From the information you have provided failed capacitors in the power supply is likely causing the problem. The safety circuitry shuts the TV set down when it detects a problem. This model of TV has over 2,000 parts which include millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Integrated circuits and transistors can go bad. This can cause other components to become defective, which can have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again since if the parts that caused the failure to begin with are not replaced. The only way to know for sure what is causing the problem, which parts that are no longer within factory specs and for proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment. The repair should cost about $250 if carried into a TV repair shop. A small TV repair shop will often charge less than a large repair facility.

Power light and opc lights blinking green


It can be the power supply is sensing short circuits in the power supply itself or in the backlight inverter board, those are the two areas you need to inspect.
