This is usually caused by some of the electrolytic capacitors in the vertical deflection amplifier and in the blanking circuit areas. Sometimes it can be some of the other types of components going slightly off specs.
To test the capacitors, an ESR meter or the equivelent is required.
I would suggest sending the TV out to have an experienced TV service tech do this type of work for you. These types of problems can get very involved. There are also some serious safety issues when working on a TV set.
