Question

Help answer this question below.

I have a symphonic 27" television only two years old. A month ago it started showing horizontal lines, bright white, three inches from the top. Now, it still has the lines, but it has shrunk the picture as if the shows are not formated for the tv. Thanks

    The vertical output IC is operated from a scan driven power supply. these supplies, while efficient, run at high frequency. Thus, the filter capacitors tend to run hot when their ESR changes. This is not at all an uncommon problem to TV repair professionals.
    The simple solution is to resolder the output IC itself, and change the power supply capacitor - or capacitors, and the problem will go away, parts will cost about a couple bucks.

    I'm looking for a similar answer. I have a four year old Panasonic doing the same thing. White lines started appearing until they reached about 1/5 of the way down the screen. After a while, when powered on, the screen stayed black and there is a horrible high pitched sound.
    I am using a 1985 13" TV temporarily and it got the lines at the top then the picture turned black at the top third and lower third. Next time I turned it on the top half has a picture but there is a super bright white bar across the bottom portion of the picture.
