best thing is to can you show some pictures,
some for the overview,and some detail from the board.
Dit you take care of electrostatic during swapping the port,
means have a electronic workingbench or at least you and the table and the boards have to be grounded before you start your work?
If you didnt, its a strong possibility to damaged booth boards(old and new).
Are there some jumpers or switches on the port?
How does the connector goes on the board, smoothly or a lttle hard?
Is there a chance that a pin maybe is bented ?
Disconnect at look for the plugs or inside the connector.
What you mean with a slight bend in the frame?

Dit you look at the revision nummer of the board and the date?

I dit personally change from MK1 to MK2 with the 5k and the 5.5 k.
Everything running smooth after that,
but you have to have electronic experiences for that.
Also i dit take out the control(DSP) board on the 8k,
as i had sometimes some cracking noise in the chassis.
Finally M replaced then the board on the 8k, checked the whole electronic chassis and changed one power amplifier.
