1. Turnoffandunplugthe game.

If your game is NOT an eVo, skip to Step 5.

2. Unlockandopenthe cashtowersection.

3. Inthe cashtowersectiondisconnect the

4-pinconnectorfromtheLEDboard (see

Figure 1) and carefully route the wires

backthroughtheaccessholebelowthe

motherboard (see Figure 2). It may be

easier to open the CPU section while

doing this, but make sure to support the

CPU section as the game will become

top-heavywhenboth sections areopen.

4. Closeand lock thecashtowersection.

5. Unlockand open theCPUsection.

OVERVIEW: Replacingthe Power Supply consists of disconnecting all wires connected to the

power supply, removing the old power supply, installing the new power supply, adding 2 new

harnessestothis power supply, then refastening all oftheconnectionsin the unit.The following

sectionswill walk youthrough both theremovalof theoldpower supply andthe installationof the

Power Supply Installation

NOTE: The replacement power supply may

beslightlysmaller in size than thepowersup-

ply that was in your unit. Because of this, ad-

ditional foam tape may need to be added to

thepowersupply mounting bracket. Ifthereis

already a double layer of foam tape on the

bracket, you do not need to install additional

tape. If there is only a single layer of tape,

and the new power supply isn’t seated cor-

rectly, follow the guide in Figure 6 below to

properly install the provided tape on top of

theexistingtape.

FOAM TAPE

1. Installthenew powersupplyby placing it

inthe unitandsecuring itwiththe screws

andbracketthat held the oldpowersup-

ply(seeFigure5). Besure thatthe power

supplyis installedwiththeIEC connector

onthetop-left.

2. Replacethetwist clamparoundthelarger

set of wires that will run to the

motherboardandI/Oboard,thenreinstall

thestandoff(see Figure5).

3. Attach the 20-pin connector on the pro-

vided DC jumper cable (EC0355) to the

20-pinmatingconnectorcomingfromthe

powersupply (see Figure 7).

showninFigure 7. For more detail,follow the

stepsbelow:

•Connectthe20-pinpowersupplyconnec-

tor tothemotherboard(seeFigure4).

•Connectthe appropriate4-pinconnector

to the centronics power connector (see

Figure3).

•Connect the mating 4-pin connector to

J6ontheI/Oboard(seeFigure 4).

•Reconnectthe harddrivepower connec-

tor (see Figure 2) using the appropriate

4-pinconnector.

•FOReVoONLY:Locate 4-pinconnector

ontheDCjumpercablethatconnectswith

the LED board and route this down to-

ward the access hole below the

motherboard(see Figure 2).

4. Replace the motherboard by sliding it

under the clamps on the left side of the

game,then liningupthe two screwholes

onthe rightsideof theboardwith thetwo

standoffs in the game. Replace the 2

screwsthat fastentheboard tothegame

(see Figure 2). Make sure no wires are

theprovided touchscreen & LCD power

cable (SB0538) to the remaining 4-pin

connector coming from the new power

supply(referto Figure 8).

Continueconnectingthetouchscreen&LCD

detailfollow thestepsbelow:

•Connect the mating 2-pin connector to

theupperfan,whichislocated nextto the

powersupply.

•Connectthemating2-pinconnectortothe

lowerfan.

•Connectthemating4-pinconnectortothe

LCDpowerconnector (see Figure 3).

6. Reconnect the IEC connector to the

powersupply (see Figure 2).

7. Tiewrapany cables as necessary.

8. If your system is NOT an eVo, you have

completedthepowersupplyreplacement.

Closeand lock the CPUsection,making

sureno wires interfere whenthebezelis

closed.Ifyour system ISan eVo, goon

to Step 9.
