Closure MB won't clear

[cowboygames]

Hi All, I've got a closure MB error on one of my machines and it won"t clear. I've already taken the cashbox door wires and tied them together. When I can get it to just a closure m error it still won't take coins or bills although the VFD display alternates between saying insert token, play 3 coins and closure m restart. I'm using a 1270 board and I've done a full clear and reset. Any ideas? Thanks in advance for the help

 Did you do a I/O test will the optics see a closed door ? Did you try a different board? I had a general reel tilt last week that drove me crazy . it turned out to be a bad board . I thought it was the optics (WRONG) wiring (WRONG)reels (WRONG) it was the main board 

[cowboygames]

My optics are bypassed. Went through the IO tests and the BV door test flashes 0 and 1 constantly. Couldn't find anything that said optics tesy, but maybe I didn't look hard enough because I don't have them. Am I looking at bad MPU or motherboard?

[PLUNGER BOY]

 look under  I/O input test Processor listed as main door should flash 0 and one needs to be interrupted to clear error

[cowboygames]

I did those tests and the main door and BV door tests both show constant 0, when I close each during the tests then they flash 0 and 1 alternately as long as they are closed. I would think that when they are closed then a constant 1 should show in the test

No, because the signal is pulsed.

Guys, correct me if I'm wrong, but doesn't "Closure xxx" mean that the door in question was just closed, and not that it is still being seen as open? I think that perhaps there is another problem preventing the machine from playing.

I think the "closure ..." message(s) are supposed to go away after the first game is played under normal operation.

Rob  I just tried ( 5 )  S 2000  Mine say DOOR OPEN M when I close the door this goes away and the machine boots up. S+ and PE+ you had to play one game for the candle to go out this is not true on a S 2000.  You said you have the optics bypassed, take a look at your cherry switch.

I'm going to try to use a little logic here because I don't know.  When we remove the nicad battery from a 502/504 board and a trace gets damaged in that area you will get a door open error that will not clear.  On your enhanced board it will not work with that battery removed ( I tried )  What IF that battery was dead on your board ??   I don't know the ans. maybe one thing has nothing to do with the other.

David I was typing when you posted, but I think your question got ans.

[cowboygames]

Hey Buzz, that's a good thought and I checked that. Finally got pissed and swapped out the MPU and motherboards back to a 504 and 960 combo. Same crap so I swapped the cabinet and door IO cards with known good ones and that didn't work either The son of a bitch just won't fully reset and clear that last hurdle. VFD still cycles through with PLAY 3 CREDITS, INSERT COIN, CLOSURE M and RESTART. Now, I did remove the printer and BV. Is there some kind of jumper I have to put on the now unused plugs to make this work. Also did a full clear and key on the 504/960 boards when I installed them. I'm not super slot guy, but I don't think I've overlooked anything

Yes, you're right.  "Closure" is NOT an error message.  "Door Open" is.

[cowboygames]

So I don't actually have an error? For whatever reason the machine just won't take coins? I installed and reactivated the BV just to see if it was a comparitor problem and it won't ake bills either. All limits are set for more than ample amounts and if I push the button on the coin optics I get a coin in error message, so the machine is reading the comparitor. Still stumped

[knagl]

A machine showing any combination of "Closure M" or "Closure MB" and/or "Restart" and no other messages should be ready to play.  Are you sure the comparator is good?  You've tested the coin-in optics by pressing the button, but the comparator above the optics could still be dead and rejecting all coins for whatever reason.

[cowboygames]

Just finished changing the comparitor, didn't work. Changed coin optics for good measure, that didn't work either. The machine acts like it's ready to play, just won't take any coins. I've got the denom set for quarters, same as it's always been and the token amount is set for 15 credits per token. It doesn't give a dollar value to them it just wants to know how many credits a token is worth

If his machine is anything like mine, this is not true !

 I have 7 S2000  in the house and every one of them when you close the door any and all info displayed on the VFD about a door being opened, will disappear upon boot up.
Untill the door open display is cleared the machine will not play.

[Buzz]

I have never seen a jumper on a BV or Printer. Turn both off in key menu.

OK when you did a clear/key did the machine recognize the door being closed ? You know press test button for 3 seconds and then close main door. I'm assuming you have a cherry switch in place of door optics, try pushing it in 4 or 5 times. I know a clear should have cleared any errors, but worth a try and doesn't cost anything.

Another train of thought, how about putting this board ( with chips ) into another machine ?

[cowboygames]

Yep, everything is working fine as far as the cherry switch and I've checked the door optic mod wiring like 12 times. Doing the clear/key(twice now with 2 differant board types) hasn't been a problem. In fact, if I leave the machine alone for a minute, it goes into it's attract mode feature. The green light is on on the comparitor when I open the door and the switch on the optics will trigger a coin error. Do I need to maybe just set token value to 0 or 1? I know I had that set to 40 before the clear. I don't know why or how token value could make a differance and token value is the only option under the token setup menu option.

A "Closure" message does not equal a "Door Open" message. 

On the three S2000 machines in my basement, and on every machine I've seen opened and then closed in a casino, the display shows "Door Open" when the door is open (and yes, I agree 100%, the machine won't play), and then they show "Closure" when the door has just been closed until a game has been played.  If your machines don't display a "Closure" message on the VFD, I'd venture to say that you have some odd software in them.

I've got to eat my words a little bit. I just tested 29 more S 2000 and 2 of them will display door Closure  after boot up. Those two both have SG000129 game chips.

Kevin  I have to wonder which one of us have this funky software.  34 out of 36 machines are doing exactly as I posted !!!!!!

Hey! You guys are strayin' off the topic here! I've got a serious emergancy here

[cowboygames]

Anyway, I changed the power supply to and no luck. Only thing I haven't changed is the power distribution/comm board. Belly door switch is bypassed for good measure and I traced the cashbox door wires all the way back to the motherboard and tied them together there. I don't have any lights on the MPU, but I don't on one of my working machines either. Should I try the comm board? Is there a possibility the sb or sg chips took a dump?

[FORDSBS]

I'm no expert like the other guys but I'd check the chips.

I suggested putting that board with eproms into another machine. One way or the other you would know if the files are good or bad.

I got a reel tilt on a machine and the comparitor light stayed on. Also cashed out a machine and turned on the attract feature , it will not go to attract with the door open. Make you think your optic bypass is working.  The coin optic button, I've never had one do anything.

[cowboygames]

With the cherry switch pulled out you fool the machine into thinking the door is closed. If you press the coin optics switch with the door closed you get the coin error. You get nothing if the machine thinks the door is open. I swapped the sb chip with my spare and get the same problem. I don't have a backup set for the sg chips to try and it's my Money Mad Martians game so the board won't work in another game unless it's the same theme. Top box will hold it out. I tried swapping the power distribution box to, no luck.

Kevin  I have to wonder which one of us have this funky software.

We might be talking about a couple of different things, too.  I'm saying that when a machine that is powered on then has its door opened, it displays "Door Open" -- then, when you close it, it displays "Closure M" until a game has been played.  Is that not your experience?

(To be clear, I wasn't talking about immediately after a power-on.  I couldn't tell you what my machines display then off-hand -- I'm talking about when the machine is idle and ready to play, opening the door, then closing it.)

Hey! You guys are strayin' off the topic here! I've got a serious emergancy here

Sorry 'bout that.  I'm trying to make the point that a "Closure" message isn't a tilt of any kind, just a notification.

Doesn't "MB" mean "Middle Belly" door? 
Exactly what is "MB"?
