page 20 of 36 application notes using the controller without buttons attached this is very straightforward by following the steps below : ? firstly setup the controller/display system with the buttons. with controls attached and display system active make any settings for colour and image position as required then switch everything off. ? use a jumper to close jp6 jumper, this will fix the board on. ? refer to inverter specifications for det ails as to fixing brightness to a desired level, this may require a resistor, an open circuit or closed circ uit depending on inverter. inverter connection there are potentially 3 issues to c onsider with inverter connection: ? power ? enable ? brightness please read the following sections for a guide to these issues. inverter power : as per the table for cnb1 pin 1 is ground and pin 2 pr ovides dc12v/ 24v dc . this should be matched with the inverter specification: see table. cnb1 pin description 1 ground 2 +12vdc / 24vdc remark: for higher power inverter, more current (for 12v / 24v) can be taken from cna1 pin 1. maximum current drawn on cna1 pin 1 and cnb1 pin 2 is 3a (24v) / 3a(12v) enable : this is a pin provided on some inverters for on/off function and is used by this panel controller for vesa dpms compliance. if the inverter does not have an enable pin or the enable pin is not used then dpms will not be operational. pin 3 should be matched to the inverters specificati on for the ?enable? or ?disable? pin. cnb1 pin description 3 enable further, jumpers jb2 & jb3 should be set to match the inverter s specification for the enable pi n power and high or low setting: see table. ref purpose note jb2 inverter enable voltage 1-2 h = 3.3v, 2- 3 h = 5v (vcc), open h = open collector jb3 inverter control 1-2 h = on, 2-3 l = on brightness : there are various methods for brightness control and it is impor tant to consider the specific ations for the inverter to be used. generally the situation is: ? brightness can controlled by using a re sistor or vr (variable resistor). ? brightness controlled by adding a circuit such as pwm (pulse width modulation). ? no adjustment of brightness is possible. cnb1 pins 4 & 5 are available for c onnecting to an inverter or circuit where vr control is supported. cnb1 pin description 4 vr wip 5 vr a this can then be matched with function controls (osd switch mount) pins 3 & 4: see cable design below .

page 22 of 36 troubleshooting general a general guide to troubleshooting a flat panel display system it is worth considering the system as separate elements, such as : ? controller (jumpers, pc settings) ? panel (controller, cabling, connection, panel, pc settings) ? backlight (inverter, c abling, backlight tubes) ? cabling ? computer system (display settings, operating system) through step by step cross checking with instruction manuals and a pr ocess 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 just see some image on the display. ? a lack of image is most likely to be caused by incorrect connec tion, lack of power, failure to provide a signal or incorrect graphic card settings. image position: if it is impossible to position the image correctly, ie the image adjustment controls will not move the image far enough, then test using another graphics card. this situation can occur with a cust om graphics card that is not close to standard timings or if something is in the graphics line that may be affecting the signal such as a signal splitter (please note that normally a signa l splitter will not have any adverse effect). image appearance: ? a faulty panel can have blank lines, failed sections, fli ckering or flashing display ? incorrect graphics card refresh rate, resolution or interl aced mode will probably cause the image to be the wrong size, to scroll, flicker badly or possibly even no image. ? incorrect jumper settings on the controlle r may cause everything from total failure to incorrect image. 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. ? for a specific backlight tube check the ac pins or ientation (caution: never reverse any dc power pins). also: ? if adjusting brightness control has no effe ct the chances are that the vr rating or method of adjusting brightness is not compatible or correctly connected to the inverter. ? if system does not power down when there is a loss of signal continued failure: if unit after unit keeps failing c onsider and investigate whether you are short circuiting the equipment or doing something els e seriously wrong. generally after common sense issues hav e been resolved we recommend step by step s ubstitution of known working parts to isolate the problem.

page 33 of 36 appendix v ? auto color gain the auto color gain func tion is supported in the argb mode only and is designed to calibrate the controller to the incoming video signal. in order to calibrate correctly, the display must be displaying an image containing both black and white data (see illustration below) when the function is used. the internal processor of the video contro ller chip will then execute a process to adjust the relative values of the rgb signals to achieve t he best performance. the parameters of the corrected rgb values are then stored in the controller and are unaffected by the reset factory defaults function. warning - if the auto color gain is executed wit hout an appropriate image being displayed, then the process will set incorrect values and the display colo rs will be distorted. if this occurs, then it can either be corrected by performing the process correctly or if this is not possible then the reset color gain function can be used. this function will rese t the stored rgb values to a set of approximate values.
