hello!the problem is not on the power cord it is on the backlight of your tv (a cold cathode lamp)this needs to be replace you can reach the cathode lamp by disassembling the screen/monitor of your tv the lamp is place at the top and bottom of the screen be very careful when doing this.replacement is available online at shopjimmy.com.
sometimes the problem is on the inverterboard the inverterboard is the one supplying a current to the lamp the input voltage of the inverterboard is 24v so you have to check the input voltage from the power supply to the inverter board.a poor solder from the terminal post of the power supply to the inverterboard will also cause the problem.so resolder them.reminder..always unplug the tv before working on it..goodluck!A four thumbs up is much appreciated for answering your free question..
power pack capacitors have failed they will need to be replaced with new ones and that should repair the tv, soldering skill is required to do this or replacement of the entire power pack. hope this helps
