coin in jam s2000

[keith]

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

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

[keith]

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

[keith]

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

[cowboygames]

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?

[keith]

yeah it has coin comparitor in it

[cowboygames]

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?

[keith]

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?

[cowboygames]

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?

[keith]

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

[Foster]

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

[keith]

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

[keith]

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

[kforeman]

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. 

[keith]

yeah i opened and closed the door. theres a quarter in the comparator the coin optics seem clean no dust or dirt.

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! 

[keith]

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

[keith]

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

[Foster]

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

[cowboygames]

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

[keith]

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

[PLUNGER BOY]

 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

[keith]

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?
