Tried the card trick before...good thing to use it also for scheimpflug...
Is there also a way to adjust the red and blue tube/pattern with the basics as it is for green...skew, bow, etc?
I am used to the sony and this was possible....or is the only option to adjust R/B in the "dirty" way by conv to green (dont like this since the coarse adjustments that are needed at the start are too large to just compensate this with the subtel zone conv)

you can adjust red/blue vertical size in the service menu and the red/blue width size with the slugs on the HDM. once you've done that and toe'd in properly, you'll be driving the convergence less when matching to green.
it's a shame that the marquee's don't have individual geometry control for each colour.
EDIT: forgot to add, need to rotate scan yokes to make sure red/blue are level to green also, and to adjust focus coil so that everything is close to centered in relation to green. if you do all the above correctly, you should find that convergence adjustments are minimal. start with interpolated then finish with guided convergence modes.
also, make sure to do all these adjustments with convergence nulled.

Ah thx, so no individual Geom Cont for R/B (can't have it all)
The tube aligment is nearly perfect now H and V 
Edit: Can't find a way to shift the total pattern (R+G+B) when displaying the internal testpattern (in the guide it's a matter of using the arrows on the remote...so the function must be there....and phase is only for the source/external signal right?)

First shift using your focus yokes.
Electronically, to shift green, use green convergence in the convergence service menu.
Use guided convergence at centre only to shift red or blue.

Am I wrong that with the green the red is always present and that the red is shifted in that case? I missed the green only convergence (or is it possible to switch red off?)

You need to go in to Convergence service mode, then you get green convergence. From here you can tweak your geometry to perfection also. This mode has no influence on red/blue.

If you find what the password is for the service menu, let me know

Thanks, it works on my Vision 1 
This gives some more focus options for each colour and also the astig

0901 is correct

The options are excellent compared to a 1272

Next is to align the tubes, Reinier told me about the 2 screws near the lenses but I also have to align the center of red and blue on green.
In my topic you can see what a mess it is rightnow 
Resetting in the service menu made it some better but centering is a mechanical thing.
I think the screws on the bottom of the tube housings should be adjusted.
