The Backlights inverter, the T-CON,or the 24vdc power supply may have gone out, it will require in-depth troubleshooting. Please read below:
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

if you do not have the directions. first manually turn on the set. then i find the code button. it may not say the same thing but it will be similar in words. push code, then push tv, then repeatedly push power until the set goes off then find enter(or something similar). this is an automatic code find technique.

You're better off just replacing the TV because of cost. If it is still under warranty why not contact the dealer you bought it from for an authorized service center location.

I'm guessing a power surge from the returning power burned something up. You should have all your electronics plugged into surge protectors at a minimum. The best protection is a UPS (uninterruptable power supply).
