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 remove 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 fishpapers, adjustment and compartment covers/shields, and isolation resis­tor/capacitor networks. Do not 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
throught 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 a 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 for Appliances and Underwriters Laboratories (UL) 1270 (40.7). With the instrument’s AC switch first in the ON position and then in the OFF position, measure from a known earth ground (metal waterpipe, 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 0.5 mil­lamp. Reverse the instrument power cord plug in the outlet and repeat the test. See Figure 1-1.
Fig. 1-1 AC Leakage Test
Any measurements not within the limits specified herein indicate a potential shock hazard that must be ellminated 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) Measure the resistance with an ohmmeter between the jumpered AC plug and all exposed metallic 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 reading must be infinite. If the reading is not within the limits specified, there is the possibility of a shock hazard, and the instrument must be repared and rechecked before it is returned to the customer. See figure 1-2.

CAUTION: Before servicing Instruments covered by this service manual and its supplements, read and fol­low the Safety Precautions section of this manual.
Note: If unforseen circument create conflict between the following servicing precautions and any of the safety precautions, always follow the safety precau­tions. Remember: Safety First.
1-2-1 General Servicing Precautions
(1) a. Always unplug the instrument’s AC power cord
from the AC power source before (1) removing 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/socker B+ voltage inter-
locks 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 solid­state 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 retings. Components identified by shading, by( x ) 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 wil­ing 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, corponents, 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.
1-2-2 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: Accesible conductive parts include metal pan­els, input terminals, earphone jacks, etc.
1-2 Servicing Precautions

Electrostatically Sensitive Devices (ESD)
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electro stati­cally Sensitive Devices(ESD). Examples of typical ESD devices are integrated circuits and some fieldef­fect 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 aharge 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 ouly 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 damge 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 condutive foam, aluminum foil or comparable conductive materials).
(7) Immediately before removing the protective mate-
rials from the leads of a replacement 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 unpack-
aged 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 electrictity suffcient to damage an ESD device).
1-3 ESD Precautions
Samsung Electronics 1-5
* The laser diode in the optical pick up may suffer elec-
trostatic 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) Romove 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.

2-2 Chip Replacement
1) Do not touch the part body directly with the sol­dering iron. ICs, especially TSOP, are easily dam­aged by heat.
2) Use care regarding soldering iron tip and avoid repidly heating parts. Some parts can be damaged by sudden heating. Preheat the part at about 100°… for several minutes before installing it.
3) Use soldering tip temperature of about 240°… or larger parts, use a slightly higher temperature (about 280°…).
4) The thin(0.3mm)solder for miniature parts does not contain adequate flux. Supplementary flux is thus needed in most cases.
5) Use care not to damage the circuit pattern, espe­cially when removing.
6) Because of the many pins, cleanliness of the pat­tern is extremely important after removing the IC.
7) Use care to avoid solder bridges. Remove any that occurs.
8) Position the part carefully. They will also affect the soldering operation. Be very precise in positioning the IC. Soldering opposite pins first holds the IC in place and makes soldering the other pins easier.
9) Do not reuse removed parts.
10) Check for solder joints, especially miniature parts with small lead.
11) A defective trimming resistor cannot be adjusted externally . Replace with an ordjnary variable resis­tor.
12) It is important to inspect the work with a magnifier. Check after installing (cold solder joints, etc.).

You can see the menu screen only when a menu is contained on the disc.
4-2-2 Use of Setup Menu
1) Screen Menu Language You can select the menu language recorded on the disc If the selected menu language is not recorded on the disc, the original pre-recorded language is selected.
2) Audio Language If you set up the audio language in advance, you can watch movies with pre-selected audio. You don*t need to set
up audio every time you watch a movie.
If the selected audio language is not recorded on the disc, the original pre recorded audio language is selected.
3) Subtitle Language If you set up the subtitle language in advance, it will come up automatically every time you watch a movie. If the selected subtitle is not recorded on the disc, the original pre-recorded Subtitle is selected.
4) Screen Angle Mark This function allows you to turn the screen angle mark on or off in order to view various screen angles. If your DVD disc is encoded with screen angles, angle mark will be displayed when the screen angle mark is set to *ON*
5) Parental Level
The Parental Level control allows users to set the level necessary to prevent children from viewing unsuitable movies
such as those with violence, adult subject matter, etc. ... There are up to 8 parental levels on a disc and they can be
used to prevent the viewing of certain movies. For Example, Level 1 is the "Kids Safe" level and is the most restric­tive. Only youth oriented movies will be played back when the player is set to Level 1. Level 8 is the "Adult" level and is the least restrictive. All types of movies will play when the player is set to this level.
The Parental Level Control function is compatible only with parental level encoded discs. If you forget your password, press the CLEAR button 3 times successively while in the *ENTER PASSWORD* *1111* is the original password that has been encrypted in the player by the manufacturer.
6) Screen Ratios
