released in the market, but there are not much DVD title that can support expanded type.

1958 1Ch Mono/ 2Ch Stereo

1982 Matrix 3Ch Dolby Surround

1987 Matrix 4Ch Dolby Pro Logic

1995 5.1Ch Dolby Digital

1997 DTS (Digital Theater System)

1999 Matrix 6.1Ch Dolby Digital Sourround EX

Home theater format...

Samsung Electronics

Stereo

Is used in general audio and analog TV and and consists of 2 channels, at front left/right

Dolby Surround

In this sound format, 4 audio channels (Front left / right / center / surround) are entered in 2 channel and reproduce in 4 channels through device with Dolby decoder.

Center channel is not completely separated so that it forms virtual center channel with help of front left / right channel.

14-4

Dolby Prologic

– Provide 4 channels (Front Left/Right/Center/Surround)

– Reinforced from Dolby Surround

① Center channel is completely separated

➁ Separation between channels gets higher

Dolby Digital

– Provide completely separate 5.1 channel

(Front Left/Right, Center, Rear Left/Right, Sub Woofer)

– Main sound format of home theater

– Reinforced from Dolby Prologic

– Rear surround left/right channels give different sound

– Support sub woofer reinforcing Bass

❋ Dolby Digital is also called AC-301

AC-3(Audo-Coding-3) : 3rd digital audio coding Dolby Research Center has developed.

DTS(Digital Theater System)

– Technology of providing 5.1 channel sound, higher quality than

Dolby Digital

– Home appliance produced to apply system installed at 1,800 theaters throughout the world.

✪ Comparison of DTS and Dolby Digital(DD)


Dolby Prologic

– Latest technology reproducing music CD recorded in 2 channel, cassette tape and video tape made in Dolby Prologic into 5.1 channel.

– Surround speaker that makes you feel more natural, deeper and wider than existing Dolby Prologic.

(Ex-Profound sound adds more realistic presence from 5 speakers and sub woofer when you watch soccer match.)

DTS (Digital Theater System)

THX (Abbreviation of Tomlison Holman's Experiment)

– THX is not a sound format like a Dolby or DTS, but is a standard of sound. Like standard KS mark in Korea, THX means good certification in sound effects.

– THX issues certificate when a movie, theater or home theater system satisfy proper standards.
