  1. hi I have a sony kv20fv12 wega tv about 2-3 years old.

    the other night it made a quick small kind of "sizzle" noise. The screen
    went dark. sound still there.I changed channels thinking it could have
    been the cable signal. The picture came back for a second, then went
    dark, did that a couple-few times, same thing.
    Turned it off for a few hours
    Turned it back on, all seems ok, good picture and sound,


    Now when it turns on, sometimes I see what I can only describe as a
    sort of arc of rainbow colored light across the screen a bit higher than
    the center,

    and then when turing it off,

    I see a round blob of rainbow colored light about maybe 3-4 inches in
    size at the center of the screen which slowly fades away.

    I never saw it do either one of those things before it made the quick
    little sizzle noise and the screen went dark.

    But anyway, the question is,

    Is the TV set on its way out? Is that the picture tube going bad or
    something else inside maybe minor and cheap, and is it worth even having
    it looked at , or should I run it to death, then just throw it away?

    I thought sony wega was a really good tv

    any opinions helpful

    You will have to have the set properly checked by a service tech. This can
    be a fault in the power supply, or the high voltage. It is also possible
    that there is a protection circuit fault as well. It is not common for a CRT
    to cause the description that are indicating here.

    The tech will take readings and do some basic tests to determine where the
    failure is. This way he or she can give you a proper estimate to service the
    set. From this, you will be able to make an intelligent decision if the set
    is worth servicing or not.

    it doesn't sound like the picture tube itself, but circuitry associated
    with the picture tube. Have it checked by a qualified service technician.
    It sounds almost like somebody wasted some sort of liquid into the set.
