S2000 Machine Will Not Clear! HELP!!!

[Buzz]

OK I just went one step futher, I took a 9 line display from a second machine and installed it in the first machine. NO coin error. Bottom line is I have 3 displays (1) 5 line and (2) 9 line Two of the displays the machine plays and 1 display I get a coin error. Case closed.

Buzz that is a different issue than what I in 2007 and freebird4 recently was having with coin in jam error on our machines.

I could not clear mine, but doing what I did to mine got it working.
I am one of the first few on here with a Vision Ready or S2000 in 2007.

I will say this sometimes even the guru's get stumped why a simple tilt wont go away.
When we try every thing known at the time but try something that is overkill and it goes away.

Those are good pictures Buzz and definitely states the case but it brings up a question in my mind as to
how in the world does a bad, non-working line bet display cause the the MPU to output that particular error?
That's what confuses me. 

I know the SB or SG chips store messages such as "Bad Display", or "bad VFD display" and
you'd think the MPU would throw out those error codes instead?
It just shows you how hard it is to diagnose these machines when one would think a "Coin-In Jam" error
would be related to the coin mechanism area.

Does the MPU throw out a "Coin-In Jam" error if you have the "wrong" display installed instead of a bad, non-working display?
I was just wondering because I don't have any non-working displays to try...

stayouttadabunker, Buzz is correct it definitely can. Don't know why. That same display caused me to get a coin in jam on a coin less machine. Mine had a burnt spot on it.

Ouch! The IC component at location R36 is blown up as well as it's surrounding traces big time.
That's NOT an easy fix considering the tiny size of those traces in there.

I'm not saying that Buzz is wrong at all...I believe he stumbled onto the fix by swapping around displays and parts.
My question was why we get a "Coin-In Jam" error instead of a more appropriate "Bad Display" error.
Thanks for showing us that blown up board.  
Mine was blown up too last year near the 14-pin white Molex header but I was able to get some parts from coorslight's son to repair it.
I blew mine up by plugging it in while the power was "On".  
That's a big no no with any of these I/O-driven components.

All of the constant coin in errors I have encountered were caused by the door I/O board being loose or bad. Maybe the board came loose in shipping ???? Thanks

It's very likely and I agree with you too.
I've learned enough that's it's never good to turn on a machine without first pushing in
everything that could possibly come loose during movement or shipping.
The worst thing that you can do is power up a machine
and a loose I/O card shorts itself out...meaning more  to shell out for new parts!

Which card is the I/O card?  I've never messed with one.  Just curious.

Jason  I'll tell you like I would tell Staz, If you don't know, don't  F**k  with it. 

5 button deck you have two ( they are different part #) one is located on the MPU chassis ( the one you plug your backlit cable into) the other is located between the belly glass and inner door panel to the right of coin comparitor.

10 button has two of them on the door, one inside one outside inner door panel. And the one on the MPU chassis.

[Yoeddy1]

Thanks Buzz.  Just wanted to know where it/they were located.

I have had some machines that have had the door IO tie wrapped so it can't come loose. Makes you think this is a problem even in a Casino.

This machine was sold and when they got it home it only played a couple on spins and got the coin error.  Next day we took another machine to them and swapped out the MPU and kit and brought the bad machine back to the house. I think they told my Son they saw a extra light hanging below the button deck and they messed with it. Lord forbid one of our OCD nit pickers get a 10 button machine that has extra unused lights hanging below the buttons. I can see 75 post asking where to put the light.

Bunker in this case no IO's were harmed, only the display. ( no burn marks on the display ) You would think when I plug in a 5 line display into a 9 line machine I would get a error but I don't, the machine excepts it.

That makes sense don't it?  

Sounds like when I was younger and my '77 Toyota Corolla needed new plugs.
I only had pair of new ones ( didn't know beans about gapping plug either! ) but it sputtered and coughed all the way to Napa Auto parts
where I swapped out the junky plugs right there in the parking lot!
Turned out I needed a new rotor for a smoother engine...

That's great freebird!!

What move did the trick? Swapping out that "Line Bet" board?  
It will help future members when reading this thread!  

[freebird4]

I followed Buzz's suggestion: clear chip, to the key chip, to the SB chip ( in that order ) after doing this I setup printer and etc. and it works great!!! No more coin-in jam error!!!!

Experience makes the difference and Buzz has it!! 

Thanks to all for the suggestions on fixing my problem!!!
