1. You have a power circuit issue in the start up circuit of the power supply on the main board. There is possibly a weak or leaky rectifier diode array and or a capacitor. Your set needs to be serviced. It will go off completely soon.

This is a classic switchmode power supply, shutting down to avoid a fire, explosion, or both. This set had developed a problem, that is so severe that the set must be shut down, This set should be removed from the Power, and in my professional recommendation, you should get a "Quote" for repair, from, an Sony Approved Service Center, this point is very important for a good result, Always contact, their local, "Head Office" Now, when you get the information you want, then you can decide as to repair of replacement. The reason we want an approved agent, is that way, all the engineers are trained on their own brand sets, they have seen almost all faults, and will get the job done quicker, and for less cost, and usually have parts on hand,
