  • 1.1. SAFETY PRECAUTIONS

    This monitor is manufactured and tested on a ground principle that a user's safety comes first. However,

    improper use or installation may cause damage to the monitor as well as to the user. Carefully go over the

    following WARNINGS before installing and keep this guide handy.

    WARNINGS:

    This monitor should be operated only at the correct power sources indicated on the label on the rear

    end of the monitor. If you're unsure of the power supply in your residence, consult your local dealer or

    power company.

    Use only the special power adapter that comes with this monitor for power input.

    Do not try to repair the monitor your self as it contains no user-serviceable parts. This monitor should

    only be repaired by a qualified technician.

    Do not remove the monitor cabinet. There is high-voltage parts inside that may cause electric shock to

    human bodies, even when the power cord is unplugged.

    Stop using the monitor if the cabinet is damaged. Have it checked by a service technacian.

    Put your monitor only in a clean, dry environment. If it gets wet, unplug the power cable immediately

    and consult your service technician.

    Always unplug the monitor before cleaning it. Clean the cabinet with a clean, dry cloth. Apply

    non-ammonia based cleaner onto the cloth, not directly onto the glass screen.

    Keep the monitor away from magnetic objects, motors, TV sets, and transformer.

    Do not place heavy objects on the monitor or power cord.

    1.2. PRODUCT SAFETY NOTICE

    Many electrical and mechanical parts in this chassis have special safety visual inspections and the protection

    afforded by them cannot necessarily be obtained by using replacement components rated for higher voltages,

    wattage, etc. Before replacing any of these components read the parts list in this manual carefully. The use

    of substitute replacement parts which do not have the same safety characteristics as specified in the parts list

    may create shock, fire, or other hazards.

    1.3. SERVICE NOTES

    1. When replacing parts or circuit boards, clamp the lead wires around terminals before soldering.

    2. When replacing a high wattage resistor (more than 1W of metal oxide film resistor) in circuit board, keep

    the resistor about 5mm away from circuit board.

    3. Keep wires away from high voltage, high temperature components and sharp edges.

    4. Keep wires in their original position so as to reduce interference.

    5. Usage of this product please refer to also user's manual.

    Control Explanation

    Auto Image Adjust automatically sizes, centers, and fine tunes the video signal to eliminate waviness and distortion.Press the [2] button to obtain a sharper image.NOTE: Auto Image Adjust works with most common video cards. If this function does not work on your LCDdisplay, then lower the video refresh rate to 60 Hz and set the resolution to its pre-set value.

    Contrast adjusts the difference between the image background (black level) and the foreground (white level).Brightness adjusts background black level of the screen image.

    Audio Menu controls are explained below:

    Volume increases the volume, decreases the volume, and mutes the audio.

    Mute temporarily silences audio output.

    Color Adjust provides several color options: preset color temperatures and Custom User Color which allows you to adjust red (R), green (G), and blue (B). The factory setting for this product is 6500K (6500Kelvin).9300K Adds blue to the screen image for cooler white (used in most office settings with fluorescent lighting).6500K Adds red to the screen image for warmer white and richer red. Default setting.5400K Adds green to the screen image for a darker color.Custom User Color Individual adjustments for red, green, and blue.1 To select color (R, G or B) press button [2].2 To adjust selected color, press or .3 When you are finished making all color adjustments, press

    button [1] twice.

  • Information displays the timing mode (video signal input) coming from the graphics card in your computer. See your graphic cards user guide for instructions on changing the resolution and refresh rate (vertical frequency).VESA 1024 x 768 @ 60 Hz (recommended) means that the resolution is 1024 x 768 and the refresh rate is 60 Hertz.

    Manual Image Adjust controls are explained below:

    H. Size (Horizontal Size) adjusts the width of the screen image. NOTE: Vertical size is automatic with your LCD display.

    H./V. Position adjusts horizontal and vertical position of the screen image. You can toggle between Horizontal and Vertical by pressing button [2]. Horizontal moves the screen image to the left or to the right. Vertical moves the screen image up and down.

    Fine Tune sharpens focus by aligning the illuminated text and/or graphic characters.NOTE: Try the Auto Image Adjust (see page 12) before using the Fine Tune control.

    Sharpness adjusts the clarity and focus of the screen image.Setup Menu controls are explained below:

    Language allows you to choose the language used in the menus and control screens.

    Exception: This control does not effect changes made with the Custom User Color control.

    Control Explanation

    OSD Timeout sets the length of time an on-screen display screen is displayed. For example, with a 15 second setting, if a control is not pushed within 15 seconds, the display screen disappears.

    OSD Background allows you to turn the On-Screen-Display background on or off.

  • 4.1 Inverter Board Circuit

    The diagram of inverter board circuit is shown in Appendix (PWB-0538). The inverter supplies power for

    backlight for the LCD panel.

    4.2 Power supply Board Circuit

    Please refer to power Schematic sheet in Appendix. The 12Vdc from adaptor output is fed into J800 as

    power regulation of U801 (AO4403) input power and inverter main power on pin 1 of CN830. The U801 can

    provide two independent power sources: a) The 5Vdc will be for main board power. ; b) The another 10.5Vdc

    will output as audio power at when audio jet is inserted.

    4.3 Scaling controller Board Circuit

    The Scaling IC U005 is to convert the input signal from VGA, SXGA and UXGA to a SXGA resolution that

    panel can acknowledge.

    The scaling IC of MRT MASCOT V2 is a highly integrated System-on-a- Chip with very powerful functions,

    including integrated 8 bit triple-channel ADC/PLL, programmable OnPanel timing controller, embedded

    microcontroller with parallel ROM interface, OSD engine, sRGB compliance, and PWM back light intensity

    control.

    The Scaling IC features an integrated timing controller (TCON) that connects directly to commercially

    available row and column drivers. All TCON signals OCLK, ECK, ORGB, ERGB, OSP, ESP, OPOL, OINV,

    EINV on pin 68 to pin 79 of U005 have programmable drive strengths and can be disabled to control Panel.

    The flash memory chip of U001 contains codes via parallel data bus interface to communicate

    with Scaling IC U005.

    The DDC memory chip of U004 stores DDC data and the NVRAM chip stores timings and setting data.

    Since the NVRAM has to get series number information data from DDC chip, both their SDA and SCL 2

    the electrical switching of U009 is isolated and controlled by scaling IC pin GPIO7.

    4.4 Audio Circuit

    The audio Right/Left channels are fed into pin 6 /8 of sound AMP U701 (AN7522) while Audio plug is

    inserted on J701 jack. The sound output amplitude will depend on this bias voltage on pin 9 of U701, which

    is always controlled by Q702. When mute is activated, the Q703 will be forced to saturation to block sound

    output. When standby is activated, the sound outputs of U701 will drive speakers via CN701 connecter.
