How can I get the picture back?

many things can cause this problem it could be a frame fault as the picture is blanked out to protect the tube from screen burn not a expentive fault or the back of the tube is not lit called tube heaters or it could be a decoder fault there maybe an a1 voltage missing about 500 volts to the tube as your led flashes sony tvs generate an error code and depending on how many times it blicks that would determine what was susspect to an engineer its worth having it checked as long as you are not getting a bright screen red green or blue before the screen goes blank as i have known sony tubes to be at fault
