    My Sony Trinitron has lines across the top 1/4 of the screen. It looks as
    though you are viewing that portion through rippled glass. Can anyone tell
    me what is wrong?
    Thanks a lot.

  2. Probably bad capacitor(s) in the vertical circuit - though this is less
    common on Sony than some other brands.

    The specific symptom you state may be caused by a "boost" capacitor being
    bad. If so, the vertical output IC is running really HOT and will fail.

    Also, there is a chance of burning the tube at the top where the lines are.
    This is permanent damage.

    so DON'T USE THE SET in this condition . Get it fixed. Or replace it, your
    choice.
