So.. I happened upon quite a deal on these beasts this wkend.. All was well until..

The Wild Cherry simply needed a new battery.. Simple (so far.. BV needs help but will get to that later)

The Tabasco is a totally different story.

- Once I got her home I fired it up and there was nothing displayed, no reel spin, nothing. Just lights on. I turned it off, removed the MPU and re-installed. Got 'RAM ERROR, Lose data etc', went through the jackpot key, open close door a few times and got it up and running fine. While the wife was playing for a bit it suddenly stopped (no errors, just stopped and went blank). Test button does nothing, nothing showing in the VFD. I can hear a slight change in tone in the speakers (static, off....on...off...) and thats about it. All LEDS on the MPU are on except the red/bottom) I's there anything I can try other then posting a WTB? Or is she fried?

(I did test the Wild Cherry MPU in the machine and it showed the eeprom mismatch? in the display.)

Thanks

Harvey

I'd check out your power supply and make sure it's fully seated and tight.

Jason

I'll give that a shot quick.

Btw, I finally have a machine with SOUND..

Same.. Nothing but that slight change in static, on.. off....

I will have to revisit this in the AM.. I'm waking up everyone with my filthy mouth yelling at the poor machine.. Ha.

.

Try swapping power supply from one to the other and check CMOS battery voltage also

Will do.

2.78 on the battery. I then put the MPU in the other machine and same problems. Nothing but the static noise (on. off. on. off ....)

What if any lights are you getting along the edge of the MPU tray?

All amber LEDS on, green also. The red LED will flash for a split second when just turning on. Then back to nothing..

Think I need a new board.. Have one for sale?? Along with a couple batteries and key/clear chips? Ha

Which board series are you dealing with? 500's or enhanced 1270?

I'm still a noob so unsure. Says 1952-0    P/N 75510502 REV A

That makes it a 502 board. May be a bad board, but I'd try reseating all IC's and replacing the battery first

Ok. Will try that.

Harv,
I noticed you said you have sound now.
If you do end up replacing the board do yourself a favor and get a 504 rev B board.
The rev A board will most likely have issues with severe humm.
Review stickied post on this subject.

Thx. Thats exactly what Roz said.

Now that I jumped a battery on the wild cherry and moved the machine, it is going WILD..  :25-

Turned on, reels spin like normal, then the display flickers saying 'door open m, door open mb, closure m, closure b', Not in that order but randomly flickering different.. Optics?

Any info would be great. I will happily wire the optics to the cherry switch if this is the case..

Thanks again, and again......

What do you mean by "jumped a battery"?

Attached 2 wires to a new battery and soldered them on, keeping the old battery still attached. I do this because I'm still waiting on my key/clear chips that I bought 2 months ago that will never arrive..

Thats why I'm on your site now Roz.. Ha

 

Wow, that's very creative!  :72- Never heard that one!  :3-

Check the door I/O to make sure it's seated good. Turn off the machine first though.

Removed the green battery, checked the I/O and alls well now..  :244-

Btw, My Wild Cherry MPU is a 504 with no sound board. I will swap that out with my Tabasco due to the sound..

THANK YOU ROZ! I will be placing my order shortly..

Woohoo! Glad you got it going!

Here are pictures of the BV. It does nothing when the machine is powered on. It is plugged in as you can kinda see in one of the pictures. I have no clue what the 2 dangling wires are for or where they should be plugged in. Together? They are different sizes.

Also, I did order a new MPU, but does a dead MPU cause a complete blackout? Like, when the machine is powered on, it does absolutely nothing.. If I pull the board out and turn on, it at least tests the display etc like normal. And what do the LEDS on the MPU mean from top to bottom.

Thx

Is this same machine from yesterday (Wild Cherry)? Or Tabasco?

Sounds like a power supply to me. Pull your known good power supply and put it in this machine and see what happens. Either it fixes it or eliminates power supply as culprit.

Roz

Tabasco. I put the (bad) Tabasco board in the Wild Cherry machine and it was the same, dead. I then put the (good) WC board in the Tabasco machine and it fired up fine. Obviously errors showed because of the swap, but it showed me that the power supply was working with one and not the other. Right? 

Yes, I thought it was good board and still completely blacked out. Maybe I'm confused on "complete black out". Does the machine light up at least? Just no BV or other signs of life?

Just for kicks, check the pins on the back of the MPU...

Heres a picture of the mess of wires that connect to the bv and bulb behind. And before this 'blackout' happened with the machine, the BV did cycle like normal. Is there a fuse or fuses somewhere in the machine?

So pull out the BV and power on the machine. We've seen issues that would only occur when the BV was in the machine. If I remember correctly, they were NetPlex or display issues, but worth a try either way.

Sorry for the confusion.. I have posted problems on 2 machines..

The 'blackout refers to the Tabasco. It was working then mid spin just stopped and display went blank. All florescent bulbs stayed on. I just mean the functions 'blacked out'. Kinda like me after a rough night.. ha

All I get now is a on,off,on,etc subtle sound/buzz in the speakers along with the backlit reel lights following that same on,off,on...

Thanks for clarifying! Now, someone's gonna have to back me up (heck, or shoot me down, either way, we need a 2nd opinion) on this, but I think it could still be related to your BV. I remember a post explaining that both the display and the BV are both NetPlex devices and if one fails, it could cause faults/issues with other NetPlex devices.

What does it do when powered on with the BV out?

With it removed it does exactly the same. I also tried it after disconnecting both the bv and printer.

Just seems odd that it was acting this way when I first turned it on when I got it.. Then after getting it up and running it did the same during normal play. Do MPU's act that way? Or could it be a loose wire.. The only thing I did to mess with the machine before it 'blacked out' was screw the candle on because it was dangling.

No bent pins on board either? Sounds similar to symptoms seen with a bad chip or a chip is in backwards, but you said it was working fine at one point.  :103- It's obviously MPU related/driven if it works fine with the other board. I've never seen an MPU do that personally, but it is entirely possible. They ARE the brains of the outfit!

Unplug the input to all your lighting ballasts and see if it helps any

Just tried that. Same issues....

No bent pins.. I was thinking the bad chip thing also. I guess I will know in a few days when I test the new board. Could I pop a certain chip out and turn on to see or is that a bad idea?

Won't run if you remove any chips...it is unlikely a chip WENT bad suddenly. Since you have seen the game play with that MPU and chipset, it sounds like all chips are in order, unless any were removed/reinstalled since then.

It's just gotta be the board then...if it plays fine with a different board in.

You could try turning it on with various periferal devices unplugged each time to see if something is shorted and killing it.

I've had a shorted candle cause all kinds of problems

What devices should I disconnect one by one? I wouldn't want to disconnect something and fry another part. I have tried the BV, printer, and ballasts. I also swapped the I/O's and they work fine. Swap reels? Wish I could post a vid of the situation.

Sounds like you've tried most everything other than maybe the candle. You might also look at unplugging power to the backlight control boardand check for wires shorted together around the button panel

Checked out the candle, tried unplugging all the things mentioned. No luck..

Once the new MPU arrives I will go through and look for shorted wires. Hopefully the board just happen to take a shat and nothing else. We shall see.

Thanks for the help guys! and gals.. If theres anything else to try just let me know.

Harvey

The board left today, so you should see it in 2-3 days...and it must be your lucky day, you were upgraded to a 504B board for free! Thanks to us running out of tested 502s and me biding too lazy to test any more!  :72-

Sweet! I'll take 100 more 502's right now.. Ha

Thanks again Roz!

Thanks for the MPU Roz! Up and running.. One last issue

Now on to the BV issue.. It doesn't do its normal routine when the machine is turned on.. It doesn't light up or anything. I can toggle the switch on the right side to force it to run but once I put the toggle switch back it just sits.

Here is a picture of the BV with the wires I mentioned before disconnected. I did turn the machine off and connect them with no luck.

Any tips? Other then not to eat yellow snow?

Thanks,

HarveZ

Ummm....how about "Plant your corn early"??? That's a good tip!  :89-

I just seen it is an older MEI BV unit. I am not familiar with them at all except for use in Odyssey machines. Hopefully, someone else around here is? We really don't even know if it has the right software for IGT do, since it has never operated for you.

An e it doesn't cycle when the machine is first turned on, I would wonder if it is receiving power? We also need to see if it is in enabled in the menu.

It's enabled.. It is connected and I can make it cycle through by toggling the switch on the right side of the unit.. BUT.. then it just sits, no lights, no nothing..

 Does your other machine BVD unit work ? try swapping it out . Having a working machine to test parts from take a lot of guessing out of the problem .P.B.

Yes. I can give give that a shot..

I haven't swapped the BV's yet seeing they are totally different and I haven't done that before.. But I did try to 'test' the BV in the menu and I get nothing.. It doesn't even give me an option, spin does noting when in that menu. I'm thinking there's no communication between? Ideas? Or just swap?

Thanks

I'm sure you could swap it, then Re-Configure NetPlex Devices in the menu, and the other BV will work, but that really doesn't solve why this MEI isn't working for you...

Are there any identifiers on the MEI? Like Software Version?

To be honest, I've never seen that model of MEI in a pn S2000, but I'm sheltered.... :99-

A chip under the unit says 2.23.. There are also dip switches which I have no clue where they should be.. No luck with searches..

Place another order Roz???? Maybe add that Bulls-eye kit with strips, chips to run on my S2000, and find me a choptop top glass... All for the price of a replacement BV... Cool?, I'll even send you this one for free..

Hahaha..

Wait.. You said re-configure.. Can I try that with this unit? I have no clue if this BV ever worked with the machine from the start.. Just got it (the machine) about 2 orders from you ago..

Here is the manual it will tell you what to do with the switches.

Nice.. Thank you

GOT IT WORKING!!!  :259-'s

I had to change a few dip switches (Thx Proten!) And had to Re-configure it.. (Thx Roz!!)

Thanks to all!  :244-

Now I just have to change the sticky 'O' rings on the cash can (I read a post someplace about that) , and then see what bills it accepts other then $1. (I normally carry only $1000 bills and one $1 so will have to make a run to the bank...)

HarvezZ

Sweet!!! Good job!

Thx.. Now to see if the Jackpot works on this bad boy!!

(p.s. I am interested in that Bulls-eye kit you have. Chat soon!)

Almost have the Jackpot working..Ha

My 1st post...similar situation, looking for some input. My dad and I have several IGT's. S2000 4x Diamond started giving intermitten trouble (door closure M , several others I don't recall, etc). The door optics were bypassed by previous owner years ago & has worked without problem. A week or 2 of intermitten errors we decided lets replace the cr2330 coin battery & go from there. The old battery tested @ 2.78V so felt comfortable having it replaced. Old battery was cr2330 with black ring and very narrow tabs. we replaced with cr2330 yellow ring with same positioned tabs only slightly bigger so we trim the wider tabs down to matching narrow. The other green battery was eliminated and a jumper wire installed years ago.  Re-installed MPU, turned unit on, fluorescents lit up, no displays, all LED's on mpu on, with the red flashing. Checked all connections, inspected for bent pins, etc. Took mpu out of working wild cherry, inserted in Diamond, displays work showing netplex link down, then went into Eprom mismatch. Put the nonworking diamond mpu in wild cherry and again fluorescents come on, but no displays but all LED's on mpu on, with red flashing. Also did this swap with my tabasco with same exact results.  Based on these conditions we believe the problem is isolated to mpu. Just seems strange that we started with a playing, intermitten error unit, decided to replace battery and now have a non working unit. The mpu is a 502A with the 155 game proms. Think it's safe to go down path of defective MPU?...thanks Bill

Are you sure you got the polarity correct on the battery you soldered in?

By polarity do you mean the +/- terminal lineups?  old battery looks like it would have been cr2330/guf...new is cr2330/hfn........dimensions, features, volts, etc are exactly the same except the guf tabs (or legs) .75 wide and new hfn tabs are 1.8 wide and would not fit into holes on mpu, so trimmed (cut) them to size and soldered on in. I don't solder, I have a local TV repair shop do it. battery & install are identical to the other s2000 units we have and appear to be correct. still this lil nagging voice says the only thing that has changed is battery (and it tested low). so how did it go from bad to worse. I was not able to duplicate / find the guf battery online so hfn seemed the way to go. a side of me wants to remove this battery, find the small tabbed cr2330, possibly without the black ring,( which mite be just cr2330/GU   but will need to dig some more to verify), install it, and see what happens. it all just seems too coincidental, but its electronics so...

Pull an old socket of a crappy CPU mother board and just buy cr2330 batteries off the shelf at radio shack

I am not a repair guy, just a guy that has some toys so old crappy mpu boards are not lying around. And I am not sure what you mean by "sockets". The battery does not drop into a holder that is soldered  to the board. The tabs are integrated ( a part of, built onto ) the battery. They are not separable from what I can see. we thought about opening up the mpu tab holes to accept the HFN battery without trimming,  but did not wanna oversize em and potentially damaged the trace lines.

What does your "new" battery test at?

New battery test @ 3.05........I  just tried the mpu again in my good working tabasco. Same old problem. Then I pulled mpu tray out some and slammed it in. Powered it back up. Went thru the testing memory cycle, then showed ram error. (where we had no display any other time, in any of the machines using this mpu  ) This makes me think we had no interface previously because of poor connection / seating. I will take it by dad's in the morning, firmly seat it in and see what we get. If there is display then I'm thinking we just go thru the resets and hopefully homefree.

Lets see what tomorrow brings!  :89-

Meanwhile, where the heck have you been? Just lurking? We could probably use you once in awhile around here!  :89-

-Roslyn

AOK....all systems go......began with a very firm mpu/tray install (a slam actually) the 4x Diamonds powered up & displayed. Had to go thru 15 or 20 resets, power on/offs, test switch hits, but it got a lil further along each time til finally aok..... It had:  main door open, call attendant, eprom mismatch, loss of critical data, candles flashing, Ram errors, reel tilts,MB door open, stacker door open, and on & on........but thru repeated on/offs, resets, tests, etc it got further along or did someting different each time......I think it was just cycling thru recalibrations, etc.......persistance paid off here ...(so far anyway )...time will tell                                   

UPDATE.......four times diamond starting acting up again....erratic errors, tilts, etc........lotta different fooling around, swapping boards, chips, etc (have 4 machines but newbie to attempting repairs & a lotta mistakes made along the way)).........anyway this is where I am at........12 of 2003, four times diamond, 25 cent, with BV, cpu brd is model 1952-0, SG 363 (was 155, broke some pins, read where 363 was better route ), VS 09GX0, SB 100196...........have a tested good replacement cpu, have used clear & key chips 97/17 and 224/31......results are same. I get thru clear & key chip procedure up to point where power game up & should display 7key chip config.....it never shows that. it displays "key chip access failure"........if I hit jackpot reset the display reverts back up a couple steps in reset process where it displays "call attendant/machine type mismatch".............when I go into 4.1.1.1 it shows machine is set to 1 - upright. all I can access is acctg, i/o test & history).............I have no clue where to go from here

Just to eliminate this step, after doing a clear, do you put in the SB chip and power up game before key chip procedure?

Yes....I am using the 14 step ram clear procedure sheets. All is as should be up thru step 11. Step 12 where it should display 7 key Chip Config is whats NOT happening.

Try this using your 224 and 31 chips. Run the full clear using the 224. After you get the two amber lights power the machine down and replace the 224 with the 31. Power the machine back up. After you get your 2 lights power it down again and replace the 31 with your SB chip and power it back up making sure to keep the door open. Closing the door with the Sb chip in after running the keychip will negate the keychip process. Should go to key chip menu. Just out of curiosity, are you using door optics on your machine or have they been bypassed?

Optics have been bypassed. Did try your suggestion. It did force me to close door when resetting ram & eprom errors but once done did come up to 7 key chip config.......didnt have my sheets in front of me but did play around with this a lil....looks like a whole lotta 7.1.... items to go thru.......I have a manual, will have to read some more, cause this whole affair seems like a lotta resets are needed or at least confirmed. almost overwhelming, but will read up and go thru 1 step at a time. Thanks for getting to this point. appreciate it...I'm sure I will be back for more help in next day or two......done for today

You'll get there, one step at a time...

Thanx Cowbpygames. Went in next day, took it 1 step at a time. Completed , no problems, been playing normal for about a week. Thanks Again !!.........now moving on to Slam Dunk s+ that I bought several months ago ( not playing, cheaP $$$ ) .......just replaced mpu ( erratic errors, rusty trace lines, not playing, etc ) and gotta work thru programming this thing & see where I am at on it.......right off the batt no candle lites on ( Except when open door), no errors on display, BV not lit up (but can hear the initial start up gers cycling), no buttons are lit, coin comparitor green lite is NOT on,  coins played flashing "0", reels do go thru initial spin start up cycle, ....hoping just gotta go thru resets / reprogram

After changing the MPU you'll likely need a BV set chip to activate the BV before it'll work on that S+. If you have power related problems look at the plug from the power supply where it goes to the motherboard as bad connections there are a common problem

okay thanks....have a bv set ship so will do that.also since post........tried dropping coins in , they hang up in the coin accept mech, had to remove lower large metal chute cover to reach up in & fish out coins. Now the candle top light stays , chart says its a change door closed. hafta to read up on that.

Sounds like you don't have a sample coin installed in the coin comparator.

S+ the LED on the comparator will not lite up with the main door open. The only way I know to check it is pull if loose from the bracket, let it hang from the wires, close main door and open belly glass door.

On the coin optics board ( green board right below the comparator ) You will see a real small button, press this button a couple of times and with the main door still open press the spin button. The machine should have played one game.

sample coin installed properly. however the comp assy was not snapped into place at top. snapped into place, pressed the comp button, it gave credit, hit spin, played a game .re-powered, closed everything up, machine now plays coins as it should. BV is not lit. not sure how to do the BV chip set but will read up on it. thankscowboy, buzz, & CV

Woohoo!!! Good job!i thought it might be a hardware issue! Cool!  :3- :3- :3-

DBV enable HELP. I went thru the process. When I got to the 9 0 credit window it was already on 9 1. I set the denomination to 25 ( this is a qtr machine) is this correct? Went thru the rest of the process - BV does not work. It will cycle on initial start up but no lites, wont accept bills. Last nite the bv routinely made noises like it was trying to power up while I was playing it. But now it does not.......thinkin maybe I will go thru the  whole process again....UPDATE I have gone thru the process again, exact same results.

If it cycles repeatedly while the game is running correctly otherwise I would look at wire connections and cashbox door switches. Also make sure the transport, head and cash can are all seated and locked in properly. Make sure there are no instructions or dirt hindering any connections or operations

Do you know if your DBV power supply is known to be in good condition?

I have no clue what dbv power supply is and this si a recent purcahse that was not working so I have no clue Rick. I am in process of cleaning machine now. Plugging & unplugging, Inspecting, etc.

Look at reply #23 in this thread.    http://newlifegames.net/nlg/index.php?topic=4226.msg8620#msg8620

The wires that are pluged into the BV on your left side go directly to the BV power supply ( it's only 6 or 8 inchs from the BV )

black plastic mounted on side it looks like. any way to know if good? my s2000 tabasco does not have this box on side

I really hate to be the one to tell you this, but the BV power supply won't be the only difference you will find between a S 2000 and a S+.

yeh I kinda figured, but thot I'd give it  alook. Looks to me like there are 2 separate circuit brds under that cover. The larger one  looks to me like it has several areas that have overheated. Fuse is still ok but i have a feeling this brd isnt. it is dbv-145-ss in this machine. in looking at posts the consensus is junk and go with 200 head & ps. I really dont wanna spend any more on this than I have to as I have other countless projects waiting that will also need $$ spent (Konami racing arcade, Golden Tee golf arcade, pinnacle shuffle alley)..i will look for cheapest route, if I dont like the $$ I will let this machine be a coin only and live with it.
