Well, without running some tests... My guess is that you have no voltage to the displays. (source voltage and fuse is on SOL DRV BRD).
AND you have a shorted driver transistor for the knocker. (ALSO on SOL. driver board.)

For now, just remove the smaller wire on the knocker coil so it does not lock on.

Now, you can power the game on and troubleshoot the missing displays. You will need a voltmeter to test for the proper display voltages at the driver board and at the displays...

If you are not comfortable doing that with a voltmeter, then a known working driver board will tell you more about the situation... In other words, if a known working driver board resolves the two symptoms, you at least know what is wrong with that board, moving forward.

Mr/Ms is such a great game. Get that thing flipping!
