First of all please unplug the TV for an hour or more. If this power reset does not allow the TV to turn on component failure is indicated. These sets are assembled using the wave soldering process they are known for having cold solder connections. 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 affect 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 and for proper repair all the electronics must be diagnosed with the correct electronic test equipment and the correct skills to use the test equipment.
If you want to repair it yourself then you must be having an oscilloscope and has a knowledge to operate it.
If you decide this is not something that you can do it yourself then this repair will be about $100 to $300. If the problem is a bad circuit board, and if the board can be repaired or has to be replaced. A small TV repair shop will often charge less for the repair than a large electronics repair facility.
Please do accept this solution and revert for further assistance.
