Do you mean the 3 pins smt chip that seems to be a regulator?

 NLG Welcome hello woilly!!

U67 on an S2000 mpu is a 20 leg surface mount buffer/line driver.  you can find it by looking just south of the static ram chips.  the part number is MM74C240WM (at least on the 504 board i'm looking at) and mouser.com has about 700 of them in stock right now but also shows that this part is not being produced any longer.  at $6.50 for the part and the time and effort to perform the surface mount soldering required you could probably pick up a used, functional mpu on eBay instead of dealing with the hassle of fixing it.  yes

but if you decide to dig in then good luck with the repair!!  lightning bolt

Hi, Thanks for the answer, I forgot to mentionned that i'm working on CPU board p/n 75512701. This the board with the piggy back card you can add on it with the game.  I think your talking about the p/n 75503902 with the I960 intel processir ant U39 as base chip.

The CPU board i have, as no base chip on it. It's all on the piggy back card, game and key chip....

The problem i have with this board (have couple of it with same problem) is : Netplex link is down and the only way to tunn the machine back on is to let it on with the error and after 5 min swtich the power off and On and the machine restert.  After that you can not perform a shut down without doing these steps mentionned above.  On some board the problem stays and have to to be changed to solve the problem.

I know that the powert supply behind the reel can cause the problem ( C50) but in this case the problem is on the board.

Thanks

hi again woilly  wave

yeah i was referring to an 80960 S2000 mpu board (p/n 75510504) because that's where the previous discussion was at. when you reawakened this post i guessed that you were having the same issue as was discussed previously.  cheese the 75503902 you mentioned is the GameKing video processor board but the 504 and 902 boards do use the same processor - intel i960.  yes
i know the newer mpu that you are having your issues with but unfortunately (for you, not me Tongue Out ) i haven't run into any netplex down errors in any of our games using these mpu's. do you have a schematic for the 75512701 board?  i don't but i have a request in to IGT for one so maybe they'll feel friendly enough to share a copy with me soon.  if so i'll try to send it to you via email; my IT department tries to block all of my attachments though so no promises! your problem sounds very strange to me...components sometimes don't like to work after a cool down so maybe your 5 minute warm up time is heating a weak component up enough for it to work after the quick reboot? just a hypothesis there, no data or testing to back it up and call it a theory.  propeller good luck, if you find a solution please post for all of us to learn from.  yummy yummy

edit: just a thought as well  Scratch Head ...you mentioned that you are familiar with the C50 cap problem on the DC switching power supply causing a netplex link down.  is C50 the only cap you changed in the power supplies of the games you are experiencing this netplex link down error on?  we always shotgun the electrolytic caps in these power supplies once they fail because caps are relatively cheap and if one has dried up enough to fail then others are probably not far behind.  i would change out every electrolytic cap you have a replacement for and see if the problem goes away.  maybe you've already convinced yourself that the power supply isn't the problem and are overlooking it?  just some food for thought, please don't be offended.  i'm not trying to berate your slot tech skills at all, just hoping to help.  yes

How can connect Win-Tact WP206F11 PR5 (36 pin connector) for testing?

The AC input pins are Blue and brown,
Green is Ground.

US wiring since neutral is involved.
24 115/230 VAC blue insulation
22 Neutral brown insulation
20 115/230 VAC but nothing connected to it, in the diagrams and my machine harness has nothing connected to it.
11 Ground

if you are looking at the supply connector facing you.
They are like this

24 23 22 21 20 19 18 17 16 15 14 13
12 11 10   9  8   7   6  5   4   3  2   1

Mounted in an upright the AC input is towards the bottom.

thanks Foster for replay.
But how I write I have the newer supply wit 36 pin connector model PR5.
Your right for model PR3 with 24 pin connector.

Anyone have the schematics and common faults for Rev.A7?

PR3 is Rev.A4

A way to check this is to make a test rig out of an extension cord. Cut the recepticle end of the extension cord off and crimp on connectors that will fit the pins in the power supply. Contect line voltage to pin 24 and 22 and connect ground to pin 11. Plug into any outlet. Now measure voltage using pin 17 as ground for your meter. Pin 1,2 and 13 should read 13V. Pin 3,14,and 15 should read 25V. Pin 7 should read 5-7V. Pin 7 is used for a logic signal. If all the voltages except pin 7 are present you will get the infamous "display netplex link down" error. On he win-tact power suppies this usually indicates circuit board 2 is defective.
I have a autec power systems 552-1340 and check as indicated above and do have all the correct voltages. does that mean that this power supply is good?

I found a CN from IGT to changed bad power supplies,because of bad parts.(attached) CN 3648A
SuzoHapp got a set for repair too.

the board SAT put a picture up of is the vacuum fluorescent display(VFD) driver board.  not a common failure but happens occasionally, there is a surface mount cap that has been the problem 4 out of 5 times for us.  i can't remember the value off the top of my head, but i believe it is designated as C3 on the board.

also on an S2000 the netplex components are your Bill Validator, Thermal Printer, VFD, 7 Seg, and Spectrum Display.  a problem with either of these can take netplex down.

that being said, probably 95% of our 'netplex link down' errors in the past 3 years have been due to the DC switching power supply behind the reels.  we have been repairing them for probably 2 years by shotgunning electrolytic caps with a 85-90% repair rate.

edit:  the value on the surface mount cap for the VFD driver board is 4.7uf, 16V

I was getting the netplex error but I am without any technical knowledge, after reading these posts I went with swapping out the power supply, a win-tact for a sy something I got off ebay and it seems to have solved the problem, no more errors.  I can't tell you how much I appreciate the knowledge shared on this forum.

ON THE WNTACT POWER SUPPLIES THERE ARE SEVERAL VOLTAGE DETECTING,SYSTEM RESETTING IC'S M51957XXX.  ONTHE WP203F11 THE IC FOR THE NETPLIX ERROR IS LOCATED ON THE CONTROL 2 BOARD (CTR2) AND IS IC4.  WHILE YOU HAVE THIS BOARD OUT YOU MIGHT AS WELL CHANGE Q3 AND THE ELECTROLYTIC CAPS.  iF YOU NEED MORE HELP I HAVE THE SCHEMATICS FOR THE 203, 206, AND 207 UNITS.
