Title: WMS Jackpot Stampede Deluxe - not playing after startup
Post by: pathfinder2072 on April 25, 2020, 07:07:02 PM
Hello.  New to this forum and slots in general.  Great site btw.
I recently picked up a Williams Jackpot Stampede Deluxe and have the following scenario:1-Unit powers on2-Does a ROM check3-Displays Williams logo for about one minute, then dot screen goes blank.
A) No "bong" at startup (although, there might be no sound at all)B) No fail light on I/O board, but only far left and far right LED's are litC) There appears to be no power to coin, Bill, Hopper, front buttons, lower lcd displays or reels
I don't seem to be missing any boards, but cannot be certain
Steps Taken so far:1) cleaned and verified seating of all connectors and IC chips2) found weakness in upper power supply so did the ATX replacement (great procedure, made it easy)
I do have some experience with arcade coin ops, but this has me stumped.
Any help/guidance would be appreciated.
Thanks!

I believe your lower power supply is bad.  You can do the same  ATX conversion to the lower PS. There's details for that as well.

Completed the ATX procedure.

Works now all the way.
Thanks!
