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, use 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 the type of power supplied to your home, consult your dealer or local power company. 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 safety purpose of the grounded plug. zUnplug the unit during a lightning storm or when it will not be used for long periods of time. This will protect the 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 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. 3.5A. z The wall socket shall be installed near the equipment and shall be easily accessible. z For use only with the attached power adapter (output 12V DC) which have UL, CSA listed license 5 SPECIAL NOTES ON LCD MONITORS The following symptoms are normal with LCD monitor and do not indicate a problem. NOTES • 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. • You may find slightly uneven brightness on the screen depending on the desktop pattern you use. • 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. • 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. 6 Table of Contents Chapter 1 Monitor Features ----------------------------------------------------------------- 6 Monitor Features --------------------------------------------------------------------------- 8 Factory Preset Timing Table -----------------------------------------------------------10 Block Diagram ------------------------------------------------------------------------------11 Main board Diagram ----------------------------------------------------------------------12 Software Flowchart ----------------------------------------------------------------------- 13 Main board Layout ------------------------------------------------------------------------ 15 Inverter Board Layout ---------------------------------------------------------------------17 Front Bezel ---------------------------------------------------------------------------- ------18 Rear Bezel -----------------------------------------------------------------------------------19 Chapter 2 Operating Instructions ----------------------------------------------------------- 20 External Controls ----------------------------------------------------------------------------20 Front Panel Controls -----------------------------------------------------------------------20 OSD Menu ------------------------------------------------------------------------------------22 Hot-Key Menu --------------------------------------------------------------------------------25 OSD Message --------------------------------------------------------------------------------26 LOGO -------------------------------------------------------------------------------------------27 Chapter 3 Machine Disassembly --------------------------------------------------------------28 Chapter 4 Troubleshooting --------------------------------------------------------------------- 31 Chapter 5 Connector Information ------------------------------------------------------------ 34 Chapter 6 FRU (Field Replacement Unit) List -------------------------------------------- 35 Exploded Diagram ---------------------------------------------------------------------------35 Chapter 7 Schematic Diagram ---------------------------------------------------------------- 40 Analog Input --------------------------------------------------------------------------------- 40 Input -------------------------------------------------------------------------------------------- 41 Scaler TSU16AK ---------------------------------------------------------------------------- 42 Panel Interface ------------------------------------------------------------------------------- 43 MCU -------------------------------------------------------------------------------------------- 44 Appendix Online Support Information ------------------------------------------------------ 45 7 Chapter 1 Monitor Features SAMSUNG Driving system TFT Color LCD Size 43.2cm(17.0") Pixel pitch 0.264mm(H) x 0.264mm(V) Brightness 300cd/m2 (Typical) Contrast 500:1(Typical) Viewable angle 150° (H) 135° (V) Response time 12ms LCD Panel R, G, B Analog Interface Video Input Digital (Dual-Input Model) H-Frequency 30KHz – 80KHz V-Frequency 55-75Hz Display Colors 16.2M Colors Dot Clock 135MHZ Max.
