One caution. The service adjustments ( h-freq, V-lin, V-size ) are
very small & delicate. They also have lock tight on them often.
SO go very easy on them !
Sounds like the electrolytic caps are bad in both the Hoz & Vert.
It could also be just a dirty tuner.
BTW the fine tune is multy turn. Could be that is way off.
When you see the pix try turning it 1-2 turns CW & see what happens.
Sometimes you also need to push it in too to engage the gears.

May have made the mistake of fiddling with the knobs too much to begin with so I'm kind of starting with a clean slate. The Horizontal and Vertical knobs both mess with the wobbliness of the screen (the alignment?). I can get the screen almost centered then it just goes out of wack. I turned both of the knobs so that they're at the center location because that seems like roughly where the center point is. I go to adjust the horizontal frequency and I can almost get it just right but not quite.
The best I can get is the screen being slanted. I've adjusted it multiple times and the slant is always in the same direction too.

Here's a video of my fiddling with stuff so you guys can see what I'm talking about. I don't know if it's all a problem with the TV or some stuff needs to be replaced. The knobs are unbelievably sensitive to touch. Sometimes just removing the screwdriver that I am using to turn them is enough to make the image more messed up.
