i keep getting coin in jam error and cant figure it out. i have tried a few diffrent boards it still does it. changed the power supply. when you push the button on the board it will bring up accounting but you cant do any thing with it. and it lights up 8 in the win metter. any suggestions?
thanks
keith

Here is a thread from a week or ten days ago, I don't think the machine ever did get fixed.   http://newlifegames.net/nlg/index.php?topic=15154.0

i read that thread i will try a few of the things that was talked about and see what happens
thanks for the reply

I had this problem last year on my vision coin in jam I replaced my IGT S2000 504  Backplane motherboard and the coin in jam went away before that
I changed the vacume floor display the I/O board and swaped out mother boards nothing happened when I switched the Backplane it went away at least on my machine
Good Luck

ok i just changed both I/O boards, the back mother board and power supply. i put the main board in another machine and it boots up and works fine then when i put it back in the other machine it still comes up with the coin in jam. 2 other things theres no hopper in it and there was no vfd driver board in it when i got it. i put the driver board in and it and i was wondering if that had any thing to do with it cause i know theres diffrent versions on the eprom that goes in it? i cant think of any thing else to swap out iam open to any suggestions

I see you said it has no hopper. Does the machine have a coin comparitor installed and if not, does it have the jumper plug installed on the door harness where the comparitor harness normally plugs in?

yeah it has coin comparitor in it

When I had a persistant coin jam problem awhile back it ended up being a bad version chip, highly unusual deal. All the boards you've swapped out work fine in other machines? Are you getting any other messages on the VFD display along with that coin in jam error?

yeah all the boards work fine in other machines. and the only other messages is call attendent. but theres a 8 lit in the win meter whats that about any clue?

I don't know what the 8 would be. S2000 machines don't use numeric error codes like s+ machines do and you changed the MPU so there shouldn't be any credits on the machine much less in the winner paid window. When you swapped comparitors did you change the coin optics too?

i never swapped comparitors. and there is no credits on the machine

Have you tried swapping out the players display
if no credits on the machine the Coin/Credits played should be the only part of the players display.
one with the 7 segment LED's it is not the blue VFD display.
Next would be check the door harness out (one that connects between the Door I/O and the buttons, coin comparator, coin optics, and the players display

no i never changed the display i can try it. but i checked the harness and they all seem good and pluged in. but i will swap out the display and see what happens

ok swapped displays and put a hopper in the 8 is gone from the dispaly but still saying coin in jam  :37-

have you opened/closed the main door a few times?  stacked errors are sometimes a pain.

also do you have a sample coin in your comparator?  clear dust/debris from coin in optics?

post up your game/base versions and vfd driver board version and we'll see if they're compatible for you.  :89-

yeah i opened and closed the door. theres a quarter in the comparator the coin optics seem clean no dust or dirt.
vs011gx1
sg000598
sb001000
ss6173
vfd00002
but if i take the main board and put it in another machine it will boot up and work fine with no errors

from the PSR for SG598:

The VFD program controls the vacuum fluorescent display. The label indicates VACUUM FLOR DISPLAY and the VFD number. VFD00007 is required for controller boards with part number 75117700. VFDF3001 is required for controller boards with part number 75120400. Some game themes require an additional display. The number (VFD1xxxx) is dependent on the game theme

see if you have a VFD00007 chip in another machine and give that a try!  :3-

i think i have the vfd0007 i will try it and see what happens

changed it from the 00002 to the 00007 and no change still giving the coin in jam error

Did you try swapping the other Display with a known good one?

If you have the parts, try swapping the complete coin mech w/ bracket assembly and the harness from the assembly to the door harness

i swapped the display last night and still get the error
i will try swapping out the coin mech and harness and see what happens

 I still think its the CPU board  . I had one that baffled me . the board worked in a diferant machine but not in the on that errored.  just an idea try try and try again

swapped out the coin mech and harness still errors
i could try another mpu but i dont see how it would work in one and give a error in another but i will try any thing at this point

try swapping the door I/O cards before you pull your mpu.  what part number are your door I/O's?

another thought is your version chip is for multi-denom but your ss chip is single denom only.  i don't know if it makes any difference but if you have a version VS011GX0 you could give that a try.  i'm sure some of the others can verify if the GX1 works with the old ss programs installed.

if you try another mpu and it works i would put the "coin in jam" mpu into another machine and try to get it to work.  you wrote earlier that the "coin in jam" board boots up in another machine but did you get it fully ready for play?  did you play a few games/drop a few coins in with that mpu in another cabinet?  run some I/O tests and see what happens.

ok good news and bad news. i found a gray wire that was cut that goes to the back mother board at one of the top plugs so i put a butt connector on it and the coin in jam error is gone the deck buttons work now and i can access the options nowand the machine seems normal and ready to play. but another error came up it says machine type mismach now what do i do  :103-

I'm not sure if you have to do a clear, but for sure you have to put a key chip in it and reset the type machine.( maybe all the settings )  It's really no big deal after what you have gone through.

great news that you found the problem!!  :3- no more looking at that really annoying "coin in jam" message!!  :71- :71-

i second Buzz's suggestion of a keychip procedure.  :50-

yeah i know all that for a cut wire. i will try my key chip and see what happens. thanks for all the help and suggestions and i will let you guys know here in a bit what it does

get out the key chip

got it going but i cant change the demoation its on $5000 is key 17 the right key chip?

nope...also from the SG598 PSR:

The key chip is required to change some game options, such as the denomination. The key chip is labeled with the key chip number KEY00045 (or its replacement).

  :37- :37- :37- :37- :37-

one thing after another lol well at least the machine works now

HAY its only $5000 call up STAZ  he will play it     lol    :72- :97-

good to see you can still lol about it.  way to stick through it keith, you'll be an S2000 pro soon if you keep this kind of troubleshooting up!!  i am glad your game is functional, a bit pricey for my taste but to each their own!  :200- :259- for having a good outlook on it; many would have thrown the screwdriver through the reel glass by now!

i wanted to go to lowes and buy a nice new hammer to beat the hell out of it. but thanks again to every one for the help and suggestions and all it was just a cut wire.

You can use key 31 with 598.
I and Buzz both use Key 31.

the only ones i got are 5 ,17, 22, 28  :37-

  Did I miss something ??  I think we forgot the golden rule.  To change the denom you must first use a clear chip. (097)

Foster is correct I do use a Key 31 for most SG chips. I use this rule of thumb, first no matter what  SG chips that are installed I try a Key 31 and if it fails I start looking at a PAR sheet to see what I should have used. Now let me be very clear, I've never had to look at a PAR because a Key 31 has never failed to key a machine. I could give a S*** less what IGT tells me I should use, all I care about is a Key 31 gets the machine up and working !!!

Keith   If I were you I would try clearing the machine and try the 17 you have.  Forget that for now, give me time to burn a set of 598 and a key 17 and I will clear a machine and see if they will work.

you only require clear to change accounting denomination. key chip will change coin\credit denomination

If his accounting denomination is set to 5k it'll have to be cleared.

Lets go back to the drawing board. In reply #27 Keith said he has a Machine Type Mismatch I'm going to assume a key 17 fixed that. That being said A Key 17 will key his machine. If that's true as knagl pointed out his Accounting Denom. must be set at 5K and a clear needs to be done.

I tried my little experiment with a set of SG000598 and  key's 17, 05, 22, and a 31    The key 31 is the only one that worked. Truth of the matter is I think the 2 different files I have for a Key 17 are no good, so wasn't much of a experiment was it.

yeah the accounting is on 5000 so it will need cleared right?

Yep, gonna need to clear it and start from scratch

A clear is needed since your Accounting Denom is 5K.

thats no big deal at least it works now

Keith  Before you do a clear, did the Key 17 work with the Game chips you are using ?? ( SG000598 ) I think it did because you got rid of the " Machine Type Mismatch " error. If it did I would say go ahead and do a clear. If it didn't and you want to play the game with the 5K wait until you get your hands on another Key chip.

 I can tell you for a fact, today I cleared and keyed a Wild Cherry 3 reel SB100095 and SG000598 using a clear 97 and a Key 31.

i never did a clear i dont have the 97 chip or the 31 key. but when i used the 17 key it took the mismatch error away. then if i use the 17 i can get in to the settings but it wont let me change the accounting or demo.

If you're real nice to Buzz he'll probably help you out with a clear chip :89-

sweet  :3-

This has been posted before and I'm not sure just what is cleared when you switch the two Cmos chips. Someone else needs to jump in here that knows. Hell give me a couple of hours and I will see what happens. First gotta cook up some Shrimp for my Sons and me. ( would it be me or I ) who cares. ( David )

The one thing I do know about the CMOS chips. if you bend one of the legs, when you try to straighten it, it will break off. ( Ask Stat )  Bunker and I PMed about them and I think Bunker came up with a price of around 18 bucks each.

 :186- pulling the static ram chips will clear errors and wipe out your history on the machine but won't help with any keychip options.  for the accounting denom change a clear chip then keychip must be used.  :89- :89- :37- :37-

If you have burner you can clear the EEPROM on the Motherboard.
Just write a clear buffer (filled with FF) to it.
It is the only IC in a socket.
Best to remove the cover to get to it.

Clear 97 seams to work for me.
