I just got two S-2000's and neither was parts complete.
I know have a known good CPU with chips and all other wiring and components now attached.
I power up the machine and get all amber, red and green leds flash for a half second and then go out. When this happens the fan in the top box attempts to spin, but then stops.
It looks like the machine gets start up voltage for the half second and then shuts down. It will do this ever 5 second or so but not come up. I have replaced the power supply with 4 other power supplies with the same result. The only difference is with one of the other power supplies, the re-start cycle with the leds is much faster almost every second.
Could I have 4 bad power supplies? or is there something else I should check first?
Also if testing the power supplies with a DVM where should I test and is it like a computer power supply where it need a load before powering up?
That's what it appears to be doing. It powers up for the half second and then powers back down.

Do all three fluorescent bulbs blink when it tries to power on?

No, I assume the power on - off cycle happens too fast to have a florescent light react that quick?

I have seen a bad ballast cause the on/off cycle when a know good board works.

Sounds like you've got a short bringing the power supply down. Start by unplugging stuff on the motherboard and all the lighting. Then plug back in till it repeats the origional problem

Thanks Cowboy....   :244- :244-
That did it. It was J19 Speaker, Main Door LED
I then plugged the J19 back into the backplane and disconnected the door display, Door I/O, power to the VFD and the VFD.
Powered on the machine and it went back to the flash start-up. So it must be in the wiring to the door?

OK. I traced the wiring a little further and found where two wires White/Yellow and Green/Yellow go into the top box and to the Power distribution board in the center of the top box. With this one un-plugged and J 19 back on the motherboard, it boots up.

Now what is J5 on the Power Distribution board P/N 75802940

The top three 2-pin headers on the PDB are J5, J6, and J7 are 25Vdc outputs -
basically for fluorescent lighting.
The wire colors on that row are usually orange and black.

 THIS BOARD ?

That's the one. Unplug the top box florescent from that and probably the candle also. I've had shorted candle wiring take a game down on me before. As mentioned earlier, probably the ballast on that top box florescent, but could be either one. For that matter, it could be your amp board too.

Here's the schematics of the board Neon...>>>


wow plunger! Your wiring has plastic markers on them! Cool!  :89-

Thanks everyone.
Pictures ARE worth a thousand words.
I was able to see from Cowboys pictures that someone had some wiring mixed up.
It should be correct now as everything appears to plugged in correctly and the machine powers up.
I got the Call Attendant on the display, So I installed a Key 31 chip.
It would not light both upper amber led, only the second one and the VFD reads "Display's NETPLEX link is down"

So what's not connected now?

First thing to check is that the power supply is fully seated and tight along with all other boards, including cabinet and door IO boards

OK, Maybe I don't have all the wiring that I need.  :103-
I have a connection to Netplex in, but no connections on the three Nexplex out connectors.
Where should the Netplex out be connected to?

what board are you talking about ? I can send pic if needed    .If talking about the distribution board  usually just  for toppers / sound amp / and power for progressive display

I added pics above of my machine. I moved the speaker wires out of the way and tried to keep the other organized so you could see where they are going.

 the red and black wires( plug) on the right side and the left side (plug ) are power. cant see right side plug in pic

Thanks, Ya I get the power in and power out.
Then you have the Nexplex in, but I don't have any Netplex out.
Could I be missing a wire harness for something on Netplex out that is causing my error of "Display's NETPLEX link is down" on the VFD?

Netplex link is down  on the vfd is usually a bad power supply or partial power   the netplex out on the distribution board is not needed  it is just a jumper. do you have 12v and 24v at distribution board at power in

Yes, I have the 13VDC and the 24VDC
Now remember the error of netplex down is only displayed when I attempt to use a Key 31 chip.
Top amber light never comes on and the second amber led illuminates.

Otherwise with the game chip installed and the door closed I get the Call Attendant displayed.

Neon,
Cowboy is right about the Power distribution board in the topbox -
it's just for candles, fluorescents and other stuff.
I really has nothing to do with your blue VFD display on the door.

There's a ribbon cable on the back of the VFD on the right near the door hinge...
is it pushed into the VFD solid?
It sounds like that ribbon cable is partially out and off some of the pins inside the connector?

Would you have a different keychip to try?

Chip not installed will cause the nexplex link error.

haha! Yes! The error should go away when the SB chip is back in the MPU.  :72-

Robert I'm tired and am not going to read all this thread but, you install the key 31 power up, vfd will display net plex down, (EVERY TIME ) remove the key 31 and install the base chip it should now go into key menu.


Mark  You beat me to it !!

By just about ten minutes man!  :72-

Robert I need to add to this.  After you remove the key chip and power up with the base chip, to machine will try to boot and then that damn horn will start beeping. Just turn the jack pot key 4 or 5 times, the vfd will tell you to press the test button for 3 seconds, ( press it for 6 seconds, 3 is never long enough )  vfd will now tell you to close the main door, you then will get Call Attendant open the door and the horn will; start again, turn the key 4 or 5 times again.  It may tell you to press the test button again or the machine will boot up. ( you just never know ) 

When you use  key to enable key chip menu
re-installing the base chip does not cause any errors or siren sound normally unless there was a system or other error even before the key chip was used.
 
it will boot right into key chip menu as long the door is open if the door is closed then you get key menu faillure.
I have never had a key chip cause the siren sound to occur.

Foster When I get some machines in the first thing I do is clear the machine with a clear 97, then I use a Key 31,  When I power up with the base chip back in the machine I will get the horn at least once, sometimes two times. If the horn sounds off more that two times, something is wrong with the machine and must be fixed before you can continue with the key menu. If you think this to not be true, why don't you take a little ride to the West Coast I've got about 75 machines that need to be shopped and you can see for yourself.

Now why are we splitting hairs as to whether the horn sounds off or not ?? The point I was trying to make is, if Neno hears the horn he won't think he blew up his machine !!

Buzz, don't get mad but Foster said he doesn't get the horn when his keychip is in there...uh...not the base chip.
I think he misunderstood what you meant?
I get the horn when I put back in the base chip too...
I keep my hand on the reset key every time so I can shut it off immediately.

I'm still wondering if his VFD problem is because of a loose ribbon cable on the back of the VFD display?
I've had a bad VFD display, got the Netplex errors, swapped it out and problems went away!

OK, Just got home and tried a few of the suggestions.
a) I remember reading that a bad power supply can cause the Netplex error from this post
       http://newlifegames.net/nlg/index.php?action=printpage;topic=1885.0
    I tried my other power supplies and get the same result so not sure if the power supply is the issue or if I have 4 bad power supplies.
b) When powering up the VFD reads PASSES SELF TEST (or something like that) So all the connectors are on the VFD and it is receiving power.
c) The error of NETPLEX DOWN is only seen with the Key 31 chip installed. The general lighting illuminates and the WBA cycles. I DO NOT get the two      upper amber lights on. I only get the second from the top amber light (this must be a clue)
d) My key 31 chip is installed on a IT chips 27C240-100 that were purchased off ebay here, http://www.ebay.com/itm/320738638179?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 they were to be comparable to the 27C4002. Not sure if this is an issue.

Until the machine completes the Key 31 set-up and I receive two amber light, I'm sure it won't continue the set-up. Actually I tried it with the base chip installed and got nothing. Just the VFD with the Call Attendant showing and no response from the key switch or buttons.

Anyway have to run back to work tonight so I'll keep trying the suggestions. Keep them coming I'm sure someone will get it.

I would try burning your KC31 to a different chip...preferably the ones we usually use for s2000's.
That would at least eliminate that question especially, if the amber lights come on with a different chip device.

 Do you have any other s2000 machines ? If so swap boards with  the games on them and just turn the reset key  to reset and push button on cpu and see if game plays  this could narrow this down ?

Neon  I think your in better shape than you think.  First off all the key chip does is open the door for key config.  All key set up is done after the key chip is removed and the base chip is installed. I know it doesn't look like it but "Call Attendant" is a good sign. When you see Call Attendant open the main door ( this is where the horn comes into play ) turn the jack pot key 4 or 5 times while watching the VFD at some point it will say "press test button for 3 seconds, then it will change to close main door. after closing the door the machine will do it's thing and you will get a "Call Attendant" again.Open the door and Turn the key 4 or 5 times. you might have to press the test button and close the door again and you might not, you just never know.

I don't know about the LEDs Who is to say maybe one of them is burned out. I would think if your getting "Net plex down" it's ready for the key menu.  :103- :103-

Robert I wouldn't bet the farm on a S + but for sure the BV will cycle even if NO MPU is installed on a S 2000. I think S+ is the same.

Bet the farm.  The DBV on an S+ is powered by its own power supply which gets power as soon as the S+ is turned on, regardless of anything else.  It will cycle, even if the game isn't working (so long as the machine is plugged in and the S+ power supply isn't fried, of course).

OK, here is the latest up-date.
Turns out I had two issues going on. The first was the SB file for the I Dream of Jeannine was bad. No matter what chip I would burn it to my back-up file was bad. So I lost the original and my back up. I did find a 3CM and it work fine after I corrected the second issue, which was the CPU board was bad.

Now I have a working 3CM with 2CM R/T glass. If anyone has the 3CM R/T glass send me a PM.
I also posted in the WTB for the matching DVS card.
I installed the backlit reels and they look great.

Neon  The list I have calls for a DSV00018  I Dream of Jennie   Sorry I don't have one to send you.

WOW YOU GUYS ARE GREAT  :244- :244- :244- :244- :131- :3- :131-

Thanks to Jim (Midwest Slots) and Bunker for their recommendations and support in that IDOJ is a clone of Double Diamond.  :89- :89-
The new file works perfect and the payouts are correct.
I sure hope the DVS simm for IDOJ will work with the Double Diamond chip.


Thanks again guys, now go find me the simm card.  :200-

I'll betcha there's a guy named Jim that has one...!
I know where there's a whole crapload of IDOJ toppers too!
Check this out!... >>>

OK, OK, You talked me into it.
Send me a IDOJ topper for the R/T also.
