Where is this all famous StephenH? Hah well I replaced all the fuses checked the two leads 12v and 4v I think? And everything seemed fine this is just so bizarre. I'm off work tommarow so I mite mite try hooking up the power supply to the board and seeing if it turns out without a 7 error. Should I unplug all the other cables from the cpu board before I try that?
dansoftcore:
Thanks I didn't think of that i'll try that out tommarow. I'll have to find some schematics online it didn't come with any =\
dansoftcore:
So after messing with those plugs its still giving me the 7 error but it seems like if I have any one not plugged in the 7 won't be there and it will be a 0 but I can't actually do anything with the diagnostic buttons or the auto up and such. When it wasn't doing the 7 error it was flickering the lights really fast and then making the da ding noise for a free game and then the 7 would come up. This is really bizarre and I'm thinking I mite have a big project on my hands now=\

Sounds like you have some reading to do:

Print out the guide, and read it through. You'll learn a ton of stuff, and fix your game.
While you're at it, print this one too:
