SOURCE: vertical output problem
you probably just need to resolder the vertical output IC. It will be mounted on a heat sinc. probably 7-10 pins. Part number may start with "LA" like LA7845 or similar, there are others though. You will probably see the rings around the solder joints on the bottom of the board. Good Luck

Hi. this is caused by dry solder joints on the frame o/p IC. Resolder all legs of frame chip. Should sort that out.
SOURCE: horiznal line across screen
The picture tube itself is not longer being manufactured and the replacement might exceed the price of a new TV.
The vertical line you see on the picture tube is not a failure with the picture tube but a different part inside the circuitry.

go to the vertical section n change caps like 100uf, 2.2uf around the section in addtion check some caps in the line o/put like 22uf 250v
