Title: Open door MB where to start ?
Post by: adar on March 09, 2023, 08:52:44 PM
Hey guys, just picked up 2 s2000 machines.
Both not working,
1 machine turns on testing memory spin reel and all but then say “open door MB”

Second one completely dead won’t even turn on.
The old owner said both worked before but he left them in a storage in about a year and that what happened after he tried to play again.
Any ideas where to start ? Prob with the one that turns on first 😅
Thanks
Adar

M=main door
B=bill validator door

Post a pic of the MPU board.  Turn machine off before removing it.

What Mark said for the first one.  I suspect we'll see a green varta battery that has leaked on the MPU and damaged it.

For the second one check and make sure the power supply located behind the reels is fully seated in its connector.

so got both of the mpu out

and ill add some photos,
as for the machine that didnt work i already figured it out. i assumed its the power supply so i just used the one from the working machine and the non working started right on, only problem now it saying RAM ERROR
one board look damaged a bit, corrosion maybe ? damaged chips ? should i try clean it with some alcohol ?
i tried them both and its the same with both
RAM ERROR
i did pay attention one got no ram, so i moved it from one board to another but still same problem!
thanks everyone !
really appreciate the help!

The one board has a lot of corrosion.  Is it the one with the Door Open MB error? 

Did you clear the RAM error message?  Turn the jackpot reset key a couple of times and follow the instructions on the VFD.

Hey there, I tried to clean the board with a just toothbrush for now, so before it didn’t clear all the error codes with the key, now it does, but again door open stays even if it close, I looked around a little and it look like the sensor for the door got replaced before, the left the old se sir on the door. And a different one connected.
So before I clean with the toothbrush it said EPROM CRC MISMATCHED.
Now it bypassed it but still saying please close main door.
Photos attached.
Thanks
