There is definitely a power problem. It will probably wave to be taken to a repair service and fixed.

The TV is in protect mode.

Try unplugging power cord for ten minutes or so, and see if this help.

If the TV does not restart, then try unplugging for longer.

If still no luck then that means that there is an internal fault, let me know if you get the led blinking a number of times, or if there is an error code message on the TV display.

    In particular , regarding your case,

    TWO Blinks---B+ over current protection (OCP) , unit goes to the standby

    mode then displays the 2 blink fault. Could be a short in the power supply of

    any of the circuits.

    That means that if the TV does not restart after unplugging overnight, that means that the power board must be replaced.

    Note: it is not the main fuse, when it is the fuse you get no power at all, 2 blinks means : protection after overvoltage from power adapter.

    Often you fix this by leaving TV unplugged for some hours, until you drain power completely.

    If it is still the same, wait longer.

    If the over voltage had been occasional (eg. power surge can give you this) , then after draining power completely, TV will restart.

    This is only if you are lucky enough and TV is not broken.

    If TV does not restart the bad voltage that started protection circuit (led blinking and TV not starting), was caused by a bad power board, probably one of the 3, 5 or 7 (depending on network voltage and model) high voltage capacitors on power board.


    In this case the TV keeps in stand by so that the protection switch can save the rest of the circuits from being damaged by a faulty power board.

    If it does not restart, you will need to call a technician to fix it.

    You can call support by ringing the phone number listed on the owner manual.

    If you call Sony, ask them also the cost for a warranty extension, this is generally less expensive than a single repair job, and can cover all repair costs for one extra year.

    You can refuse my opinion, but I think I have been enough clear, the TV has a malfunction related to a power board problem, and must be fixed by a qualified technician.

    I also re-post my previous comment for better clarity:

    been occasional (eg. power surge can give you this) , then after

    No what? You have a faulty power board, 2 blinks, and no restart after har reset (unplugging procedure) is just a faulty power board.

    Here is the faulty part, if you have a good experience in fixing electronics, then you can do the job yourself, if not call the technician.

    And no what!?

    And do not forget to ask Sony the cost of guaranty extension, it will be probably cheaper than the cost of the single part.


    Thanks for using Fixya.
