New Life Games Tech Forums

hi all,

I have some i game boards that are saying " coin in jam and meter disconnected" anyone have solutions?

according to some helpful info that Belbenchtech has posted in his "repair logs of various games," U74 could be your culprit.  good luck!

Thanks a bunch. I'll check on that.

I found out today that if the little board is missing that is along side the MPU board you will get a "reels disconnected error"  The board pulls out of the outer case and you might not even know anything went in there.  I stuck one in and that error went bye bye, Along with coin in jam !  I will try to get a picture up soon.

So you guys, is this U74 ?

NO, that is the Cabinet I/O, U-74 is a IC chip on the I+ Video 3902 MPU board

Well what ever it is, it was missing and when I replaced it the "reels disconnected and coin out jam" went away.

Try it, see if the 2 codes return.

Funny  I had same thing today on texas tea , 1st thing i did was change that board , still nothing, game use to work 6 months ago,  I got out some contact spray  put it on plug l put board in and out a few times about ten mims later i turned on game and now its working  , seems plug in cabinet was dirty

I don't want to beat a dead horse but I just pulled mine and rebooted and got the "reels disconnected" ... put it back and all gone.

ok, the horse is dead now, this might help someone.

Hey guys on the forum, I hope I can help with the following problem: I have a processor IGT model IGAME + that is throwing the error Coin Jam and Meters Discconected, have rejected other than the door card, I have also changed the U74 is MM74C240WM. Of course I appreciate any help and suggestions you can reach me.

 Regards Philip

The meters are connected to the Cabinet I/O Card
Coin optics are connected to the Door I/O
both are Connected to the MPU through SENET ports on the motherboard.

hi Philip,

is there any chance that the meters are actually disconnected?  or maybe there really is a coin in jam?  or it could be a problem with either of the aforementioned assemblies.  i've had hard meters go bad a few times, especially when they are given a drink!  :30-  also could be bad or really dirty coin in optics if you have them.  if the coin in assembly has been removed make sure the plug for the assembly is properly jumped as well.  :89- maybe start looking for pinched wires, especially near the door hinge.
if none of this helps i would probably swap the mpu with a known good to eliminate a possible SENET failure as Foster mentioned. :50- :50-
good luck!!

Hi there, looks I am not the only one with this issue..

My I game Plus Ghost Island started showing the following tilt errors out of the blue while somebody was busy playing it, machine closed, credits there...

-coin in jam
-coin out jam
-meter disconnected.

So nobody disconnected anything 'hot'.

Furthermore all standard buttons are without function, also in test mode, no switch impuls, no light, only the 5? extra on top which are connected to the cabinet I/O board light up ALWAYS, but also no function. I/O board did NOT swap, cos only have the one.

I did the following:
checked and cleaned all contacts and cables
swapped both powersupplies with good ones from other I game
swapped and checked motherboard, no problem found
swapped the board assemly tray on top of MPU tray, which slides in the motherboard also and has most cables connected coming from the door
swapped / disconnected and reconnected hopper
did key chip complete RAM, EPROM and EEPROM clear 2 times, which in the keychip menu says "NO TILTS", after setup and exit key chip menu, the error messages come up again, not the coin out jam anymore.

Note: the machine is otherwise in very good condition, no power surge issues or other, MPU battery good, graphics good, sound good, BV starts up fine. The machine does only have one I/O board in the cabinet stucked in on top of power supply on left side. I/O board number: 75427802

After doing some reading here I have reason to believe the I/O board and / or the MPU is burned somewhere . However I do not visually find any blown elements, nowhere.
Now after I put back all the parts in the other machine which I used to swap the mentioned parts, now on start up the other machine also gives me a 'meter disconnected tilt, and a coin in jam tilt which disappeared later, I am without ideas how thats possible. Maybe faulty voltages DC from PS? where can I measure the voltages coming from the PSs?

Anyhow I would appreciate alot any advice and idea as to what should be replaced or checked further, maybe in the setup or diagnostics. i.e. hopper test says clear coin out jam first, only there is none...

From my place it looks like I should have another I/O board plus another MPU complete without the game software. I will order the parts twice to be sent to Namibia and Angola, cos things disappear along the way frequently...

If you recommend other or additional parts please advise. Is abit far off here to find competent people nearby.

Thanks alot everybody patient enough to reply

I had a coin-in jam yesterday and it turned out to be that the I/O card in the door was loose.  I push it back in and the machine cleared itself.

hi,
thanx, I think I don't have a I/O card in the door. where exactly shoul it be and look like? the same like the cabinet one?

Yep, looks like the cabinet IO and it's probably located on the inside of the sheetmetal panel screwed to the door. All your deck switches, coin handling and BV wiring go into it and it passes signals on to the motherboard. The only thing that it doesn't process on the door is the BV bezel lighting and the door florescent lighting.

nope. for sure I do not have such a board, I took apart most of the door last night, all the cabling (not the bezel light) which are not going to the other I/O board go to that strange big tray inside the cabinet sitting parallel on top of MPU and slides in the motherboard.

Hmmm, sounds like Igames are wired a little differantly, gonna have to get one and study it :89- Have you checked the seating and pins on the cabinet IO?

yes but all my I games and Game Kings have that 'tray' which contains 2 boards by the way and are connected to the motherboard the same way the MPU is just more upwards. Yes I tried that and studied the I/O visually very carefully, looks basically new to me, the tray with the 2 boards embedded I swapped as I mentioned, same result, errors stay. I read somewhere about U 74 could be the culprit. what is it ? do I find it on the main board?
thanx alot so far, but I never had anything like that..

Hey Busch!
Make sure the power is "OFF" on the machine when pulling/inserting those I/O cards -
they burn really easy!
I know! I'm on my second set!  :8-

Yes thanx, thing is what happened is this:

My I game Plus Ghost Island started showing the following tilt errors out of the blue while somebody was busy playing it, machine closed, credits there...

-coin in jam
-coin out jam
-meter disconnected.

So nobody disconnected anything 'hot'.

I think Bunkers just giving a heads up on not pulling any plugs or boards with the machine powered up while in the process of trying to track down what's causing the problem. I don't think he was refering to it as the original cause. We've had people before who made things worse by trying to move things along to fast and causing more damage by removing boards/plugs with the machine turned on

yes is understood, that why my thank you, happened to me before to out of growing desperation and helpless anger, you know...
hey stayouttadabunker really I appreciat the warning/hint.
So what would you do? just buy new I/O board and MPU maybe, see what happens, only will be not cheap to have it couriered over here, and does NOT work, if it fixes the problem is easily worth it I guess. I want to check those voltages of the Power supply also DC, if there is a problem cos other machine does the same now after PS swap.
And I will need I think that 'funny tray' boards, 2 of them, just to rule that out too.
Hope I find a vendor who is fast and willing to send overseas, which is quite tricky at times in the US.

Hello Busch

Good to see You back on the forum - From what You describe it sounds like You have the original model I game with 038 processor. Dont know if parts for these are as readily available as for the more common 039 parts. I have attached a schematic for the IO board that may help.

Ian

Hi Ian,
yes I am still around sort of, hopeall good there your side.
I am not sure where to verify the version of processor. All I know is there is no 2nd I/O board in the door.That problem is more complex than I thought cos affects another machine too now which eludes me why.
I just want to renew all parts which can possibly cause the errors, and I need to do it fast. I have no tme for endless troubleshooting, so I rather just replace whole components and can later see to check the original parts.

I don't have the schematics of the power supply readily available on-hand Busch
but it's also possible that there's just some dirty, oxidized pins too!  :71-
I'm also not sure which model PS you have either.

Would you have some electronics contact spray cleaner around?
I'd spray some pins too!
It doesn't hurt to have clean pins in the Molex connectors!

about the PSs is true, I figure out a way to see the DC powers. The pins and all I cleaned thoroughly with contact cleaner etc, all pin and other contacts I could find. I think best way to go is replace all components which might be or contribute to the errors, I am busy checking around, any business affiliated here I give preference if possible.
Thanks again, I am not so worried about the problem per se, looks like is common, but the way it just appeared while machine was in play...

so long

Hi again,
looks like my problems with I games continue. Are these games generally unreliable? I have a couple of Game Makers, they hardly ever give me trouble, and if, I can resolve it normally. Never my I games or Game Kings work more than 2 or 3 months without trrouble.
 How are those newer Ballys, Alpha or 9000 in terms of reliability? any experrience there? I have 3 GameMagic, all 3 out of order after short time, nobody coud help.
Yesterday another one broke down: Cleopatra, while on idle, a very loud explosion inside, smoke and all, I found the 2nd battery on MPU burned totally! why no idea.
Cleaned and changed and checked, now on power up the monitor only displays those funny coloured squares...with other board is ok, so I need another board there also I guess.
Now: is there anybody who could sell to me those parts and ship to Africa ( I/O boards, MPUs, DC powersupplies) sound easy, but so far I found nobody. I checked the links given in this forum...
thank you for any info

I have a coin in jam on a igt gameking bar top, the game has a jumper and i changed out the i/o cards.any idea on what i can do to fix this problem

if you have machines dyeing on a regular bases something is probably wrong with your power line. if you are missing i/o boards in a previously working machine you have a thief their is no way for an igt s2000 or igame to work with out a door or cabinet i/o board. some machines maybe have multiple of each board depending on the displays and buttons it is configured with. if your game is supposed to have multiple of one type of board the error displayed may not be the correct fault, a lot the SENET devices are chained into each other and i have seen the mpu get confused.
