This is getting frustrating, so i had the 12 error the other day, so ,since i had another motherboard(spare), i replaced the proms and restarted slot it starts but there are no error codes on nothing in any of the coins or pay windows.
Any ideas?
I even tried the set015 in place of the game prom , and restarted still nothing for errors, i was hoping to see the code 61 ,but nothing.

No numbers at all?
Check your chips...any of them upside down?
The notch on the chip must match the markings etched onto the circuit board next to the socket.
You might have the "Folded-Legs-Under-The-Chip" syndrome...  :209-

No numbers at all, it boots up lights up, hear the bill validator go through it motions, and nothing in the displays.
Yes, the notches are in the correct direction, ,matches with the socket.

Check the display harness.
If that doesn't work...wiggle upwards very slightly, the motherboard power connector that comes from the power supply.

Watch the display board...or have someone else watch it for you.
Does wiggling the power Molex make any of the lights come on?

I tried that still no # or cdes display, The display panel lights behind glass as does around the reels, but nothing in numbers in any of the coins in or credits display, i checked all harnesses and the are all snug. not sure what to try next

Just a point of information for you -- I think what you're calling the motherboard is actually the removable MPU board.  The motherboard is the fixed circuit board in the bottom of the machine that the MPU board plugs into (it's located on the back wall of the machine for a slant top or bartop machine). 

The removable board that is mounted in the silver metal tray with the knob is the MPU board.  While in this case I think we knew what you were talking about, it's a good idea to keep the terms separate to make sure everyone is on the same page when troubleshooting your machine.   :214-

As far as your specific situation, when you have the machine on and there's nothing in any of the displays, are the reels "stiff" or are they free-spinning (as they would be with the power off)?

Can you try putting in your original MPU board and chips to see if you still get the 12 error?  If so, your spare MPU board may be bad.

Yor are correct the MPU board, sorry about that
When i power up the reels are stiff, so it looks like power is going there.
I then went back to the original MPU board, and same problem. nothing in the displays as seen in the photo attached

I'd try swapping the chips back to the original board.
Take the battery along...
All you gotta do is heat up the big pads of solder on the flat battery contacts with a soldering pencil.
Make sure you install it with the positive side of the battery the same way as the dead one.

Are the reels spinning up when you turn the machine on?

No, the reels are not spinning up, just a little vibration shake when booting up, but no spin.

The top ( 6 Amp "Quick Blow" ) fuse is burned out.

I checked the fuse and it looks fine, i will go buy a new fuse and confirm
Now this fuse is the one - just below the bill vallidator the top one of the 3 at the front correct
Thanks so much for your help so far
much appreciated

While you're at the store - pick up a multimeter.
It comes handy when checking wiring for continuity and other things such as checking fuses...

Did you place the SSxxxx chip in the reel prom socket and SPxxxx in the game prom socket?

give us a little history of the machine!  did it work ok until the dead battery?  a quick way to determine if the fuses are bad is to undo them one at a time. the bottom one, 115vac, the flou. lamps should go out.  the middle fuse, the reels should move freely, and the 25cent denom lamp should go out. the top fuse, the reels will spin freely.

if all the fuses are good and all the chips are in their right position, and the connector on the motherboard is good, and the machine doesn't work, can you get into the diagnostic mode by pressing the white test button? have you tried pressing the white button on the coin in optic board ,putting a credit on the machine.

Jim

I had built this up from a empty shell, i got everything working perfectly for the past year or so, all was good up to a few days ago.
When i booted it up after is was off for over a month or so, i received the 12 error.
So what i did (since i didnt have a spare battery) but had a spare MPU board , i swapped out both proms. onto the other board and booted up, but no errors or and numbers.
I have since gone back to the original MPU and proms back onto this board.
And now i still do not receive any # or errors.
I even tried to Set015 to reset but still nothing.
 I will try the fuse test later today
Thanks

When I pull out the the top 6A fuse, my reels remain "stiff" but
the reel display windows go out - except for the denom light. 
The symptoms look exactly as he's describing to us.

I find that when I pull out the 8A center fuse -
all the reel display window & denomination lights go out & the reels spin freely.

You can switch the middle fuse to the top position for a few minutes to to see if the display windows come on but
put it back to the middle after checking.

I know he already tried it, but thats pretty much the exact same thing that my s+ did when the power supply harness was giving me issues. It just went completely dead except for the lights inside the machine.

Yeah, but he has power to the fluorescent lighting and motherboard
and his denomination light is lit up...>>>


And his reels are "stiff" in the holding position...>>>


Let's see his report on the fuses to see if they are good or not - esp. the top 6A one.  :89-

Still nothing
Checked the fuses one at a time.
 the bottom one, 115vac, the flou. lamps DID go out.
  the middle fuse, the reels should move freely, and the 25cent denom lamp DID go out.
 the top fuse, the reels will spin freely.
The top fuse , the reels remained tight, also when i put the fuse back in you can hear the sound of power going to the speaker and also the reels do giggle as if power is getting to them.

I also noticed there is NO green light on the back of the coin mechanism
Also when i push the white reset nothing happens

Top fuse removed=reels tight and display windows out but denom light should be on, though you didn't say...>>> good!  :3-
Middle fuse removed=reels free and denom lamp out...>>> good!  :3-
Bottom fuse removed=fluorescent lights out...>>> good!  :3-

Giggly reels when you put back in fuse...>>> good!  :3-
Speaker crackling when you put back in fuse...>>> good!  :3-
Coin Comparator light should be "Off" when the door is open...>>> good!  :3-
Test button in-operational...>>>good!
It's not supposed to work when you have a [62-1] code.  :214-
The "Service Coin" button on the CC will not work as well.


You chip is shot.....maybe...>>> You have NOT told us yet what MPU board you have (10MHz or a 16MHz)
                                                                                                         
                                                                                                          or 

                                                                                     what SS and SP chips you have.  :30-





Remember, the MORE you tell us - the better we can help you.  :89-

I have the 10MHz MPU board
SS 7246
SP1271

RWB/Black Tie

SS7246 is a "Double RW&B" 3 coin game.
The SP1271 will work in a 10MHz MPU board.

Below, Info from the PSR on the SP1271...>>>


Program Summary Report:  S-Plus Stepper Slot Version SP1271

COMPLETE SET OF SLOT GAME CHIPS
Game PROM   Programmable Read-Only Memory.  The game program is stored on this PROM.  The PROM is a 27C512 device, and the label indicates S-PLUS GAME, the version (SP1271), and the game type.
NOTE:  This PROM must be installed on a 10 MHz processor board.

We are down to two things...either your harness on your display panel has a bad wire or the display itself is no good.
These original OEM chips work in the other machine right?
They're not copies and they've worked in the past.
That would rule out bad chips...

unless, you incorrectly installed one of them backwards or tried to remove or install the MPU with the power "On".
Don't be afraid to tell us if that happened.
Believe me - I've fried a few things....lol

Try this DRW&B game chips in the other machine and tell us what happens.
We need to rule out a possible bad board or chips.
Swapping stuff is one way to narrow the problem.

Now if i did  incorrectly install one of them backwards, what have i done?
That is a very good possibility, it wasnt until after i remembered the notch in the end ( i hope i didnt wreck this)
As i only have this one slot, i cant try in another one

no big deal,    order a new set of chips      1 sp chip and 1 ss chip.      no other damage sould have been done.


Jim

So you think i fried them.
Where do you recommend to buy these from
 
I just need to state it is for a 10MHz MPU board
SS 7246
SP1271
 Thank you for your help

Well, we're not sure but the error code [62-1] is certainly telling us so.
Why buy something if you haven't checked?

One way to check is to install them in another known working machine.
You have another machine right?

Take the chips off of that board in there and install these to see if they're any good.
You'd like to see if you get past the [62-1] and light up the display windows on the other machine.

If these chips don't work in that cabinet - then I'd say you can place a WTB (Want To Buy) ad in the Classifieds section of NLG and hopefully someone will spot it and get in touch with you.
All you'd have to say is that you're looking for SS7246 and SP1271.

I really don't think BOTH chips are bad!
It's just possible one of them is bad or you wiring to the display panel or the display panel itself is cooked.
You need to narrow it down first before you go shopping.

Swap the display panel into the known good machine to see if it's the display panel or not.
Swap stuff if you can to check out stuff.
If you have a reader/programmer...tell us the checksum number and we can verify if it's right.
But most people don't have the tools.
You're lucky you have an extra machine to do some swapping to narrow it down.

Your post saying that you could of possibly installed it backwards could be the very reason for the [62-1] error code. That's why Jim thinks it could be fried.
Good thing it's only a chip but not both of them?
Who knows what you did really.
Chips don't cost much anyways.

Bunker you are going to have to put your glasses on. :97-

Ron (r273)

Crap! You're right r273! He's gotta go a'shopping then!  :72-
Ahh...chips aren't much anyways - he will learn to put them in the right way next time... :96-









I gotta go buy some glasses too....lol

OK, I found another set of proms ( I knew i had a spare set somewhere),and put them on my other MPU board
So now when I boot up i get the"61" displayed in the winner paid window
I press and hold the white test button until you hear a "Ding"and the 61 1
I close door completely and turn the jackpot reset key one time
 the 0 coins played and the insert coins alternately go on and off 3 times , then the winner paid goes back to 61
I have tried several times and same result, i have made sure all doors and closed tightly.
Ideas?
Please dont say i am going to need the Set015 prom, as i tried the one i had and i get nothing in the windows(i probably fried it earlier in the week by putting it in wrong)
Some progress anyway

The dreaded 61 loop. You probably need a clear chip now.

So since my original one it probably fried.
i should be shopping for
IGT S+ Ram Clear Eprom Set 15

Since you have a SP1271, I would go for a SET90 instead of the SET15 as it will enable more options on the SP1271 if you should ever want to.

Understand that those are two separate chips -- the SET15 (or SET90) will enable the bill validator.  You'll also want a RAM clear chip to be able to deal with the 61 loop issue.

what are the advantages of the set90 over the set015 ,what more function does it have

The SET090 is one of the latest SET chips that were made for S+ before that platform was killed.
It covers a lot more SP chips than the older SET015.

To further exaplain, some of the options that could be set in self test mode on earlier SP chips require a set chip on later versions. On the SP1271 for example, there is a bill to credit option that first must be enabled with the set chip before you can change it in self test mode. Also if you want to use some of the SAS options or progressive options with the SP1271, you need the proper set chip. A SET015 will enable the BV and set the denomination, but that is all it will do. The PSR for a SP chip will tell you what SET chip(s) are needed.

For the SP1271:

Some SP chips can use multiple SET chips but need a specific one for certain features. For examle for the SP1048:
