Handling
SMDresistorsandcapacitorsarewidelyusedintheCyrusrangeofproducts.Whenhandling
SMDcomponents,certainprecautionsshouldbeobserved‐
HandlingSMDresistorsandcapacitors
AlwaysstoreSMDcomponentsintheiroriginalpackagingorinacooldryenvironment.
AlwayshandleSMDresistorsandcapacitorswithtweezersoravacuumpencil.
NeverhandleSMDresistorsandcapacitorswithfingers.
HoldtheSMDcomponentbythebody,notbytheends.
DonotuseSMDresistorsorcapacitorsiftheendsaredirtyordiscoloured.
DonotuseSMDresistorsorcapacitorsiftheyhavebeendroppedonthefloor‐ theymay
beinternallydamaged.
Alwaysusereplacementcomponentsofthecorrectsizeandshape.SMDcomponentsare
availableinmanydifferentpackages.Wherepossible,orderoriginalpartsfromCyrus.
HandlingSMDICs
Alwaysstorethesecomponentsintheiroriginalpackagingorinacooldryenvironment.
AlwayshandleSMDtransistorsandICswithtweezersoravacuumpencil.
NeverhandleSMDtransistorsandICswithfingers.
Ensurethattheconnectionpinsoflargermulti‐pinICsarenotdeformedordamaged
beforefitting.

Avoidusingsharp,pointedprobesdirectlyonthecomponentendcaps.
MeasurevoltagesfromthePCBpadnexttothecomponent.
Staticprecautions
SMDcomponents,particularlyICs,maybedamagedbythestaticlevelspresentinthe
workshop.Damagecausedbystaticmaynotimmediatelycausecomponentfailurebutcould
causepartialdamageandapossiblefailureinthefuture.ObservingthesesimpleSMD
precautionswillavoidproductfailuresrelatedtostaticdamage‐
Alwayswearagroundedwristbandwhenreplacinganyelectroniccomponents.
Alwaysstorecomponentsintheiroriginalpackagingorconductiveplasticbags.
Neverstorecomponentsinplastictraysorbagswithoutprotection.

Neverre‐useoldSMDcomponentsafterde‐soldering!
Alwaysapplysolderheatdirectlytothecontactarea.Avoidover‐heatingadjacent
components.
AlwaysrepairSMDPCBswiththecorrecttools.SMDcomponentscanonlybereplacedwith
ahotairpencilorsolderingirondesignedforSMDcomponents,preferablywith
temperaturecontrol.
Keepthesolderingtemperatureaslowaspossible.370ºCisrecommendedforLeadfree
SMDrework.MostSMDcomponentswillwithstand370ºCfor5to10seconds

PCBassemblies
ThefollowingisabriefdescriptionoftheinternalPCBsfoundintheCDt.
TheservoPCBismounteddirectlyontotheCDmechanism,thisincludestheCDloadermotor
andsleddrivers,theservodriverandCDdecoder.
ThemainPCBismountedinthebaseofthechassisandcontainsthepowersupplies,optical
andcoaxialSPDIFoutputandtheuserinterfacemicrocontroller.

Discreading/decodermoduleandservoPCB
Thediscreadinglaserpickupismountedinamotordrivenslotloader,whichreceivesits
operatingcommandsviatheservoPCB.

TheheartoftheservoPCBistheCDdecoderIntegratedCircuitIC401.Thisiscontrolledby
softwarerunningonthemainboardmicrocontrollerIC701viaanI2CBus.
Themicrocontrollersendshighlevelcommands(e.g.ReadTOC,Playtrack1)totheservoPCB
viaacommunicationbus.DiscloadingiscontrolledbythemicrocontrollerontheservoPCB.

WhenadiscisinsertedintotheplayerthefirstthingthatneedstohappenisthattheTableof
Contents(TOC)ofthediscisread.Thisinformationcontainsthestartandendlocationofeach
trackonthediscfordiscnavigationpurposes.

InordertoreadtheTOCthelaserisswitchedonbythedecoderIC,andafocusrampis
initiated.Iffocusisfoundthenthediscmotorisswitchedonforashorttime,thenthePLLis
switchedonandthediscisacceleratedtofullspeed.Oncethespeedhadbeenachievedand
thePLLislockedontothedata,theradialloopisswitchedonandthesubcodewillberead
fromthediscandfedtothedecoder.

Thefocusandradialpositionsofthelaserspotarecontrolledbythedecoderbylookingatthe
diodesignalscomingfromtheopticalpickup(OPU).TheseareD1,D2,D3andD4forfocus,R1
andR2forradial.TheerrorsignalfromthesediodesisusedtogenerateaPDMsignal.This
signalisthenfilteredwithalowpassfilterandamplifiedbythemotordriver(BA5984FP)to
movetheactuators.

PowerforthelaserdiodeissupplieddirectlyfromthedecoderICwhichmonitorslaseroutput
andadjuststhepoweraccordingly.

Thereisasinglesystemclockontheservoboard,8.4672MHz.Thisisself‐generatedbythe
decoderIC.

Thereare2mainpowersuppliestotheservoboard,+5V_CDforthesignalprocessing
electronicsand+5V_MOTORtoIC402supplyingmotorandsledpower.The+5V_CDsupplyis
subregulatedto+3V3andsub‐sub‐regulatedto+1.8Von‐boardforthedecoderandother
electronics.

Microprocessorcontrolsystem
SystemcontrolisprovidedbymicrocontrollerIC701onthemainPCB.Themicrocontroller
acceptsexternalusercommands(IRhandset,frontpanelkeysandMC‐BUSloop)and
translatesthemintoinstructionsthatoperatetheCDmechanism,viacommandssenttothe
servoPCB.
ThemicrocontrollercommunicateswiththedecoderontheservoPCBviatheCD_CLand
CD_DAlines.
DigitalOutputs
ThedigitalaudiodatafromtheservoPCBisfedtothemainPCBviacableassemblyCON701.
ThedataisthenbufferedbyIC601andIC604.TheSPDIFdataisfedtotheopticaloutput
(TOTX401)andtotheRCAcoaxialoutput(viadigitaltransformerL402).

Powersupplies
TheinternalregulatedpowersuppliesfortheCDtarederivedfromaswitchingpowersupply
onthemainPCB.Thishastwoseparateoutputs,+5Vand+10V.

CAUTION!LIVEMAINSVOLTAGES!
WhenundertakinganyrepairworkontheCDplayer,engineersshouldnotethattheplayer
includesaswitchingpowersupplyconnecteddirectlytolivemainsandotherhighvoltages,
locatedonthemainPCB.CapacitorsinthepowersupplywillretainveryhighDCvoltages,even
whendisconnectedfromthemains.Exerciseextremecarewhenremovingorhandlingthe
mainPCB.
Powersupplyrepair
Ifapowersupplyfaultissuspected,checkthevoltageofthe5Vand10Vpowersuppliesonthe
mainPCB.ThesecanbefoundattheSMDelectrolyticcapacitorsC506andC507.Ifeitheror
bothofthesepowersuppliesismissing,theremaybeapowersupplyfaultorashort‐circuitto
thepowersupplyinquestion.
TheprimarysideofthepowersupplycanonlybetestedwithanisolatedDVMwhenthemain
PCBisinstalledcorrectlyinthechassis.NeverconnectpowertothemainPCBwhenithasbeen
removedfromthechassisoruseanygroundedtestequipmentsuchasoscilloscopestocheck
forprimaryfaults.
Initially,checktheDCsupplyvoltageacrossthe'+'and'‐'pinsofD501.Thevoltagefoundwill
dependonthemainsvoltage,butwillbebetween300‐350V.Ifthisvoltageisnotpresent,
disconnectmainspowerandchecktheminiaturefuseFS801.IfthefuseisOK,removethePCB
andchecktheprimarycomponentswithaDVMresistancemeter.
IftheDCsupplyvoltageispresentandthepowersupplyisnotrunning,checkthevoltage
betweenpins1and8ofIC501.Thisisabout0.9Vinnormaloperation.Ifthisvoltageislow,
checkR501.Checkalsothebiassupplybetweenpins2and8ofIC501.Thisshouldbearound
6V,butwillonlybepresentiftheswitchingsupplyisswitchingcorrectly.Ifthesupplyisnot
switching,suspectaproblemwithIC501orTX501.TX501canbecheckedwithaDVMsetfor
resistance.
Thesecondarysuppliesaresimplerectifiedsupplies.The'FEEDBACK'lineprovidesclose
regulationforthe+5Vsupplywhilethe+10Vsupplymayvaryalittleinvoltage.Ifthe+5V
supplyisnotaccuratelyset,thisismostlikelyacomponentfaultinIC502orthenetworkof
componentsaroundit.
Discwillnotread
Ifthediscwillnotread,checktoseeifthediscisrotating.Ifthediscisrotatingthenitmeans
thatthelaserhasfocussedonthedisc,thereforeallpowersuppliesareok.Ifthediscdoesnot
rotatethencheckthepowersuppliestotheservoPCBatpins+5V_MOTORand+5V_CDon
connectorCON405oftheservoPCB.Ifthepowersuppliesareworkingcorrectly,removethe
loaderandsubstitutethelaserpickupwithanewreplacementunit.Ifthediscwillstillnot
read,substitutewithanewservoPCB.
CAUTION!WhendisconnectingtheflexfoilcablefromthelaserpickuptotheservoPCB,always
ensurethatstaticprecautionsaretakenwithagroundedstaticmatandwrist‐strapasthelaser
pickupcaneasilybedamagedbyrelativelylowlevelsofstatic.Whenthediscreading
mechanismorlaserpickupareremovedfromthechassis,itispreferabletofitaflexfoiland
useametalpapercliporsimilartobridgeallopenconnectionsasstaticprotectionwhen
handlingthepickup.

TheMC‐BUSsystem
MC‐BUSisasystemwhichprovidescommunicationbetweenthecontrolsystemsofanumberof
Cyrusproducts.Thecommunicationtakestheformofaserialdatastreamwhichissentfroma
'master'productandreceivedandrepeatedby'slave'products.Thedataisthuspassedfromone
producttoanotheraroundaloop.Themasterproductshouldthenreceivethemessageback
whichconfirmsthatloopconnectionshavebeencorrectlymade.TheCDplayerisa'slave'product
andlistensfor'CD'commandsfromthemasterproductintheloop(usuallyanamplifieror
surrounddecoder).

MC‐BUSinternalsignalrouting
MC‐BUScontrolisprovidedbythesystemmicrocontrollerIC701.Thesignalsarebufferedintoand
outofthisICasshowninthediagram,TheresistorbiasattheMC‐BUSinputensuresthattheline
idleshigh(+5V)ifnoMC‐BUSconnectionismadetoanotherproduct.

MC‐BUSsystemtests
TheMC‐BUSsystemcanbetestedbyconnectingtheCDplayerintoaknownworkingCyrus
system.NotethatMC‐BUSmustbeconnectedasaclosedloopasshowninthediagrambelow.It
isalsoimportanttoconnecttheaudiosignalcablesbetweencomponentstoprovideanadequate
groundreturnpathfortheMC‐BUSsignals.Switchonthepowertothesystemandsetall
componentstoStandby.SelectingtheCDinputontheamplifierorswitchingonasurround
decoderwillnowactivatetheCDplayer.WhentheamplifierissettoStandby,allother
componentsconnectedtotheMC‐BUSloopwillalsosettoStandby.
