Sony PVM-14N5E with a multitude of problems

A while ago, I found this monitor for somewhat cheap knowing that it had a green tint, black horizontal shadows on the right of the OSD text and somewhat pinkish whites. These problems can be attributed to worn out tubes, but I made a bet that these could mostly be fixed with service menu fiddling and G2 adjustment, and thus bought it.

Sadly, while the G2 voltage was indeed a bit too high, reducing it did not remove the shadows nor the green tint. I found out that the green tint was only present on shades of grey, and horizontal shadows appeared besides anything colored white. With certain values of brightness, G2 voltage and service menu settings, the horizontal shadows turned from black to green.

Also, there seems to be a problem with the green gun or something related to it. I had to really crank up the green cutoff/drive for the whites to look somewhat decent, and there were other issues like the green discoloration and a white contour on the sides of some objects, both can be found in the photos attached. Red and blue colors display no such issues.

Do you think the green tint can be fixed, or is the tube a lost cause? I have no hope of getting rid of the horizontal shadows, as they seem to be a telltale sign of tube wear, but the tint looks like it might be a capacitor problem (I have another CRT which has problems displaying a very specific shade of grey correctly), at this point even that would be good enough for me. Would really appreciate to hear your opinions on my situation.
