WMS Jackpot Stampede Model 400 DBV-145-SG resets machine "Bug Fixed"

[corndog]

Hi all,

Newbie, first slot machine, Joey at NLG fixed my first PS problem in about 5 seconds. Continuing on with the final bug.....

Finally got the DBV to  accept the bills after a small cleaning of the optical scanner. (Previously, the DBV would loop for about
30 seconds, than stop, would not accept anything, slot would accept coins, no problem.)

Now, DBV will accept bill, all player panel lights go off, machine re-initializes, lights go back on,  DBV spits bill back out.
Machine will still accept coins, plays normally.

I  have not completely removed the DBV, did remove the side panel, pulled the can( Is that what it is called?) Using the credit card
method found elsewhere on this forum. THANKS!!! Couldn't find what an extraction tool was!! Replaced and reseated. Closed door.

Anyway, I don't want to  rip into this thing and break something else trying to fix something someone out there has
fixed a thousand times.

Thanks in advance,  Happy New Year

What kind of bill are you using as your test ?

The DBV145 accepts bills only 2 ways make sure you are following the template shown on the bill entry.
Secondly the 145 does not accept many of the colored bills. My suggestion would be to use a standard $1.00 bill as your test.

[corndog]

Sorry, should have given more detail. 

Using several different $1.00 bills, inserting as shown on the bill acceptor.

Playing with it a little more, just moving the DBV around or pushing on it makes the system re-initialize so I
think I have a loose connection somewhere.

Thanks,

Kevin

Update....

Removed, inspected, cleaned and reinstalled.  Same original problem.  Any help is appreciated.

Thanks,

Kevin

Did you buy the machine as a Parts Complete machine or was it a fully shopped machine?  Sometimes, when you buy a Parts Complete machine, it doesn't mean that all parts were part of that machine.  It could be that you have incompatible software on the dbv head and thus it's not communicating with the slot properly?

[Jim]

that sidemouted  bill acceptor has two door interupts on it, first is the cash can switch, which is pushed down by the cash can being inserted, and the second is the door switch itself. that switch is mounted above the lock ,when the lock is locked the lock cam engages with the switch and tells the machine it is closed, if the door is seen open by the machine it won't work. my guess is that you have an intermittent door switch connection. you can bypass both and all issues are alot easier. you can even do away with the bill stacker when you bypass its switch.

Jim

[corndog]

Continuing with my saga.....

Yes, the bill acceptor door switch and cash can switch work and are working properly in the slot.

Not sure if the slot was parts complete or fully shopped.

So, thanks to Ben over at Fannini slots, I installed a new DBV-200, no help. same problems.

Slot powers up, no problem, will take coins, no problem.

Insert a bill, ( I have tried several) takes the bill, all panel lights go off, slot resets with 1 bong
lights come back on, bill gets spit out.

I have also reset the RAM with the correct chip after installing new DBV with no help.

Really struggling here, any help is appreciated.

Thanks,

Kevin

Sounds like a power supply issue to me.....

Can you plug the DBV power supply into the wall or another source - that way when you insert a bill its not drawing power from the Slot.

[corndog]

OK...I can try that. I have an ATX supply at home. I take it that it is the 12V supply, black and yellow wires.... Thanks,   Kevin

Most ATX supplies wont "Power Up" without a signal on the +5 Power Good lead.
You would be better off with a 12 volt 3 amp little switcher or wall-wart to test that DBV

[corndog]

Thanks for idea's Kirk and Jay, still no help with the ATX standalone supply.  No change on the bug.  (aware how to short out the ATX power on line)

[Neonkiss]

  (aware how to short out the ATX power on line)

PS On to ground.
Check your ATX supply but it's probably pin 14

[corndog]

Sorry, should have made my self a little clearer, I have the ATX supply working the 12V supply to the DBV

Here is a little video of the bug, every once in a while, I will get the bright flash from a random light on the board,
it isn't always the same one.

Have you tried to clear ram. Also are the wires pluged into the validator or are they plug into a board underneath and the board plugs into the validator.

[corndog]

Hi Paul,  Yes, I cleared the ram  (several posts back), not sure about what you mean by where the plugs are. It is a new validator 200, I have checked the
plugs at the DBV and the backplane for recessed, bent, or broken wires. t

Thanks for your idea's!!!

Still struggling......

Kevin

[paul]

Some machines have a board that plugs into validator and the wires plug into it underneath the validator as to keep the wires away from the reels. Have you checked the transport this is the part behind the validator that stacks the bill then tells the machine the bill has been taken care of. If you open door and pull white cherry switch out it will act like door is closed and you can insert bill and watch it closer and see what happens. I have had a trans port take bill and stack it and give no credits. On the williams DBV all switches should be down and try 1st dip in second bank try it up I cant remember if it is up or down.

[corndog]

Hi Paul,, Thanks for the reply.

DIP switches are set correctly, 1 switch on in second bank. Ben at Fannini slots set them before shipping, I did confirm. Nice suggestion watching the bill from the stacker. So the bill goes past the first micro switch and then stops. never makes it to the actual stacker where it pushes it into the can. I can manually push the micro switch with my finger in the transport and reset the machine, so it tells me that switch is working.

Thanks....

Kevin

[paul]

Keven the bill goes through the head and is read it tells the transport that this is a good bill go ahead and accept it so the transport takes bill and stacks it and gives credits to machine What I am saying is that maybe the transport and validator are not talking to each other. Try to push wires in on validator and hold presure and try bill. Sometimes when you disconect Validator you break a wire and all that is holding is the insulation. If Ben supplied the validator we know it is a good one to me that leaves that problem out. From the time the bill starts in everything has a sequence to complete. There are alot of smarter people out here someone will solve your problem. You will look back and think that was simple      Paul

[corndog]

Continuing my slow painful death...

Played with the wires and plug connections of all three plugs, 12V power, backplane harness, and DBV harness while inserting different bills multiple times.
Also removed reel 3, pulled the DBV plug from the backplane and ohmed out the harness, as well as checked for shorts.

Still failing.

It is wierd that different lights, including the candle light on top of the machine goes very bright each time you insert a bill. It is not the same light everytime.

thanks..

Kevin

[Neonkiss]

Sounds like it may be in the I/O board or the MPU.
I think you have checked the machine thoroughly at this point.
Do you have any spare boards to use for troubleshooting, Or is this your only machine.

[Jim]

does the machine still reset when you push the DBV around( as you stated in your reply #2), maybe you can try and isolate what exactly and what area causes this.

LONG SHOTS= unplug the bill validator lighting ( above the bill acceptor 4 lamps)  the other lamps (payline) and panel switches, see if anything changes.

Very LONG SHOT  maybe at some time during transport if the machine was laid down and coins were in the hopper,perhaps one could have got behind the backplane board and is shorting something out????

Jim

[corndog]

Thanks Jim & Neonkiss,

Physically moving the DBV around has been one of the standard checks now, I can't seem to get that failure again.

I have pulled the I/O board again and did a visual inspection, especially around XU31 & XU33 that the manuals block diagram is
stating is the DBV control modules, they look fine, no bent pins on the backplane.

I don't hav any spare boards that I can try, but I think that is the next step I am going to have to make, and start searching around for a spare I/O board to swap in.

I have been an electronic tech for 29 years but I am a little shy at going after the backplane and removing it for inspection. The machine has been
laid on its back when I first got it, don't know if any coins may have slipped back there. 

I will try the "no lamp test" tonight,  I kinda like that idea!!  Gotta go for those long shots!

Thanks for your ideas...

Kevin

[paul]

Keven one last shot for me open the Mpu door pull switch white cherry switch out turn machine on and see if the lites on I/O board all are on if they are insert bill and watch lites and see if any flash or go out for a short time this will tell you something about the power supply. When you cleared ram did you use the right denomination chip or an all denomination chip          Paul

[corndog]

Great idea, I will try that tonight also....and report back

The wires are there but there is no switch for that card cage door..

I used the .25 cent RAM clear chip.... A couple of times....

Thanks....for staying with me..!!

[Neonkiss]

Corndog,
Just had to send you Karma for keeping with it..
The cherry switch that Paul was speaking of is the one for the main door closed.
If you grab the white plunger and pull it out, that switch will lock in the closed position. Same as if the door was closed. This way you can play your machine with the door open. Then watch the lights he was speaking of on the I/O board and see if they change.
I have a few of these machines myself, and if you run into a jam, I can test your boards in my working machine for you. This way you would be able to isolate the problem to the boards or possibly corrupt data on a game chip and not the machine.

Again thanks for posting back each time and I'm sure you will get that machine running.

PS has the machine worked since it was laid on it's back?
