This sounds like the inverter which powers the display fluorescent has or is failed/failing. If you take a torch to the blacked out display can you see the image faintly? If so the unit needs repairing.
HelloCheck the backlight inverter board. If it has damged, most common fault to LCD TVs, there will be no backlight to the LCD screen, and will look black. Your tV has sound output without picture. This means that all other boards ar functioning well. Check the backlight inverter section and CCFL tubes used in backlight assembly. OK.
