Not really, no. Tilting the yoke enough in any direction will have an effect though, it absolutely has to. If you moved it and you got nothing, then you didn't go far enough.

It's as far down as it will go. Anymore would snap the neck. It's where it was when I found it. No wedges or support. I had moved it up after I got it but figured I had it too high because my shim was pretty thick.

That sounds wrong. Something was probably messed with before you got there, and the extra color board inside suggests they gave up on it.

I would assume that your set is not supposed to adjust with yoke movement if you're not getting any change. I know there are such designs, but I've not worked on one before. Sorry, I'm not there in person, so I made an assumption that I shouldn't have.

Looking at the pictures of your neck board, there appears to be knobs that relate to the convergence. I think that is where your solution lies. Do your best to document the effect of each knob before you go messing around with them. A good approach is to make a mark on the knob and the PCB so that you can return each one to it's starting position if necessary. Sometimes I will do that with tape so I can remove it when I'm satisfied.

Ok ill check these one at a time after I mark them.

Start with the 3 white shafts that protrude through the board at 12 o'clock, 4 o'clock, and 8 o'clock.

Will do.

Those 3 white one moved convergence around. Looks like that's ok but geometry is a mess.
