I have heard that magnetic field makes irregular fields on crt screen.
In my case there is one 10 cm wide line from top to bottom. Regular.
I rather doubt it's a magnetic field problem. A distinct sharp edged
artifact like a vertical line is normally associated with an electronic
problem, possibly a bad cap. Or, possibly something simpler like a black
level adjustment. You may be seeing the sync signal feeding through to
the video somehow.
If it were a vertical band at one edge I'd nod to that, but in the
middle? I'm just plain puzzled on that one.
The horizontal sync pulse is more or less in the middle of retrace.
