I have 2 power supply's, both the same make and model that are totally dead, not even the machines florecent bulbs will light up. I inspected both power supply's and don't see and bulging caps or any leaking. The fuse in both check good on my VOM. The only thing I see is brown staining on the inside of the cover from my guess is heat. Can anyone give me an idea of what to check? Being totally deadly seems strange? I would think the florescent bulbs would light being 115V.

have you checked the solder joints under the board. i have had a few power supply's that the transformers had bad solder joints.
-
No I have not.. I will check them and the others.

Also just because the caps dont look bad doesn't mean they haven't leaked. I usually use an esr meter but they can give fauls readings. I haven't tested it yet but i have heard you can black light boards to check for cap leakage or heat damage in pcbs. It may only work on some types of board.

The S2000 uses electronic DC ballasts that operate off of the +25VDC supply. The ballasts in turn provide the power to light the tubes

I understand the 25v powers the lights, but my question is what would cause the whole power supply to be dead? The main fuse is good, i removed it and checked it with my meter.. Does this point to a certain bad cap, or a transformer? if I had a schematic of the power supply, then I could follow the input flow..

There's at least three different versions of power supplies for the S2000 (and GK/I-game too). Not sure what model you have there, but here's schematics for 3y and Autec power supplies.

That's a 3Y pwr supply. You can order a cap kit from Suzzo that will replace all but 1 cap. has a 90% success rate I find.

Bad think with Suzzo Happ is the $100 min order amount!! I can buy 3 power supply's for that same $100..

Looks like the power supply has a couple of line voltage filters, that might be something to check. On older slot machines that had a line filter module (where the a/c power cord connected to them) that used to be a problem sometimes and people would just bypass them.
