I've monkeyed with the mechanical focus coil adjustments for 4 hours and unfortunately I can't get the corner cut-off to disappear, when I get it to disappear on one corner it just reappears on another corner, and vise-versa.

Vertical not filled and non-linear: put a test pattern (in a pinch end credits with even spacing between lines when viewed on a better set will do) on screen and adjust vertical height and linearity simultaneously (may need to juggle vertical centering too)...If you can't get a full linear vertical sweep check resistors I the vertical.
The vertical I can't seem to get it to fill properly, I either gett a stretched image at the top of the picture and a normal picture at the bottom and or not enough fill at the bottom and too much fill at the top, and this TV doesn't have vertical centering adjustments that I can see of.

The left vertical lines are probably horizontal drive lines...try adjusting horizontal drive...If that don't do it your probably going to need to adjust the horizontal osc waveform with an oscilloscope.
The vertical bars on the left side of the screen were indeed horizontal drive lines, I readjusted the horizontal drive adjustment and the bars went away.

But now I can't get the screen to fill out horizontally, for some reason or another I can't get the horizontal linearity and Horizontal Size adjustments to do anything to the screen as far as resizing it goes.
