I bought this years ago from a vendor here. S2000 been flawless for years. All casino antitheft stuff removed, basic machine. Replaced the green battery years ago, no issues. When I fire it up the Bill validator runs in fine. The display passes the self test and gives the NETPLEX error. Ive removed the bill validator, and the 3 reels. No ticket printer or other add on devices. Still get the error. But I did notice when the reels were plugged in they did NOT rotate on startup. They normally do. Any ideas? Where is the best place to check the power supply for voltage?

The Varta battery is probably dead. Turn it on and leave it on for an hour or so and it might get enough charge to boot. It really needs to be removed. I assume you have a 1270 enhanced MPU. Removing the Varta also requires removing the IC @ U16 or at least clipping the pins.
Check your board for corrosion in that area. It will ruin your board. It's not needed for home games. It's for a telltale system used by casinos.
Quality doesn't cost. It pays.

Battery was taken out and main battery converted to a CR2032 for easy replacement. I keep thinking that the reels not moving should be telling me something. But I don't have the experience to understand what it means. I was thinking possibly power supply but looking for some direction. The place I bought it from used to have parts but I heard they shut down. So besides figuring out what to do to fix it I'm going to need a new place for parts. I'm in California. Thanks again, Rick

The simplest way to test the power supply is to swap it with a known good power supply. If you don't have access to one, check the voltage outputs, +13vdc and +25vdc.

If the power supply voltage is out of range or lacking, it's obviously bad, assuming its fully seated and making good connection. Beware that a power supply can deliver the proper voltages and still bring down the machine. This is due to power supply pin #7. This pin is for a logic circuit and if the voltage isn't within proper range, it won't boot and will give the NETPLEX Link Down error. The power supply is a common cause for the NETPLEX error, and this logic circuit is often the cause.

How to diagnose a netplex link down error.

First disconnect all netplex drvices except the vfd.  This includes the bill acceptor, printer, some progressive displays, some top box bonus devices. Now that those are disconnected check the following.

Is your error solid or blinking.
Blinking
     Do you have a 50x or 1270 mpu?
     1270
          Remove the varta and u16.
      50x
          Mpu fault.
Solid
     Do you get no disp on your credit display
     No
          The mpu is not booting check the mpu for signs of faults or problems with the chips.
     Yes
          Check voltage at the vfd on the 2 pin connector
          Check the data cable for any signs of damage especially where the door closes.
          Mpu is faulty or damaged check for bent pins.

Pin 7 is sin-in it is a chopped ac voltage so the mpu can detect if the line voltage is stable. It is a huge problem on these igt machines a lot of people overlook. Not only the voltage has to be in spec but also the frequency.

What would be the "proper voltage range" to look for on that pin Retro?
Just wondering...

Depending on how you test it between 5 and 7v ac 60hz is what i typically see on working power supplies.

I used to get parts from Central Valley slots. I heard they closed down. So any recommendations on a vendor for a power supply? Im in NorCal. Thank you!

Have you tried any of the NLG vendors on the home page?
Most have telephone numbers too.
Closest one to you is KLAR outta vegas?

Netplex down error STILL
« Reply #13 on: November 13, 2022, 06:24:43 PM »
Still have NETPLEX down error. Varta battery has been removed, main battery changed to 2032 coin battery, and all worked for years. Unplugged unit and sat for a year. Came up with NETPLEX error when I fired it up. Replaced 2032 battery, replaced power supply, but still have the error. The funny thing was with the old power supply if I left unit turned on for about an hour it would reset. but then going through the KEY and CLEAR process I would end up with the error and stop the process. I removed the reels,bill validator,and coin hopper. Still get NETPLEX error. Any suggestions?

Try disconnecting the printer and the flourescent light ballast on the 24V input side

Why start a new post?  You already had a thread going here and when you abandoned it were going to look for a power supply.

Yes, power supply was purchased from a vendor on this site and replaced. The connector pins and plug looked perfect, no issues. For a while if I left the machine on the fault would clear after about an hour and machine would be ready. However. I tried a Key and clear and can't finish the process. As starting and restarting machine throughout the process eventually the error returns and I can't finish. That is where it is now.
