S2000 was unplugged for a while. Now I have a Displays NETPLEX link is down. I put in a new main battery, tried a CLEAR chip but still cant get past the error. Any wisdom for me please? Thank you in advance.
-
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.

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.

Awesome! :applause:
I love picking the brains of electronic techs!
I never went to school for any of this.
Yous are better than Bill Nye the Science Guy! haha
Thanks!

I am no tech. I just know what I observe. My only training is intro to technology and youtube.

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?

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
-
Sorry no printer. Unplugged the lights but still have the error. Any ideas? It was working fine before I unplugged it for a year or so.
-
Post a picture of the mpu where the Varta used to be
-
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.

Fixed I merged

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.
-
Here is a pic of the varta battery area. Looks good.
-
Does not look that good at all to me.
Traces look wiped where the board is cleaned to the copper.
My guess is that board is not good and it is very typical that even though it was off for many months the alkali from where the varta used to be still continues it's destruction.

If the problem goes away after letting sit that is a dead giveaway that the sin-in circuit has failed in the post supply.

Could you show me what you mean about the board please? Also do you think changing the board will correct the problem?
-
Look inside the rectangle where the varta was. Copper traces are exposed and almost gone. Board needs repaired or replaced.

Are you talking about the lower right hand corner area?
-
Are you talking about the lower right hand corner area?
Yep. The tiny traces are totally exposed & unprotected in that area...they don't even look continuous. :no:
The battery acid is eating your board alive.
It's time to get another MPU board and swap your chips into it to get this machine working again or pull the plug & sell the cabinet out as a parts only machine.
You can send out the board to be repaired, but by the extensive damage to all the circuit traces, I'm sure it's not going to be an easy repair job nor inexpensive.
Some of these men here can tell you exactly what such a repair job entails, their cost and time but the engine is blown on this puppy.

sturgeon, tried to send you a pm, your box is full.

Does anyone have a spare board you can sell me?

Looks like glare from camera flash.
-
You can see breaks going to u77 in at least two places

Too much glare from camera flash to tell if breaks in traces. What looks like exposed copper is glare.
-
Blow up the very first picture.
No glare ....break in trace

I don’t know what picture your looking at all i see is a hot spot from a flash and crazy bad glare.
-
Same picture your looking at.
-
Same picture your looking at.
And again im saying the fash has made too much glare to say if those traces are bad. We need better pictures. I see maybe one trace that may be bad in your circle but even if that was the case u77 would have to be dead short to cause the board not to boot.
-
Here is another, There are more all over the board it is toast. Yes it's a bad picture but the evidence is there.
Alkali damage all over the board.

I have repaired hundreds of these boards from varta damage the picture is too bad to say either way what you are looking at is glare and artifacts from the camera flash. Varta damage does not leave smooth shiny traces it leaves dull black fuzzy traces with lumps and pits. What does leave smooth shiny looking traces is a later board with glossy silk screen that has had a photo taken of it with a flash. That shine that we are seeing in the pin’s through holes and silk screen would be gone if this board was in as bad of shape as everyone is saying it is. Im not saying there is no varta damping what i am saying is it’s impossible to say yes or no from a picture taken with a flash.
-
We agree that it is hard to tell from the pictures. But I will bet the shiny copper was from someone trying to clean the board with something and that probably did more damage.

Thats not the copper your seeing its a circle of glair around the hot spot from the flash. Could it be hiding damage or exposed copper yes that it not what a cleaned board looks like. Everything is too shiny. Even if it was copper that was sanded down it would not be shiny it would be dull from whatever stripped off the silk screen. That silk screen takes a lot of effort to remove cleanly any method that would remove if from that large if an area would leave very obvious damage to the surrounding area. And if it was varta damage it usually attacks the pins first leaving them green or black not shiny. Literally all i do all day every day is sit at a bench fixing these board. I look at a lot of pictures of boards to try and assess how bad they are. if im saying it’s impossible to say one way or another frome these pictures it’s impossible.
