The problem is vertical failure. Vertical output section to your TV ahs the fault. You ahve to check the vertcial output circuit for any component failure or loose solderings.
It sounds as if the color controller/circuit board is becoming sensitive and may soon disconnect. Don't be surprised if someday soon, the picture goes very dark or vanishes completely. Have a technician check it out with his test equipment to locate the exact problem.
