NEW FUNCTIONS OF HDD/DVD-RECORDER
• HDMI
HDMI IS THE SPECIFICATION FOR THE HIGH-DEFINITION MULTIMEDIA INTERFACE. HDMI IS PROVID­ED FOR TRANSMITTING DIGITAL TELEVISION AUDIOVISUALSIGNALS FROM HDD-DVD RECORDER TO TELEVISION SETS, OTHER VIDEO DISPLAYS. HDMI CAN CARRY HIGH QUALITY MULTI-CHANNEL AUDIO DATAAND 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 CHANNELAND IS USED BY THE
RECEIVER AS A FREQUENCY REFERENCE FOR DATA RECOVERY ON THE THREE TMDS DATA CHAN­NELS.
VIDEO DATAIS CARRIED AS ASERIES 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 FORMATS. IN ALLTHREE CASES, UP TP 24 BITS PER
PIXEL CAN BE TRANSFERRED.
FAST DUBBING
DUBBING MEANS ACOPYING 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 RECORDING 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(DVD­RW) TO HDD , AND ONLY NORMAL DUBBING AVAILABLE WHEN COPYING VIDEO MODE DISC
(DVD+R/RW, DVD-R) TO HDD

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 Electronics 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 Electronics 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.
Remembers 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) Disconnection or reconnecting any internal electrical
plug or other electrical connection.
(3) Connecting a test substitute in parallel with an elec-
trolytic 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 solid-state device heat sinks are cerrectly installed.
6. Always connect test instrument ground lead to the
appropriate ground before connection 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 including 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 grouned-tip soldering iron to solder or unsolder ES devices.
4. Use only an anti-static solder removal device. Some solder removal devices not classified a “anti-static” can generate electrical charges sufficient to damage ES devices.
5. Do not use freon-propelled chemicals. These can generate electrical charge sufficient to damage ES devices.
6. Do not remove a replacement ES device from its protec tive 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.)

The format that records data through the creation of recorded marks by changing the organic dye material with a laser beam.
[ 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 CD-ROM.
[ Playback ]
Signals are read with the differences of the reflection of a laser from pits.

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

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.

4. OPTICAL POWER SETTING
<Test for checking DVD LD and CD LD>
When you change the Travers ass°Øy(including pick-up) or loader PCB, you must do the laser power setting to match
pick-up and loader PCB.
1) DVD LD power setting
• Select the DVD in the ‘Select Laser Diode’
• Press (Read Power On, Strong Read light)
•Measure optical read Power.
•Write read power value.
• In case of ,
you are able to measure the power through same procedure.
(caution) Don’t watch light directly.
• When you finish optical power measurement,
press button(LD Off).
•Press button.(save to ERPROM)
2) CD LD Power Setting
• Select the CD in the ‘Select Laser Diode’
• Press .
•Measure optical read Power.
•Write Read Power value.
•Press button(save to ERPROM)
*** In case of CD power setting of RS-01A, loader don’t need to set up
write power. Although NMP, MP,Erase and HC power is N.G when you press setup, please ignore the N.G message. Because of RS-01A only support reading function about CD-R/RW.
* Look at reference sheet to test Optical Power. **Power value is ß— unit. Value is read power X 100.

5. CONFIRM OPTICAL POWER SETTING PARAMETER
LD Test result is ok, but Loader performance is bad.
1. Check ALPC parameter value
1) Press button to open ‘Results Display’ dialog.
2) Press button.
- We can see optical power setting value.
- Write optical Power Setting value to paper.
- Adjust power setting again.
- Compare original parameter to new parameter.
- if parameter value is different highly, original value is wrong or optical power may change.
- But pick-up LD test is all ok , just adjust optical power setting again.
