    My Sony TV (model KV-X2973B - AE2A Chassis) front led is blinking.

    No picture and no sound.

    I think it's the tuner. but not sure.

    Thanks for your help

    Also post how many times the led flashes, it does make a difference in
  4. If the LED is blinking at a steady or even rate, this is in most
    models, a failure in the high voltage output. The common cause is
    failure of the flyback, and or the horizontal output transistor. If
    one or both of these parts have failed, there may also be some failed
    components in the power supply as well.

    After changing the defective parts, the cause of the failure must be
    found before putting the power back on. It is very common that some
    capacitors and support components to be changed as well.

    You should give the set to a service center that is qualified to work
    on Sony sets. They would be able to properly service the set for you.
