When the AD board is in DPMS state: 1.1 The IP has been designed so that it operates with a power consumption of less than 0.6W of. 1.2 The Scaler consumes power up to 27mA 1.3 The power to the panel is switched off 1.4 The MCU consumes power up to 23mA. --> The total current consumption to the DPMS is less then 60mA and the total power consumption is 0.6W + 5V*60mA = 0.9W so that the total power consumption is less than 1W. 2. When the AD board is operating normally: 2.1 The maximum power consumption of the panel lamps is described below (It may vary depending on the panel manufacturer) 17" : 4*(7.5mA*650mVrms)=4*4.9=19.6W 19: : 4*(7.5mA*720mVrms)=4*5.4=21.6W 2.2 The power consumption of the Panel Control board is as follows: 5V*720mA=3.6W 2.3 The power consumption of the Scaler is as follows: 3.3V*245mA + 1.8V*300mA = 1.35W 2.4 The power consumption of the MCU is as follows: 5V*44mA =0.22W 13-1 13 Circuit Descriptions 13-1-2 Main Board Parts 1. Inverter: A conversion device that converts DC rated voltage/current to high ones necessary for the panel lamp. 2. DC/DC(Regulator): General term for DC to DC converting devices. The IP board receives 5V and outputs 1.8 or 3.3V that is supplied to the scaler (SE56AWL). 3. Power MosFET: The IP board receives 5V and outputs a lower voltage in DPMS mode and supplies the whole 5V for the panel operating board in normal conditions. In that case, the switching of Power MosFET is controlled by Micom. 4. Scaler: Receives the digital TMDS and analog R,G,B signals and convert them to proper resolutions using up- or down- scaling that are transferred to the panel in the LDVS formats. 5. Crystal(Oscillator): Use one 24MHz oscillator externally to supply power to both MCU and Scaler at the same time. 6. MCU & EEPROM: I2C is a two-way serial bus of two lines that supports communications across the integrated circuits as well as between MCU, Scaler and EEPROM. In particular, MCU and Scaler (SE56AWL) use the DDR direct bus for mutual communications, which is an effective, speedy system because it allows 4 additional address/data lines compared to the old serial systems. 7. Function Key: A certain keystroke generates a certain electrical potential, which is transferred into ADC input port of the MCU and then converted to a digital value by the A/D converter of the chip. The digital value (data) is a clue to which key is entered. In practical, the voltage levels are set as below. 13-2 13 Circuit Descriptions 13-1-3 IP BOARD BLOCK(POWER) Parts 13-1-4 IP BOARD BLOCK( INVERTER ) Parts I BO A RD P B LO C K ( I V ERT ER ) N I V ERT ER PA RT N D C I put nput n + 1 dc 13V POWER DC INPUT Lamp FULL BRIDGE CIRCUIT Lamp Lamp Lamp + 5V d 5V dc A D I + 3. dc M . 3V 3 BD I + 4. dc M . 5V ON/OFF DIM INPUT INVERTER CONTROL IC DRI

MagicBright button MagicBright is a new feature providing optimum viewing environment depending on the contents of the image you are watching. Currently six different modes are available: Custom, Text, Internet, Game, Sport and Movie. Each mode has its own pre-configured brightness value. You can easily select one of six settings by simply pressing MagicBright control buttons. 1) Custom Although the values are carefully chosen by our engineers, the pre-configured values may not be comfortable to your eyes depending on your taste. If this is the case, adjust the brightness and contrast by using the OSD menu. 2) Text : Normal brightness For documentations or works involving heavy text. 3) Internet : Medium brightness For working with a mixture of images such as text and graphics. 4) Game For watching motion pictures such as a game. 5) Sport For watching motion pictures such as a sport. 6) Movie : High brightness For watching motion pictures such as a DVD or Video CD. 3.

1 Precautions 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. For continued safety, do not attempt to modify the circuit board. Disconnect the AC power and DC power jack before servicing. 1-1-2 Servicing the LCD Monitor 1. 2. When servicing the LCD Monitor, 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. 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 resistorcapacitor 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). 4. Figure 1-1. Leakage Current Test Circuit 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, 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. 2. 3. 1-1-4 Product Safety Notices Some electrical and mechanical parts have special safetyrelated 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. 1-1 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 Precautio
