Also, the neck socket can be broken inside the socket, so the pins can appear ok, but the break is inside where you can't see it without breaking the socket open.

This has happened for a few folks here, but it's been the screen pin (or is it focus, I forget), which is the single one that's set apart from the others.
 
Well, swapping the neck board with another brought the K6100 back to life! Looks like there is some failure on the neck board itself. I will need to go over it with a fine tooth comb to look for any breaks, socket issues as you suggested, etc. It's actually a pretty clean neck board. Thanks for the guidance and reassurances. A weird one for me.

Now to tackle that other fully rebuilt HV unit that appears to be bad.

Make sure you aren't missing any of the ground wires on the neck board. There should be two (gray and black) that should go down to the aluminum frame plate. The black one often falls off, and they both weaken, so it's worth stripping and resoldering them both. I zip tie them together (and to the other wires on the nackboard), to add some mechanical support.

Same goes with all of the wires, pretty much. They're all prone to hanging by a thread.

Yes, I definitely confirmed those two wires (black and gray) were screwed to the frame, both on the bad neck board, as well as the good.

I swapped the rebuilt, but known, HV unit back onto this previously unknown K6100, and after tweaking the HV "Screen" a bit, it now works too. Admittedly, the blue was almost entirely missing (it could seen when the HV "Screen" was turned way up), but a little nudge of the neck board towards the socket fixed that issue (I already did that x2 prior to powering-up). Maybe the neck board sockets are just not getting a good seal on the tube neck pins. The convergence is a little off, mostly blue, so time to break-out the manual to fix that. :)

I agree with your thinking about the various wires coming from the neck board. Piss poor design INMO, but it is what it is now. My normal SOP is to test and resolder those during a rebuid, so that is probably not the issue on the bad neck board.

From being a totally dead, unknown condition, with missing parts, to a fully working... I'll take it! :)

Does it need a spring or couldn't you just attach unshielded wire to the back of the tube and run it back to the neckboard?

The spring is there to ensure contact at all times. Unless you can be sure the wire is in constant contact, then you're taking a chance.
