V.F.D PROBLEMS

[vegasbaby]

My s2000 vfd display was not displaying any errors,it was just blank.I checked that i have power to the board.I do.And if i un plug the lower 5 wire plug and leave un plugged,the vfd display will display the following MSG-(DISPLAY PASSES SELF TEST)THEN displays (DISPLAYS NETPLEX IS DOWN)Why would the display only display messages when 5 wire cable to board is un plugged?I have swap ed out boards and both boards and it didn't change anything.What do the experts feel the problem is?Thanks for your help!!

Seen this before.  It is a goofy problem with no diagnostic support.  When your vfd does not work you are blind as a bat.  Unplug net-plex items one at a time and re-boot machine.  start with bill validator,printer etc. depending on your specific type s-2000-regualr, barcrest etc.. Make sure all is hooked up in vfd etc..  You may have a processor problem but I do not think so.  I would start with bill validator first.  Hope this helps,  Barry.  (there is a short somewhere).

Also as a note if you get a newer style vfd you will not need that board that drives the one you have now. B.

What do you mean by "newer style" display?
A 6-6-3 display versus a 5-5-2 display?

I'll drop my .02.  I have had this happen before...not sure why.  All that I know was that disconnecting and reconnecting the cables that you mentioned below didn't do anything for me.  This will sound strange, but power the unit off.  Take out the MPU and reinstall.  If you have a hopper and/or cash box, take them out and reinstall them.  Power the unit back on, then close the door.  Might even try turning the jackpot reset with the key to see if anything changes.

Worst case, use a 97 clear and 31 key chip to reinstall the game using the attached procedure.

Thanks,
Jason

There are vendors here that have the newer style I am sure.  I however DO not think it's your problem, netplex usually starts at vfd (lower) on fire-up and makes it's loop,next usually bill validator,(#1 culprit) since in home use it gets opened/closed alot,printer,bonus items if equipped and etc..  Has this been a working machine for you or you just got/built it?.  B.

Barry, do you think a Automatic Netplex re-scan in I/O options might help?

Why would the display only display messages when 5 wire cable to board is un plugged?

The reason is that the display has it's own self-test before it links to the main computer board....thus why it says "Display passes self-test".

I'll bet you a buck that you have a bad main computer board....I see this problem a couple times a week...change out the board and it's good to go.

Jim,  Your Buck is a good bet.  I was just wondering if this was a project machine or one that just crapped out on fire-up.  B.

HI
This was not a working s2000 for me,but it was almost complete and in very good condition.A while back i bought a used s2000 test station ebay.I took my chances on the test station but for $80.00 was not to big of a leap.The bought a used s2000 cabinet that was almost complete.One thing the person who sold the test station to me was it displayed the same error MSG on the vfd.So it very well could be a bad CPU board.Oh well this just a project for me,with no time line to finish.I do have the last wave of parts showing up Tuesday-TOP BOX AMPLIFIER-MID BOX BALLAST-BELLY BALLAST-DSV 42 SOUND SIMM-MM2 SOUND BOARD.i will get them installed and re post.THANKS FOR ALL YOUR HELP.iF IT IS THE BOARD I WILL NEED NEED TO ORDER.

Since it is a project machine.

Examine the MPU and motherboard for any signs of damage components or traces as well as any bent pins etc.
To gain access to motherboard near botom front of the mpu cover in the machine there is a screw access hole.
Remove the Cabinet I/O cover from the MPU cover so the MPU cover is not stressing those wires.
Remove that screw the cover will slide towards you some and you can remove it.

My S2000, which was a Vision Ready, which was problem child when I first got it. one day I turned it on and it was fine until sometime in 2008
in 2008 it started to develop problems like yours.
I would have credits on it and leave it that way. go to play it, it would chime the credits off, and do nothing. that is when I would look at vfd and it would be blank or say display netplex link down.
I would restart the machine it would be fine for a while and it would happen again.
I found out i had damaged traces on the motherboard near the netplex ports.
A new to me motherboard solved the problem.

HI
Just install new CPU game board,went from a 501 to 504 rev b.I power up and on VFD i  got further than netplex link down.This time it states PLEASE WAIT TESTING MEMORY.Then after 1 min the VFD states Ram error.What is that telling me?Also what i thought was odd was in credits box it read 0.After restarting the zero is gone,but still VFD still reads ram error.What do i need to check next?THANKS FOR ALL AND ANY HELP.MARK

This is normal after a board/game change.  Turn the jackpot reset keyswitch a few times and follow the instructions on the display.  You'll likely get an EEPROM error too, same thing.  After you get those both cleared you should be good to go.

how long was the game shut off for?    i've seen lots of S2000's lose their DC switching power supply during a conversion because the components in the ps cool down and can't fire back up..."netplex link down" message is very common during this situation.

we went through hours of netplex troubleshooting the first time we saw it and just changed the ps as a "why not" approach.  error cleared and game was up and running right away!  good luck 

side note: most of the dc power supplies with this problem can be fixed by replacing the electrolytic caps inside, about 10-15 bucks work of parts is better than a new power supply!
