Hello
Check the backlight inverter board to your TV. This is a common fault for most of the LCD TVs. If it is faulty, the backlight won't light up, resulting a balck screen with sound.
This is the picture of the backlight inverter board to your TV. OK.
Surely there is a short circuit inside the circuit board. The most common fault is the short circuit witth backlight inverter board. If any short circuit deteced by the main system control IC, it will shut down the power supply secondary voltage. and there will be a standby light ON, indicating the power inverter board is OK. Check the backlight inverter baord for short circuit. If you haven't any idea about the electronic circuit, you can't do anything with this fault to your TV. If you have sound knoledge in electronics, and have some expereince to do the work, inform me. I'll assist you. But you must have the ability to follow me. OK.
