working on a s2000 3 reel wild cherry, during start up, the door display, buttons blink on and off, for along time, says door is open, closure m and so on. battery is new and 3.6 volts, tryed switching, power supplies, door controller box, nothing seems to work.after some time, its starts working on its own, and is fine until shut off again. checked wiring and plugs, and find nothing wrong. any idea whats going on???????

Does sound like a short or power problem but I would try and switch MPU boards and see if it helps

Make sure your door is closing all the way. I had a 2000 that where the door latches to main cabnet at top was pulled out on
cabnet. Took a hammer & punch & taped it in on cabnet & that took care of it.

just upgraded the mpu, worked fine for about a year, maybe the door optics, but would not think it would just start working after time.

it does this door open or closed, if it happens, during play, reels spin slowly, reset it and it sta over again. then works fine.

Does the MPU board have a corroding green nicad battery installed on it?

rarestamx,

Make sure the machine is perfectly level
a main door slightly out of whack will cause this error,
as suggested above check the green battery for corrosion located at BT2 position on the MPU
in fact for a home slot user this battery is not needed and causes more problems than it's worth.
It should be removed anyway.

If none of the above works maybe try swapping optics from another S2000 if you have one
you could drop another MPU in it and see if the error goes away
which would shed some light on it being the MPU or cabinet.

Before you do a lot of switchig check @ top latch like I mentioned earlier.
You may think I'm nuts but check it. Mine acted the same as yours. I went
nuts until I found it.

Hello all!

I've posted this before...

I went round and round with this same kind of problem for months.

In my case - it was the belly glass door.  Some machines have a door switch in the upper left corner of the belly glass door.  If your machine has this switch - it will also show as a "Closure M".  Not all machines have this switch.

I would bump the belly glass with my body or knee during a spin and the reels would go into the slow spin.  I assumed it was my main door and optics/etc.

So make sure and check if your belly glass has a door switch - I have removed mine and shorted the wires together....

Glad you got it going. Most of the time it's something simple.

The S2000's are famous for these type problems. What I have done is made a piece of wire about four foot long and put a pin on each end that will fit into the door optics connectors. Not the optics itself but the connector going to the mother board. Short out the red/white wire and the green wire on the other end. This should fake out the door closed circuit. You can now play the machine with the door open. If the machine plays okay then the wiring, mother board, and mpu board are okay and the prolem lies with the optics. This also helps with other problems when you can play the machine and see inside as well. Hope this helps.

I had the same thing and my game would blink 3 times off than go on. It would do that in a pattern for 10 min. or more than stay on. I tried everything and finely decided to clean my board, I removed all my chips, I cleaned the pins and reinstalled them. I used caned air and cleaned all the dust under all the other chips.  I cleaned the bottom of the board with alcohol.  Reinstalled, cleared and the problem went away.  Why it worked I do not know, but it has been working ever since.   

thanks for all the help, will try each idea one at a time. if it is the door optics, how do you set them, to be correct, sounds like they must be very sensitive
