IGT S+ Spin to Win machine

[therockinelvis]

One more question for tonight. With power on are the reels stiff?   The button for pseudo is just below the cc. Small white button where the harness plugs into the coin optics

[Stayouttadabunker]

The Service Credit button is under the Coin-In optics board that's under the coin comparitor.
It can be white but sometimes it's just a little black plastic nib.
Each press of the Service Credit button adds one credit to the game and ONLY works when the door is in an open state.
In other words, the cabinet receiver optic is NOT seeing the door emitter's optical beam.

You know now really not convinced that I am able to clear the 41 error.  Either turning the key or pushing the button next to power switch will remove the 41, but wouldn't it also change the candle behavior.  If the tilt was reset wouldn't the upper candle go out with the door open? The candles don't go out unless I close the door.   If i re-open the door and press pseudo button, it displays a "0" in coins played and doesn't change anything else and its not long before a 41 error again.  Its like a catch 22.

The 41 error is not clearing, it's just letting you into the menus.  It's getting to the point where machine may need a real clearing with a clear chip or SP or SS chip could be have gone corrupt?

[therockinelvis]

If I am understanding right, you are getting the 14 and 1024 when pressing the test button? And when you close and latch the door, you get blank display? Take a couple more pictures of the inside of the front door from CC and left for edge of door. Then inside machine from reels to the right edge of machine. Stop pressing the test button. It will not clear your error. I would like to see a picture of the error 41 also. So turn off machine then back on and close and latch the door. Remember, we can't see your machine. We rely on you for all info.

[OldGuy]

The original problem was when I turned on the machine it gave the 14 1024 and then the 41.  Now it does it after I push the test button and close the door.  Initially, everything is blank, candles out, and then it does the 14 1024 flash for 3 cycles and then 41.  here is pix of reels, followed by door and finally the 41 error.

[Stayouttadabunker]

It seems to me that every time you close the door, the machine is trying to complete a game, but runs into a reel error.
Furthermore, I don't think your reel strips are on the the reel baskets correctly.

In every photo you've posted thus far, the symbols never line up on the payline or completely off the payline.
Some of your photos are showing the reel strip symbols off kilter....something's not right there.

Do you know how to install reel strips?
The cut-out notches on the reel strips must be place around the reel nibs on the reel baskets.
You can feel for the raised molded nibs on the outside off of each side of the reel baskets with your fingertips.

I do know about the basket notches.  For this particular machine, the strips were installed when I obtained it.  As far as the payline alignment, I've been swapping reels and didn't pay attention if they lined up or not.  The reels are not doing anything, no movement what so ever.  The 41 error is killing everything.  Right now, don't know if its a component on processor board, Bad game chip or Reel chip. All I do know is that I can't get beyond the 41 error.  What are your thoughts on fixing the 41 error?  Swapping reels, reel connectors and taking resistance measurements on R1-R5 have all proven that they are not the problem.  Where do we go from here?  I appreciate all the help.

[Stayouttadabunker]

Okay...we have no idea what you know or are able to do.
I'm only telling ya what I see...and yeah...I give out DETAILED explanations! 
Heck...you'll never know...it may help beginners when this topic comes up in their searches for help?

Anyways, do you have a Known-Good MPU to swap your chips onto to try in this problem cabinet?
We need to narrow down what is wrong with this thing.

The reels are not doing anything, no movement what so ever.  The 41 error is killing everything.  Right now, don't know if its a component on processor board, Bad game chip or Reel chip. All I do know is that I can't get beyond the 41 error.  What are your thoughts on fixing the 41 error? 

If it were in my workroom, I would have it repaired probably in less than a half hour because of all the spare parts I have available.
I would be throwing in known-good MPU with working SP and SS chips to rule out those and so on.
Troubleshooting is much easier if you could post up a short video to some website such as Youtube and gave us the link to it?
I might be able to spot something?
Would you agree with me that the more you tell or show us, the better we can help you?
Right now it's sort of a guessing game trying to figure what you mean by what you see and are telling us.
I really need every little freaking detail like when we asked you to swap reel connectors...I wanna know if the error follow the connectors on the harness or whatever....seems like the reels aren't moving.
We want to help you get your machine running the way it should.

From here, I don't know if it's the reel chips or just an unseen bad ground wire somewhere or pins folded underneath a chip maybe not sitting in the holes of a socket or something...even could be the MPU pins with two of them touching each other and stopping signals from the processor to do anything?
So far what we've tried hasn't been the problem...and that's good too because there are a million little things to check that I do all the time when troubleshooting.
Normal 41 code problems can usually just be something as simple as a loose reelstrip or crooked reel basket not pushed all the way back in and rubbing up ever so slightly against the back of the display panel.

If you hit the Cash Out button, will it knock off the 1024 credits?
Something's making that button flash 3 times then kicking in the error code.
Maybe an oxidized pin on the motherboard Molex connector from the power supply harness?
Do you have a Clear chip and Set015 chip?
Wipe out everything and re-enable the DBV....could be a stuck logic signal too.
By the time you report back on all these little checks and suggestions, someone else will see something we don't see and bingo! They'll have the solution to your problem cabinet!

Do not have any spare parts for this machine.  Would be willing to purchase another processor board if you know someone selling it.  I have posted a short video on youtube showing the sequence that the machine follows.  The only problem with the video is it keeps looping, so keep that in mind.  Here is the URL: https://www.youtube.com/shorts/GaQNLn16vcs Hitting any button while the sequence is happening has no effect on anything.  I do not have a clear chip or a set15 chip.  The DBV doesn't work due to the Power supply that goes with it is bad and have never been able to find one for sale to replace it  I will check both the MPU and power supply connectors for obvious signs of corrosion or burning.  Thanks again for the help

[therockinelvis]

I can honestly say that I have never seen anything like that. Something is shorting out. Was the machine on it's back recently? Like maybe a coin shorting out under the motherboard. Or maybe the power supply. Does your mpu have any acid damage from a leaking battery?

[OldGuy]

To answer all your questions, the answer is No.  Like I said at the beginning, this machine has ran great for the last couple years.  It just came up this way the day I posted on this forum.  Now you know how I feel when you say you've never seen anything like this before.

I would order a Clear and Set Chip. You might not need either but I would get them on order. They are inexpensive so if your paying for shipping for one its probably just as cheap to get both.

While that is in flight - may I suggest you get a wooden or plastic utensil along with a flash light.
Pull the hopper, use the flash light to look under the motherboard (small fixed board) that the MPU plugs into.
Use the non-conductive tool to fish underneath and see if a coin has perhaps gotten in there.

I was also reading through the thread - you indicated you didn't have the pseudo credit button.
Under the coin comparitor is a small square board - that is your coin-in optics.
There is a tiny (and I mean tiny) little button on that optics board that if you push it will give one credit.
You could easily mistake this button for a drop of solder its so small.  *** Just noticed that Mark (Stay out of the bunk) posted pics of what to press *** 
Can you please look for this button and see if you can get a test credit going.

In way of another test. With the door closed - if you turn the jackpot reset key the displays should start showing you a bunch of numbers.
This is statistic mode and it only works with the door closed. When you open and close the door stats mode goes away and you should be back to your error.

Please post what chip numbers are in each Game and Reel - I am possibly thinking one or the other could have gone bad. This usually gives a different set of errors than what you are experiencing but who knows.
When you get the Clear Chip we should run that through your machine and see if the error goes away, but if it reoccurs we might want to swap your game chip out, followed by the reel chip. For now don't go to this expense but lets see what occurs with all of the aforementioned tests.

Did thorough inspection of cabinet including power supply and underneath mother board.  All look visually good, no signs of burning etc.  Pushing psuedo buttons has no effect on anything.  You are correct, with door closed and using jackpot key goes to statistic mode and then cycling door goes back to 41 error.  My game chip is blank, whatever was on it is gone.  The reel chip label is SS4446 Type4 followed by game title then L93-2027.

[jay]

Well the good news is that your machine clearly sees your door as closed otherwise you would not get into statistics mode.

See if this method lets you see your chip numbers.

Tried the method to get game number but I don't get two different numbers flashing in Winner Paid.  The only thing I get (flush Right) is 4 then 4446, the reel prom.  In credits I get 0878.  Does that mean that the game prom is not working?

[therockinelvis]

I think 0878 is the SP chip. You have a type 4 game. Maybe someone can suggest a better SP chip

[jay]

Well, you have just proven that the door optics are fine. You would not have been able to display the real chip numbers if the door thought it was closed you also would not have been able to get into the sadistic‘s menu. Had the machine thought the door was open.

It also looks like your self test button works and you can navigate through the menu so that likely means your SP (game) chip is working. I would really like to see how the machine behaves after a Ram clear.

You might have a bad cmos chip. There is one on the mother board as well as on the MPU or it could be a reel driver chip. Or your reel chip (SS). Until the clear chip is run through I wouldn’t address any of these.

[OldGuy]

Want to thank all that provided feedback to my crazy problem, all was appreciated.  Special thanks to Stayouttadabunker, who took the time and effort to check out my MPU, chips etc and then provide me a replacement MPU.  Machine is back up and running. Again thanks to all

[Stayouttadabunker]

Glad you're happy with our help and your new board!
Your chips turned out to be okay, but running a CLEAR chip or new REEL & GAME chips, wouldn't change the way your board behaved when powered up.
That was crazy seeing the 1st reel roll forward while the other two reels spun the opposite direction when powered up.
Four times it would do that, stop, and then get a [41] error.
At the same time, the zero that was in the Coins Played display window, as well as the lower candle lamp, would flash simultaneously.
Very strange "Boot-up" behavior.
I must conclude that the excessive acidic damage from a previous battery leakage, caused this unusual MPU behavior.
therockinelvis in Reply #30 was heading in the right direction with his "suspicious mind" about battery leakage... lol
I'm glad that your motherboard didn't get damaged.
