I'm not seeing any dark vertical bands at all. Are you referring to the test pattern image a few posts above?
Sure looks to me that there is sufficient width and the squares on the far right are not quite as wide as those on the far left.
That's why I keep saying it's a linearity issue and you need to adjust the drive/linearity/width controls.
Don't mess with anything under that metal shield. Those parts have nothing to do with centering the image.
Also, why are you trying to get the picture tube out?
