Vertical or frame rolling indicates adjustment of the frame hold is required or perhaps there is a synchronisation fault.
Breaking of the picture in the horizontal plane is caused by the line hold requiring adjustment though the symptom can be connected with interior or exterior signal problems or perhaps a power supply fault, especially where both the line and frame are affected together.
It is probably a task for an engineer or at least someone with access to the servicing instructions.
That is not a vertical roll from side to side, this is a horizontal rolling. if the vertical had a roll it would be going from top to bottom. This is most likely a coupling between the horizontal sync circuit and the sync separator circuit. Good Luck
is this a horizontal black line going up or down? if yes, this sympton is caused by a trouble in the integrated circuit or in the vertical oscillator circuit.
this symptons has 2 variations. one is the intermittent rolling of the picture. this referred to as the "loose vertical hold" the other variations is the continuous upward or downward rolling of the picture
