I'm sorry you're having trouble with it, I need more info to troubleshoot the problem.
1- Could you please get me the complete model number written on back cover or side panel of TV?
2- What video devices/ sources (such as cable box DVD player etc) are connected to TV and does the problem occur on all video input sources?

Thanks for the info, this model is notorious for backlight LEDs failure that made screen dark, however, lets try easy thing first that might work..

- Have you tried to disconnect TV and cable box power cords from power outlet for 10 minutes to reset, replug back in, let cable box reboot that may take several minutes and check?
If not yet, please try it now.

If problem still persist then I'm afraid it would be backlight LEDs failure and least likely the power board failure that provides high volts to backlight LEDs. Please reply back with above requested test to proceed further.
