Be sure to read this before working on boards:

Yea I tried pushing on the roms and the board while it was on. When I pressed around one of the roms the flashing x's on the screen turned to 0's. It stayed that way and I could not recreate it again. I reseated the roms and they are all in good. Nothing I did poking around with all the wiring seemed to have any effect. I will try soldering a wire onto the pcb and running it down into below the playfield somewhere where I can find a ground and see if that does anything. I guess it is acting like there is a missing ground or something.

Check your door.. there is a slam switch that may be open... I recommend doing a slam-mod... or solder the slam switch wires together..

I am pretty sure I read somewhere that bad girls and a few others actually come with the door slam switch shut but I may be wrong.

True... but if that closed switch isn't making a good connection it would do the 0000000000000's on the screens. The reason why I recommended soldering the two wires together on the switch.

Ohhhh, i watched the beginning of your youtube video and you scare me.
you really need to take head of what KEN LAYTON keeps referencing about the repair guides.

and i'd suggest getting the dvd's from shaggy that talk about pinball restoration in a fun yet informative way.

sounds like you are VERY FAR from the point where you are messing with the boards.

start with something simple, like touching up the grounds on the light sockets with some solder. which will get you started on using a soldering gun without hurting anything due to over heating......

and here is where you really need to go to get basic troubleshooting theory that starts with the difference between a resistor and diode, etc.

Russ Jensen. The guy is brilliant and wrote in simple layman's manner.
See his t-shooting repair guides and start with 1 and go up.

Is this the part that has two metal contacts that are springy?

I guess you are talking about how I unplugged the connection with it on? Yea I didn't know you couldn't' do that. I am trying trying to troubleshoot with a multimeter. I will check it when I get home. If I find out it is the cpu board I have someone who can fix it. I am just trying to keep the cost down of having to pay someone to come out to my house house to tell me its the cpu and than leave with the cpu and I have to pay there travel time to my house (2 hours) I will read those guides that you linked. Thanks.

Just tested the c1 diode on the cpu board. It is showing 4.6 volts so it seems the board is getting enough power.

Did you get this working yet? Hope so.

Dial that up to 5.10....
