dansoftcore:
I have a 1985 williams sorcerer machine and it did work nice until about 2 years ago.  While it has been collecting dust I decided I'd look into fixing it now. my only problem is none of the diagnostic switches work or do anything.  When I turn it on and look at the cpu boards indication light has a 7 on it and the only problem cause I have is cpu board lockup or pia u5 faulty... Before it kicked the bucket it did have a problem blowing fuses but I wasn't the one working on it so I don't know what fuses were being blown.  Does anyone have any pointers suggestions or can point me in the right direction?

dansoftcore:
I wasn't aware of any other buttons on the cpu board other then the two diagnostic buttons sw1 and sw2 I did replace all three double a's tho.

dansoftcore:
seeing that it is probably the power supply is it better to just replace it or fix it? The cheapest replacement I can find online is 100 bucks...  Id like to fix it but I don't see anything wrong with it everything is putting out what it should and I replaced all the fuses =\

Jeff AMN:
You should always try to fix things first. It's not so much about the money, but the experience you gain will help you identify other problems down the line much faster. If you learn early on how to fix your machines, you'll also be able to score better deals on machines because you can buy machines with issues at a discount. But yes, fixing is cheaper and if you learn how to fix stuff, in the long run you'll be less frustrated by the expenses this hobby can bring.

Ok, so it is about cost too.  ;D

dansoftcore:
Ahhh I'm not worried about scoring better deals since I live in an apartment and I don't have much room for more then two machines and the people bellow me probably hate my guts! Just this pin and a mame cabinet I'm currently working on!  The pinball was a present from my parents about 5 years ago the thing ran fine with very basic maintenance until it started blowing fuses the just wouldn't come on.  So I have never repaired a machine before but I do have background in electronic board repairs so I thought it wouldn't be so bad to tag a stab at it myself before ordering the part. But as of now I'm completely confused about what to do next I know its a pretty basic board that they used in dozens of other william machines so I'm really hoping one of you nice folks can share your wisdom with me!
