S2000 Door open B and Bill validator error

[newkid3]

Hello all, I have a IGT S2000 that I am having a issue with. I have had this machine for at least 6 years. The machine use to work perfectly for years. When i first got this machine I had to replace the coin battery and removed the varta/green battery as suggested to get the machine up and running. I have not been able to use the machine for probably a year. When I went to boot it up I got a Ram error. So I new the coin battery needed to be changed. I put a battery holder and a new CR2032 in it. The battery I took out showed 0v the new battery showed 3.41v. I put the board back in and got the Ram error. So I opened the door and turned the reset key until display said press reset button for 2 or 3 seconds. After that I had to go thru reset cycle again. After that reset the machine started booting up the reels spun and then the 25 cent showed in display for about 2 seconds. Then the display started going back and forth from Open door B and Bill validator error. I did not do anything else to the machine. I would not think it would be a bad board since the battery was removed years ago and the machine worked flawlessly for years. Anyone have any idea what could be the issue. I really dont want to just buy a board unless I know for sure it is bad. The pic of the machine is from a couple years ago working. The pic of the board was before I replaced the battery this time. If you need anymore info or anything let me know.  Thanks

Show us pictures of the messages on the blue VFD display.
You don't actually tell us what message/error the BV has on the display.
Sometimes the messages go away by simply opening and re-closing the door latch fully.

Door open B is the bill validator door switch.  Make sure the BV cash box door is closed tight or bypass the switch.

Thanks for the replies. Here are the pics of the three things it says on the display. It just says Bill validator error no specific thing. I have opened and closed door many times. I can even tell when I just raise the latch and put it back down it tries to reset but goes back to same thing except it will say Closure M also. That is just saying door was opened and closed correct? The bill validator door is bypassed just like it was before I replaced the battery.

Any Door Open is an ERROR message.  The game will not play until it is closed.  Closure is in informational message, simply letting you know that the door that was open is now closed.

What type of bill validator do you have in it?  I'd remove it and see if the machine works without it being installed.

[newkid3]

I don't know what bill validator is in it. I never did have the bill validator working. It is the original validator that was in it in the casino I am sure. I have always used it with quarters. Are you talking about disconnecting the bill validator physically? I can remove it in the morning when I am back with it. I think this board is a 504 REV B. Are there any of these boards out there anymore to buy? Thanks

[Tilt]

Yes, that's what I'm talking about.  If it is a JCM WBA validator there's a handle/release latch on the front of it.  Use that to pull the validator out of it and then power it up and see what happens.

You can still find 504B boards, but they are not as readily available as they used to be and getting pricey too because of that.

I pulled the validator out of it this morning and turned it on and it did the exact same thing. Call attendant / Door open B / Bill validator error. Is there anything else to try? It really does not make sense to me. The last time I had it on about a year ago it worked great for the 8 hours or so I had it on. There has not been a Varta/green battery on it for at least 7 years probably longer. I hate to have to buy a board. I have got into a spot where I need to sell a few of my toys. I have this machine sold if I can get it working. I hate to have to put more money in a board. That would kind of defeat the purpose of selling it some. It does boot up to the point it says 1 CREDIT .25 on the blue display board then it goes directly to the errors. Thanks

[Stayouttadabunker]

After you get to "1 CREDIT .25 on the blue display board then it goes directly to the errors"....do you, at that point, try to close the door?
What happens then?

[newkid3]

Stayouttadabunker, I get that when I turn the machine on and close the door. So the door is already closed when it boots up. I have not tried it leaving the door open. Could that make a difference for some reason?  Thanks

[Stayouttadabunker]

yeah...sometimes the errors are "stacked".
So every time you open and close the door erases one error or more.
I don't know if your BV was dis-abled during the battery problems.
You would need a key chip to get it enabled in the settings I believe.

If it doesn't work, check the wiring to the bill validator door for that error...it will be the light green pair on the BV door.
See if it's wire nutted or twisted together at the end of the two wires or still plugged into a microswitch?

There's also sometimes a cherry switch behind the cashbox.
Pull out the cash box and firmly slide it back in.

If none of these work, then show us a high resolution photo of the MPU board.
Easpecially of where the Varta battery used to be.
We would need to see if the traces got eaten away over time from improper cleaning of previous battery acid.

[newkid3]

Do you want a picture of both sides of the board where the varta battery was?

[Stayouttadabunker]

No...The top component side of the MPU is okay.
Did you try our other suggestions?
It will help us help you get your machine running the way you want.

When posting a photo, make sure one side of the photo (horizontally or vertically) is set to 1000KB or less so it will post on here.
It doesn't matter how big the other side is.
I use windows paint to adjust photo size but there's other ways.

Ok I booted the machine with the door open and all I got was call attendant / door open B. I closed and opened door many times and door open B would not go away. I took cash can out and put it back in and the bill validator error showed back up. I closed and opened door and the bill validator error went away again. At the beginning of this (yesterday) I had opened and closed the door many times before and the bill validator error would not go away. Maybe it is in the order the MPU receives them. With door closed it got bill validator error first then the door open B. Doing the other way it did not receive bill validator error until I removed cash can and put it back. So it was the last one received so it cleared it out first. Where as before the door open B error was last and opening and closing the door would not do anything because it could not clear out open door B to get to bill validator error. Does that make any sense? Here is a pic of the coin box door wires crimped. This is the way they have been since I owned this machine. Here is a pic of the MPU where the Varta battery was. It does look like there is some stuff there. Maybe I did not clean it good or forgot to. If the pic is not good enough let me know.  Thanks

[newkid3]

Here is a pic showing more of the board. If you need a pic of a certain area or something let me know. Do you think this is where the problem is?  Would it be a broken trace? Thanks

Sounds weird but mine was acting strange and to find out it was the power supply. Machine worked great then out of nowhere it started acting weird. New power supply fixed everything. Hope that helps. They will figure it out on this forum.

[newkid3]

Another thing I noticed was when I first turn the machine on the reel lights come on for just a couple seconds and then go off but it goes thru the boot sequence then errors. Are the reel lights suppose to do that and then come back on after complete boot up or after first coin played or something?  Thanks

[lookes]

You have some bad traces that are under the Varta. Looks to be repairable.

[Stayouttadabunker]

Okay....on a plus note. 
The light green wires crimped is good news...that means they're not using the microswitch and are crimped together.
However, look at the photo below...>>>

That hole where the red wire is going through appears to be blackened and shorted out. 
That hole is NOT supposed to be there. 
It appears to be some sort of a home modification using that red wire on the cashbox microswitch going thru the door?

Can you show us what's on the OTHER side of that cashbox door and where that red wire is runnning to?
Your picture taking is excellent!
Member Lookes above is your man on micro trace circuit board repairs! 
You might want to send him your MPU for some quick repairs before the acid destroys your board.

[newkid3]

That is not a hole. It is where that bracket is spot welded on. That was just the other end of the red wire still hooked to the micro switch. The bare end of the wire made it look like it was black stuff on the metal. I guess who ever crimped the wires just bent the wire over that way to keep it out  of the way. I have the equipment to repair the board but I dont know what to really check ect. I have done a bit of componet replacement on PC boards. Like stereo, pinball, arcade  ect. I have worked on a lot of EM arcade stuff. Not saying I could not do it but I would probably need guidance. Thanks
