That's an interesting picture. Your horizontal oscillator is 100 miles off from where it should be. There also appears to be a sync issue, and about 2/3 of your vertical is compressed into a band at the top.
The horizontal is either half, or double of the normal horizontal frequency in the first video.
Has the horizontal hold control slug been turned way to the bottom or the top?
Try adjusting the H hold control from one extreme to another.
Has the set been recapped?
What work has been done to it?
