30 data sheet NCB220E innodisplay.co.ltd 11. application notes inverter connection there are 3 potential issues to consider with inverter connection: z power z on/off z 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/of f pin is not used dpms will not operate. pin 5 should be matched to the in verter specification for the on/off pin. brightness dimming control: NCB220E controller boards are analog dimming control method. and it is important to consider the specifications for the inverter to be used. http://www..net/ datasheet pdf - http://www..net/
31 data sheet NCB220E innodisplay.co.ltd 12. troubleshooting general a general guide to troubleshooting of a flat panel display sy stem, worthy of 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 instru ction 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, fa ilure to provide a signal or incorrect graphic card settings. image position: if it is impossible to position the im age correctly, the image adjustment cont rols will not move the image far enough, then test using another graphics card. this situation can oc cur when a graphic card is not close to standard timing or when something is in the graphics line that may affe ct 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 ev erything 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. http://www..net/ datasheet pdf - http://www..net/
