    Someone gave me a rather nice tv. It's been years since I worked on a
    tv. It has a horizontal line across the screen, but wont expand to
    cover the screen. Is this a horizontal or vertical problem. That
    always confuses me.

    Thanks

    Vertical.
    Your vertical oscillator is dead.
    In most TVs, the vertical output is *part* of the vertical oscillator;
    so replacing the tube/transistor/circuit that is *called* the vertical
    oscillator may or may-not fix the problem.

    In any case, likely it will cost more to fix or replace the ailing
    vertical circuit than the price of the TV.

    Even more-so for the Horizontal section these days. If that was dead,
    then you wouldn't even have the line.

    If you had reduced-height, not just *no* vertical, then the likely
    culprit would be a bad capacitor. As it is, it's likely to be an active
    component.

    I fixed one of my TVs last year with the same symptom as the OP (horizontal
    line), and the fix was indeed a bad cap in the vertical section.
