OK this was missed by all. If you turn the brite down on any
set the pix should go black or nearly so. Fix this first as it causes
an abnormal load on the HV. Start with a by the book set-up especially
the G-2's & bright limit. Could be just someone set them too
high to get a brighter pix. If not adjustments move to the
vid amp & blanking tubes. I remember NO scenario where the
HV will cause too much brite........
Normally I would start at the sweep then move on BUT the video
is so far off it could be the root of the problem.

The HV adjustment has little to no effect. A strange thing, I can't get the screen to go black. The picture I posted of a blank screen was with the brightness turned all the way down.
