Hi.

It is probably a defective ballast board or a faulty PSU. The ballast is the high voltage power board connected to the lamp.The PSU is the board that supplies power in different voltages to the other internal parts. One of the DC lines from PSU goes straight to the ballast. The repair is done testing the voltage from PSU to ballast. The job must be done by a technician.

Black line problems


Some components in the vertical deflection amp have been going out of spec with age.

The set may no longer be worth to spend money to service it because of its age. However, if you wanted to invest the money, the set is serviceable. Considering its age, the CRT may be soft, and there are many other older components that can soon fail.

I would be considering a new set.

JVC TV 27" Black line on top of screen


This is for the original problem.. Not the second post.

It's a problem in the horizontal deflection circuit. The parts will be available, but you will be in for some daignostic repairs also to find out why it failing or if it has failed on it's own.
There should be a few caps near the IC (an LA7840) that could also be causing the problem. Click the link, it will make it easier to locate the part inside.

This is the kind of repair best left to a TV tech, but get it done now and it won't cost anywhere near as much as it will later.
