I have come across several bad boards that do that.  Another common bad board error is a coin-in jam.  Tracing out the bad component is nearly impossible.

Hello!

When you say you replaced the power supply, did you replace the one behind the reels?  This is usually the cause of the problem.  Check the thread's I've listed below for more info...

U-67 seems to be a common componet that gets blown on the boards, Have seen a few and you can see the hole in it.

I'm sure idesign thanks you for the K+   looks like he can use it    bust gut laughing

It happened to me that the display driver board was the faulty one... I confirmed it by swapping this board with a working machine.

I'm attaching two pictures of it for you to see both the board and the part #.

Regards!

(BTW: this board is installed in the main door and it's normally covered with a sort of metallic or plastic plate)

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

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.

How can one tell by looking at the PS (with the cover removed) if they have a good version compared to a troublesome version?

I have a work around for the "display netplex link down" error on Win-Tact WP203F11 power supplies. I was tired of throwing them away or finding some components iimpossible to get. First make sure that all three +13V and all three +25V outputs are present and that pin 7 is zero volts. The test procedure above works great for this. This means that the logic siginal is missing form the power supply. If pin 7 is above +3V it is concidered a logic 1 or high -- if it is 0V it is considered a 0 or low.

The work around is to break the connection from pin 7 to pin 13 of the Ctr Bd 2 as shown in the attached picture. I do this with a srew driver or knife and just cut through the lan. The last thing is connect a wire from pin 5 of the CTR BD 2 to pin 7 on the output connector. This is done on the backside of the circuit board. This is using +5V VCC for the logic siginal. This is also shown in one of the pictures.

If you have a win-tact power supply in this shape you might want to give it a try. I have done 10 and they are still ticking.

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.
