40 kordis media co.,ltd. data sheet NCB410U2 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 se ttings 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 dimmi ng control method. and it is important to consider the specifications for the inverter to be used. www..net www..net
41 kordis media co.,ltd. data sheet NCB410U2 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 ins truction 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 t he image correctly, the image adjustment controls will not move the image far enough, then test using another graphics card. this si tuation can occur when a graphic card is not close to standard timing or when something is in the graphi cs line that may affect the signal such as a signal splitter (please note that normally a si gnal 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 c ause everything from incorrect image viewing to total failure. caution: do not set the panel power input incorrectly. ? sparkling on the display: f aulty 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. www..net www..net
