NEW FUNCTIONS OF HDD/DVD RECORDER

• HDMI

HDMI IS THE SPECIFICATION FOR THE HIGH-DEFINITION MULTIMEDIA INTERFACE. HDMI IS PROVIDED
FOR TRANSMITTING DIGITAL TELEVISION AUDIOVISUAL SIGALS FROM HDD-DVD RECODER TO
TELEVISION SETS, OTHER VIDEO DISPLAYS. HDMI CAN CARRY HIGH QUALITY MULTI-CHANNEL AUDIO
DATA AND CAN CARRY ALL STANDARD AND HIGH DEFINITION CONSUMER ELECTRONICS VIDEO
FORMATS. CONTENT PROTECTION TECHNOLOGY IS AVAILABLE. HDMI CAN ALSO CARRY CONTROL
AND STATUS INFORMATION IN BOTH DIRECTIONS.

<< OPERATING >>

AUDIO, VIDEO AND AUXILIARY DATA IS TRANSMITTED ACROSS THE THREE TMDS DATA CHANNELS.
THE VIDEO PIXEL CLOCK IS TRANSMITTED ON THE TMDS CLOCK CHANNEL AND USED BY THE
RECEIVER AS A FREQUENCY REFERENCE FOR DATA RECOVERY ON THE THREE TMDS DATA
CHANNELS.
VIDEO DATA IS CARRIED AS A SERIES OF 24-BIT PIXELS ON THE THREE TMDS DATA CHANNELS.
TMDS ENCODING CONVERTS THE 8BIT PER CHANNEL INTO THE 10BIT DC-BALANCED.
VIDEO PIXEL RATES CAN RANGE FROM 25MHz TO 165MHz. THE VIDEO PIXELS CAN BE ENCODED IN
EITHER RGB, YCbCr 4:4:4 OR YCbCr 4:2:2 FORAMTS. IN ALL THREE CASES, UP TP 24 BITS PER PIXEL
CAN BE TRANSFERRED.

FAST DUBBING

DUBBING MEANS A COPYING FUNCTION BETWEEN HDD TO DVD DISCS.
COPYING BETWEEN HDD TO DVD IS A COMPLETELY DIGITAL PROCESS AND THEREFORE INVOLVES
NO LOSS OF QUALITY IN THE AUDIO OR VIDEO. SO THIS MEANS THAT COPYING CAN BE CARRIED OUT
AT THE MAXIMUM SPEED POSSIBLE.

<< DUBBING SPEED RATE >>

NORMAL DUBBING : SPEED RATE MAX X1
FAST DUBBING : SPEED RATE MAX X4

WHEN FAST DUBBING FROM HDD TO DVD, THE SPEED OF COPYING DEPENDS ON THE RECODING
MODE AND THE KIND OF USING THE DVD DISC, AND THIS MODE IS NOT AVAILABLE FOR EDITED VIDEO
TITLE IN HDD.
WHEN FAST DUBBING FROM DVD TO HDD, ONLY AVAILABLE WHEN COPYING VR MODE DISC(DVD-RW)
TO HDD, AND ONLY NORMAL DUBBING AVAILABLE WHEN COPYING VIDEO MODE DISC(DVD+RW/RW,
DVD-R) TO HDD.

PRODUCT SAFETY SERVICING GUIDELINES FOR HDD/DVD RECORDER PRODUCTS

IMPORTANT SAFETY NOTICE

This manual was prepared for use only by properly trained audio-video service
technicians.
When servicing this product, under no circumstances should the original design be
modified or altered without permission from LG Corporation. All components should
be replaced only with types identical to those in the original circuit and their physical
location, wiring and lead dress must conform to original layout upon completion of
repairs.

Special components are also used to prevent x-radiation, shock and fire hazard.
These components are indicated by the letter “x” included in their component
designators and are required to maintain safe performance. No deviations are
allowed without prior approval by LG Corporation.
Circuit diagrams may occasionally differ from the actual circuit used. This way,
implementation of the latest safety and performance improvement changes into the
set is not delayed until the new service literature is printed.

CAUTION

: Do not attempt to modify this product in any way. Never perform
customized installations without manufacturer’s approval. Unauthorized
modifications will not only void the warranty, but may lead to property damage or user
injury.

Service work should be performed only after you are thoroughly familiar with these
safety checks and servicing guidelines.

GRAPHIC SYMBOLS

The exclamation point within an equilateral triangle is intended to alert
the service personnel to important safety information in the service
literature.
The lightning flash with arrowhead symbol within an equilateral
triangle is intended to alert the service personnel to the presence of
noninsulated “dangerous voltage” that may be of sufficient magnitude
to constitute a risk of electric shock.
The pictorial representation of a fuse and its rating within an equilateral
triangle is intended to convey to the service personnel the following
fuse replacement caution notice:
CAUTION : FOR CONTINUED PROTECTION AGAINST RISK OF
FIRE, REPLACE ALL FUSES WITH THE SAME TYPE AND
RATING AS MARKED NEAR EACH FUSE.

SERVICE INFORMATION

While servicing, use an isolation transformer for protection from AC line shock. After
the original service problem has been corrected, make a check of the following:

FIRE AND SHOCK HAZARD

1. Be sure that all components are positioned to avoid a possibility of adjacent

component shorts. This is especially important on items trans-ported to and from
the repair shop.

2. Verify that all protective devices such as insulators, barriers, covers, shields, strain

reliefs, power supply cords, and other hardware have been reinstalled per the
original design. Be sure that the safety purpose of the polarized line plug has not
been defeated.

3. Soldering must be inspected to discover possible cold solder joints, solder

splashes, or sharp solder points. Be certain to remove all loose foreign particles.

4. Check for physical evidence of damage or deterioration to parts and components,

for frayed leads or damaged insulation (including the AC cord), and replace if
necessary.

5. No lead or component should touch a high current device or a resistor rated at 1

watt or more. Lead tension around protruding metal surfaces must be avoided.

6. After reassembly of the set, always perform an AC leakage test on all exposed

metallic parts of the cabinet (the channel selector knobs, antenna terminals,
handle and screws) to be sure that set is safe to operate without danger of
electrical shock. DO NOT USE A LINE ISOLATION TRANSFORMER DURING
THIS TEST. Use an AC voltmeter having 5000 ohms per volt or more sensitivity
in the following manner: Connect a 1500 ohm, 10 watt resistor, paralleled by a .15
mfd 150V AC type capacitor between a known good earth ground water pipe,
conduit, etc.) and the exposed metallic parts, one at a time. Measure the AC
voltage across the combination of 1500 ohm resistor and .15 mfd capacitor.
Reverse the AC plug by using a non-polarized adaptor and repeat AC voltage
measurements for each exposed metallic part. Voltage measured must not
exceed 0.75 volts RMS. This corresponds to 0.5 milliamp AC. Any value
exceeding this limit constitutes a potential shock hazard and must be corrected
immediately.

TIPS ON PROPER INSTALLATION

1. Never install any receiver in a closed-in recess, cubbyhole, or closely fitting shelf
space over, or close to, a heat duct, or in the path of heated air flow.

2. Avoid conditions of high humidity such as: outdoor patio installations where dew
is a factor, near steam radiators where steam leakage is a factor, etc.

3. Avoid placement where draperies may obstruct venting. The customer should also
avoid the use of decorative scarves or other coverings that might obstruct
ventilation.

4. Wall- and shelf-mounted installations using a commercial mounting kit must follow
the factory-approved mounting instructions. A product mounted to a shelf or
platform must retain its original feet (or the equivalent thickness in spacers) to
provide adequate air flow across the bottom. Bolts or screws used for fasteners
must not touch any parts or wiring. Perform leakage tests on customized
installations.

5. Caution customers against mounting a product on a sloping shelf or in a tilted
position, unless the receiver is properly secured.

6. A product on a roll-about cart should be stable in its mounting to the cart.
Caution the customer on the hazards of trying to roll a cart with small casters
across thresholds or deep pile carpets.

7. Caution customers against using extension cords. Explain that a forest of
extensions, sprouting from a single outlet, can lead to disastrous consequences to
home and family.

SERVICING PRECAUTIONS

CAUTION: Before servicing the HDD / DVD RECORDER
covered by this service data and its supplements and
addends, read and follow the SAFETY PRECAUTIONS.
NOTE: if unforeseen circumstances create conflict between
the following servicing precautions and any of the safety
precautions in this publications, always follow the safety
precautions.
Remember Safety First :

General Servicing Precautions

1.Always unplug the HDD / DVD RECORDER AC power
cord from the AC power source before:
(1) Removing or reinstalling any component, circuit board,

module, or any other assembly.

(2) Disconnecting or reconnecting any internal electrical

plug or other electrical connection.

(3) Connecting a test substitute in parallel with an

electrolytic capacitor.
Caution : A wrong part substitution or incorrect polarity
installation of electrolytic capacitors may result in an
explosion hazard.

2.Do not spray chemicals on or near this HDD / DVD
RECORDER or any of its assemblies.

3.Unless specified otherwise in this service data, clean
electrical contacts by applying an appropriate contact
cleaning solution to the contacts with a pipe cleaner,
cotton-tipped swab, or comparable soft applicator.
Unless specified otherwise in this service data, lubrication
of contacts is not required.

4.Do not defeat any plug/socket B+ voltage interlocks with
whitch instruments covered by this service manual might
be equipped.

5.Do not apply AC power to this HDD / DVD RECORDER
and / or any of its electrical assemblies unless all solidstate
device heat sinks are correctly installed.

6.Always connect the test instrument ground lead to an
appropriate ground before connecting the test instrument
positive lead. Always remove the test instrument ground
lead last.

Insulation Checking Procedure

Disconnect the attachment plug from the AC outlet and turn
the power on. Connect an 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 (Note 1) should be more than
1Mohm.
Note 1 : Accessible Conductive Parts include Metal panels,
Input terminals, Earphone jacks,etc.

Electrostatically Sensitive (ES) Devices

Some semiconductor (solid state) devices can be damaged
easily by static electricity. Such components commonly are
called Electrostatically Sensitive (ES) Devices. Examples of
typical ES devices are integrated circuits and some field
effect transistors and semiconductor chip components.
The following techniques should 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 ES
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 ES devices.

4.Use only an anti-static solder removal device. Some solder
removal devices not classified as “anti-static” can generate
electrical charges sufficient to damage ES devices.

5.Do not use freon-propelled chemicals. These can generate
an electrical charge sufficient to damage ES devices.

6.Do not remove a replacement ES device from its
protective package until immediately before you are ready
to install it. (Most replacement ES devices are packaged
with leads electrically shorted together by conductive
foam, aluminum foil,or comparable conductive material).

7.Immediately before removing the protective material from
the leads of a replacement ES 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 ES devices. (Normally 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 ES device.)

1) DVD-ROM

2) Recording format using organic dye material
(DVD-R / DVD+R)

The format that records data through the creation of recorded marks by changing the organic dye
material with a laser beam.

• Disc structure

• Recording principles

[ Recording ]

Recording is done by changing the organic dye layer and the substrate with a laser When a strong laser
is applied to a disc, the temperature of the organic dye material goes up, the dye is decomposed and
the substrate changes at the same time. At this time, a durable bit is created as is the case with a CD­ROM.

[ Playback ]

Signals are read with the differences of the reflection of a laser from pits.

4-19

3) Recording format using phase-change recording material
(DVD-RW / DVD+RW)

Data is recorded by changing the recording layer from the amorphous status to the crystalline status,
and played back by reading the difference of the reflection coefficient.
Amorphous : Non-crystalline.

• Disc structure

• Recording principles

[ Recording ]

When a high-power laser is applied to the recording material, it melts and then becomes amorphous with
a low reflection coefficient when it quickly cools off. When a mid-power laser is applied to heat gradually
the recording material and then gradually cools it off, it becomes crystal with a high reflection coefficient.

[ Playback ]

A low-power laser is used for playback. The amount of reflected light depends on the status (amorphous
or crystalline) of the recording material. This is detected by an optical sensor.

4-20

To make recordings, it is necessary to modulate the write pulse, which is called “Write Strategy”.
There can be many types in Write Strategy. Typically Write Strategy for DVD R has NMP(Non Multi-Pulse)

type and MP(Multi-Pulse) type. In NMP type each single mark is created by subsequent separated short
pulses. In MP type each single mark is created by one continuous pulse.

Write Strategy for DVD RW has Type 1 and Type2. In Type 1 the mark with nT width is created by one top
pulse and (n-2) multi-pulses. Thus mark 3T is made by one top pulse and one multi-pulse. In Type 2 the mark
with nT width is created by one top pulse and (n-3) multi-pulses. Thus mark 3T is made by one top pulse
only.

RL-02A uses MP type Write Strategy for DVD R and Type 1 for DVD RW as shown below.
