Hello, I have a Sigma Treasure Tunnel slot machine model sg-150b plus that has stopped working and can use some help.The game turned on fine but on the display it said "now self testing wait for a while" and never changed from there. I tried pulling all the plugs and chips from the main board and re-seated them. I put the machine back on and now the display says "game data mismatch please check it". In the manual it says that message means denomination gal eprom missing. It says as a fix I should replace gal Eprom (ic59). The chip was put back in correctly so I'm not sure why that message is coming up now or what to do next. Any good advice will be very appreciated.

Yes I do. I've tried turning it and nothing happens. I also tried to do a ram reset by keeping the key turned, holding the test button inside while turning the power on to the machine and still nothing happens. Should I try something else with it?

Post close-up photo's of you MPU board.. :211- :211-

Here's 3 let me know if you need others. Thanks.

Here's the third.

Things look good....Have you checked for bent pins?..Also, try using the reset key when you get the "Mismatch Error"...Where does it stand now when it tries to boot?

There's no bent pins I checked again. The reset key doesn't do anything and when the machine boots up it still says game data mismatch please check it. It doesn't change from there no mater what I try. Turning the key or doing a ram reset doesn't change anything.

the weak part on the sigma sg's is the power supply,  check the voltages -there are taps on the front of the board. -the important one is 5v, it can be calibrated inside the power supply.

 I believe I see 3 taps directly to the left of the larger chips in the front of my board. If those are the ones your talking about then they all have exactly 5 volts. Are those the correct ones that I'm supposed to be checking?

This is a picture of the taps that I checked.

there should be 4 taps, one is a ground,  should have 5v, 12v and either -12 or 24v (i don't remember off hand -prob 24v to drive the reels)

how did the machine first malfunction? was it ever working?  -did you check the voltage on the coin cell soldered on the board? -should be at least 2.9volts

no no no absolutely do not mess with those jumpers, you can toast chips.

look closely on the front of the board, towards the left, you will find the taps -i think they are designated with (TP)

Found them. Yeah I think tp1 is the ground. Ground to tp2 is 5.1v, ground to tp3 is 12.7v, and ground to tp4 is 25.7v.  The machine was working then stopped during play. I couldn't get it to work so I did a ram reset and this was the result.

I'd check the coin cell on the board but have no idea what it is. Sorry. Can you tell me where it is?

I have a 3.6v lithium battery that is soldered on the board which is putting out 3.6v. Not sure if that's what your talking about or not.

Are the wires hooked up to the reset key switch?...If you have a continuity checker, check that the switch is working...It should be N/O and when you turn it N/C...

The wires are hooked up and yes the switch works. I checked it with continuity.

Can you post a video of the machine booting up and showing the error code...

I'm having difficulty posting the video. When you turn it on all 3 reels spin 1 full revolution then stop and then in the display it states Game data mismatch please check it. In the other 2 displays that are for the winner paid and credits screens, that's just blank nothing comes up there now. If you need the video still please send me an email address that i can send it to. Thanks.

You could upload your video on youtube, and put it in your post.  :89-

I think your battery is ok for now. I would try doing the hard clear at least three times by holding the test button while holding the reset key and powering on all at the same time like you did before. Sometimes Sigmas need to be cleared several times to get a full clear. Also, you MUST have the machine on a good surge protector. Sigmas are very sensitive to surges. When you do the hard clear you must hold the reset key and the test button for 30 seconds, the reels should spin and the door display should say "ram change turn the reset key two times" when the clear has completed properely. Try the clear a few times and report back to us. -Koni

Also, on switch 2, dip no. 7 can be turned ON so the machine will not be looking for the condition of the battery.
They will work just fine without one. a couple of my boards have no batteries at all.

I tried turning on that battery switch and did the hard reset 3 more times while holding it for close to a minute each time but it still says game data mismatch please check it. I have a new gal eprom chip coming. I should have it tomorrow. I'll replace it and let you know how I make out.

Ok, I got the new gal chip and put it in. I now get this message that comes up. I tried doing the 3 long factory resets and it didn't help. Any other ideas? Thanks.

Try re-installing you old GAL chip and see if you get the same error, then put back the new one...
Let us know what happens...

Back to the original message when I switch chips.

Sounds like you might have toasted the MPU board and/or the game chips...There is a MPU board on ebay you might want to try and get...Here is the link...

http://www.ebay.com/itm/SIGMA-SLOT-MACHINE-SG-150-PLUS-CPU-PCB-MOTHER-BOARD-/110973306535?pt=LH_DefaultDomain_0&hash=item19d68646a7 (http://www.ebay.com/itm/SIGMA-SLOT-MACHINE-SG-150-PLUS-CPU-PCB-MOTHER-BOARD-/110973306535?pt=LH_DefaultDomain_0&hash=item19d68646a7)

If your gonna keep your machine, it is a good idea anyway to have...

Thanks for the link. Do I try to get new chips too or just try the board first? Also what's with the gal chip I replaced? Can you tell if the original is fried?

I would say try the board first....As far as the GAL chip, use the new one...Most likely it is the good one...

Just bought the board on ebay. Am I going to have to do anything to the board other then swapping the chips? In the description of the new board the guy mentioned something about a cd with files on it?

Mostly check the jumpers and switch conf.  The CD might have the .bin files for your game...Let's see when you get it...

That's correct, its supposed to have the bin files for treasure tunnel. 6 files total. How will I know if I need to use the cd? Just set the switches, jumpers and new chips, plug the board in and see if it works?

Good luck with your board,
Hope that fixes your problem   :133-
Just be careful transferring your chips.   :89-

I got my new board and put it in. It seemed like it started to work. The reels spun it said loading game and then this came up. Not sure what it means cause all the doors are closed.

I found that there is a switch that senses when the side door is closed. I can't access it right to check it with continuity to make sure its working correctly. I was wondering if there's a way the sensor can be bypassed by programming it electronically? I'm thinking that maybe the switch was always defective but the old board was programmed to bypass it which is why I never got this error code before but get it now since there's a new board in it now that recognises that the switch isn't working. Is this possible?

Do you have a bill acceptor?...If so, do you have the cash can?...Do you hear the bill acceptor cycling?
Turn off the power and set sw#1 post 10 to off...That disables the bill acceptor and should tell the machine you don't have one and should get rid of the error code  if I remember right...

I do have a bill acceptor and cash can. They are both in the machine but it does not cycle . I will try the switch thing in 5 hours when I'm done work. Thanks.

I turned the switch off and you were right. It got rid of the error code and the machine works now. Your really good at this. Lol. What can be wrong with the bill acceptor? I'd like that to work also. Thanks.

OK...That is good...Now it sounds like the cash can door.  There should be a white reed switch and a white magnet...The reed switch is on the left side of the cash can box assy. and the magnet should be on the cash door...Or they both there?...Maybe take photo's of those areas so I can see more...

This is the door and inside where the cash box goes. I'll post some more.

Here's some more. I don't see a sensor or switch.

There is a type of switch with 2 wires connected to it that you can see from inside the machine. It has a small metal piece that pushes up and clicks when I turn the key to lock the door of the cash box.

Sorry, I was thinking you had a SG300...I guess you have a SG-150...Try tracing the wires back to the MPU board and make sure the switch makes and brakes all the way back...I believe there is a 2 pin connector in-between the switch and the MPU...If that is not connected, you will get this error...

Also there should be a circuit board that attaches to the BV head...Do you have that board?...I believe the door close switches attach to that and then run back to the MPU board via a ribbon cable...

Is that it?

No...It attaches to the Bill validator head...

That one?

That is it...Looks like everything is wired...Lets recap, you installed the cash can all the way-closed the door and locked it-Now turn sw1 post 10 back on and see what happens...Does the bill acceptor cycle?...Do you still get the error?

That's all correct. I never had a problem like this one before. It's just started since I replaced that main board. I was thinking that maybe the cash box door switch has always been bad but there's a way to program the board to bypass the switch which may have been done by the company that I purchased it from and when I installed the new board I have the problem now because its not bypassed on the new board. Is something like that possible? I was ordered to go to dinner by the wife so I'll check it again with the number 10 switch back the way it was in a couple hours. Thanks so much for all your help.

So what your saying is that the BV worked before and now with the new board it does not?...I was told I need to make dinner, so I will off line for awhile or until tomorrow...Let me know what you find out...

Yes that's correct. I never had a problem with the bill acceptor until now with the new board. I did just put switch 10 back on and started it up. The game loaded right up with no error codes however the bill acceptor didn't cycle or make any noise at all. It doesn't take bills either.

I tested the voltage to the bill validator and there isn't any. I checked the black and the orange wire that goes to it looking for 12v but there wasn't any. I then did a ram reset to try that and now once it loads its back to the error code that says, "bill vali door open".

Look at CN12 on the attached file...

I checked out the file but not too sure what I'm looking at? Lol

that is the pin outs of cn12 on the MPU...Do you have a cable hooked up at that position?...Photo of the MPU installed with cabling if possible...CN12 should be as your looking at the board on the left side towards the front of the machine...Sometime people hook that cable to the wrong spot...

I think its hooked up right.

Not sure if this matters but I traced the 2 wires that connect to the cash box switch and the purple one is cut right under the bill acceptor. Could this be the problem? It's had to have always been like that since I've had the game.

Actually I think the wires from the switch went here and the switch was just bypassed here at this plug.

It looks like one of the ribbon cables is not seated all the way in the socket on the CPU board.

I checked the ribbon cables and they all seem to be seated all the way down. This door status code on the front of the machine has 3 blocks lit up next to the "p" which is saying that the cash cassette door is open, the cash cassette is removed and the bill acceptor door. None of which are open or missing. What would make the machine think all those sensors are tripped when they're not?

Where is the cable plugged into CN24 going?...Is the Cable in CN12 going to the BV?....

The cable that's plugged into cn24 goes to the bill validator. There's nothing plugged into cn12.

Ok so I have no clue how it got there but your right again. The cable was in the wrong spot. I transferred them over from the old board to the new one exactly how they were but I guess the cable was unplugged and put in the wrong spot a couple years ago which is the last time this thing worked. I think your going to have to send me a bill for this since I seem to have another problem though. When I put a dollar in the bill validator it takes it but it doesn't register the credits and gets jammed. I have to take the cash box out and then grab the bill along the top and pull it out the rest of the way. It doesn't put the bill into the cash box. Yes I'm sure the cash box is in facing the correct way when I put it in. Any other amazing suggestions for this one?

Great news so far...You can try taping all the levers the cash box engages when installed and try run a bill without the cash box...If it does except and give credits, your cash box is bad...If it does not, then try cleaning the BV...I believe there are some threads on how to clean them...Let me know

I didn't find a helpful thread for cleaning the BV but I took it out and blew some compressed air through it and checked all the belts, etc. It still doesn't work. I think its something else. When I put a dollar in with the cash box out and the side door open I can see that the BV takes the dollar good and strong but only pulls it in far enough so it comes about 2" into the cash box compartment and then just stops. The motor doesn't continue to pull it the whole way through. Is there any kind of programming or resetting that has to be done since I changed the denom chip and main board?

No there is no programming...that is what the denom. chip does...What denom. did you get?...Also do you know the version software in the BV?

I was told to replace the denom chip before the board incase that was the only problem. The chip in the picture installed on the board is the new one I got that's in the machine right now and the original chip is the one in the other picture. I just noticed that they are different numbers. Is there a problem with that?

I have no clue about what software version it has. As I'm sure you realized by now, I'm not very knowledgeable about these things.

From the picture they look to be the same numbers...What do you see that I can't make out?...Sorry but wife says time to quit for now...Did you try putting back in your old chip?

The original chip says GA01-25C and the new one says GAM1U-25C.

Did you try swapping chips?

Yeah, when I do that I get the original error message that says, "game data mismatch please check it."

You get that error if you only swap the GAL chip or are you swapping all your original chips?

Just the gal chip. I only have the 6 larger original chips. I never bought new ones of those.

OK...Well at this point I am at a loss...I have not heard of the denom. chip to cause that problem...On that note, I have not seen a GAM1 denom chip so I am not sure what that means...the 01 & 02 are for different jurisdictions...Since you said that if you turn off sw1 post 10, the game works (but without the BV), then I would try to order a new GAL chip that is a 01...02's restrict programing...Where did you get the chip?

I got it from John at Rudysdeals.com. What do I tell him? The new chip might be defective?

He is a great guy....I have dealt with him for a long time now...Ask him if he knows what a GAM1 chip is for and that it seems to be not working...See if he has a GA01 to replace it...

Ok. I tried calling him but there's no answer. I guess he's closed weekends. I'll try monday and let you know how I make out. Thanks.

I heard back from them about the chip and they said the chip they gave me came right off another treasure tunnel board and that they have a treasure tunnel machine with the same chip in that one as well. Not sure exactly what to do.

I am not sure either...I believe you have a SG145 bill validator head and transport...It has been awhile since I worked on a SG150...If you have the 145, you should be able to pull out he head and open up the cover to see if what eprom version you have...What bill were you trying to insert in the BV?

I tried putting a one dollar bill in. Does this picture answer your question about what type of BV it is?

The BV is a 200 which is good, but the bad news is it is the wrong ID...You need ID003 not ID44...I think I have a eprom with ID003...I will look this weekend...Happy Turkey day!

Thanks, I'm not sure I know exactly what you mean or how I have  the wrong eprom but as long as I'm left thinking that you might know what's wrong with this thing then I will sleep very good tonight. Thanks again and you also have a wonderful Turkey day.

If you remove the DB200 and look at the bottom of it you should see a eprom with a tag...Maybe photo that also...Sometimes the label is different then the actual eprom installed...

Here's a picture of the chip.

That is the eprom...To bad there is no label...I will try to see if I have one this weekend...

Could that chip have gotten damaged the same time the denom chip and board got damaged?  I never had a problem with this BV before. It always worked great with no problems. Also my new board  needs a new battery. The original board had a 3.6v battery that looks like a small AA battery and the new board I got has a 3.0 v round, flat battery. Do you know which kind I should get? I think its weird how both boards are the same but have different size batteries. Does it matter?

You do not need the battery...Just turn off sw2 post 7...The only way I can think of that both the MPU and the BV might have gotten damaged is by hooking up the power cable wrong...

The power cable being wrong never would have happened but I never had it plugged in a surge protector so I was thinking maybe a power surge?

Not the power from your plug that goes into the wall..The multi-pin connector that feeds from the powersupply to the MPU board...It is the big one on the backside of the board and on the right

I know the plug your talking about. I know it wouldn't have been plugged in  half turned  or anything like  that but I do know there is a plug a few inches back on the same  ribbon cable  where it plugs into the board that is the same size plug as the one on the end of the cable that I may have plugged in there. Not sure what that's there for.It's been a long time .

Wait niever mind. The cable all the way to the right. I'm positive I never touched that one except when I put the new board in.

Also I forgot that the DBV-200 uses a ID11/15 protocol not ID003 (that is for the 145 head) for Sigmas...I will still look to see if I have that...
Jimmy

I think I found one...I PM you!

Hey I got the chip and put it in and now the light in the front of the BV that says insert bills is flashing and it won't pull in the bills when I try to put them in. Do you know what could cause this? Could I have put the chip in backwards and needs to be turned halfway or something?

   When the jackpot key is activated, it turns on a light in the Meter Window.  If you see this light, then the key is working.
