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

1-1 Safety Precautions
1-1-1 Warnings
1. 2. 3. For continued safety, do not attempt to modify the circuit board. Disconnect the AC power and DC Power Jack before servicing. When the chassis is operating, semiconductor heatsinks are potential shock hazards.
DEVICE UNDER TEST TEST ALL EXPOSED METAL SURFACES (READING SHOULD NOT BE ABOVE 0.5mA)

LEAKAGE CURRENT TESTER

1-1-2 Servicing the LCD Monitor
1. When servicing the LCD Monitor, remove the static charge by connecting a 10k ohm resistor in series with an insulated wire (such as a test probe) between the chassis and the anode lead. (Disconnect the AC line cord from the AC outlet.) It is essential that service technicians have an accurate voltage meter available at all times. Check the calibration of this meter periodically.

ALSO TEST WITH PLUG REVERSED (USING AC ADAPTER PLUG AS REQUIRED)

EARTH GROUND

Figure 1-1. Leakage Current Test Circuit
4. With the unit completely reassembled, plug the AC line cord directly into a 120V AC outlet. With the unitÕs 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: 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.

1-1-3 Fire and Shock Hazard
Before returning the monitor to the user, perform the following safety checks: 1. Inspect each lead dress to make certain that the leads are not pinched or that hardware is not lodged between the chassis and other metal parts in the monitor. Inspect all protective devices such as nonmetallic control knobs, insulating materials, cabinet backs, adjustment and compartment covers or shields, isolation resistor-capacitor networks, mechanical insulators, etc. 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 (ANSI C101.1, Leakage Current for Appliances), and Underwriters Laboratories (UL Publication UL1410, 59.7).

2.

1-1-4 Product Safety Notices
Some electrical and mechanical parts have special safety-related characteristics which are often not evident from visual inspection. The protection they give may not be obtained by replacing them with components rated for higher voltage, wattage, etc. Parts that have special safety characteristics are identified by ! on schematics and parts lists. A substitute replacement that does not have the same safety characteristics as the recommended replacement part might create shock, fire and / or other hazards. Product safety is under review continuously and new instructions are issued whenever appropriate.

1 Precautions

1-2 Servicing Precautions
WARNING: Caution: Note: An electrolytic capacitor installed with the wrong polarity might explode. Before servicing units covered by this service manual, read and follow the Safety Precautions section of this manual. If unforeseen circumstances create conflict between the following servicing precautions and any of the safety precautions, always follow the safety precautions.

1-2-1 General Servicing Precautions
1. Always unplug the unitÕs AC power cord from the AC power source and disconnect the DC Power Jack before attempting to: (a) remove or reinstall any component or assembly, (b) disconnect PCB plugs or connectors, (c) connect a test component in parallel with an electrolytic capacitor. 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. After servicing, always check that the screws, components and wiring have been correctly reinstalled. Make sure that the area around the serviced part has not been damaged. 4. Check the insulation between the blades of the AC plug and accessible conductive parts (examples: metal panels, input terminals and earphone jacks). Insulation Checking Procedure: Disconnect the power cord from the AC source and turn the power switch ON. Connect an insulation resistance meter (500 V) 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. 6. Always connect a test instrumentÕs ground lead to the instrument chassis ground before connecting the positive lead; always remove the instrumentÕs ground lead last.

1-3 Electrostatically Sensitive Devices (ESD) Precautions
Some semiconductor (solid state) devices can be easily damaged by static electricity. Such components are commonly called Electrostatically Sensitive Devices (ESD). Examples of typical ESD devices are integrated circuits and some fieldeffect transistors. The following techniques will reduce the incidence of component damage caused by static electricity. 1. 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 wriststrap device. To avoid a shock hazard, be sure to remove the wrist strap before applying power to the monitor. After removing an ESD-equipped assembly, place it on a conductive surface such as aluminum foil to prevent accumulation of an electrostatic charge. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ESDs. Use only a grounded-tip soldering iron to solder or desolder ESDs. Use only an anti-static solder removal device. Some solder removal devices not classified as Òanti-staticÓ can generate electrical charges sufficient to damage ESDs. 8. 6. 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. 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.

7.

3.

Caution: Be sure no power is applied to the chassis or circuit and observe all other safety precautions.
Minimize body motions when handling unpackaged replacement ESDs. Motions such as brushing clothes together, or lifting your foot from a carpeted floor can generate enough static electricity to damage an ESD.

4-2 Microprocessor Controls and Functions
This monitor has no Òservice onlyÓ micom controls. Should there be a problem with the microprocessor, replace the entire circuit board. There are, however, user accessible adjustment features that are described below. This monitor has factory preset display settings for each of the signals listed in the standard display modes Timing Chart (see pages 3-3 and 3-4). As a result, when the monitor senses one of the standard signal timings, it automatically adjusts to an optimum size and position. However, the user may wish to adjust the monitor to their own preferred settings rather than use those preset at the factory. The monitor saves up to 16 user defined settings.

4-2-1 OSD Window
The adjustable features described below all use the on-screen menu system. 1. Push the button to open the display the onscreen menu. 2. Use the or button to change an adjustment icon, use the button to highlight an adjustment icon, then use the + or Ð buttons to make the adjustments. 3. To select another adjustment on the same screen, use the or button to move to the next selection. 4. When you are done making adjustments on an adjustment icon, push the EXIT button. 5. When you are done making all adjustments, push the EXIT button. Table 4-2 shows the adjustment types and their icons.

Note 1: This monitor automatically returns to normal operation when horizontal and vertical sync return. This occurs when you move the computer's mouse or press a key on the keyboard. Note 2: This monitor is EPA ENERGY STAR¨ compliant and NUTEK compliant when used with a computer equipped with VESA DPMS functionality. If your computer system cannot support a display power management function, you can purchase an optional DPMS software program to enable the power saving function. Please contact Samsung or your dealer for more information. Note 3: For energy conservation, turn your monitor OFF when it is not needed, or when leaving it unattended for long periods. Note 4: Audio Part is operated separately by control button.
