Hi,

What is the model number of the TV?

Is there still audio when the screen turns black?

Try shining a torch at an angle close to the screen when the TV is on to check if you can detect any images at all on the screen. They will be very faint so trying this in a darkened room may help to see them if they are there.

If they are there then there is a backlight problem.
