Pinball 2000 need some info

so I picked up this pin 2000 revenge from mars machine a few days ago, got it home... plugged it in, turned it on and... nothing
power supply fan not turning. removed pc case, removed power supply and it's cover to find leaky cap.
ordered new power supply and new cpu fan... installed both today, thought woo hoo we gonna play some RFM... not.

took some pics... take a look
when I flip the power switch I hear the speakers and the monitor come on, have lights on the computer box, prism card, control bard under pf, and in the main box under the pf. any help would be appreciated, also have light in the tube... see photos

noticed the "health" light is not lit on the cabinet board

it was free didn't check it

i literally saved 4 video game cabinets and 2 pinball machines from the sledge hammer and dumpster... the lethal weapon 3 works but needs work... stuff on the way for that one as well... thought maybe the power supply and cpu fan was all this one might need

caps looked fine... and I guess if nothing is coming through the mother board then the pinball machine wont do anything at all? I have nothing going on the play field at all

A good friend of mine, his grandfather worked in the industry for about 50 years... he still has machines on route. He is in the hospital, and not looking good that he is coming home and is headed to assisted living. My friends mom wanted everything out of the house and his workshop, so she told him to get a sledge hammer break the sides and backs off of everything and throw it in the dumpster she had rented. He called me and asked if I would want this stuff... machines, boards, power supplies, locks, bulbs, fuses... basically this guys whole operation at the house... I said how much? his mom said you get the ms pac man going and you can have it all... well, the ms pac man is up and running, delivering it back to her friday... so I'm trying to get these two pins good, so I can play

will pick up a usb to serial adapter tomorrow and try to connect to it
