  1. Hi,

    I have a JVC AV-21TS2EK TV that has developed a fault. A few minutes after
    power-on, the picture becomes very liney, and disappears to the bottom half
    of the screen.
    Constant pressure on the top back left of the TV stops it happening! Any
    ideas?

    Thanks in advance

    maybe the poweramplifier for the vertikal deflection is defektive.

  3. ESR the caps in the vertical deflection and supply circuits, also may
    require the vertical output ic.

    Suspect cold/bad, solder joints, in the vertical area. Well worth taking to
    your set to a shop for an estimate.

    Looks like a dry joint on the field output chip. Have a good look with
    a magnifying glass.
