Machine Type Mismatch Error

[Buzz]

I guess I lied and I'm back one more time.
 
Eric  If your reply in #30 was correct you have the solution to your problem. No MPU, No Mother Boards, No Netplex, and NO changing the lower light bulb in the candle.  In door optic test when the latch is down the 0 and 1 will pulse from one to the other. No pulse, adjust the optics !!  If when the optics are adjusted properly there is no pulse exchange the optics with  your other machine, but only exchange them one at a time. ( one at a time will tell you which one is bad )
 
To adjust the optics,  place some tape on the cabinet and door. Using a Sharpie draw a line on the tape that is lined up with the center of the optic. Close the door and if the Sharpie lines do not line up the optics need adjusted.
 
OK with a good working set of door optics and with the BV and cash can removed from the machine, ( you really don't have to remove them, but in this case please do ) Now open and close the door latch three or four times. All the BV errors will clear, now install the BV and cash can and see if the error comes back.
 
 what they are telling you about going to Netplex Config everytime you change BVs in a S 2000 is bull shit. If after changing BVs is a S 2000 if you see CRC mismatch on the VFD just open and close the main door latch a few times and the machine will adjust for the new CRC.
 
Tricks of the trade  OK the tricks of my trade are trying to shift a 18 speed transmission as smooth as I can and getting from point A to point B without getting a speeding ticket or a overload ticket. I'm no slot tech, three ways I've learned about slot machines, the commen sense way, the hard way and about 6 years ago I enrolled in this sort of slot tech school. Name of that school is New Life Games and up until a couple of months ago I  Read every post that was on the kind of machines I own. 90 percent of those post are bull shit but every now and then you will learn something new. This one is hard to believe but in almost 6 years I only ask for help on a machine two times and got NO reply on one of them.

Hey thanks Buzz,
I did get the optics somewhat adjusted ...I was going to go get a hinge to replace the one on the door...It has a nice sag in it when you open it..after that I will see if I can get them lined up better, if I have to, like you said I will swap it out with the other machine ...one at a time ....I will mess with it probably this weekend ..I had to walk away from it for a couple of days and take a break....
Thanks again for the reply

Who cares if the door sags when it's open !! Your not using the optics when the door is open, but you can bet your butt when the door is closed the optics are in no different alignment with the old hinge are  new one.  Besides I'll bet the hinge you have is not the blame for the sag.  Do this, with the door open a small amount lift up on the bottom of it and watch the cabinet flex. They are just piss poor cabinets, you will never see a Williams cabinet flex like a IGT does.  If you happen to have a arc welder, tac two pieces of 1 1/2 or 2 inch angel iron to the floor and each side, it helps.  Wire feed works best if you have one.

Update messed around with the machine a little more ....tried adjusted the door optics..no change ..replaced optics with ones out of my other working machine ...bv errors went away but then received the machine mismatch again ....weird  as I was scratching my head and staring at the machine ..I happened to have the belly glass removed and I pushed on the light plate on the left hand side where the belly door cherry switch is ....bingo error gone and game waiting to play mode ......go figure .....replaced with one from the other machine ....game plays fine ....I have some other minor issues .....not error related ,but I will read up on those at a later time .....So with the bad battery to start and door optic problems, I will know next time the first things to look for when errors occur ....Thanks to everyone who helped me out ....many many thanks .....I'm always learning more and more about how these machines work.

For the belly door cherry switch you can bypass it by tying the 2 wires together, you will never have to worry about that again. I do this to all my machines along with the cash can wires.

Yep, lesson to remember here is ALL DOOR OPTICS ARE RELATED!!! Yah! Glad you got it!!!
