Warning: To prevent fire or shock hazard, do not expose the monitor to rain or moisture. Dangerous high voltages are present inside the monitor. Do not open the cabinet. Refer servicing to qualified personnel only. 4 Precautions z Do not use the monitor near water, e.g. near a bathtub, washbowl, kitchen sink, laundry tub, swimming pool or in a wet basement. z Do not place the monitor on an unstable trolley, stand, or table. If the monitor falls, it can injure a person and cause serious damage to the appliance. Use only a trolley or stand recommended by the manufacturer or sold with the monitor. If you mount the monitor on a wall or shelf, uses a mounting kit approved by the manufacturer and follow the kit instructions. z Slots and openings in the back and bottom of the cabinet are provided for ventilation. To ensure reliable operation of the monitor and to protect it from overheating, be sure these openings are not blocked or covered. Do not place the monitor on a bed, sofa, rug, or similar surface. Do not place the monitor near or over a radiator or heat register. Do not place the monitor in a bookcase or cabinet unless proper ventilation is provided. z The monitor should be operated only from the type of power source indicated on the label. If you are not sure of t the type of power supplied to your home, consult your dealer or local power company. ne z The monitor is equipped with a three-pronged grounded plug, a plug with a third (grounding) pin. This plug will fit only into a grounded power outlet as a safety feature. If your outlet does not accommodate the three-wire plug, have an electrician install the correct outlet, or use an adapter to ground the appliance safely. Do not defeat the el. safety purpose of the grounded plug. z Unplug the unit during a lightning storm or when it will not be used for long periods of time. This will protect the w. wj monitor from damage due to power surges. z Do not overload power strips and extension cords. Overloading can result in fire or electric shock. z Never push any object into the slot on the monitor cabinet. It could short circuit parts causing a fire or electric shock. Never spill liquids on the monitor. z Do not attempt to service the monitor yourself; opening or removing covers can expose you to dangerous ww voltages and other hazards. Please refer all servicing to qualified service personnel z To ensure satisfactory operation, use the monitor only with UL listed computers which have appropriate configured receptacles marked between 100 - 240V AC, Min. 5A. :// z The wall socket shall be installed near the equipment and shall be easily accessible. tp Special Notes On LCD Monitors Notes ht The following symptoms are normal with LCD monitor and do not indicate a problem. z Due to the nature of the fluorescent light, the screen may flicker during initial use. Turn off the Power Switch and then turn it on again to make sure the flicker disappears. z You may find slightly uneven brightness on the screen depending on the desktop pattern you use. z The LCD screen has effective pixels of 99.99% or more. It may include blemishes of 0.01% or less such as a missing pixel or a pixel lit all of the time. z Due to the nature of the LCD screen, an afterimage of the previous screen may remain after switching the image, when the same image is displayed for hours. In this case, the screen is recovered slowly by changing the image or turning off the Power Switch for hours. 5 Table Of Contents ………………………………………… 7 Introduction ……………………………………… 7 Electrical Requirements ……………………………………… 8 LCD Monitor General Specification ……………………………………… 9 LCD Panel Specification ……………………………………… 10 Support Timing ……………………………………… 12 Monitor Block Diagram ……………………………………… 13 Main Board Diagram ……………………………………… 14 Software Flow chart ……………………………………… 15 Main Board Layout ……………………………………… 17 ……………………………………… Attaching/Removing the base ……………………………………… Operating Instructions ……………………………………… 21 External Controls ……………………………………… Front Panel Controls ……………………………………… 21 eColor Management (OSD) ……………………………………… 22 ne t Installation 21 ……………………………………… 23 ……………………………………… 26 ……………………………………… 27 ……………………………………… 30 ……………………………………… 36 ……………………………………… 38 Exploded Diagram ……………………………………… 38 Schematic Diagram ……………………………………… 41 How to Adjust a Setting LOGO Machine Disassembly Chapter 4 Troubleshooting Chapter 5 Connector Information Chapter 6 FRU (Field Replacement Unit) List ht tp :// ww Chapter 3 Chapter 7 18 19 el.

How To Optimize The DOS-Mode Plug And Play Plug & Play DDC2B Feature This monitor is equipped with VESA DDC2B capabilities according to the VESA DDC STANDARD. It allows the monitor to inform the host system of its identity and, depending on the level of DDC used, communicate additional ne t information about its display capabilities. The DDC2B is a bi-directional data channel based on the I²C protocol. The host can request EDID information over el. the DDC2B channel. This monitor will appear to be non-functional if there is no video input signal. In order for this monitor to w. wj operate properly, there must be a video input signal. This monitor meets the Green monitor standards as set by the Video Electronics Standards Association (VESA) and/or the United States Environmental Protection Agency (EPA) and The Swedish Confederation Employees (NUTEK). This feature is designed to conserve electrical energy by reducing power consumption when there is no ww video-input signal present. When there is no video input signals this monitor, following a time-out period, will automatically switch to an OFF mode. This reduces the monitor's internal power supply consumption. After the video input signal is restored, full power is restored and the display is automatically redrawn. The appearance is similar to restores the display. :// a "Screen Saver" feature except the display is completely off. Pressing a key on the keyboard, or clicking the mouse tp Using The Right Power Cord The accessory power cord for the Northern American region is the wallet plug with NEMA 5-15 style and is UL listed ht and CSA labeled. The voltage rating for the power cord shall be 125 volts AC.
