Sony KV-20FS100 problem.

    I have a Sony KV-20FS100 television. The TV is less than 3 years old
    and has been very lightly used. One day, while watching, it simply shut
    off (as if someone pulled the power cord). Pushing the power button now
    has the following effect: relay inside TV clicks, tube sounds like it
    is powering up, but nothing ever shows on the screen, and immediately
    it shuts back off again. The red POWER LED will continue blinking for a
    few seconds, but then nothing. I pulled the back cover off, looking for
    anything burnt up or obviously broken, and even went over the circuit
    boards with a magnifying glass. Can't find any toasted components or
    bad solder joints. Any hope for this puppy? All the local TV repair
    shops have long disappeared.

    Call Sony for the nearest authorized servicer. They will have the
    training and service manuals on hand for a model this new. Then check
    references on those names they give you.

    Unless you know of a good independent, non-manufacture affiliated,
    repair shop (by references or past experience), it is usually best to
    take a newer item to an authorized servicer.

    Without a complete internal diagnosis, there is no way to know if it is
    worth fixing.

    FYI most of the big box stores will take stuff in for repair, but they
    truck the items off, pay $8.00 for most of the 'techs' they have
    employed. They are in the business to sell you something new, rather
    than fix it.

    Suspect power supply and possible deflecteion related failures. Probable due
    to poor solder connection s in the horiz dirve and output sections. Nominal
    repair may reun Apx $150 -250 pending on the facility and their respective
    rates. As recommended, choose an shop that either is SONY authorized or one
    that has lots of experience on thier products.<>
    FYI: If there is a C/C store in your area they do COD, via their service
    division, and are SONY Authorized Service with manufacturer data and
    contact.
