Is there any power indicator lit on the panel of your TV ?If no then the power supply is totally dead.You can take out the power supply board and have it repair or you can rep[lace the whole power supply board It is available online at shoppejimmy .com here's the link
browse your model,brand and part no.
usually the faulty in a power supply board are the regulators they are mounted on the board with heatsink use a multimeter to test them set the multimeter to a resistance reading.measure each pin all pins must not have a reverse reading .in forward bias they have a reading when reverse it should read zero means the part is good.measure also the resistors near the regulators they are measured in resistance if measured open resistor is bad with resistance,it is good.resolder all the components at the power supply board cold solder often cause this problem...
NOTE:be sure to unplug the TV before performing the repair...
