It sounds like you've done some initial troubleshooting steps to try and determine the cause of the problem with your TV.
Based on the symptoms you've described, it's likely that the issue is with either the power supply board or the main control board.
The power supply board is responsible for providing power to the various components of the TV, and if it's not functioning properly, it can prevent the backlight from turning on, resulting in a black screen. Similarly, if the main control board is not functioning properly, it can prevent the TV from displaying a picture and produce no sound.
To determine which of these components is causing the problem, you can try the following: -Disconnect all cables from the back of the TV, including the power cord, then press and hold the power button on the TV for a minute. Connect the power cord back and turn the TV on. -Check the voltage of the power supply board to ensure it is providing the correct voltage to the main control board. -Check the continuity of the backlight LED strips to ensure they are not open. -Check the continuity of the ribbon cables from main board to the panel. -By checking all of this you could eliminate the possibility of a simple problem, If all of the above steps don't work, it's likely that one of the boards is faulty and needs to be replaced.
It would be best to get a professional to diagnose and repair the TV, as working with the inner components of the TV can be dangerous and may cause further damage if not handled properly.
Check the connections: Make sure all the cables connecting your TV to external devices are properly plugged in and secure.
Adjust the backlight settings: Access the TV's settings menu and look for the backlight settings. Try adjusting the brightness and contrast to see if it affects the picture.
Check the power supply board: If the TV is not receiving sufficient power, it can cause issues with the backlight. Check the power supply board for any signs of damage or wear, and replace it if necessary.
Test the backlight: Use a flashlight to shine on the screen and see if there is any image. If there is an image, it is a good indication that the backlight is not functioning properly.
Replace the backlight: If you have confirmed that the backlight is faulty, it may need to be replaced. This is a more complicated repair and may require professional help.
If none of these steps work, it is possible that the issue is more complex and may require further troubleshooting or repair.
