got a wms 400 non dot . what the problem is that there is no display, credit, or otherwise when you turn it on , you get the b/v to run and you get 1 bong reel lock up but dont spin , i put a good working lower p/s in and it does the same thing , i changed the cpu and i/o boards same thing im getting all the correct voltage to the i/o board so i know that is all working , i tried to run clear i get the bling sound, but no display so i cant see whats going on , so i know my p/s is good , i even swapped it with a good atx and harness from another 400 machine i had long ago , and i know my boards are good , anyone ever run into this before. i dont have any other parts for this machine , backplane board go bad
or just bad display, before i start taking the harness apart was hoping someone might have had this happen to them before
