This is a vertical circuit problem. The bumping tells me a solder connection/s on the output ic are broken loose or poorly soldered.
It is a chip (I will attach a photo of a typical chip--yours will not be exactly like it but you should be able to locate it).
The part in the photo has the generic number (LA...... which is one designed by Sanyo but used in many different sets) The chip will usually have between 7 and 13 pins.
All someone has to do (unplug set and remove cover) is take it apart, gain access to the main board (it may slide out or if open view of the bottom just turn set on its side after you locate the part---part should be fairly easy to find as it is always bolted to a small metal plate to cool it.
Take a good look at the pins from the bottom and resolder all of them.

This is a problem with the vertical output signal. Check the vertical coupling capacitor, the vertical output between the yoke transformer and the vertical output transistor amplifier or (IC output). My odds are on the coupling capacitor being bad.
You will need a schematic diagram and an oscilloscope to check this problem. If you have a background in electronics you will have no problem solving this problem, however if you do not have a background in electronics, I would suggest getting a qualified TV repair technician to do the work on your TV set.
