How old is it? You could take it back to the store under warranty or CGA. If not take it to a TV repair shop. Sounds like something is up with the power supply.

Have you checked if the menu shows up on screen?
Have you tried changing the input to something else?

Might be something silly like no input

I bet if you press the button to turn it on, that it will start up in about 15->20 minutes. If it does, it will get worse with the amount of time it takes increasing until the point where you leave it on 24/7 until its replacement gets delivered, as you will be too scared to turn it off.

Is it an LED or CCFL backlight?

How good are you with electronics? You could take it apart and see if the power supply is delivering power to the backlight. Just be careful as these can be very high voltage for CCFL. I think LED is usually 12v on most screens for LED backlight? Most screens have 2x backlights (top and bottom) so its highly unlikely both just failed. Could be as simple as replacing a capacitor on the power supply.

I fixed a screen the other day where the cable from the end of the CCFL had somehow frayed and disconnected from the lamp with maybe a 1cm gap. It was arcing and causing the screen to melt and smoke (screen did work though!). I resoldered a new cable but shows that it must have been a decent voltage to arc that distance....

You should still be getting sound if it's only the backlight.
