Definitely check the jones plug that provides power - I think it's in the front left side of the cabinet. I actually fixed this exact problem on an Old Chicago a few months ago. The pin on the plug had completely burned up and wasn't making contact.

Quoted from xsvtoys:

Then move that lead over to the other side of each 6V fuse, you should also see the 6VAC there as well. This will tell you its getting through the fuses OK.

After making sure voltage is getting through the fuses, follow each line up to the top of the Jones plug (Blue and Brown wires, 2nd spots down on the connector if I'm looking at the pictures correctly) and confirm you have voltage there as well. If so, continue tracing those wires to the next connector in the bottom that goes to the playfield. Then go up to the playfield itself. The Bally plugs often break or just don't making good contact.
