DIMENSIONS Mounting Hole position will be changed next version. 14.64mm 1.6T Max 3mm 31 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: NCB410 controller boards are analog dimming control method. And it is important to consider the specifications for the inverter to be used. 32 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. 33 APPLICABLE GRAPHIC MODE The microprocessor measures the, H – sync V – sync and polarity for RGB Inputs, and uses this timing information to control all of the display operation to get the proper image on a screen.
