SOURCE: vertical hold problem
There is a fault in either the input video amp, sync amp, sync separator, or the vertical scan generator areas. Most of the time this type of failure is caused by capacitors in these areas going off spec from age and use.
An experienced TV tech who is familiar with your set should be able to service this for you.

You better take this fellow to a doctor. You have a stamp size IC with about 250 pins that is bad. Only a tech can replace this or reinstall a remanufactured board into this TV. You may ask the tech to use a freeze spray to find this IC first and then he wil decide how to operate!l
