13 Circuit Descriptions 13 Circuit Descriptions 13-1 Overall Block Structure 13-1-1 Power Tree 1. 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 37mA 1.3 The power to the panel is switched off 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*(7.0mA*650Vrms)=4* 4.55W=18.2W 2.2 The power consumption of the Panel Control board is as follows: 5V*645mA=3.23W 2.3 The power consumption of the Scaler is as follows: 3.3V*204mA + 1.8V*145mA = 0.93W 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 (TSUM16AL-LF). 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 analog R,G,B signals and convert them to proper reso- lutions using up- or down- scaling that are transferred to the panel in the LDVS formats. 5. Crystal(Oscillator): Use one 14.318MHz oscillator externally to supply power to both MCU and Scaler at the same time. 6. Scaler & EEPROM: I2C is a two-way serial bus of two lines that supports communications across the integrated circuits as well as between FLASH and EEPROM. In particular, MCU(TSUM16AL-LF) and use the SDR direct bus for mutual communications, which is an effective, speedy system because it allows 4 additional address/data lines com- pared 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 con- verted to a digital value by the A/D converter of the chip. The digital value (data) is a clue to which key is entered. 13-2 13 Circuit Descriptions 13-1-3 IP Board Part(Power) Schematic Diagrams 13-3 13 Circuit Descriptions 13-2 IP BOARD part(Inverter Part) Vin voltage (+14.2V) DC to DC (+14.2V to 5.0V) Brightness control signal ON/OFF MosFET U501 MosFET U502 Transformer T502 CCFL1 CCFL2 Transformer T501 CCFL1 CCFL2 CCFL PWM Control IC IC501 Voltage feedback Current feedback 13-4

It can be used from Main PBA to Panel. -Inverter Device that supplies Power to LCD panel lamp. This device generates about 1,500~2,000V. AC Adapter Device that converts AC(90V~240V) to DC(+12V or 14V) -DDC(Display data channel) It is a communication method between a Host Computer and related equipment. It enables Plug and Play between PC and Monitor. -SMPS(Switching Mode Power Supply) Switching Mode Power supply. This design technol- ogy is used to step up/down the input power by switching on/off -EDID Extended Display Identification Data PC can recog- nize monitor information, such as Product data, Product name, Display mode, Serial number, Signal source, etc. Data is recognized via DDC Line linking PC and Monitor. -FRC(Frame Rate Controller) Technology that changes the number of frames dis- played on screen per second. TFT-LCD panel requires 60 frames per second. This technology is needed to convert input image to 60 frames per second regardless input frame quan- tity. -Dot Pitch The image on a monitor is composed of red, green and blue dots. The closer the dots, the higher the resolution. The distance between two dots of the same color is called the 'Dot Pitch'. Unit: mm -Image Scaler Technology that convert various input resolution to other resolution.(ex. 640* 480 to 1024*768) -Auto Configuration(Auto adjustment) This is an algorithm to adjust monitor to optimum condition by pushing one key. -Vertical Frequency The screen must be redrawn several times per sec- ond in order to create and display an image for the user. The frequency of this repetition per second is called Vertical Frequency or Refresh Rate. Unit: Hz Example: If the same light repeats itself 60 times per second, this is regarded as 60 Hz. -Horizontal Frequency The time to scan one line connecting the right edge to the left edge of the screen horizontally is called Horizontal Cycle. The inverse number of the Horizontal Cycle is called Horizontal Frequency. Unit: kHz -OSD(On Screen Display) Customers can easily control the screen settings using the OSD. 14-1 14 Reference Infomation -Interlace and Non-Interlace Methods Showing the horizontal lines of the screen from the top to the bottom in order is called the NonInterlace method while showing odd lines and then even lines in turn is called the Interlace method.

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
