OK so quick question about this TV, is the brightness and contrast controls supposed to affect the focus circuit of the TV?

I'm asking because whenever I adjust the brightness and contrast controls on the TV the screen's focus adjustments go haywire in that the screen's focus centering goes way out of whack like instead of the picture being correctly centered in the picture tube it goes way off to the right hand side of the screen and produces a large shadow on the left hand side of the screen and then the screen goes black until you turn the brightness and contrast controls almost all the way to the bottom to the point that the image is barely visable on the screen, any higher than that then I get scanslines on the screen and too high the screen goes completely black.

any ideas as to why or what would be causing this issue?

Its only been doing this since I relocated the picture tube back to its "original" position in the chassis from where I had it previously where it was providing an excellent picture and just needed its vertical size and linearity readjusted to the appropriate size for the shadow mask behind the safety glass in the cabinet.
