Make sure all the connectors are correctly placed. Are you sating that the TILT light is lit when you turn it on? If so, check the slam switches and the roll tilt are not stuck. The roll tilt is a ball in a guide lane on the right front side of the cabinet. There are a few slam tilt switches - look for any big (long) switches that have a counterweight at the end of the leaf switch and make sure none of those are making contact.
I assume you can start a game since you know the flippers work. Does it score points if you knock down the drop targets or engage any of the rollover switches?
I thought there was a solenoid fuse under the playfield, but I opened mine and don't see one. It's probably one of the fuses at the bottom that you checked.
