Thefollowingtableoffersalistofcommonproblemswithprojectorsandhowtotroubleshoot.Iftherecommendedsolutionsfailto
resolveyourproblem,contactyourlocaldealertoarrangeforservicing;donotattempttoservicetheprojectorbyyourself.
Problem Possiblecause Solution
Youcannotturnonthe
projector
1.Theprojectormaybeunplugged
2.ChecktheACPOWERSWITCHontheback
oftheprojectorandseeifitisippedtoON.
3.TheACsocketmaybefaulty
4.Thelenscoverisnotreplacedproperly
1.Plugtheprojector'spowercordintoawall
outlet
2.Flipthepowerswitchto"I".
3.MakesuretheACsocketisworkingproperly.
4.Makesurethelenscoverhasbeenproperly
replaced.
Youcannotturnonthe
projectorafterturningitoff
1.Youwillnotbeabletoturnontheprojector
withintwominutesafteryouhavejustturnedit
off.
Thisfeatureisdesignedtoprotectthelamp.
1.Waitfortheprojectortocooldown
completelybeforestartingitupagain
(theprojector'sSTANDBYindicatorwillturn
blue)
Theremotecontroldoesnot
operatenormally
1.Thebatterymighthaverunout
2.Youmighthaveinsertedthebatteriesinthe
wrongorientations
3.Youmaybeoperatingtheremotecontrol
toofarawayfromtheprojector'sIRsensor
orexceededthemaximumangleofsignal
reception;theremightbeanobstacle
betweentheprojectorandtheremotecontrol
ortheremightbeasourceofintenselight
neartheIRreceiver.
4.Ø3.5mmAwiredremoteconnectormightbe
connectedtotheprojector's3.5mmport.
5.Theremotecontrol'saddressisnotconsistent
withtheprojector'saddress.
1.Replacenewbatteries
2.Makesurethebatteriesareinsertedinthe
rightorientation.
3.Adjustthedistance/anglebetweenthe
projectorandtheremotecontrolandtry
again;ifthereareobstaclesbetweenthe
projectorandtheremoteorsourceofintense
lightneartheIRsensorresolvethese
situationsandtryagain.
4.Removethewiredremotecableor
operatetheprojectorusingwiredremote.
5.PresstheENTERbuttonontheremote
controlfollowedbytheAddressbuttonuntil
thepaneloftheremotecontrolashesonce
(approximately5seconds)andtryagain.
Youareabletoturnonthe
projectorandaccessthe
OSDMenubutnopicture
appears.
1.Theprojectormaynotbeturnedonproperly
oryouhavenotselectedthecorrectinput
source.
2.Youmightnothaveconnectedthesource
devicecorrectlyorthesourcemightnotbe
connectedtotheprojectoratall.
1.Makesuretheprojectoristurnedonproperly
andselectthecorrectinputsource.
2.Checktheconnectionbetweentheprojector
andtheinputdevice.
Youhaveconnectedthe
projectortoaDVDplayer
astheinputsourcebutthe
imageappearsbrokenorsplit
inhalves.
TheDVDplayerisconnectedtotheprojector
throughcomponentcables(RGB-SorRGBHV/
YUV2)andyouhavesetittoprogressivescan.
Disabletheprogressscanningfunctiononthe
DVDplayer.
Thepicturelooksdim
1.Theimagebrightness,contrast,colorandtint
mightneedproperadjustment.
2.Thelampisdueforreplacement.
1.Adjusttheimagebrightness,contrast,color
andtint.
2.Replacetheprojectorlamp.
Theimageistoobrightorthe
brightareasareblurry
Thecontrastmighthavebeensettoohigh. Lowercontrastsettings.
Theimageappearswashed
outorthedarkareasappear
toobright
Theimagebrightnessmighthavebeensettoo
high.
Lowerbrightnesssettings.
Theimageisblurry
1.Thelensmaynotbeinfocus.
2.Thetemperatureorhumidityoftheprojector's
workingenvironmentmayhavechangedin
midoperation(i.e.goingfromcoldtowarm
ordrytohumid),leadingtocondensationof
moistureinsidetheprojector.
1.AdjustLinesfocus.
2.Turnoftheprojectorrstandwaitforthe
moistureintheprojectortoevaporate.
Thecoloroftheimagelooks
pale
Theinputsignaltype(RGB-S/RGBHV/YUV2)
mightnothavebeenconnectedproperly
Checktomakesurethattheconnections
betweentheprojectorandtheinputdeviceare
correct.
Theimageashes
occasionally
1.Thecablesmightnothavebeenproperly
connectedortheinputdeviceitselfmaybe
faulty.
2.Iftheproblempersists,itmayalsomeanthe
lampmightbefaulty.
1.Makesuretheconnectorandtheinput
devicehavebeenproperlyconnected;check
toseeiftheinputdeviceisinnormalworking
order.
2.Replacetheprojectorlamp.
Thecolorsoftheprojected
imageareoutofplace(i.e.
displayingredasblue)
TheG/Y,R/Pr,B/Pbcablesfromtheinputmight
havebeenincorrectlyconnectedtotheinput.
Pleasemakesuretheinputsourcehasbeen
correctlyconnectedtotheprojector.
Thenoisefromthecooling
fansuddenlygrewlouder
Thetemperatureinsidetheprojectormighthave
risen.
Whenthetemperatureinsidetheprojector
rises,thecoolingfanwilloperateatahigher
speedtodischargetheinternalheatmore
rapidly.
TheLEDindicatoronthe
projector’srearpanelis
blinkinginred
Thelamporthecoolingfancouldbefaulty. Refertothedenitionof"Page58:LED
