A button wire on the door of my S2000 shorted out on the door and I now have no power. The chassis lights, including the door and topper lights all work, but the machine won't power on! I have swapped out the Power Supply and the power distribution module, but still no main power?
Any suggestions?  :99-

assuming you swapped out the parts with known good ones?  if the fluoescent  lamps come on then its safe to say that the +25vdc is working. if the leds on the main board come on when power is applied then the 13 vdc is good, because the +13 vdc is used to produce the VCC which powers the LEDS. so if those two are working, then the power supply is putting out the right voltages to get the board to power up and put something on the display. do the LEDS come on ?  anything on the displays?  its possible that some traces were damaged on the motherboard, the power flow is from the power supply to the mother board and into the main logic board and distributed to all other areas of the machine.  some machines have a power distribution card up in the top box. both voltages are present there.

check these out, that is the main power structure for this machine.

Is there a breaker switch on top of the power supply box for machine protection?
Blown fuse/tripped breaker somewhere maybe in the house panel?  :103-

The fluorescent  lamps come on, the topper lights up and the leds on the topper all work but there is nothing lighting up on the door at all. Nothing works except all the lights, and the 120 volt plug inside the cabinet works also. That's it!
Could it be the power distribution board?

The MPU no leds light up....

if you have a meter then you could check the following: J-13,power connector on the motherboard,(last connector bottom right) pins1=no connection, 2=a grd-black/red, 3=+13vdc-red, 4=+25vdc-orange,5=b grd-black/orange,6=+5vdc-black, 7=a grd-black/red,8=+13vdc,9=+25vdc, 10=b grd-black/orange. either ground can be used to measure the voltage.

to see if the voltage is getting into the MPU, remove board, shroud that encloses the board.(pay attention to this when you remove it ,this helps align the board to mate up with the motherboard) this will expose the connectors that go to the MPU.  on J-1  pin 18A =+25vdc,   J-2 pins 1A and 1B=+13vdc.

if you have these voltages at all these points then you may have fried your board.

I have the enhanced MPU board... That make any difference?
Would it be safe to try my board in a machine with the same game?

can't answer that question, don't have any equipment that has an enhanced board in it.   I don't know if they use the same motherboard?

 

its a BIG TIMES PAY machine. They all use enhaced boards.

That is not true, you can use any S-2000 CPU for Big Times Pay, but if you do have an Enhanced MPU check the 2 small Blue "thing a ma giggers"
on the Backplane (Motherboard)

Hold on, all Big Time Pay machines do not have a enhanced MPU board, ( most do have a enhanced sound board )

Jim they do use a different mother board.

I have a 502 MPU in mine.
I don't think that qualifies as an "Enhanced" MPU board... :72-

What are the beginning numbers for the "enhanced MPU boards" anyways?  :129-
You learn something new everyday here!  :89-

7551270 for MPU  /  S 2000 Enhanced Memory 1   7682810

One quick way to tell if you have a enhanced board is, it has a decent type handle that won't smash your thumb when removing the MPU from the machine !! (damn that hurts )

Thanks Buzz...
I have to see what my other board is tonight.
Do the "Enhanced" MPU's need different motherboards to slide/connect into?

Thanks Buzz...  :293- :284-

OOPs...what happened here? I double-posted? Arghhh! sorry.
moderater...please adjust?  :96-

Yes Sir different Mother boards.

 I guess I can start a big fight by saying from my experence with them, you don't want one.   :79- :79- :79- :79- :79- :79-

   AS PER JIM stated there are fuses on the enhanced motherboard check them

OK, so per Jim, if I didnt have an enhanced MB I could have fried my machine? Why would you NOT want an enhanced MB?
It was just a brief brush of a wire on the door that did this.........

Thank you all for your help, and YES I found a blown fuse after digging through a God awful amount of wires. I got lucky this time, might not the next time, soooooo,
I learned a VERY valuable lesson this time.......... ALWAYS, ALWAYS turn off ALL power and I will disconnect the power cord when doing ANY work inside the cabinet!!

I build computers and they aren't as unforgiving as these things called SLOT MACHINES! :279-
Thanks to EVERYONE for your help. It is VERY MUCH appreciated!

Just to clarify a couple of things slotsx2, a MB (motherboard) in a desktop tower case
will be the large circuit board that has everything plugged into it.
In slot machines, the MB also has everything plugged into it but has
an added MPU ( Main Processing Unit ) circuit board.

This MPU board that slides into large connector headers will contain most of the
stuff you see on regular computer motherboards.
The motherboards in slot machines are also referred to as "Backplane" boards.
Just a little different from home computer terminology...

As far as "Enhanced MPU's"...I think they also slide
into different motherboards/backplane boards.
I'm NOT sure about this though ...
because I only have a couple of knuckle busters... :72-

The 1270 enhanced MPU's have a different motherboard than 501,502, 504 MPU's

Yes they do.....

like this

So...! That's the 2 blue thing-a-ma-jigs asperjim was talkin' 'bout....ahh....

Fuses...Are they like breakers or do you have to replace them if blown?

BUNKER they just like new style car fuses  they blow and you replace them

oh! okay..thanks PB! :3-
Kudos ++ to ya!
I learn something new everyday! :89-

ps
I gave everybody a + karma except Buzz...he has too many already...lol

Now I got my feelings hurt.   :8- :37- :8- :37- :8- :37-

The BIG TIMES is working great, thanks again everyone. BUT.................... while I have your attention, listen to this, LMAO
Last night I was playing my S2000 DOUBLE RED WHITE & BLUE and all of a sudden the reels stopped lighting up. ARGHHHHHHHHHHHH

ALSO, my Bally Alpha Mystic Lamp is acting up. I dont know how many of you have a Bally, but when you turn them on, the reels spin and grunt like a sob...
The reels should NOT GRUNT WHEN YOU PLAY THE MACHINE. While I'm playing my Mystic Lamp, the reels go from a golden silence to a very loud grunt.
It actually sounds like it's going into reel tilt, which it has done numerous times.... WTH is going on here. LOL.

Any suggestions for either problem?

Jim

On the S2000 RW&B, check the connectors on the harness that runs from the
reels to the small reel driver board behind the reel tray on the wall behind the cash box.
Also, check the connectors that run from that small driver to elsewhere.
The receptor pins pins might be getting old and not making good contact
on the male pins in the socket housings. Make sense?
Anyways, It's amazing sometimes how things work so much better
just by unplugging and re-plugging a connector.
I call it "pin fatigue"...lol

Watch out for that little hot bulb back there!
It likes to make you shout "EYE-YA!!" or "Ouch!!"     :72-
( Depends on what your burning skin cells makes you say...)

I'd start a new thread in the Bally section for your other machine...
The Bally guys will have all the answers for you in there!

ps
Remember to give Buzz a + Karma or he starts crying... :96-

Mark, just to clarify, the board mounted to the badk of the machine is the backlight controller. The reel driver board, such as it is, is the motherboard on S2000's. The machine can live without one, but not the other :89-

okay...Thanks cowboy...I knew that small board had something to do with the reel lights...lol
The small board back there would be called the "Backlight Controller" board...okay...I got it!!! thanks!

That's allright Bunker, you laugh about my K's now, but when I get enough of them, I'm selling them on EBay and that's going to be my retirement money !!

Well...If that's the case... then I'm giving you + Karma every day! lol

For those of you wondering....slots2x has his Big Times Pay machine working now...!  :273-
It turns out it was a just a blown fuse on the motherboard. (Those "blue thing-a-ma-jigs")
Uh...me & Buzz we're just shooting the bull..... :72-  :5-
We could probably do the same thing using PM messaging but that just wouldn't be the same right? lol

Sorry, but I have to laugh........ Last post on this thread for me, promise!

I opened up Big Times and Red White & Blue just to see if both reel boards were the same. I took all the reels out of Big Times first, then proceeded to pull the reels out of Red White & Blue.
I have been having trouble with Red White & Blue with very slow spinning reels forever. WELL....., LOL

I proceeded to look at the board on Red White & Blue first. I think I discovered the cause of both problems with RWB ( reels have been spinning very slowly & now the reel lights )

ONE OF THE WIRES WERE JUST HANGING THERE, LOL. I thought to myself, "NO" "Could something so simple have caused both of the problem with RWB?"
Well, after my Big Times problems, I have to say I was hesitant to plug the connector in. After all, look at what I went through just by the slightest brush of a wire on the door of my Big Boy.
Well, I bit the bullet, plugged the connector in, ( Then, while holding my breath, turned on the power )
WOW......... I   HAVE BACKLIT REELS! and the reels spin FASTER .............. LMAO
This came from the person I bought it from this way. Even I couldnt plug A CABLE IN THAT HAS A PRONG TO KEEP IT CONNECTED and not get the prong to hold it in engaged......
AHHHH........

I've aged 3 years in the 3 months I've had slot machines, but at least it's fun, LOL.

Things can only be uphill from here, right? RIGHT? RIGHT!!!!!?

Thanks again everyone!!!!! KUDOS to everyone!!!!!!

Jim

It's fantastically amazing how things can magically work better when they're plugged in.... :96-

If I was a betting man I would bet it was a green wire !!

Actually it was a 4 wire connector. Orange, Black, Black/Red & Black/Orange I believe....
