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.

This tends to be the result of an electrolytic capacitor somewhere, either on the main board or the power supply board bursting due to overheating. In this case you can pull off the back paneling and review the boards over to make sure all the capacitors are in excellent condition. After identifying a bad capacitor you can buy one from an electronics store in the area or a reputable online source. To replace it this will require soldering. Look for a capacitor with the same uF, the voltage can be the same or higher. Make sure all the power is out of the system before servicing, also make sure to note capacitor polarity observing the negative indicator line on the side. If your not sure this can be done at home I would recommend taking it in to a servicing shop. If you do not know what a capacitor looks like do a google image seatch for both examples of a good and bad copacitor. I honestly hope it's something much simpler, I hope this helped and good luck.
