The LED Circuit Board has one Power In Port (A), and four Power Out Ports (B).

Port A has become loose, and no longer allows a good connection.
Is there a sensible way to stabilize Port A?  Woodland does not have a replacement board.

I was thinking about simply cutting off the 5 plastic connectors and splicing the applicable wires together.

Your description can be interpreted to mean either a bad electrical connection, bad physical connection, or both.  The problem could possibly be caused by a few things.

When you say the Power In Port is "loose", do you mean:

A) the port itself wiggles on the circuit board

or

B) the plug that goes into the input port doesn't stay securely?

Also, have you tried using a different input power cable?

Thanks Steve.

The port itself wiggles on the board.  I am able to find the sweet spot and jam some paper in to hold it in place.  But I really am not happy doing that  

I have tried a different input power cable with the same result  

Sounds like a broken or cold solder joint where the input power jack attaches to the PCB.  This can likely be repaired by re soldering the two connections.

I had considered that, but abandoned the idea when I couldn’t see where to apply solder.  I’ll take another look.
Thanks.

The solder is likely on the on the back side of the PCB; opposite side from the jack.  Feel free to post a picture or two...

Steve is correct.   This should be an easy fix.  Remove the circuit board mounting screws and flip it over.  Touch your soldering iron to each of the 2 pins in question where they poke through the board (along right side of photo).  Hold it til the solder flows then remove the iron.  

This board is from the Woodland Scenics Smith Bros building, but it should be the same or similar.

Thanks guy.   Success.
