Question about Televison & Video
This kind of symptoms is an indication of fault either the Y-sustain or Z-sustain board. Based on the symptoms you've mentioned, there's an instances that the vertical lines appeared on the right side of the screen, I've suspected that the fault came from the Z-sustain board. Replaced this board and its buffer board.

Since the lines are vertical, the image is lost sideways and the corruption changes with the image then clearly this is a sign of Y-Sus failure, not the Z-Sus or the buffer boards.
An logic or input board failure would affect the entire screen, not just a part of it and a failure in one of the buffer boards would affect strictly defined lines of pixels and the defect would be constantly there all the time.
Since you haven't told us the exact model i can't point you to a replacement board.
