I think the coarse diagonal bars are shutter bars from the camera taking the video - note they blink out and return suddenly. So, the horizontal frequency may be way off as well as sync being bad.
Check to see if the vertical sync is really off or not by turning the vertical hold back and forth to see if the vertical locks.
