Data Sheet NCB400U4 ASSEMBLY NOTES This controller is designed for monitors and custom display projects using 1280x768 or 1600x1200, resolution TFT LCD panels with a VGA, SVGA, XGA, WXGA, SXGA, WSXGA and UXGA signal input. The following provides some guidelines for installation and preparation of a finished display solution. Preparation: Before proceeding it is important to familiarize yourself with the parts making up the system and the various connectors, mounting holes and general layout of the controller. As much as possible connectors have been labeled. Guides to connectors and mounting holes are shown in the following relevant sections.
1. LCD Panel: This controller has TTL and LVDS interface logic on the Board for different kind of TFT LCD panel. For the other type of LCD interface like Panel Link interface and etc, this board can accommodate a daughter board instead of on-board LCD interface. Due to the different signal timing and electrical characteristics from each LCD panel manufacturer, for selecting LCD interface type and resolution, put jumper marked J5 on the right position following LCD panel specification. For selecting DC power level, put jumper marked J19 on the right position. Supplied power level depends on LCD panel specification. 2. Controller: Handle the controller with care as static charge may damage electronic components, Make sure correct jumper and switches settings to match the target LCD panel 3. LCD connector board: Different makers and models of LCD panel require different panel signal connectors and different pin assignments. 4. LCD signal cables: In order provide a clean signal it is recommended that LCD signal cables should not longer than 30cm. If loose wire cabling is utilized these can be a made into a harness with cable ties. Care should be taken when you place the cables to avoid signal interface. Additionally it may necessary in some systems to add ferrite cores to the cables to minimize signal noise. 5. Inverter: This will be required for the backlight of an LCD, some LCD panel have an inverter built in. As LCD panels may have 1 or more backlight tubes and the power requirements for different panel backlights may vary it is important to match the inverter in order to obtain optimum performance. See application notes for more information on connection. 6. Inverter cable: Different inverter models require different cables and different pin assignment. Make sure the correct cable pin out to match the inverter. Unsuitable cable pins out may damage the inverter. 7. AV cable: Standard composite or S-video cables can be used. Reasonable quality cables should be used to avoid image quality degradation. 8. OSD Button: See Operational Function section.

Data Sheet NCB400U4 APPLICATION NOTES USING THE CONTROLLER WITHOUT BOTTONS ATTACHED This is very straightforward: Firstly setup the controller/display system with the buttons. With the attached controllers and display system active make any settings for color, contrast and image position as required then switch everything off. Remove the control switches, the 7-way cable. Refer to inverter specifications for details as to fixing brightness to a desired level, this may require a resistor, an open circuit or closed circuit depending on inverter INVERTER CONNECTION There are 3 potential issues to consider with inverter connection: Power ON/OFF Brightness (DIM-ADJ) Inverter power: This should be matched with the inverter specification. Inverter ON/OFF: This is a pin provided on some inverter for ON/OFF function and is used by this panel controller for VESA DPMS compliance. If the inverter does not have on/off pin or the on/off pin is not used DPMS will not operate. Pin 5 should be matched to the inverter specification for the ON/OFF pin.
Brightness Dimming control: NCB400 controller boards are analog dimming control method. And it is important to consider the specifications for the inverter to be used.

Data Sheet NCB400U4 TROUBLESHOOTING General A general guide to troubleshooting of a flat panel display system it worth considering the system as separate elements, such as: Controller (jumpers, PC settings) Panel (controller, cabling, connection, panel, PC settings) Backlight (inverter, cabling, connection, panel, Pc settings) Cabling Computer system (display settings, operating system) Through checking the system step by step cross with instruction manuals and a process of elimination to isolate the problem it is usually possible to clearly identify the problem area. No image: If the panel backlight is not working it may still be possible to see just some image. A lack of image is most likely to be caused by incorrect connection, lack of power, failure to provide a signal or incorrect graphic card settings. Image position: If it is impossible to position the image correctly, the image adjustment controls will not move the image far enough, then test using another graphics card. This situation can occur when a graphic card is not close to standard timing or when something is in the graphics line that may affect the signal such as a signal splitter (please note that normally a signal splitter will not have any adverse effect). Image appearance: A faulty panel can have blank lines, failed sections, flickering or flashing display. Incorrect graphic card refresh rate, resolution or interlaced mode will probably cause the image to be the wrong size, to scroll to, flicker badly or possibly even no image. Incorrect jumper settings on the controller may cause everything from incorrect image viewing to total failure. CAUTION: Do not set the panel power input incorrectly. Sparkling on the display: faulty panel signal cable. Backlight: Items to check include: Power input, controls, inverter and Tubes generally in this order. If half the screen is dimmer than the other half: Check cabling for the inverter. Also: If system does not power down when there is a loss of signal.
