A blurry bright vertical line near the middle of the picture may be due to a horizontal drive issue. Does the set have an adjustable horizontal drive coil? How about a horizontal linearity coil?

Sadly no, I looked all over the chassis and the set as a whole. Then I reviewed the sam's photofact for the tv and it appears to not have any horizontal drive or horizontal linearity controls. Why would a tv omit an important control like this? I am assuming to cut costs? lol

Everything goes into that decision. Saves $$ & often not needed. There is an
old Zenith ad with a mayonnais jar full of parts. They were not needed
for the TV to work under "normal" conditions. Thats why a Zenith 12"
costed $30 to $40 12" GE.
For your drive line look at the hoz osc & output tubes first.
BTW old Zenith B&W's had a width sleeve a.k.a lin sleeve. its between the yoke & CRT neck. Pulling it back will widen the pix but is NOT your problem.
Often its missing, a lazy tech would just throw it away for more width.

OOPS
I meant the GE was about $80 vs Zenith $120 for a 12" B&W.
