So had some boards worked on in my Mr and Mrs Pacman pinball. Put them back in. Boots but some issues.

No displays at all. Nothing. Also if J2 is connected on the solenoid driver board then the knocker coil stays engaged all the time.

What is my problem here?

Should I just get a known working solenoid driver board? This board was not worked on...

Previously the game was working with sound issues... The sound is fixed now...

The displays and coils normally do not share data information. It sounds like a pin on the j4 connector is shorted or miswired?
Inspect J4 and J2 on the sol driver board. Look for a short or a misswire.

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!
