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.
