CEI Poker machine 327-510

Hi there.  I just picked up a CEI poker machine.   The model # is 327-510.  The main board had a dead battery so I replaced it.   When I turn on the machine, the CRT comes on but nothing is displayed.   I did find a loose wire in the cabinet.   Can anyone tell me what it is supposed to connect to and if it could be the problem?   Thanks!

Neither of those is related to it not booting correctly. I believe that is an old style connection for progressive machines.
If I had to guess your main board is not getting power from the power distribution board that is shown. I would re-seat all of those connectors, they get oxidation really bad. Deoxit if you have some.
If the computer still wont reboot you might need to do a processor reset, but only if you are comfortable working with components.
Gently pry and remove the processor chip from its socket.  Short all the legs on a small piece of aluminum foil. Replace, and restart. I know it sounds a little primitive. I had one of these and had to reset it a few times until I found the bad connector that was causing the lockouts.
Also, Im not sure if your machine needs a battery. If you have time post a picture of the machine, and computer board.

Thanks for the feedback,  here are a few more pictures.   I have replaced the battery on the mainboard and it is secure.   I will look at reseating all of the connectors in the machine as a next step.

Remove all socketed chips and clean their leads with an eraser, if the sockets pins are not shiny spray a small amount of DeOxit on the pins, let set for 10 minutes, then blow them dry before you plug the IC back in.

Thank you for the feedback.  I have tried removing all socketed chips and all pins are shiny.  I have placed them all on a metal surface for several minutes and then put them back in.  However, the machine still will not boot.  Any further ideas?  Would it be helpful if I share a video of the power up?  The screen comes up with faint horizontal lines for a few seconds and then nothing is displayed.  It is just sort of dark grey.
