OK, can you try another video source such as DVD or Bluray player to see if problem occurs or TV works fine with it?
This test will help to figure out is the problem within TV or cable box is causing the problem.
No problem, take your time and try DVD test in your convenient time to see the result which will help to troubleshoot the problem.
OK, it seems backlight turns Off for some reason that made screen dark, we need to do another test to confirm it. Please grab a good flashlight and shine it on screen bit closely, if you observe faint/ dim image inside screen while TV is On and program sound comes from TV that means backlight has turned Off for some reason and causing the dark screen problem.
At this point there are two suspected circuit boards, either power supply/ backlight inverter board is defective or main board is failing and turns Off backlight system. Swapping the power supply board in TV will help to resolve the issue. Please click following link to view power supply bard image and get the part number off of power supply board to search/ google it to get price info to order it..
