Netplex link down and connector nightmare
« on: October 18, 2017, 07:28:57 AM »
Hi.... total newbie at slots but have many years experience of other computers and electrical components. I am working on an S2000 Double Gold for a good friend of mine who inherited it from his brothers passing. He couldn't power it up so he brought it to me (power cord would have been helpful, luckily I had one). I lurked and read as much as I could before attempting to troubleshoot it once I got it powered. It powered off fine but came up with the netplex error. Turned machine back off, pulled mpu. Extensive Varta damage. Ordered new board and power supply just to be safe and have a back up supply if need be. It was very obvious that he or someone else had unplugged the connectors.... all of them at one time or another as they were taped tagged and a piece of paper was inside the machine handwritten on where most all of them should go. Got the new board in loaded it up with the old power supply same issue, new power supply doesn't change it either.


The error shows The Display Netplex Link is down. I followed the wiring around and it is plugged into the Netplex 2 on the lowest power distribution panel. Since I don't know where they were originally plugged into I don't know if that is correct or if that is the problem.


If anyone could walk me through this I appreciate it. He also wants it to be setup for coins. I have already gotten the hopper and bracket, the coin head assembly with the comparitor and a 31 chip but obviously must tackle this netplex first. Thank you so much in advance!

 :NLG_WELCOME:
Please post a picture of your MPU board.
Is it a 500 series or 1270 enhanced?
We should be able to get you up and running.

I can't tell but is there a varta battery on this board?

If you want to post pics of the connectors we can look at that too.

That's a 1270 board. Chances are the varta battery is dead and this is causing your netplex error. The good news is the Varta can be removed but you will have to also remove the regulator chip at u16. They are not needed for home use.
See link for details.

Nothing needs to be plugged into the display it is OK as is.
Since that is your replacement board and the Varta looks pretty good it may just need to charge up a little.
Go ahead and install the MPU turn the machine on an leave it on for an hour or so then cycle the on off switch and see if it comes up.
I would also modify your old board by removing the old Varta and carefully snip the three legs of the U16 chip carefully the bend the chip until the chip snaps off. If the board is not too damaged from battery leakage it may be a good spare.

The last plug shown may or may not need to be plugged in you need to see where the wires lead. Chances are it's OK as is.

I did power it up and let it sit for about 2 hours last night before posting and no change.... should I do it longer?


The other board was toast in that area.....worst damage to a  board I have personally ever laid eyes on.

That harness is for the back lite reels .. no controller board for it to plug into. No effect on machine booting up.

Two hours is long enough.

Practice on the old board .. I pull the battery back towards the edge of the board, slide a pick in between the battery and tab, there are two spots that are spot welded, I break one at a time, bend tab back and forth until it breaks, then the other side I hold the battery and bend it back and forth until it breaks. It could work once U 16 is out.

Like qbert mentions .. snip the three legs then lift and bend back and forth

Yay for small victories. Varta and u16 gone and it booted up and after 4 turns of the key it now says Please close the main door but the main door is closed. The optics appear to be in line. Any advice for that?

The machine has been moved from it's original location.  The cases on the S2000s are flimsy at best I still think optic alignment is the issue. Try lifting the door handle about an 1/8 of an inch and see what happens.
Is the belly door switch bypassed if not make sure the belly glass door fully closed.

Make sure the latch goes all the way down also.
Best way to align door optics is to open the door, put the latch all the way down. Then put a piece of masking tape on the outside of the door and draw a horizontal line indicating where the optic is located. Take another piece of masking tape and place it on the case outside where the optics are, close the door put the latch all the way down and extend the line you put on the door across to the tape on the case.
Open the door and move the optic in the case to match where the line is that you put on the outside of the case.

there is also a way to make sure the machine is actually producing a optic signal, or if the cpu is actually seeing it.  get into the test mode, (open door, press the button on the cpu near the LED lights) scroll down to machine tests section #4,Input tests,  processor tests, door optic test,  close and latch the door, if the 1 is changing back and forth to a 1 & 0 then the optics are working, if not, you can slowly raise the latch until you notice the change,  if no change, then something in the optics loop is bad. either bad optics themselves, wiring, or the board itself.  but, without the optics working , your machine will never work.

Still with the door error. So I decided to explore it all my connectors that need to be plugged in are plugged. Since someone has obviously tinkered with it already. 


The first couple connectors in question are in the attached photo and pertain to the cabinet I/O. The is a short 2 port connector wire colors are light green/grey and black and red.  The second question is is there something supposed to be connected on the other side of that I/O board.

1)Normal for nothing going to the plug in question.
2)Plug in the I/O card is for back light reels if you don't have back light reels then nothing goes there.

Check your two optics for broken wires they are fragile and can break easily also make sure they are plugged in.
Optic in door wire colors are black and red. Optic wire colors in cabinet are red and white
