Hello,

i´m owner of a IGT S2000 Barcrest game "DD deluxe with cheese". Now, while doing some settings and switching on the machine, the main fuse at home was triggered. I found out, that it was the power supply that powers the top-box-LED-board that causes the damage. After opened the metal housing of the power supply i found out, that the little glas-fuse inside was broken. So i replaced it with a new one (to be honest: i replaced with a 4 A instead of a 6.3 A). The same: the fuse was damaged and nothing happened. The top-box-LED-board doesn´t lit any more. After that i did the same; replaced a new fuse but disconnected the LED-board. A big blue flash appears at the fuse from the power supply and the fuse blows out again.
Now finally i have ordered a new power supply. But my question: Do you think that i´m right that only the power supply is damaged (my hope) or do you think the LED-board could be damaged too? Is there any way to test the LED-board without power supply if it is still ok?

Thanks a lot for your help and opinions.  :88-

Should be fine.. that's why they put fuses in them so they'll blow (hopefully) before anything else

So, you mean that i could plug the new power supply in when i have got it and everything should be fine? Would be great  :71-
I have looked on the top-box-led-board; there where no signs of smoke or broken parts. Ok, i guess the best thing would be i will simply test it out and hopefully it will work.  :89-

Thanks a lot.

I don't have the schematics for this so I can't say for sure, but It may not be the power supply. Typically a fuse will blow because something AFTER the power supply is drawing too much current. Where did you disconnect the LED board? At the LED board or at the power supply? Because something may be shorted in the wiring harness. Or maybe a stray coin is shorting something out somewhere. Does that part of the power supply power anything else? If you are sure you have disconnected that output of the power supply from everything else and it still blows a fuse, then yes it is probably bad. And no, it should not have damaged the LED board. However depending upon what went bad, it could have sent the wrong voltage to the LED board and cooked it too.

You should be fine.  It's common for the top box power supply to go and likely your only problem.  Many of the Barcrest I've worked on used the "Win-Tact" (manufacturer) power supply which are junk to begin with.  You can replace it with any S2000 power supply that sits behind the reels and you'll be up and running again in no time.  Best to use the one by 3Y-Technologies with the model / customer part number 40009003....they are the most dependable.

I have checked the wiring; i couldn´t see any broken harness or wiring that causes a shortcut or something. Perhaps it was wrong to start the power supply without any ballast to test it? I have read somewhere that you shouldn´t do this...? By the way...Jim, i hope you are right and everything is fine. I have already ordered a power supply via ebay ... and don´t hope it´s from "Win-Tact" again :81-  :96-

Usually the power protection is on the input side of the power supply, so if you have a short on the output side, it will blow the fuse.

I don't know of any power supply that we as consumers would ever run across that would be damaged by powering it up without a load. I'm sure there might be the odd industrial power supply that could have this issue.
