10. APPLICATIONNOTES

A.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

B.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.Pin5
shouldbematchedtotheinverterspecificationfortheON/OFFpin.

BrightnessDimmingcontrol:Thiscontrollerboardsareanalogdimmingcontrolmethod.Anditisimportantto
considerthespecificationsfortheinvertertobeused.

11. TROUBLESHOOTING

A.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.

B.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.

C.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).

D.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.

E.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.
